15 x 48 or 50
With the 6 speed the gearing listed can just about do anything you need including moto.
My bike is used in Worcs,Desert,GPs,Moto and even some Enduro with that gearing.
If they have the e-start and 6 speed you have a bike that has more power than anybody else on the track. Just hit the weights as this bike can tire you a little more than a 450.
You can even get a small or large tank now if you want to? You need to get back to us after you get it set up and tell us how you like it. We have money on it that you are going to say the same things we do.
This bike is developing a cult following like the people that have KTM 300s it seems.
I have one of those also so it is covered at my house!
You will love this bike after you get 10 or so hours on it as it gets much faster after that.
