The most I've seen so far is this cut & paste from the Triumph Marketing guys:
"The main changes are:
Long-stroke 1050cc motor from the new Sprint ST, tuned for 128bhp
78ftlb of torque – more than a Yamaha R1
Upside-down forks
Superbike-style radial front brake calipers
Radical styling, including ultra-short seat unit and new fuel tank
Stylish new instrument panel
New single-sided swingarm
Lightweight five-spoke wheels
Twin high-level exhausts
Triumph’s product manager Ross Clifford said: “The Speed Triple is one of our strongest-selling models. It’s an iconic bike, and we want to build on that.
“We wanted a masculine, aggressive look, giving more from the engine and the styling.
“We wanted to combine the masculinity of the ’94 bike, with iconic styling, such as the frame and twin lights from the second generation. And we wanted to make it a really strong riders’ bike.”
Styling: The 2005 Speed Triple has a pure streetfighter look – reflecting the sort of aftermarket changes many owners would make. Triumph has saved them the bother...
Clifford said: “For the styling we looked to some of the specials that have been based on the Speed Triple. We wanted that feel for the production bike, with minimal bodywork and a powerful engine, plus top-spec chassis components. The bike’s minimalist bodywork accentuates the feeling of riding a small bike with a powerful engine.”
Engine: The new bike gets a reworked version of the new1050cc Sprint ST motor, with 128bhp and a huge 78ftlb of torque. But that’s not the whole story.
Clifford said: “The new engine is just phenomenal. There’s 25 per cent more torque at 3500rpm than the old one, and at 3400rpm it makes the same as the old Speed Triple did at 6000rpm. It also gets the same refinements as the new Sprint ST, with a shorter-action throttle and a backlash gear on the clutch to reduce vibrations.
“The new exhaust with two really short cans gives a much deeper tone than the current bike.”
Chassis: While the frame is the same as the current Speed Triple, the suspension and brakes are a step forward.
Clifford said: “We’ve really specced-up the chassis. The Showa forks are fully adjustable, and we did a lot of work on the Nissin radial calipers before we were satisfied with them – we didn’t originally feel they were as good as our current set-up, which is already very strong.
“There’s a 180-section rear tyre instead of a 190, which improves the steering, and new five-spoke wheels, which work really well with the styling of the Speed Triple.”
Instruments: From the rider’s seat the Speed Triple still looks great thanks to completely new clocks.
Clifford said: “The new instruments are very high spec. The digital display offers all the functions you need, like average and maximum speeds, journey time, a clock... and there are programmable gearshift lights, which can be set by the rider.”
I've had my deposit down for 2 months now, and although I'd love to see a test soon, I'm still banking on good things from this bike.
I foresee nice quick steering, 1 finger front brakes, and with that type of torque signature

1st & 2nd throttle mingers easy and 3rd with a wee bump and a good twist. No clutch needed.
