Congratulations to Dain Sires of Cedar Falls, Iowa on his conversion of a 2015 YZ450F! I absolutely love the clean look of the battery and motor mount treatments on this build. YZ’s are one of my favorites and Dain has done an excellent job with the design, engineering and fabrication of this bike’s streamlined and factory like finish. Here are the build details.
Build specifications
- 2015 Yamaha YZ450F chassis/suspension
- Motenergy ME1304 PMAC Motor
- Sevcon Gen4 Size6 motor controller
- Domino Throttle assembly
- 3kwh 24S prismatic cell lithium pack (2x Honda Clarity 12S modules) 100.8V peak
- AMP 10T front sprocket, Vortex 60T rear sprocket – Cycle Analyst V2.4, remote shunt
- Decals by Rooster Graphics of Des Moines, Iowa
Performance and project goals
The goal of this build is to achieve a level of performance similar to a modern 450cc EFI fourstroke motocross bike for a period of 10-15 minutes of intense track riding. In current phase of tuning/build the performance is significantly higher than a 250F, but not quite to 450F levels of power. Low end torque is tolerable, the bike shines between 20-40mph. Next steps are to liquid cool the motor and add a heat sink to the controller.
