2021 Yamaha TT-R125LE [Model Overview]

2021 Yamaha TT-R125LE

The 2021 Yamaha TT-R125LE is the Perfect Trail Bike

The 2021 Yamaha TT-R125LE is a bike that is positioned perfectly in the trail bike lineup to offer the teenage rider trail riding excitement, while also helping them learn how to handle off-road terrain. Geared more towards a younger audience, this Yamaha bike moves to a manual transmission and has bigger, grippier tires to get things moving. It is also a suitable trail bike for lighter, smaller adults looking to learn how to trail ride.

Powered by strong Japanese engineering, the TT-R125E is powered by an air-cooled, 125cc, 2 valve 4-stroke engine that is linear and delivers a lot of its torque in the mid-range, where you need it for hills and obstacles. Torque is rated at 7.3 lb-ft, although like most trail bikes, horsepower figures are not available.

Another shift up from the junior bikes is the addition of a disc brake at the front with a twin-piston caliper to control the faster speeds that the TT-R125LE can reach. The rear remains a drum brake.

The 2021 Yamaha TT-R125E starts at $3,349 USD / $4,299 CAD.
