besides the plastic everything is perfect. it drives and runs great. i have only had the bike since november. tune up was done right before i got the bike, and oil was changed last month. tires are ok but need to be changed sometime in the near future.. i hit a patch of gravel from construction. i went right down on its side. the frame slide saved alot of damage. the bike slowed to a stop without hitting anything. this was at about 30mph.
