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.

Thinner material for the valves' tappet skirts saves 2.5 grams per tappet, which reduces inertial mass and allows optimization of the valve lift curve.
