QR Code Link to This Post This is a youth size enduro sized motorcycle. I purchased this unit for my son a few years ago, but it is now time for him to get a bigger bike (kids keep growing). This motorcycle has been well maintained, and runs great. below are the basic specs. The semi automatic transmission is great for young riders and allows them to focus on the basics without having to master the clutch early on. Featuring a semi-automatic gearbox for clutch-free gear changes, the TT-R90 is suitable for children who may have outgrown our smaller 50cc bikes - and like all of our junior models the TT-R90 comes with off road tyres and stylish YZ-style bodywork.General information Model: Yamaha TT-R 90 Year: 2007 Category: Enduro / offroad Rating: 76.9 out of 100.
