YZ500 Conversions by Garage 11

The BRC YZ500 Conversion is the pinnacle of modern two-stroke engineering. By transforming Yamaha’s legendary YZ250 into a razor-sharp 500cc powerhouse, this kit delivers an unmatched combination of torque, horsepower, and agility. The BRC system features a purpose-built cylinder, head, piston, and crankshaft— all engineered with absolute precision to integrate seamlessly into the chassis.

The result is a machine that maintains the nimble handling of the YZ250 while producing the raw, explosive power only a 500 can deliver. Whether you’re chasing podiums or chasing that unmistakable 500cc feeling, the BRC platform is simply on another level.

What We Do

A YZ500 conversion is not just a bolt-on upgrade—it’s a specialised, high-precision process that we’ve perfected here at Garage 11. Our team handles the full installation of the BRC kit, including cylinder, head, piston, crankshaft, and all required modifications. Every component is fitted with meticulous attention to alignment, tolerance, and performance.

Once assembled, your engine is tuned, jetted, and test-ridden to ensure crisp throttle response, clean power delivery, and optimal reliability. We treat every build with the same care and obsession to detail that has defined Garage 11’s reputation across Australia and beyond.

From restorations to full 500 conversions, our work blends craftsmanship, engineering knowledge, and deep passion for the heritage of these iconic machines.
