2021 Yamaha YZF-R1

Featuring next-generation R-Series styling, sophisticated electronic control, supersport braking and suspension performance and a high-performance crossplane engine.

Features may include:

• MotoGP®-Derived Crossplane Crankshaft Engine

The 998cc inline-four-cylinder engine features Yamaha’s exclusive crossplane crankshaft technology derived from the YZR-M1 MotoGP® machine. Every aspect of this unique engine is built to thrill.

• Digital Superbike Technology

The R1® features a cable-less ride-by-wire Yamaha Chip Controlled Throttle (YCC-T®) system that transforms the rider’s inputs into motion, with a full suite of IMU-powered electronic rider aids that bring new meaning to the term "rider confidence."

• 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.

• 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.

• 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.

• Supersport Braking Components

The YZF-R1 features 4-piston radial-mounte
