Yamaha TTR125
The TTR125 was introduced in 2000. The TTR was an immediate hit. At the time the TTR125 was introduced the XR100s were the king of the play bikes. The TTR came on the scene and had a disc front brake, better suspension, and more power. It was a home run. The tracks turned from red to blue over night. The TTR is a great trail bike and is also perfect for your wife or girlfriend to get involved in the sport. The TTR is super easy to start (once you get it jetted properly) or you can get the LE model and just hit the magic electric start button. The LE also has an aluminum swingarm and adjustable shock. The TTR125 received all new bodywork in 2008. The best part of the TTR125 is that it handles like it is on rails. This bike will turn anywhere. Inside - outside it doesn’t matter. The must have items for the TTR are the chain guide, Free Flow air filter, exhaust system, heavy duty springs, and cradle. BBR makes just about every trick part for the TTR so let us know how we can help.
