Hayabusa headlines USA launch

Suzuki will, on Monday 2 July, show its USA dealers several new bikes for 2008, including the much-awaited revamp of the Hayabusa.

Included will be three variations on the 1800 cruiser platform, including a tourer.

There will also be new range of motocross machines.

However the Hayabusa update has so far been the most closely-held secret - detail has finally emerged only a few days before the unveiling.

The company has kept a lot of the original Hayabusa styling cues, but has updated the swoopy lines with influences from the current GSX-R range.

Still a four-cylinder, the engine has been bumped up in capacity to 1340cc, and has had a lift in compression to 12.5:1 (from 11.5:1) and now claims just on 200 horsepower and 15kg-m of torque. Like the current GSX-R1000, it has three selectable engine modes available from its ECU.

The chassis has also come on for a major upgrade, with much-modified frame and swingarm, plus four-piston radial-mount brakes instead of the old six-spotters.

It has lost about 5 kilos (down to 220) and, so far, no top speed is mentioned, though we suspect it will be speed limited to just under 300, like the old model.

See below for Suzuki's full list of alterations.

Full list of changes -- Suzuki:
Redesigned instrument cluster now features four analog meters for speedometer, tachometer, fuel gauge and water temperature with a new S-DMS mode indicator, gear position indicator and adjustable engine rpm indicator.
