Dirt Bike FAQ

This is "bicycling" but I'll have a go at answering;
there's not very much difference between 80 and 85 cc.

I would guess 75 MPH, but it has a lot to do with how much you weigh, and if there is an uphill.

I hope you are going to take good care of the bike, and not blow the gaskets inside the first week you own it.

There are Electric Bikes, as an alternative,

I've seen people interested in buying bikes, who see the electric bikes, and aren't interested because the e-bike doesn't make noise and smoke.

As I said , this is bicycling, which is a completely silent way of traveling.
