apart from the odd sticker or colours, are there any mechanical differences between the 2000 and 2004 model STs? i want a haynes manual for mine but they only list years up to 2000.

keep it pinned guys. or gals. or some of those strange types you see in Brighton

Dave,

'99 - '01 are the same (except for colors) and '02 - '04 are the same (ditto). Significant differences in engine configuration occurred with the '02.

Keep an eye out for the Factory manual. They sometimes pop up on eBay.

Here's a write-up of the changes from an on-line brochure. The frame and hardware are pretty much unchanged.

-------------------

The engine changes offer even more of the long-legged performance the Sprint ST is renowned for. The new 120bhp powerplant is identical to the new 955cc three-cylinder engine fitted to the new Speed Triple and Sprint RS. Employing high-pressure die-cast crankcases for both strength and lightness, the DOHC 12-valve liquid-cooled engine's new cylinder head utilizes 1mm larger inlet valves and 1mm smaller exhaust valves, set at a narrower included angle. Both inlet and exhaust ports are redesigned for better gas flow and the new cast pistons run in steel liners. Compression ratio is up from 11.2:1 to 12:1.while crankcase breathing is revised to minimise power loss. The new engine is 2.5kg lighter than before.

A larger airbox feeds the new closed loop fuel injection system which features smaller, lighter injectors, while compact, light plug-top ignition coils provide dependable high-intensity sparks. The closed-loop system features an oxygen sensor that monitors and adjusts the air:fuel ratio at varying engine speeds to optimise engine performance. The fuel injection mapping is tuned for even more mid-range torque making the Sprint ST's punchy three-cylinder performance even easier to use to the full.

As on the Speed Triple engine, the alternator is now located on the left-hand end of the crankshaft and the starter motor drive is located on the right. This layout, reduces noise, especially at idle, as there's now no need for a gear-train to drive the alternator. And a revised claw-type gear-change mechanism gives a much smoother and more positive shift action.

The exhaust system has new headers and balance-pipe to further boost midrange output and for the German and Californian markets a secondary air injection system is fitted to minimise emissions. Cooling and lubrication systems are revised with the coolant radiator featuring a thinner core, increasing efficiency without adding size or weight. The Sprint ST is available in distinctive British Racing Green, cool Sapphire Blue and dashing Tornado Red

I like the part about the Tornado red being "Dashing" :-D

thanks guys, i wont bother then with the haynes book.

incidently, the green ST(like mine) is called ASTON GREEN officially, i heard triumph couldnt call it BRG because the name is copyrighted and owned by someone else who refuses to let others use it, like bentley or someone. i call it BRG, so up yours whoever you are. :hammer:

hmm, not sure the Trumpy Aston green is the same colour as BRG.

davsato · 08-20-2005

its not Ern, its metallic and BRG is "greener" if you know what i mean.

Is it the numbers that are different, I'm a bit slow?

davem :-D
