Looking into purchasing a set a of Performance machine wheels for my Street Bob and was wondering if you guys could help me make my mind up on rim size. Obviously im currently running the stock 19" front rim but the performance machine rim comes in a 21". Would i lose any handling upgrading from a 19" front to a 21"?

So what ur sayin that the extra weight of the rim makes it harder to brake??

The cvo Dyna has a 21 inch with no probs, they wouldn't make a wheel that couldn't handle the weight.

 The 21 won't handle as good as the stock 19. Your braking will suffer a little due to a smaller "footprint" of rubber on the road.(21s are a lot skinnier!)

The 21 will tend to track easier along road imperfections. Your speedo will need adjusting to suit the new size and no doubt you will need to modify existing or buy a new front mud guard.

Burto.

Thanks for the input guys findin it really helpful..

Yeah you'll be traveling faster than you realy are.
