Something tells me that data is related to accidents on the road and doesn't have much to do with motocross.

I have not read all of the posts yet, but have some. I will say, there was a race at one of the SMX rounds either last year or the first year, and RC and Aussie guy (Diffy?) were announcing, and they ran the 85's at that race and it was televised. THE 85'S were racing the same SMX track with all the big jumps and chop and ruts. 

During the race kids are crashing and dropping like flys. When it was caught on camera, they would switch cameras and not say anything. But, there was a kid in the top 3, and he was running well, clearing the massive jumps, which you had to do to run in that top 5, so Diffy starts talking about how he had a race in Florida or somewhere the next day. And how his dad would be driving the motorhome all night while his child sleeps after the race to get him there. But you know what happens next, the kid has a horrific crash on camera while talking about this, and its so bad, he's injured and they cart him off. 

Diffy and RC quickly move onto another rider, since the kid they focused on wouldn't be travelling overnight to his next race, but rather a short hop in an ambulance to the local hospital.

Fact was, the track never should've raced those 85's, and becasue the top 5 - 10 were clearing huge jumps and handling the chop and ruts, all the kids who wanted to be competitive had to. It was too much and a lot of kids ended their night early, some very injured.

I remember the 70's and all the rage was 3 wheelers. We had some. They killed a lot of people in the US in a short amount of time. Sure enough, the government stepped in, basically outlawed them in the US, and just like that, they disappeared. 

 

I think I remember this, pretty sure you’re talking about Canyon Richards. Only clip I can find is this one at 1:35:

https://youtu.be/boIOiP2RgGY?si=HpDeo3tRh5Bw5H31

That could the one. I just remember the camera following for about 2 laps as Diffy and RC talked about his race the very next day and his dad doing an over nighter with the RV to get him there as as they're talking about that and showing him on camera, he crashed pretty hard. Bad enough he wasn't going to that next race. I believe that is him.

There were riders in that 85 class going down left and right. It was carnage unfortunately

Do you have data from the 70s, 80s, 90s, 00s, 10s and 20s showing the number of injuries and deaths from dirt bike related accidents?

I’ve been riding and racing dirt bikes newrly all of the above decades and there’s never not been injury and death in this sport. Has it increased so dramatically that somehow the risk involved is completely out of control? No.

Motocross is what it is because of the inherent risk. Buy a set of golf clubs if you want to avoid risk.

You made the claim, not me.  I figured you had the data.

I do have enough common sense to understand that bikes that are WAY more powerful and WAY more capable going speeds and doing jumps that couldn't even be fathomed back then are causing more injuries though.

The world may never know.

What I do know is that I agree with the folks saying if we do nothing then something will be done for us.  I think the current insurance situation is proof of that.

This didn't actually happen.

The manufacturers signed a consent decree, there was no actual government ban. 

They switched to 4 wheels via that decree. Deaths have climbed higher and higher year over year on those four wheelers. 

Not making 3 wheelers anymore just took away the government/media spotlight, but it didn't save anyone, in fact... kind of like the 4 stroke argument here, ATVs just got immensely faster, easier to ride, heavier, and more dangerous.

I would love to have this debate with you based on relevant facts & information.

 

Most of the deaths are from getting hit by anotjer bike or ran over. Not from hitting a sketchy jump

What really cultivated my love for Motocross 20+ years ago is the grit and determination it took. Nowadays, it takes extreme precision, with little room for error.


Bring back grass tracks.

Correct.  Or hitting an obstacle like a pole etc.  I hate seeing any injury, much less a fatality, but the top speeds are not much different over the years.  Acceleration is vastly different, but if you look at the pro level, the injuries we all actually watch happen are rarely because of speed.  The other ones, like the recent one, we don't have video of and don't know what happened.

Oh bullshit. The bikes and the tracks have changed massively, and the risks have gone up along with them. Don't be stupid.

