I went to a local race today (just watching) and I
Was amazed at how everyone was doing most of the jumps
Especially a 30 foot or so triple
I didn't measure it but guessing ..anyway
I saw maybe 2 or 3 people on big bikes not hitting it
In the early to mid 90,s only the A and B riders would have been doing this jump
It looked intimidating to me
And there where people jumping it that looked like they had no business jumping it lol but still not crashing so there is that , but people with slower lap times to put it nicely ...
Must be the four strokes
Just make it easier I'm guessing ??

4 strokes are definitely part of why mid-pack C riders can clear every booter on the track. It's the rider's responsibility to ride within their skill level but that doesn't mean Joe Schmoe doesn't want to huck a fatty from time to time.

I don't really care about the 2 vs. 4 thing as I have owned both and both are fun to me.

4 strokes are definitely part of it. You didn’t really see beginners doing most of the jumps on their 125. But now, put those same guys on a 250f and they jump them no problem.

It’s definitely easier to go faster on a 4 stroke.

FYI - I highly doubt the triple you are talking about is 30 ft. A 30 ft table IMO is pretty small. Any triple should be in the +70 ft range (or much bigger).

I remember when I was about 14 I got my first 250f and immediately started doing jumps I normally wouldn't. I was a back of the pack beginner until 15. I think it has to do with how easy it is to guage a jump on a 4 stroke. Roll it on and sail

Sounds correct. Doubling it would be a harder landing.

Tarz see the same thing when I ride. Guys jumping things all looped, no skill but they still get it done.

I'm one of the big bike riders who doesn't jump everything. I'm female, and just don't the drive to win practice day trophies. Silly

My closest track is made by and for A/B riders. There really isn't much I feel comfortable trying. Most everyone clears every jump on the track, but I'm good only jumping halfway. Yesterday I spent a lot of time on the figure 8 track to keep out of the way of fast guys.

My favorite local-ish track (now closed) was ICR near Macon. The owners made every big jump so that slower riders could hit them and feel like they did something. The largest jump was shaped like a camel's back. You could land halfway on the down slope, or gradually increase your distance to clear to the second downslope. Before it closed I started hitting the whole length.

There was another double-ish style jump at the finish line that I did most of the time. It had a long straight leading to it, and a 150 straight into a sweeping left after. It was super safe.







Loved the dirt at ICR more than anything.

It is more than just 4-stroke power. The bikes themselves are so much better than even 10-15 years ago. Suspension and handling is so good that it gives beginners a huge advantage even starting out. And the new minis are on another planet compared to just a few years ago. You have kids that are huckin' triples on their 85s. Then they move up to the big bike novice class and they are flying straight away.

That's a point a lot of people overlook when they start complaining about beginners jumping everything on a track...the bikes are just so much better-right out of the box-and not just HP...but power delivery, handing, suspension, chassis development, etc. etc. That it just doesn't take as much skill to hit jumps any more.

Imagine what the guys from the double shock days, said about the beginner riders buying single shock bikes in the 80's..."those shocks take all the skill out of riding", "any beginner can get on one and go fast", "they are ruining racing...it's all about jumping now", "it takes no skill"...aka: all the same stuff guys now days say about the four strokes...and they blame the four strokes, but really they are just blaming bike progression.

I can't wait for electrics to take over so we can move away from 2st/4st debate and division of the last 15yrs.

I agree. Modern bikes are so easy to ride fast. They let you make mistakes that would have bit you hard a couple decades ago. I can’t believe how far along my 16 KX450F is compared to my 00 YZ426F. Honestly the new 450s seem to be very easy to ride and are very forgiving bikes. Something you would never say about the 500 smokers of yesterday.

And yesterday I was on my 450 all day, hopped on my buddies 17 YZ250, and sent the 90’ double first lap. So it’s definitely not a 2 v 4 debate, more like new v old. (To be fair I do own a 13 YZ250, it’s just in pieces right now)

Not sure on the math/angles, but jumps used to be less steep and more distance. Todays tracks mostly have jump faces that create height and suspension compression which results in distance. Never been a fan of the steeper jump faces, I suspect many of our Legends and Hero's feel the same way which is why so few of them race as Vets.

