Can any one provide measurements for the rear end of a B2 Alloy Framed minimoto.

The rear end is all cocked up - the rear wheel looks like it is about 2 inches offset to the left. However, if I move it by changing the spacers, I think it will bind on the brake caliper.

What is happening when I ride it , is it wants to pull towards the right, turn or lean left and it almost wants to kick you off.

The only thing I can think off is that the rear wheel is back to front, and I would need to change the sprocket and disc around, is the offset the same, or are they different?

I am so much wishing I had bought a new one now....

Will measure mine tonight for you Ray.
You can swap the sprocket and rotor as the threads are the same but you obviously need the chain running straight;)

Hi Ray,
My B1 wheels are the same as B2s and have an equal offset on each side, around 55mm from spokes. Even the spacers are the same around 20mms.
The swing arm is not central though, off to the left slightly.
I know the brakes on the later B1 & 2s have a tendency to bind and are hard to set up as they rely on the piston pushing from one side and rub on the caliper.
Plus they have very little float.
Hope this helps.

Hey Alan, yeah, I think that was my issue - the swing arm is NOT CENTRAL as you say. I ended up with 12mm more gap on the right side that was central s unavoidable. Seems ok now, had to create a small spacer.