If you have access to one and someplace to try this out take something like an XR250 out in a field and lay out a course with some ribbon.  No (or minimal) jumps, just a fun easy to ride track.  Obviously the bike has worlds less suspension and power and this is gonna seem really lame but ride for about 1/2 hour.  I'll bet anything you have a bigger smile on your face than you've had on any modern bike in years, and if you have friends there it'll quickly turn into who can spin the fastest lap.  This is what motocross was like when a lot of us started.  The XR actually has 6 more horsepower than a stock '73 125 Elsinore (best bike ever by the way), way better suspension and handling, and we all thought the Elsie was a gift from god.  It's not the power or suspension of modern bikes that make this sport fun, and it's certainly with out question not modern tracks.  It's hanging out with your friends, riding at the limit of your ability and fitness and having fun.  Unfortunately we've lost sight of this and created a monster that we don't seem to be able to unwind and like others on here I'm afraid others are going to fix the problem for us. 

I know exactly the kind of experience you're talking about. When I was 15 in the mid 80's I remember being at my friend's farm where he had a backyard track (I there were 2 mild (by today's standards) jumps and something of a whoop section, otherwise pretty much a turn track). There were 6 of us there. I had an IT 200 - not a motocross bike, but I thought it was awesome. One guy had an XR 200R (about the same year as my IT, which was an 86). He was hitting jumps so fast that when he landed there would be a loud clang and I was sure that the bike would break in half - but it didn't. Another guy had an early 80s YZ100, and I remember thinking it had a wild powerband with basically no low end power (my IT was torquey) but good top end hit. One guy had an XL 350 - it wasn't exactly made for jumping, but he was holding his own. And another guy had an old bike from the 70s - I don't remember what it was - but he was hammering through the rough sections and his hands were literally bleeding afterwards (he was a tough bastard!). f you looked at what we were doing through modern eyes - being used to modern bikes on modern tracks - what we were doing would look ridiculous. I thought we were going fast. We really weren't. But I can't remember ever having more fun. 

That was almost 40 years ago but it still feels like yesterday. I think the reason it's seared into my memory because the next time I went riding - a trail ride- with some guys from that group, one of those guys was killed a hundred or so feet in front of me in a collision at a blind intersection on an old dirt road where there was hardly ever traffic - but there was that day, at exactly the wrong time. I hardly rode after that, and then  a few years later sold my bike and went over 20 years without touching a dirt bike. Even the thought of it caused me to feel a certain amount of fear (the trauma of that experience messed me up in various ways - people always noticed how I tended to slow down and check for traffic even at controlled intersections when I had the right of way).  When I got into my early 40s and the kids got older and I had more free time, I decided I needed a hobby.  I remembered the fun I used to have riding, but I also was struck by the fear and trauma that seeing that accident and losing my friend caused me. I decided to embrace the fun and give a big fat middle finger to my fears by riding again - I'd had enough of being limited by my fears. I know it's not safe. Life isn't safe, but I want to be alive while I'm living. That doesn't mean that I'm interested in taking crazy risks. I ride fairly cautiously. I try to mitigate risks but I know that risks can't be eliminated. If the tragedy associated with our sport is too much for you, believe me, I get it. But I'm back riding. I have Parkinson's disease now so I know the number of years where I can keep doing it are limited. So I plan to enjoy them while I can. In doing so, I'm going back to a simpler mindset - I don't want to spend my riding days testing new parts or chasing suspension settings. Because of my physical limitations, I'm riding at a slow pace (on a KTM 450 factory edition - yes, I'm one of "those guys", who might as well be on an XR400 - I really don't care if it looks silly).. But that's ok. I want to do what I did 40 years ago and just ride and take in the sheer joy of it - the joy that I experienced before a tragic accident robbed me of the ability to experience that joy, and that I know Parkinson's will take from me again at some point (something's going to get all of us so don't feel sorry for me). I think my friend would be pleased.