I Loved ICR! Those back to back triples on the front straight were great!

I remember one summer, I jumped that decent sized step up from the bottom section, and almost landed on a huge rattlesnake chilling on the track. Why did it ever close? Proximity to residence??

Yep. Older style were fly away jumps. Now they are launch jumps.

See if you are with me on this...

If I would have stayed on a 125 or 250 2 stroke instead of going to 250fs and 450s, there would have been plenty of jumps that I wouldn't have even thought about jumping. One thing I'm looking forward to with being back on a 250 2 stroke is the fact that I won't be tempted to jump certain things because I won't have the same power that I would on a 450. I'd have to hit everything perfect leading up to the jump just to even think about going for it, but with my 450 all I had to do was twist the throttle a little further and it carried me over almost everything. I see guys at the track all the time rolling slow through a corner then grab a handful and have no problem clearing jumps out of corners. Not the case with guys on 2 strokes

Maybe on a 125, but I don’t feel like I’m giving up much in the way of roll on power on a 250. It’s harder to find traction on the two stroke, but that’s about it. My YZ250 is so smooth, and has an incredible mid range, that it makes it a very easy to ride bike.

agreed, when the dirt is loamy a 250 2 stroker will blow the doors off a 250f

Yeah, ICR was a hour & a half drive for us but worth every minute when we got there. I switched to Bremen once ICR shut down (no idea why?) but grew weary of the hour+ haul... ended up getting a dual sport. Just got a 350 sxf and am restoring a 07 kx250 two stroke. Miss moto. Miss safe and less jumpy tracks more than anything.

Last time I rode ICR was in 2009, it was fun, but closed not too long after. I remember there was a double on the back straight I wouldnt jump on my 250F because my suspension was super soft (I was 220lbs), everything else I jumped within 3 or 4 laps. Did you guys ever ride Roost Creek/Iveys?

Was Roost Creek the spot just off 475? If its the place I'm thinking of, it was semi private, had to pay a yearly fee. Loved that track.

I've built a ton of jumps over the ears and the math/technique has always fascinated me. The final angle of the jump is only part of the equation the transition is possibly a bigger factor in what a jump face does. The bigger part of making a jump work is the landing but not as many builders understand that. A properly built jump that throws you up is safer than than one that throws you out since it slows the rider down.
Landings with convex faces verse concave. Large rounded landing decks that have enough break over so the frame doesn't catch if shorted, proper run out after a jump section, etc. all make things safer. It's not hard to make big safe jumps that beginners to pros can have fun on and be safe you just have to plan them out correctly.
Thumpers may be part of it but it's mostly just how times change. My kids jumped/jump things on 2-stroke minis that 20 years ago wouldn't have even been considered simply because it's common now. Suspension is also better but mostly it's just because riders see other riders doing it and learn from that. Look at the backflip. Once it was done once it quickly went from impossible to commonplace..........

Good ole Mankato ! The triple into the rollers is way easier than you think.

Those pictures of the ruts going down the hill don't do justice for how gnarley they were. I'm still surprised they even pulled the race off since there was still snow on the track on Thursday !

Southwick is the best track in new England, no big jumps you don't need big jumps to have a great track

Jump design has really evolved, just understanding how to build takeoffs and landings. Seeing the big air on television every week probably helps too, but I can remember seeing plenty of big jumps even back to the late 80s.

I think stock spring rates are part of it too. They have gone up a lot over the years. I look at rates on some of the vintage bikes I'm familiar with-- 85 KX 125 had .27 fork springs. 86 CR 500 .37. Now a 125 is at .42, my 250F came with a .47, 450s are a .49-.50 I think? I ride that 86 on modern tracks, and I can tell you when I had the stock springs, I wasn't even thinking about most big jumps because it would bottom even on the takeoffs! I upgraded to modern rates and now it's really not an issue to go for bigger air on that old bike.
