The Yamaha TT-R225 is a trail bike that Yamaha produced from 1999-2004. The following year after they ceased production of the TTR225 they replaced the out going model with the TTR230. TTR225's are known for being extremely reliable. The TTR225 is nearly identical to its street legal sister bike, the XT 225, the only difference being the lights, passenger foot pegs, smaller rear sprocket, and other street legal accessories. The names TT, TTR, and XT have been used for off-road and dual-sport versions in different markets and in different eras. Counter-intuitively, the TTR has chromed steel wheels, steel engine guard, and lower seat height than the lighter XT with its slimmer body and alloy components.