I would like to see amateur races run two thirty minute motos. I hated racing those 4-5 lap races as a kid. If people weren’t going all out, I think it might help a bit. Lowering the displacement might help a bit. Some tracks are more dangerous than others. At the end of the day you’re flying around on a motorcycle, though.

I didn't ride for about 20 years and then recently did a track day on a 450. I had an absolute blast and I could go "fast" with way less effort than when I last rode a 125. That meant less armpump and more laps. I also rolled every single jump because why the fuck are there multiple 60 to 100 ft jumps on a practice track? A well designed track with sweepers, rollers, tight bends, berms, some tables, and a fast straight or two is all you need! If you can't enjoy Moto without absolutely sending it on massive jumps you might just be a headcase with a bike rather than a fan of the sport.

Where should you practice big jumps so you can do it before you have to do it on a race track if not on the practice track?.


Different riders and ages have different needs on a track. If you build a real racetrack the VET riders complain, if you tame it down the riders that compete complain. 

And not all clubs have the land and resources to build multiple tracks. So you build a track to suit as much riders as possible but you always end up with unsatisfied riders no matter what you do.


I have built a couple of tracks and helped some clubs with new track design and both building and re-building old tracks and it’s always the same problem to find the perfect happy medium.

Has anyone seen a track built with alternate lines to go around big jumps? Merging the two lines back together could get interesting, but that would keep the jumpers and us older “grounded” riders happy..

Motoland in Kingsbury, IN has this in a 3 jump section, but unfortunately the owner is MIA - great tracks.

We were JUST having that discussion over dinner. We saw the specs on the new Ducati and that started it. Plus the Zingg tradegy, another in a recent line of them. My 19 year old (racing since 5) is firmly in the camp of enough is enough. He thinks setting HP limits of 30 for 125s, 40 for 250s, and 50 for 450s would be reasonable. He rides street too and says his CBR500R at 60 HP is enough most of the time. I've ridden and raced for 40+ years and the new gen of MX is too much, although a good 250 is perfect for a 190 lb Vet. I had an MT-09 (modded pretty well) for a year at about 100 HO and it was too much. My 1979 Daytona Special is about 45, and that's not enough. Hell, UTVs are making 250 and people have wadded them bad. Another target for the insurance companies - we better do this on our own terms, first.

It'll be impossible to enforce HP, especially at amateur events, and it doesn't allow the manufacturers and aftermarket companies to innovate.

If we simply set maximum displacement, which can easily be tested, it allows the manufacturers to innovate and compete with each other, yet the baseline HP is reasonable.

I've written up and posted a plan to make the transition smooth a few times, for both the pro and amateur sides.  I'll see if I can find it and post it here later.

BTW: I'm a 63 and have always ridden a 125.  I set my own limits, because I know that if I have a 450, I will use it.

Ive got a ktm 450sxf stock and a ktm150sx with a pipe and a keihin carb.

Both bikes are really fast, one is super easy to ride and one is really scary to ride with a come to Jesus moment every lap.....

But never let people's real world experience get in the way of how you think the world works.

The only thing that has ever and will ever cause injuries is the monkey twisting the right-hand grip.

I'm in the camp of the current bikes are so easy to ride they easily fool riders into thinking they are more skilled than they really are.  That leads to getting WAY over your head in speed, skill, and reaction times and leads to big crashes.  Throw in tracks that cater to the crowd of riders always wanting the "big booter" so they can display their testicular fortitude and you've got problems.  Sometimes we ARE our own worst enemy.

The track problem is pretty easily solved but requires a little bit of land and probably some additional cost.  Since the loud crowd basically wants outdoor supercross tracks, create one.  But to ride it, you need a license from a certified trainer.  For the rest of the mortals that need to work, give us all as natural an outdoor track as possible.  Any jumps should be limited to tabletops...no gaps and no ridiculous lengths.  Let the track get rough to slow it down.  And I'm all for sound/power reductions too.  It wasn't that long ago that the 250 2 stroke was the premier class bike and they survived just fine on 40-45 HP.

