Variators

[Jwestie15]

Has anyone ever fitted variator to the 2stroke HT? Most of the race ped gp type bikes have variators and they are damned fast

What's a "variator"?

I have a nuvinci hub which is a lot like a variator as an end result but never seen that on any happy time motor or even 4 strokes for bikes..

There aren't any real automatic transmissions for these kits, everyone is fine with manual here for the most part. I would say if you are especially crafty you could Jerry rig something to together but nothing right now you can buy as an add on variator.

Socal Motor Bicycle Racing does not allow shifting motorcycle engines but you could always shift gears using the rear hub like the Sick Bike Parts kits.
We allow CVT's too.

Yes a variator is a cvt

I believe he means a rear wheel cvt, such as a nuvinci hub, which is a form of a cvt, they really don't want the transmission comming off the side of the motor shifting should be from the bars. Hence the word bicycle in the title.

NO a variator is a belt drive cvt system used on pedal mopeds puegeot motobecane mobylette. They can be tuned with weights and fitted with launch levers they are pretty trick
