MILAN, ITALY - BMW plans to offer 20 motorcycle models in 2008, ranging from the 50hp G 450 X to the 167hp K 1200 S. BMW calls the lineup the most diverse the company has ever offered.

New models revealed at EICMA included the G 450X, F 800 GS and HP2 Sport.

G 450X
As a completely new model for BMW, the G 450 X represents a clean-sheet design. The BMW-designed single-cylinder engine incorporates fuel-injection, electric start, a crankshaft-mounted clutch, liquid-cooling and the DOHC head borrowed from the K 1200 S. A 30-degree cant to the cylinder provides a straight, downdraft intake with an overhead airbox; the fuel tank resides under the seat with a filler at the rear, and the exhaust includes a three-way catalytic converter for compliance with all current emission standards.

The bike puts out 50hp and has a wet weight of close to 265 lbs.

The G 450 X chassis includes a fully adjustable Ohlins rear shock, Marzocchi "upside-down" fork and Brembo disc brakes front and rear. The compact frame mates stainless steel tubing with stainless forgings and an aluminum subframe and swingarm. A unique hollow transmission output shaft places both the countershaft chain sprocket and the swingarm pivot on the same axis. This coaxial design reduces the chain's effect on suspension response, smoothes power delivery, minimizes chain wear, and provides a longer (by 30mm) swingarm for more travel and better traction.

F 800 GS
The 85hp parallel-twin-powered F 800 GS is slotted between the F 650 GS and the R 1200 GS Boxer-twin.

Aside from its 800cc displacement, the only items this new model shares with the original R 80 G/S are the cylinder count and the final two letters. This new F Series GS borrows the 85hp counter-balanced parallel-twin from the F 800 S and ST, swapping their belt final drive for an O-ring chain in its transition to adventure-touring duties. But engine aside, the newest GS shares little else with its smooth-tired siblings. An all-new tubular-steel frame carries the F 800 well above terra firma, suspended between lightweight, 21-inch front and 17-inch rear wire-spoke wheels. The suspension consists of an upside-down fork at the front, paired with an aluminum twin-spar swingarm at the rear. A single shock with adjustable preload and rebound damping controls the rear suspension. Brembo discs-two in front, one in the rear-handle stopping, and the optional two-channel ABS can be shut off for serious off-road riding.

HP2 Sport
Loosely based on the R 1200 S, the 130hp HP2 Sport is the most powerful Boxer-twin yet, and the first production DOHC Boxer in BMW history. It's also the most track-oriented production Boxer-twin ever to come from the firm.

Don't believe it? Need coaxing?

Aside from the powerful engine, the HP 2 is further designed for competition with a gear shift assistant that allows a rider to bang through the six-speed gearbox without using the clutch lever. It's decorated in carbon fiber bodywork, and has fully adjustable Ohlins shocks, Brembo four-pot calipers, and adjustable handlebars, footrests and Magura brake levers. Oh, and the instruments come directly from MotoGP — with digital readouts, lap timer and a tachometer with graphic rev display. (Continued)
