how fast 0-100?

[@ZTripleZ700]

Is this standard gearing? Have you done any other upgrades?

[@matijajurisa8171]

All parts are stock.

[@ZTripleZ700]

Ah nice

[@ZTripleZ700]

I was thinking of changing my rear sprocket to a 48 instead of a 49 to make it have a higher top speed but I dont know if it will pull it have you hit the rev limiter in top gear?

[@matijajurisa8171]

Downhill I can reach 135. If you put that sprocket you will have better top speed but you wil lose on acceleration.

mph or kmh?
