TRIUMPH Thunderbird Sport (1998-1999) Specs, Performance & Photos

In 1998, the British motorcycle manufacturer launched the Triumph Thunderbird Sport, a more sporty model than the standard version. In addition to the standard and Sport models, the maker made the Triumph T309TT Legend and the Triumph T309RC Adventurer available.

Compared to the base model, the Thunderbird Sport came with different wheels, an additional brake disc on the front, fully adjustable front and rear suspensions, and a boost to the engine from 62 to 82 hp.

Also, the aesthetic department was improved with a blacked-out engine instead of chrome, a redesigned exhaust system with two mufflers mounted on the right side, and the stitching and buttons were removed.

Besides that, the bike packed standard features, such as a round headlight with instruments mounted on top, a one-piece dual seat, a side stand, and lightweight wire-spoke wheels.

In the suspension department, the bike packed a 43 mm fully adjustable telescopic fork on the front and a fully adjustable shock absorber on the rear, delivering excellent suspension performance and handling.

The braking power was handled by two 320 mm discs with two-piston calipers on the front wheel and a 285 mm disc with a dual-piston caliper on the rear wheel.

As for the power figures, the 1998 Triumph Thunderbird Sport had installed an 885cc four-stroke three-cylinder liquid-cooled engine that delivered an output power of 82 hp at 8,000 rpm and 72 Nm (53 lb-ft) torque at 4,800 rpm.
