gearing for motovert rx

[brett26]

hi there, i just got a motovert rx with a 140 in it. my question is what gearing do i need to cruise at at about 80 ks?

its got a 17/37 sprocket (i think on it) and it does 80 but is reving high. i have a 35 rear to go on but i dont know if it will be enough.

We can all tell ya what we think but trial and error is the best way mate.

Try the 35 and see how it goes.

changed the gearing today, it was a 39 on the back.

it cruises ok at 80 now with the 17/35. i'm a big bloke (100kg) so i don't think it would push me if i went up in the front as well
