Superbike Brakes and Tires The YZF-R1® utilizes track-focused braking hardware, featuring potent 4-piston radial-mounted front calipers, stainless steel front lines, big 320mm rotors with high-friction pads and a compact ABS unit. The Bridgestone® RS11 tires ensure true racetrack-ready traction with balanced road feel and handling. ENGINE Cutting-Edge CP4® Engine The R1’s 998cc inline-four-cylinder engine features Yamaha’s exclusive crossplane crankshaft technology derived from the YZR-M1 MotoGP® machine. By equalizing inertial forces at the crankshaft, the CP4 motor delivers a direct feeling of linear torque, giving the rider the ultimate connection between throttle grip and the rear wheel. High-Output Engine Technology Titanium connecting rods use Yamaha’s precision fracture-split method to ensure reliability with minimal weight. Combined with titanium intake valves and forged pistons, these lightweight parts help achieve the CP4’s high redline and over-rev capability. The cylinder block is also offset from the crankshaft, reducing friction loads on the pistons and bores. High-Performance Intake System The cylinder head, intake system, fuel injectors and airbox work together to enhance part-throttle performance. And by creating a smaller and shorter intake tract, new injectors are able to spray fuel directly against the intake valves for improved fuel atomization. CHASSIS/SUSPENSION Brake Control (BC) System with ABS Developed on racetracks around the world, Yamaha’s Brake Control system works with an Antilock Braking System (ABS) to minimize brake slip under aggressive braking or on less than ideal surfaces. The adjustable BC system uses the IMU to provide progressive brake force intervention as lean angle increases which boosts rider confidence when braking mid-corner.
