Racer X Films: Garage Build 2011 Yamaha YZ250 GNCC Race Bike

Who doesn’t love the sounds and smells of two-strokes? For this build we took an older two stroke and did everything we could to make it competitive with modern race bikes.

This time we went in a different direction, gearing this bike for the off-road GNCC series instead of a closed course motocross bike. Instead of racing 30 minutes, this bike was built for technical and tight 3 hour races, which means taking a completely different approach.
