Featuring Yamaha’s advanced racing technology, the new 2020 YZ450F has been updated to give racers the edge right out of the gate. Standard equipment including electric start, a lightweight lithium battery, advanced fuel injection, and a wrap around rear-positioned exhaust deliver powerful and reliable performance featuring industry leading mass-centralisation.
Racers can achieve quicker, smoother race starts with Yamaha’s Launch Control System, adjust their on-track performance using a smartphone thanks to the Yamaha Power Tuner App, and choose between two user defined ECU maps on the fly with the handlebar mounted dual-mode engine map switch.
The new 2020 YZ450F will be available from dealers next month in Team Yamaha Blue and Grey – pricing and availability are to be announced.