People keep saying the sport was just as dangerous years ago as it is now as if this somehow makes it OK. Every other motorsport you can think of has become much safer over the last few decades. Moto is the only one that tolerates the same level of safety of two generations ago and doesn't see the problem.

No, it wouldn't. There's already plenty of ECUs in the car world that limit HP output for valet use, or inexperienced drivers.  Require use of an unmodified OEM ECU that has limits enforced. Problem solved. Ban engine mods that increase HP. Allow suspension, chassis, and brake mods. As it is we are "innovating" ourselves out of existence. 

We are playing a lot of golf now. Damn difficult sport (I'm a 13 handicap) but it's funny - my boy has played maybe 15 rounds now without one ambulance ride, not even a scratch. And he loves it. When he leaves with his clubs in the truck I don't worry about getting a call that he's wadded it up (again) and is hurt. I do admit that I miss watching him in the "flow", hole-shotting every moto of the weekend at Washougal, running with the fast group. I think those days are over for us.

In 10-15 years ago we had a couple of deaths during the summer here in Sweden.

After that we raised the age for being able to go pro from 15 to 17 I think it was and pushed hard for a class called 125 U17.

We don’t run superminis in Europe so we ride 85’s and the next step is 125. We had a class called 125U (U stands for ungdom that is the Swedish word for youth) that riders between 14-16 could run.

And that worked fine until 2004 when Honda/Kawi/Suzuki released their 250fs and our sanction body re-named the 125U class to MX2U and allowed 250f’s in to it.

Now letting 50kg 14 year old kids racing 250f’s, and we don’t have stock or mod classes, it’s free mods.

And there things started to go south. Kids went from 85’s to full mod 250’s at the year of 14, raced one year and then turned pro at 15 and were now racing the Swedish championship against full grown men.

One of the deaths happened at a Swedish championship round, a 15 year old fresh pro rider went down in the start and got ran over and passed away.

That started a talk about the bikes were to fast for the small kids and that their bodies maybe were to small and fragile for the forces that could occur.

So for the next season they created the 125 U17 class, keeping the kids on 125’s instead of 250’fs until the age of 17, giving them a couple of years on big wheels without the power and weight of the 250f.

The U17 class got a place at the Swedish championship, letting the 125 riders to race on the same weekend as the 250f and 450f class in the same way as the EMX125 class races at the MXGP weekends. 

That has had a positive impact on the accidents here in Sweden. Giving them some extra years to prepare and to grow in to their own bodies.


The sport is still dangerous and accidents will happen, but I agree that the bikes are getting to fast. The 250f’s are leaps faster than the 250 two strokes that were the main class for 20-25 years ago. Both in power and rideability. 

I wish that we could go back to 125’s as the small class and 250f’s as the main class. That would also keep the costs down a bit for the bikes in the little class. 

Someone will now say that it’s less accidents in the 450 class but 99% of the riders in that class are more mature and that probably keeps the statistics down.

I was there that day, I used to race for all my youth - about 15 years - we went all over sweden and some races abroad. I dont regret it for a second, I still had a bike and rode at the time of that shitty day in Västerås, i had my two kids with me and we stood right by the start corner. After that day i rode maybe twice again - that was it for me. Johan was such a promising young rider.

People keep saying the sport was just as dangerous years ago as it is now as if this somehow makes it OK. Every other motorsport you can think of has become much safer over the last few decades. Moto is the only one that tolerates the same level of safety of two generations ago and doesn't see the problem. 

That’s a really good thought….👍🏻💯

No, it wouldn't. There's already plenty of ECUs in the car world that limit HP output for valet use, or inexperienced drivers.  Require use of an unmodified OEM ECU that has limits enforced. Problem solved. Ban engine mods that increase HP. Allow suspension, chassis, and brake mods. As it is we are "innovating" ourselves out of existence. 

