• 1,043cc liquid-cooled inline-four offers true open-class power from idle to redline
• NEW Cylinder connecting passageways reduce pumping losses and improve mid-to-high RPM performance
• NEW Intake cams provide improved low-to-midrange torque
• Easily accessible torque offers instant thrust for maximum rider satisfaction
• Bore and stroke dimensions of 77.0 x 56.0mm offer an ideal balance of peak power and low
• and mid-range flexibility
• 38mm Keihin throttle bodies cram the air/fuel mixture directly into combustion chambers via downdraft intakes for maximum power
• Oval sub-throttles help keep the engine slim, and a slim midsection allows an ideal bike/rider interface for maximum comfort and control
• Engine’s rev limiter comes into play “softly,” providing usable overrev character because power doesn’t drop off suddenly at high RPM
• The engine’s relatively low crankshaft position allows a moderately long stroke without adding engine height
• A secondary engine balancer, driven off a gear on the sixth web of the crankshaft, eliminates excess vibration and contributes to rider comfort
