When Triumph launched the TT600 into the most competitive sector of the market in 2000, it had high hopes for the all-new dohc in-line four. But although the handling was superb and the brakes brilliant, the fuel injected motor suffered from flat-spots at low revs. Triumph tried to cure the problem by re-mapping the computer, but never completely cured the problem.
Now Triumph has updated the TT600 for 2002 with a fuel injection system that seems to have sorted it out at last. You also get new colours and graphics. The TT600 is now a fast, supremely agile machine that is equally at home on road or track. Its 16-valve, liquid-cooled four-cylinder engine produces a competitive 110PS (108bhp) with impressive midrange torque for a middleweight.
On its introduction the six-speed TT600's sophisticated fuel-injection system was a first for the class. The latest refinements to the Sagem MC1000 electronic engine management system, which has automatic cold start compensation and self-diagnostic capability, have optimised response right across the rev range.
Chassis design is based around a hugely rigid twin-spar aluminium frame, which holds top quality suspension. Front forks are Kayaba 43mm cartridge units with adjustable spring preload, compression and rebound damping. The Kayaba rising rate monoshock rear suspension is adjustable spring preload, compression and rebound damping.
The result is a bike that has won praise for its stunning blend of quick-steering agility and remarkable high-speed stability. Specially designed, ultra-lightweight cast aluminium wheels also contribute to outstanding cornering ability, while twin front disc brakes and four-piston calipers lifted from the Daytona 955i provide fierce yet supremely controllable stopping power.
Top speed from the TT600 is a touch over 140mph. If only Triumph could do something about the bland styling it could be a contender.
