hey everyone

just got a mc 21 frame droped of this moring. the rear tyre is huge! its a 160 is that standard coz i have a mc18 with the 5 spoke wheels and it only has a 140 on it. another question where do the lower fairings mount onto coz the mc16/18 have a little mount under the bike but i couldnt find any holes for one even, do they mount on the sides by stand and opposite. and finally does ayone know if i can run a mc16 motor on the 21 electrics.

thanks
