Dad is seriosly thinking of buying a 110 thumpstar on Monday and wants to know before buying if he can put big wheels on it? I think you can but he wants to be sure.
front mightnt have a problem depends bigger size may mean it will hit the engine or bash plate, but if it has a small a frame on it than max 12'' at the rear
I don't know weather the frames are the same as the 110's and the thumpy PRO but on my bike i run a 12/12 wheel setup. I am not to sure if a 14 would fit. When you're just ask the bloke and he might know. Cheers.
