After the first initial sketch and several teaser images of the Suzuki’s newest contender for the middleweight sportbike- derived naked bike market, the manufacturer has finally revealed the first official photos and technical details of the 2011 Suzuki GSR750. Powering the new GSR750, is a liquid- cooled, four cylinder DOHC four- stroke engine with a bore and stroke of 72mm x 46mm and four valves per cylinder. The valves are set at a very narrow angle, making the combustion chamber compact, with the intake valves each measuring 27.2 mm in diameter and the exhaust valves measuring 22 mm in diameter. Combustion efficiency is optimized, owing to the compression ratio of 12.3:1, with lightweight cast aluminum- alloy pistons. The engine powers an integrated close- ratio six- speed transmission.
The chassis on the new GSR750 incorporates a compact tubular girder streetbike frame and a twin- spar sportbike frame, and is built using a combustion of D- section and round- section steel tubes for an especially smooth ride. The bike stands on a lightweight three- spoke cast aluminum wheels, with a wheelbase of 1,450 mm. Two 310mm fully- floating brake discs, with Tokico hydraulic dual- piston calipers are carried on the front wheel, while the rear wheel is fitted with a single 240mm disc brake and a Nissin single- piston caliper.
