Big bikes big for BMW

First is the R1200GS Adventure with a 33-litre tank next month, followed by the R1200S, with 25 per cent more power, and the K1200GT in June.

BMW national marketing manager Cameron Cuthill has just returned from the world launch in South Africa of the F800S and ST midweight sports bikes, which he says will be here around August.

Cuthill said prices were not yet decided.

The bikes, which fill the gap between the 650cc and 1200cc models, feature BMW's first parallel-twin engine, a new suspension system and quiet, low-maintenance, long-life belt drive.

The 798cc four-valve liquid-cooled DOHC engine delivers 63kW of power and 83Nm of torque and is available in the half-faired F800 S and the sports touring orientated F800 ST, both with a close-ratio six-speed gearbox.

The engine was developed by BMW in close co-operation with Austrian manufacturer Bombardier-Rotax and is built in the Rotax plant.

The F800 has an aluminium frame, single-sided swing-arm, a stainless steel exhaust system and conventional telescopic forks which BMW says help to keep weight down to 182kg dry for the S and 187kg for the ST.

The 16-litre fuel tank is under the seat for a low centre of gravity and with easily accessible filler manifold, similar to the single-cylinder 650cc machines.

Riders won't have to remove their tank bag to fill up.

Both models will be available from the factory with BMW's new, optional two-channel anti-lock braking system.

Braking is provided by twin 320mm discs with four-piston calipers and sintered metal pads up front and a 265mm single disc and single-piston floating calliper on the rear.

The F800 S comes with the same cast aluminium wheel design as the K1200 S, while the F800 ST features the R1200 ST wheels, all with side-mounted valves for convenient tyre pressure control.

An electronic immobiliser is standard.

The mirrors come with a special rest position enabling the rider to quickly find the perfect setting after folding them back.

The F800 S comes in "sunset" non-metallic or "flame red" non-metallic, while the F800 ST comes in blue metallic or "graphitane" metallic.

It should have special appeal for shorter riders and women with a seat height of 820mm, or 790mm option and slender seat waistline.

Other options include various items of luggage, heated handlebar grips, on-board trip computer, centre stand and an anti-theft alarm system.
