GSX-R1000 Motorcycle

New 999cc four-cyclinder powerplant is modified to deliver extraordinary acceleration matched by maximum top-end performance of world-class racetrack performance.

Race-proven designs include high-quality titanium valves, forged pistons, shot-peened conrods and large intake and exhaust valves.

Pentagonal cut-outs in the sides of each cylinder bore have been enlarged and reshaped. The greater opening area makes the crankcase lighter. The shape of the ventilation holes - wider at the top, narrower at the bottom - matches the actual flow of the trapped air, reducing pumping losses due to internal crankcase air-pressure resistance to downward piston movement.

New 4-2-1 exhaust system is significantly lighter, contributing to improved agility and handling. It is also increased mid-range engine power output further improving acceleration out of the corners.

Suzuki Exhaust Tuning (SET) servo-controlled butterfly valve in the exhaust pipe helps to maximize torque throughout the rev range in diverse running conditions by optimizing the exhaust-system back-pressure in accordance with the engine speed, throttle position, and gear posistion.

Finite-Element-Method (FEM) and fatigue-analysis techniques honed in development of MotoGP racebike engines were applied in making the pistons 11% lighter while retaining the same reliable level of strength and durability. The performance advantages translate into quicker acceleration and improved fuel economy.

Crankcase is refined with larger pentagonal cut-outs in the sides of each cylinder bore. The shape of the ventilation holes reduces pumping losses due to internal crankcase air-pressure resistance to downward piston movement.

Advanced technology from MotoGP competition was applied in modifying the camshaft profile. Thinner material for the tappet skirts results in a weight saving of 2.5 grams per tappet, reducing inertial mass and allowing optimization of the valve lift curve.
