2012 Suzuki GSX-R1000

Suzuki’s 2012 GSX-R1000 gets the same package of upgrades as the GSX-R600, which have already propelled the supersport machine to the top of its class.

While the styling is unchanged, a range of updates has been made beneath the skin which could transform the bike, which lost the British Superbike Championship by 0.006secs!

The headline changes include the fitting of Brembo Monobloc radial front calipers along with Showa Big Piston Forks, a combination which has given the GSX-R600 the best front end in the class. At the same time the disc thickness is reduced 0.5mm to 5.0mm for reduced weight. The front axle and tyre are also lighter than before, adding up to a useful reduction in unsprung mass.

The BPF forks are softer than the previous equipment with slightly less travel, made possible by the improved damping control, which should improve both grip and stability, especially under braking. The rear Showa shock is unchanged, as is the bike’s electronically controlled steering damper, which adjusts automatically according to speed.

The 999cc engine’s changes have quickened throttle response as well as increasing power and in particular mid-range acceleration, according to Suzuki, as well as improving economy by eight per cent. New pistons are used which are 11 per cent lighter, with changes to their shape to improve combustion efficiency. The compression ratio is up slightly to 12.9:1.

Revisions to the ventilation holes between the cylinders have reduced pumping losses and reduced crankcase weight, while the valve buckets are reshaped to reduce mass and allow faster valve lift. This has allowed Suzuki to reduce valve overlap and boost low and mid-range torque without compromising high rev power.

The previous twin silencer exhaust has been replaced by a four-into-two-into-one system, with pipes made from thinner stainless steel than before to reduce weight and a titanium silencer. It’s this which is responsible for most of the bike’s 4.4lb (2.0kg) overall weight reduction. The engine management has been revised to suit the changes and refine the power delivery.

Most of the styling changes are due to the mechanical changes, such as the BPF forks, Brembo brakes and new exhaust system, although the wheels will feature red pinstripes and ‘R’ logos, the GSX-R graphics are larger and there’s a new LED rear lamp. The rev counter has a new black face.

The 2012 GSX-R1000 will be in Australia sometime during the first half of 2012, with pricing still to be announced.
