Advanced Twin Cylinder Engine The XSR700 features a compact 689cc liquid-cooled, inline twin-cylinder, DOHC engine with fuel injection. This engine provides a unique power character, with outstanding low- to mid-range torque and very linear throttle response, combined with strong high-rpm pulling power. This motor develops 50 foot pounds of torque and is designed to maximize riding excitement in the real world.
|
Crossplane Crankshaft Concept The 2-cylinder engine features Yamaha’s “Crossplane Concept” 270 degree crank that provides linear torque development in response to the rider’s throttle input. The CP2® engine is also light, slim and compact and offers an excellent level of rider/machine communication
|
Offset Cylinder Block The paired cylinders of the XSR engine are shifted slightly forward compared to the center of the crankshaft. This reduces drag during each combustion stroke of the pistons and improves efficiency.
|
Vibration-Reducing Counterbalancer To reduce vibration and provide a smooth, modern engine character, the motor uses a geared counterbalancer, mounted low and forward on the engine.
|
Refined, Efficient Fuel Injection Electronic fuel injection settings deliver a smooth throttle response to enhance riding enjoyment from open roads to the urban sprawl. The system delivers outstanding torque in the low- and mid-rpm range along with exciting acceleration in the upper rpm range. Combined with the efficient overall engine design, the XSR700 delivers an exceptional 58 mpg.
|
Compact 6-Speed Transmission The XSR700’s 6-speed transmission takes full advantage of the low-to- mid-range torque and excellent response of the twin-cylinder motor, while further enhancing the compact engine design thanks to triangulated input and outputs shafts.
