The bikes perform better in low rev -Emig

I remember emig saying something close to this during the hangtown 1st 450 moto when they were talking about villojoseph. He said that he keeps in low revs because everything on the bike works better. Suspension mainly. But i think he keeps it in a low gear for the wheel spin factor and the bike doesnt jump forward as much when you have it in a taller gear. So it would be easier in turns. But my beef with what emig said about the suspension working better in low revs doesnt jive with the 250 class because they are constantly on the limiter but they are running close to the same lap times?

i dont think the revs have much to do with suspension, maybe a little but not anything noticeable. but he has a pioint because you see K-ROCK winning and his motor isnt bouncing off the limiter like tomac or barcia used to do (and still kinda does) there is no point in revving the piss out of it in the air,

It's true...

Lower tension on the chain allows the suspension to work more freely... Which is why they say shift up to 4th and 5th in the whoops to get the wheel spinning high and allow the rear to bounce consistently...

Watch Barcia his first couple years in the 250 class, didn't look as good as ride as some of the other guys who shift it more... At a certain point you gotta rev it obviously, but there are situations where it helps if you're letting the bike roll more easily than putting tension through the rear

I thought it was funny how Emig said that RV keeps in it in such low RPMS. Cause every gopro I have seen of him he revs the bike more than anyone else. Like stewart who seems to cruise the motor.

I thought the exact same thing

450s have way more engine braking than 250s, even more so when running high comp pistons. The forces can unsettle the front end big time and that's why lugging works better

Try it with your car. Drive it in a lower gear through a bumpy road and then shift up and drive the same speed in a higher gear. You will notice the difference. When the wheel hits a bump and starts to spin near the rev limiter there is nothing that can drive it forward in lower gears. In a higher gear it will just find the drive higher up in the rpms. Thats what my logic tell me anyways.

soke riders are so annoying on the track.they raugh the crap out of this thing. they d go twice as fast if they wouldnt do that.

I'm pretty sure that translates to "SoCal riders are so annoying on the track, they rev(???) the crap out of this thing (meaning bikes maybe?) They'd go twice as fast if they didn't do that"

look at any vid of everts ride , low rpm works , same with windham , two of the most smooth riders ever , was surprised to here RV ride s low rpm , always thought he revs the bike a lot ,dungey def rides low rpm

You would be surprised. On a rough track where suspension setup is exposed keeping a bike in the meat of the power will be smoother. The suspension is allowed to work more freely and will have less tendency to pack up in the rough breaking/acceleration sections.

Emig is a technique guru. He knows his stuff. (Also a multiple time Ama mx champ)

Im no pro, but i notice the bike glides over bumps if im in the middle rpms, compared to being twitchy in the higher rpm range.

The engine has less effect on the bike's suspension if you keep the RPM's low. It's most evident on a road bike though. If you cruise around at high RPM and chop the throttle, the bike behaves a lot different. If you chop the throttle at low RPM, the bike behaves almost like nothing happens. I think that's the point Emig tries to make. Villopoto revs his bike just as much as anyone else I thought. I thought Reedy would be the best example of keeping it low out of the current riders. Villopoto seems to just be able to carry more speed through corners and get better traction to make up time. I doubt it's due to how he revs his bike though.

Momentum and acceleration are the two issues that define RPM usage

And with riders who get very nit picky about even the most seemingly trivial things, a small difference might mean a world of difference. But I agree, I can see the lower RPM's being more beneficial in certain situations.

They say to ride a 500c 2 stroke the best way is to keep the revs low - It reduced centrifugal forces making the bike easier to handle - Hold a Bicycle wheel at the axle and spin it then try to move it and see what Centrifugal are all about - Bigger the motor bigger the forces

Ah, low-rev. The new seat bounce.

Those centrifugal forces you are talking about. are what brings a bike back to straight from a whip. Thats why in the x games all you hear is the limiter to bring the bike back faster.

Yeah like here the only time you hear rev limiter is when RV is in the Air - Mostly he is maxing the Power with gear shifts ....

the word youre looking for is "some" not "socal". the letter K and the letter M are right next to each other on your keyboard...

When I first started riding 4 strokes Ross Maeda from Enzo could see that I was trying to rev too high through the whoops when he told me to shift up a gear higher through the rough stuff, and explained how my suspension would work much better. Went out and spun some more laps and did just that. Low and behold he was right. Ross is no dummy.
