The twinshock YZ125B is a carry over. Make sure it's a 5 speed.

Joh n I have a rickman zundapp frame, having probs getting "good parts" for Zundapp so was thinking of either an MX-a, YZ-a or YZ-b motor, if i can find one.

Like to have a go at the Zundapp retso .  Would you interested in a Swap for a 125cc Husky to match the 250cc  :)

Cheers
