Description
Jetinetics Aluminum Total-Loss Flywheel for Yamaha 650/701 ? the lightest and strongest total-loss flywheel ever made at just 1.1 lbs, engineered to deliver lightning-crisp throttle response and violent acceleration that turns your Yamaha twin into an absolute weapon.
CAD/CAM designed and CNC-machined from premium billet aluminum in the USA, every ounce of unnecessary mass while the hardened steel ring gear ensures bulletproof starter engagement. No charging magnets means zero parasitic drag ? every bit of your engine?s energy goes straight to the pump instead of spinning a heavy stock flywheel.
Whether you’re building a 200+ HP big-bore SuperJet for freestyle or a razor-sharp 701 race ski for closed-course, this flywheel is the foundation of every serious total-loss setup. The precision dynamic balancing eliminates vibration even at 10,000+ RPM, and the compact diameter clears even the tightest aftermarket stator covers.
- Ultra-light 1.1 lb total weight ? fastest revving flywheel available
- Billet aluminum + hardened steel ring gear ? unbreakable
- CAD/CAM designed & CNC machined to aerospace tolerances
- Perfect dynamic balance ? smooth at any RPM
- Fits all Yamaha 650/701 engines (61X/62T)

This is the same flywheel that powered countless world champions and still dominates modern freestyle and race classes. Install it and feel your ski come alive ? the difference is immediate, the power addictive. When only the fastest will do, Jetinetics delivers.
