Yamaha YZF-600 R6

Riders can Experience the Exhilaration of R World with Complete Model Lineup

Yamaha Motor Corporation, USA, introduced the 2020 model-year YZF-R3 and YZF-R6 Supersport motorcycles, offering riders more opportunities to experience the exhilaration of R World on the street and track.

Welcome to R World
Yamaha has a rich heritage of building the most sought after Supersport motorcycles designed to deliver the pinnacle of performance on and off the track. From the rider-friendly YZF-R3 to the competition-focused YZF-R1M, the Yamaha R-series model lineup provides options for riders of all skill levels to experience the pure exhilaration of R World.

2020 YZF-R6 – Respect. Earned.
The YZF-R6 (R6) continues to be one of the most popular race-ready Supersport motorcycles ever built, succeeding as the number one choice for today’s racers who are looking to progress quickly through the competition ranks.

The 2020 R6 features Yamaha’s Chip Controlled Intake (YCC-I) for a broad, tractable powerband. A class-leading four-cylinder 599cc engine provides excellent performance, utilizing 16 titanium valves, a high 13.1:1 compression ratio, and lightweight forged pistons to allow for smooth, high-revving power. Linerless, direct-plated ceramic-composite cylinder bores provide excellent heat dissipation and reduced friction, while magnesium engine covers minimize engine weight.

The R6’s Deltabox aluminum frame incorporates years of GP development in terms of geometry, engine positioning, and rigidity, resulting in lightning-fast handling agility with confidence-inspiring mid-corner stability on the road or the track. A magnesium subframe removes weight from the rear of the motorcycle for increased mass centralization, while the flat and narrow seat makes it easier to reach the ground and gives riders more room to maneuver during aggressive racetrack riding.

Thanks to traction control that provides six levels of intervention or can be turned off completely, D-Mode for adjustable throttle response, YZF-R1 derived suspension, ABS brakes, top-notch aerodynamics, and an aluminum fuel tank, the 2020 R6 is poised to continue dominating the track while remaining ever-popular with street riders around the world.

The 2020 YZF-R6 will be available in Team Yamaha Blue, Raven, and Vivid Orange/Matte Raven Black.
