I can see how that could be benificial in some situations
More training and practicing than racing
, i would like a gear indicator ive always though that
, and honestly id like less gears
I just read some where that some pro's run 4 and even 3
Speed transmissions
I think i and a lot of amateurs could benifit from having to shift less .
Suzuki tried this with their original 450f didnt they? And everyone bitched and hated it. Even tho ur right, most of us just use 3 gears on the track.

Heck, I only use 2 gears after the start. I hate shifting and never really saw the point in rev'ing a 4 stroke to the moon. If I can go the same speed but a gear higher (and the suspension works better at low rev's) what does it matter? Not to mention, I change my oil on my bike way less than the average person. Every 30+ hours on my FE350. It's a win win all the way around.

I wish the mfg's would go back to experimenting with less gears on their showroom bikes. 6 speeds are so unnecessary.

(I cant believe a serious discussion came out of this ridiculous thread)

The majority of current motocross bikes come with five-speeds, not six-speeds actually.

The original KX450F was a four-speed, as was the KTM 450SX-F for a while. The 450SX-F in Europe currently has a four as well.

If you understand physics trajectory has nothing to do with rpms. You cold rev the engine at 10k sitting on the face of the jump you need velocity

Trajectory physics?

Dude, you're talking about a speedometer for a motocross bike. Nothing could be more pointless. How do you measure mph? Rotation of the front or rear tire? How is that information useful given how often you break traction on a motocross bike?

Zen,
Who said velocity must be measured at the wheels? Any ways wheel velocity is known as angular velocity. U guys are falling on your faces trying to disprove speedos

I don't think it really needs to be disproved. The general consensus is it's a bad idea. If you want to do it then by all means, go ahead. Nobody is going to stop you.

How else are you going to get real-time speed info, if not measured from the wheels or the engine? I suppose you could wear a highly sensitive GPS unit, but then why add the unnecessary weight, complexity, and most importantly, cost?

All the evidence we need to "disprove" the need for speedos in motocross is to look at what people use (or don't use). If there really was a need for one, you'd see them everywhere. By your own admission, you couldn't find one for sale at the time that you made this thread. What does that tell you?

You're falling on your face trying to prove that speedos are needed or beneficial. I'm pretty sure that burden of proof falls on you.

You are claiming it's a bad idea without any real time testing. If a pro used a speedo I'm sure every squid would follow.

If you can't judge the speed needed to clear a jump after rolling it a couple of times, then it's probably in your best interest not to hit the jump, speedometer or not. If you need a speedometer to tell you if you can hit a jump, I can't imagine your skills in the air are that remarkable.
12/14/2015 9:08pm Edited Date/Time 12/14/2015 9:14pm
Ok, you installed a speedometer. Now what speed do you hit it at? The guy clearing the triple can't tell you because he doesn't have one. Time to calculate the angle of the jump face, distance to the landing, angle of landing, projected trajectory, wind speed/air resistance, earth's rotation speed, angle of the moon, when you shit last, and so on. So add a Texas Instruments TI84+ to your shopping cart along with the speedometer.

PS, Someone call the Hoffman crew, this thread is GOLD.

Was it the recent Mike Healey podcast where one of his teams was asking him to run a tachometer to perfect his shifting points? Silly.

btw, on these 3 and 4 speed gearboxes, where is neutral? I'd hate to have to shift thru neutral so many times, and you can't put it at the bottom...or can you?

You can put it at the bottom. They just started doing that with MotoGP bikes this past season for the first time (in their case it's at the top). Everything is linear.

Im not sure the reason they did it (performance or convenience) or if it is some high tech that would be overkill for a dirtbike. But it can be done.

Dude you should stop. Do you even know what angular velocity is? Do you know how a speedometer works?

The most clear headed and realistic response yet. If you NEED a speedometer to help you judge how you need to hit a jump then you have NO business hitting the jump in the first place because I can already tell your skills aren't up to par enough for you to even be lifting your front tire off the ground. Before you get a speedometer I suggest you get some more practice or training before you get hurt!! No matter if you know EXACTLY the same speed someone else is going over the jump like everyone else has said the revs and what gear and how much throttle you have turned make the most difference other than your body position and skill. Exact Mph should be the very least of your worries

Tachometer, speedometer, temp and gas gauge. i would buy buy this gauge if one was for sale. I would do the triple if I knew what speed I needed to go. It's a speed issue that's why you need to follow someone over a big gap the first time.
Just use the gauges that are mounted to your quad

Bro, I believe this is a great idea. If only Seth Enslow had thought about it ... his career might have been very different.

Now you are ready to give Robby Maddison some competition ... Hey, Red Bull might sponsor you. As you can see on that picture, just make sure that you eliminate any vibration on the bike so you don't have a false reading of your speed.

While speed seems to be a major factor, there are other factors that come into play that determine trajectory/distance.
I think if you were wanting to use it for that purpose, you would be better off with a light system for letting you know what gear your in. But it seems that you're looking to use technology to replace practice induced skill.
You know what they say,
Amateurs practice till they get it right
Pros practice till they can't do it wrong

No I didn't miss his point at all. I guess you missed my point.

Speed is relative weather you are seat bouncing or using any other technic he was implying

Listening to the revs...this is very subjective. What does 3250 rpm sound like?
Go get some more seat time. Most guys can ride a track with there eyes closed. You can also hit jumps in different gears on these new 450s

Not a good idea last thing you want to be doing is looking down at handle bars/front fender when jumping.

How to clear a jump.

1. Roll the face of the jump a few times to get a FEEL for the angle, kicks/lips.

2. Under jump the landing to a safe spot getting a feel for the distance and more importantly speed in the run up to the jump. For example on a double you should be landing comfortably and consistently before the back side of the landing, table tops 3/4's of the way along. These landings will be harder than typically coming up short (safe though) but no worse than over jumping to the base of the landing as you will be carrying a lot more forward momentum if you over jump.

3. Grow a pair and carry you speed into the jump and all the way off the face. Make sure you get out of the corner or off of the previous jump and accelerate up to a speed that you FEEL will take you that extra 20-30ft to the sweet spot or even base of the landing.

4. If its not enough speed on say a double and you are going to case it, land with the power on and drive down through the landing under acceleration. Same goes for coming short on a tabletop. If you have done steps 1 & 2 and you can't gauge the additional speed or pre loading suspension for example you are not ready to even attempt the jump.


Speed in mph/kmh is useless to you. You would need to calculate difference in rider weights, how the rider soaks up or doesn't soak up the face of the jump with his/her legs, hit the exact same line (different lines can throw you long or short depending on kickers/worn out the lip is).

If you need to gauge the speed then ride beside a fast rider on the approach to the jump. Because typically most fast riders will have the speed to clear the jump way before the take off and are only maintaining speed on the last 30-40ft. If they are seat bouncing or ringing the neck out of the bike then it is a difficult jump to clear or needs a wider longer run up to approach safely. Now back to the speed. Because rider A is carrying X speed into the face doesn't mean to say you will require the same speed as per differences above.

What you also have to learn is the sound of the good riders leaving the face. Are they maintaining a steady throttle, accelerating moderately or hard. Thats where the old Braaaaaap discussions come in the pits for most experienced riders. A quick description of noise to most EXPERIENCED riders is enough to let them know how to attack or not attack a jump face.

I'm honestly starting to think this is a joke. Like a pro, I don't need a speedo because I use my ability formed from years and years of riding to judge my speed or trajectory or velocity or whatever the fuck it is you are looking for with your handlebar mounted speedo. I was trying to phrase it kindly in my previous posts, but I'm going to be real now. Your idea is fucking stupid. Wink
