TRIUMPHTT600 2003

　　The Triumph TT600 was a middleweight sports machine introduced in 2000 and manufactured until 2003, when it was replaced by the Triumph Daytona 600. The bike was designed to enter the 600cc market shortly after the company returned to the American market.

　　The Triumph TT600 was their first inline four-cylinder fuel-injected motorcycle developed to compete in the most competitive fuel-injected middleweight category. The bike was known for its handling and braking performance, being known in the industry as well-balanced.

　　Unfortunately, the first fuel-injected 2000 Triumph TT600 machine had two major issues, including choppy throttle response and bad fuel mapping, making the throttle transition go on and off.

　　The company addressed the problems with the introduction of the 2001 Triumph TT600, but some of the machines ended up with two to three horsepower less in the upper section of the powerband.

　　The 2002 model added back the missing small amount of power with more Electronic Control Unit (ECU) programming, ensuring that the machine delivered enough ability to compete with its rivals.

　　In 2003, the English motorcycle manufacturer launched the Triumph TT600, the fourth and last model in the series that benefited from the previous engine and fuel injection modifications, achieving new performance levels.

　　The 2003 Triumph TT600 had installed underneath its full fairing a 599cc four-stroke liquid-cooled four-cylinder engine with a revised fuel injection system, boasting 110 hp with maximum strength at 12,750 rpm and 68 Nm (50 lb-ft) torque at 11,000 rpm.
