Honda CRF450R:
For 2020, Honda’s flagship CRF450R puts more engine-management choices at the fingertips of racers, with the addition of Honda Selectable Torque Control (HSTC). Developed through HRC’s worldwide racing effort, the system maximizes rear-tire hookup to keep all of the Unicam® engine’s horsepower driving the bike and rider forward, improving racing success regardless of track conditions.
It has the most aggressive character and is the most free-revving of all six 450cc MXers, which includes the Kawasaki KX450, Yamaha YZ450F, Suzuki RM-Z450, KTM 450 SX-F, and Husqvarna FC 450.
Revised mapping for riding modes in Standard, Smooth and Aggressive options, selectable via a separate handlebar-mounted switch.

More Powerful. Better Handling. Simply put, the 2020 YZ450F is better everywhere, with a more compact motor, a thoroughly refined and balanced chassis, and improved ergonomics to give the rider the ability to perform at their best, lap after lap.