We are playing a lot of golf now. Damn difficult sport (I'm a 13 handicap) but it's funny - my boy has played maybe 15 rounds now without one ambulance ride, not even a scratch. And he loves it. When he leaves with his clubs in the truck I don't worry about getting a call that he's wadded it up (again) and is hurt. I do admit that I miss watching him in the "flow", hole-shotting every moto of the weekend at Washougal, running with the fast group. I think those days are over for us.

Good for you man.💯👍🏻

I will tack on that I have quit riding altogether pretty much since Jerry Robbin.  I had big plans for my year and my bike has been collecting dust since late April/early May.


There have been more devastating injuries and deaths this year than I can ever remember.  I’m over it man.  I’m sick of this happening to people and it just doesn’t feel worth it.

I made a thread in non-moto about karting the other week, I’m selling the bike to switch over to that for now. Is that dangerous too? Well...

I made a thread in non-moto about karting the other week, I’m selling the bike to switch over to that for now. 

Is that dangerous too? Well, sure, someone just died at a karting track yesterday. But with so many incidents in moto lately (Jerry Robin, Matt Buyten, Reed’s daughter, Trevor Colip, Mike Brown, now Aidan Zingg), the urge to go out and ride moto just isn’t there right now.

The safety just hasn’t evolved at the same rate as the speed. Neck braces are rarely seen these days, Alpinestars has the inflatable vest, but how many riders are wearing one on any given weekend? 

I don’t know what the catalyst will be that will spark some mandatory safety measures being implemented… but we can’t just hide behind “it’s a dangerous sport” anymore. Auto racing is a dangerous sport. NASCAR implemented the HANS device after Dale died, drivers complained about restricted movement, but how many deaths have there been in NASCAR since it’s inception? Formula racing introduced the halo, drivers complained about the visibility, but how many times has it saved lives already (Grosjean fiery crash, Zhou’s flip, Max landing on Lewis’ head). 

Now look at all the issues that happened just in this last year, the threads posted recently about giving it up or slowing the bikes down, just for the sport to continue down the same path as always… Sadly, at this point, I’m afraid it’s going to take a highly-publicized incident involving a top rider for some actual change to take place. Time will tell.

Top riders have had horrific injuries and nothing changed.  Magoo, David Bailey, Ernesto Fonseca, Jimmy Button are a few that come to mind.

There are a few easy solutions to slow the bikes down. That doesn't cost much to the manufacturers.

1. Sound limits - Drastically reduce the db's and set the test limits to a much higher rpm/throttle position

2. Introduce RPM limitations - drop 2000 rpms from the 250 current peaks of around 14,000 and reduce the 450's to 10500 and 350 to 11250.

3. Intake size limitation - reduce the throttle body outlet diameter by 1-2 mm on the 250-350f's to force a more torque approach to the motors and not the continuous push for rpm's and peak.

I think the aim should be to get back to the 2008-2012 ish dyno numbers with a drastic sound change.

It's easier to simply restrict displacement, then let the factories and aftermarket companies continue to innovate, differentiate and compete with each other.  It's worked for Nascar and Indy, and I believe they've lowered displacement more than once.

The rest can be done as well.  Lowering sound levels would help tracks stay open, but lowering displacement is easier.

Besides, It's too easy to cheat with RPMs, etc... As Hammer suggested, we can require a stock ECU, but people will find a way to hack those too.

Yes. I’m looking for off road data without success. This is the closest I found so far

Note: Mammoth is at 8,000 feet and the the afternoon on a hot day. bikes can lose  massive HP due to altitude. Add density altitude on a 78 degree day and it is near 11,200 (11,187ft) feet. On a built 250F pushing 48HP this is approx. 3% for each 1,000 gain. Math makes it 33.56% That puts HP in the 30's.  Approximately 31.9 horsepower at 11,187 feet density altitude to be accurate.

Jumps are much bigger though. Grooming has changed as well, with track prep much different than 30 years ago. Yes, I’m old
