Wow! Look what Yoshimura has done to the GSX-R1000
Yoshimura’s new Tornado S-1 is based around the MCN Award-winning Suzuki GSX-R1000 but little of the original remains untouched.
The engine’s compression has been raised from 12.0:1 to 13.2:1 by re-grinding the head and fitting a slimmer head gasket. The stock camshafts and valve springs have also been replaced with higher-grade Yoshi items, allowing the engine to rev 500rpm higher to 12,700.
The stock Suzuki EMS – engine management system – has been replaced with a new Yoshimura black box. It comes with a handlebar mounted three-way switch that allows the rider to switch between three different power maps, while on the move.
The exhaust is a 4-1 titanium Tri-Oval system and the engine has been lightened by the fitting of Yoshimura cases and sump – which has also increased the oil capacity 300cc. The gearbox is now fitted with a quick-shifter and sensors for a dash-mounted shift light.
All this work has resulted in 168bhp and 80ft/lb at the back wheel – compared to around 148bhp and 78ft/lb of the bike they started with. The power has been moved up the range 1200rpm though, with peak power at a staggering 12,000rpm.
The entire machine is suspended with only the finest Öhlins components. Fitted to the front end are modified Nissin 6-pots and a Nissin Radial pump master cylinder on the Yoshimura clip-ons. The brake discs remain unchanged.
The lightweight wheels should further improve the GSX-R’s already quick steering. They’re aluminium and manufactured by BBS.
Yoshimura has developed a new carbon-fibre body-kit for the machine.
Only 50 are to be built and they are expected to cost of over £23,000 each – excluding shipping! If you are interested, call 01782-569814.
More on this in MCN on November 21.
