Hi,

does our bike have a rev limiter ? When does it kick in ? Could not hit it and find that there is more power when I change the gear instead of reving in the red. Would like to know it anyway.

I have always read it does have a rev limiter.
All newer modern engines do.

As it should, this is part of the function of the rev limiter, go farther and it should disengage the clutch.

That can't be right, how is disengaging the clutch going to keep the engine from reving?
The rev limiter cuts the ignition to prevent any further rpm progress.

As my Venox is the first bike I have ever had that has a rev limiter am just stating what happens to me ... the clutch will disengage but I have never had the ignition cut out (??)

maybe I should have worded it differently.. as once the clutch disengages you can still keep reving it but why would you ? you are not going anywhere.

MAYBE its different with Hyosung.

That's just it, the object is to stop the bike from reving any more and damage the engine, it can't be left in the hands of the operator or it won't happen.

Hi again,

I tried it out. At 13k it kicks in, but very smooth. I was a bit scared it would would be as rough as in a car, but may be because it is reving that high, it is not much noticeable.

And it definetely is not the clutch doing anything, but the engine electronics is cutting out to prevent the engine from dying.

i so do hate to asssssume - but when you 'change the gear' to a higher gear? i've just flirted w/the redline and haven't hit the limiter. but i do not remember MORE power in the higher gear at the instant of change. throttling got more pretty quickly, though. . . good to know it's an easy feeling though . . . :bawl: i wanna go check this out nowwww :crap:

I've not hit the rev limiter on any vehicle I have riden or driven and I certainly don't know what a Venox does having never had the pleasure but I must agree with Serp - if it disengages the clutch without somehow also throttling back the engine it would actually increase the risk of destroying the engine since you would be in the situation of a wide open trottle and suddenly no load on the engine - this makes no sense, the engine would suddenly race with a fair chance of self destruction if you were too slow reacting.

Car rev limiters all trottle back the engine one way or another - this is the familiar "bounce" off the rev limiter, in a race car you will hear the engine hunting at max revs down the straights. With modern drive-by-wire engines it is possible to electronically restrain the actual throttle/fuel injection to achieve this but the simpler way is to briefly cut the spark creating a momentary misfire at max revs. In race cars most of the circuitry for this also exists to facilitate clutchless racing shifts.

Mechanical rev limiters (govenors) that used to be fitted to old diesels and even small engines like lawn mowers did it a different way using either centrifical force to lift weights that in turn limited the throttle opening or by air off a fan lifting a vane that did the same thing

Thilo might be confusing power with torque, by the time you get to the redline the torque is falling off so changing gear will bring the engine back into a higher torque band while not dropping the power much (the power curve is getting pretty flat up there in the stratosphere) - this might appear to be an increase in "power" ???

mmmmmm, i shall mull through these words, i get the difference. i only recall hitting the govenor in our '82 deisel vw camper. more than once. the only way to get up any significant grade was to red line it, especially loaded - it was geared like a truck, not a car. i never red lined the beemer, probably the fiat but i don't recall hitting the govenor. spirit is happiest reving high. i like to keep her happy! :beer:
