Hi im looking to buy a new bike im 5'5 and 115 pounds and have lots of experience on dirtbikes and want something that is fast and lightweight. I am looking at a cr125 but they only have 5 gears and the rm and yz have 6 so would the cr have trouble keeping up with these bikes or can it deliver enough power in only 5 gears?
Even with 5 speeds, that
Even with 5 speeds, that really has nothing to do with keeping up with those other bikes. If you ride in the woods, you may shift a bit more, but there is nothing that gearing can't take care of.
