Yamaha TT-R 90 E weight overview
This is a genuinely light bike. That usually makes parking, pushing it around a garage and catching small low-speed balance errors easier than on larger motorcycles. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.
