Triumph Thunderbird Sport Specifications

The Triumph Thunderbird Sport

Triumph Press Release January 2000

The Thunderbird Sport promises a great deal with its classic flat track styling emphasized by its striking color options and finished to perfection with its pair of reverse cone silencers stacked one above the other on the right-hand side.

It lives up to that promise thanks to a chassis which has been described by many testers as the best handling of a Hinckley Triumph aside from the Supersport T500 series.

Compared with the Thunderbird from which the Sport is derived, the suspension has a longer travel.

The wheels front and rear are a sportier 17 inch diameter (compared with 18 and 16 inches front and rear).

And the front brake is uprated to twin disc specification from single disc.

In addition, to help riders take advantage of the enhanced ability of the cycle parts, the engine is upgraded over the Thunderbird.

It produces 83PS (82bhp) and 76Nm (56lb.ft) compared with 70PS (69bhp) and 72Nm (53lb.ft).

The result is a classically styled machine in authentic Triumph tradition with the ability to perform very much as modern riders expect and enjoy.

New Features for 1999

1. Longer side stand to hold the bike in a more upright stance and make it easier to lift the bike into the fully upright position when starting off.
2. Shorter, color matched mudguards, for improved looks.
