Re: Suzuki skydrive 125 electric conversion

I’m not surprised that direct drive is better than CVT in your application, ... belt driven types like used on scooters. The Comet Torq-A-Verter is one and there are some with significantly higher power ...

Re: Torq-A-Verter CVT

macribs, my reply was about the CVT linked to in the original post, the $100-180 GTC/COMET/Clone CVTs for minibikes and go karts. My setup was 8:1, 26". One day my driver unit exploded 3mi from home because I didn't use a ...

Re: Torq-A-Verter CVT

These CVTs are the evil in the world of low-powered bikes, IMO. Although they say they are good for 3-8hp, they really aren't good under 5hp at the very least. There are a few problems in play here:....... There are so many choices ...

Re: Torq-A-Verter CVT

Again these are less than 750 lbs which was the point that they don't work well in larger machines. It's easy to run higher power with less weight or visa versa......less power and more weight. Tom Well today I saw a monster ...

Re: Torq-A-Verter CVT

Hm. Today there are Ski-doo's, Yahama's, Arctic Cat's and other sleds that run 1 liter engines with turbo and 300-350 hp. I know of a couple of Yamaha's that are pushing between 240 hp and up to 320 horsepower and they seems ...

Re: Torq-A-Verter CVT

While I've never used one on a electric motor I have used CVT's extensively in high powered off road cars. Starting with the Honda FL350 Oddessy, Honda Pilot and Drakart Formula Cross. Stock clutches, Comet Clutches, Power Bloc and many ...

Re: Torq-A-Verter CVT

Hm. Cable operated clutch and plastic lever? Can it handle torque from an electric motor? If you really need a gearbox why not check for lightweight racing CVT's for tuned up scooters, or go carts? Those are simple mechanically, ...

Re: Torq-A-Verter CVT

Thanks for sharing that bike macribs. Id never seen it before.
I like it. To bad about the price, but such are luxury toys.
Kool that it's made in Montreal. Not too far from me.
Something that I can register here in Canada should I win the lotto. :mrgreen:

Re: LandRider Autoshift

I think the weights need to be smaller, not bigger. If there are springs involved, then stiffer springs may help do what you want. I tuned my Comet Torq-a-verter CVT to better match an electric motor by changing the springs. I didn't fool with the weights.

Re: Torq-A-Verter CVT

The same thing can be accomplished with a variator system from a scooter or moped. The parts from a Motobecane or puegeot 103 would likely be the best. Both require a pivoting motor mount. Another method would be parts from ...
