Triumph Speed Triple S

; it was switched to a regular handbar To 2004, the Nissin brakes were problematic. Although the 955i was initially praised as one of the best stopping bikes, many owners complained of brake sponginess. But its capacity was increased to 1,050 cc by lengthening the stroke. It was also fitted with a fuel injection and engine management system made by the Keihin Corporation.

To improve rider comfort and low speed handling. When the T509 Speed Triple had an 885 cc fuel injected engine, the Daytona received an upgraded 955 cc engine that produced 130 hp (97 kW) at the crank.

The new Speed Triple was officially upgraded to 955 cc status and received the bigger engine. The engine was very similar to the unit found in the Sprint ST, but the motorcycle did not feature Nikasil lined cylinders.

And 2001, the Speed Triple did not change much beyond appearance; the engine control unit was updated to the Sagem MC2000. The 1997–99 bikes had a ground block known to fail, so the 2000 and 2001 bikes received an improved wiring harness.

Gareth Davies redesigned the bodywork. The 432 lb (196 kg) was reduced by a change to the engine casings of the 955i engine that decreased weight by roughly 17 pounds.

Triumph released its fourth-generation Speed Triple. The engine was still the same one used

Several changes were made to the bodywork, and Italian-made Brembo front brakes were supplied as standard. The new Speed Triple shared its engine with the new Sprint ST and later the 2007 Triumph Tiger 1050.

With a limited-edition model that featured black paint with red trim and a number of optional accessories that were added as standard equipment. The bike was also the first production Triumph to feature the signature of company owner John Bloor.
