Yamaha's off-road family continues to produce more offspring. In 1999, Yamaha introduced the all-new electric-start four-stroke TT-R225 and TT-R250. For 2000, Yamaha introduces three all-new motorcycles, the TT-R90, TT-R125 and TT-R125L.

The 2000 line of Yamaha off-road bikes, eight models total, has machines not only for the adults, but beginners and kids' bikes, as well.

THE 2000 TT-R90 (NEW FOR 2000)

During the 1980s and 90s, Yamaha firmly established itself as the leading producer of children's bikes - thanks to models like the PW80, PW50, and RT100.

A four-stroke SOHC 89cc air-cooled engine powers the new TT-R90. This compact and reliable powerplant has been specially developed for the TT-R90, and is equipped with a lightweight crank and compact CDI rotor, that ensure instant throttle response and spirited acceleration. A Mikuni VM16SH carburetor delivers a precisely-metered flow of fuel to the low-emission 89cc engine.

The new TT-R90 features a 3-speed, semi-automatic transmission, that allows riders to develop their shifting (i.e. riders graduating from the fully-automatic PW50) and throttle control skills without having to worry about a clutch.

The TT-R90 chassis is based on the highly successful PW80 design, while its radical new bodywork has been inspired by Yamaha's championship YZ line. Its tubular twin-spar construction makes for a rigid chassis, and this design also offers plenty of access to the engine for easy routine maintenance. For added engine protection, the TT-R90 is fitted with a tough steel engine guard. A grab handle behind the seat makes for easy loading into a van or trailer.

Long travel front forks give a generous 4.3" of smooth-action wheel travel for a soft ride, while the lightweight Monocross rear suspension features a Bilstein-type shock absorber, operated by a square-section swinging arm and offers 3.7" of travel. Equipped with a 14 inch front wheel, 12 inch rear wheel and a low 24.5" racing-type seat, the TT-R90 is ideal for most children.

A lightweight plastic fuel tank with air scoops, YZ-type front and rear fenders, sidepanels, front number plate and bright new graphics make the TT-R90 one of the most impressive looking children's bikes around today.

The 2000 TT-R90 is available in Team Yamaha Blue/White for a manufacturer's suggested retail price of $1,649.
