1974 Yamaha RD350, Custom Ninja 250 hybrid

Built from the ground up custom 1974 Yamaha RD350. This was built over a few years and took over $10,000 and several hundred hours of labor. Nothing was left alone. The engine was rebuilt, resh paint on the body parts, ew hardware, ew wiring and gauges etc. It has been grafted with 2008 Ninja 250 front and rear suspension and brakes. Makes for a classic looking two stroke with modern suspension and brakes. Rides excellent and stops like a motorcyle should! Bike had 8,000 miles before the rebuild. I’ve put ~50 miles on it.
