After several teaser images of the Suzuki’s new contender for the middleweight sportbike-derived naked bike market, the Japanese motorcycle manufacturer finally revealed some technical details and official photos of the 2011 GSR750 model.

While the photos speak for themselves in terms of styling, when it comes to technicalities, Suzuki decided to get straight to the point.

Powering the 2011 GRS750 is a liquid-cooled, four-cylinder DOHC four-stroke engine with a bore and stroke of 72 mm x 46 mm and four valves per cylinder. The valves are set at a very narrow included angle, allowing the combustion chamber to be very compact, with the intake valves each measuring 27.2 mm in diameter and the exhaust valves measuring 22 mm in diameter.

The compression ratio is 12.3:1, with lightweight cast aluminum-alloy pistons. Those details improve combustion efficiency, and more complete combustion is the key to better low-rpm and mid-range response, acceleration and fuel mileage, as well as reduced emissions. The engine powers an integrated close-ratio six-speed transmission.

Moving on to the chassis, Suzuki says it incorporates the best qualities of a compact tubular girder streetbike frame and a twin-spar sportbike frame, and is built using a combination of D-section and round-section steel tubes for an especially smooth ride. Wheelbase is 1,450 mm with 25°15' of rake and 102  mm of trail, again contributing to a comfortable ride.

The GSR750 features lightweight three-spoke cast aluminum wheels. The front wheel carries two 310 mm fully-floating brake discs, with Tokico hydraulic dual-piston calipers. The rear wheel is fitted with a single 240 mm brake disc and a Nissin single-piston caliper.

An optional Antilock Brake System (ABS) will also be available, with a new, more compact control unit.
