I am very disappointed with my XC200. After 4 months of racing, my tires are bald! What kind of crap is that?!
Seriously, my plastic will be shot by next season, the fuel filter broke apart, I lost a chain roller, I am replacing the rub plates and chain roller on the chain guide, broke the kickstand mount, and slightly tweaked my front rotor. The left radiator even survived being bent back about 4 inches and subsequently being straigtened with my foot!
My fork tubes also came in contact with the frame rails (should have checked those steering stops more carefully) and put a small dimple in the frame. Amazingly, the fork tubes survived unscathed.
In addition, the stock heavy duty tubes have survived 3 tire changes and my air filter door has never popped open.
All in all, the bike has proven to be very reliable and the replacement parts I have needed have always been in stock (thank you Smackover!).
