it would have to be the Yamaha ttr 90
A TTR 125L is what I bought my daughter to learn to ride on. Very dependable and mild mannered, a good bike to learn on.
I know someone who recently got a Yamaha ttr 90 on e-bay.
50-55
Yamaha TTR 125
The precise type of oil that a Yamaha TTR 90 dirt bike should use can depend on the year the bike had been manufactured ad should be listed in the manual for the bike. For a 2002 Yamaha TTR 90 bike, the recommended oil type is 10W-30 (when 10 degrees Fahrenheit or above) and 20W-40 (when 40 degrees Fahrenheit or above).
Probably a yamaha ttr 110
Not very loud, a race bike is much louder
