frankly it seems its like pulling a number out a barrel whether you get a bike that lasts or doesnt with ANY cheap pitbike. Ive heard good and bad from most brands. But from myself and 2 other mates with pitpros, weve all rode them hard, BUT also constantly maintaining them, theyve handled everything fine..
Or you can go out and spend over 2k on one and whinge at the guys that dont.
