Yamaha TTR50

Introduced in 2006, the Yamaha TTR50 has been a popular bike for beginning riders. For a couple of years it was the only Japanese electric start entry level bike produced. Yamaha took a break and did not produce a 2010 and 2011 model year TTR50 (in the US, at least). While BBR has made a number of products for the TTR50 in the past, weak demand has resulted in discontinuation of many products. Everything we currently sell is listed on our website.
