How Fast Can an 85cc Get? | Pro Circuit GasGas MC85 Build 

From the showroom floor to a full-blown amateur national weapon, we transformed the GasGas MC85 into a factory-level mini racer. With a Pro Circuit-built engine pumping out 28 horsepower, WP Cone Valve forks, an MX-Tech National shock, and a long list of premium race parts, this bike was built to compete with the fastest kids at Loretta Lynn’s. Our Mini Wrecking Crew testers immediately noticed the difference, turning lap times nearly three seconds faster than the stock bike. In this video, Josh Mosiman, Nixyn D’Errico, and Ryan D’Errico break down every major modification, explain why each part matters, and show what it takes to build a true elite-level 85cc motocross machine. If you’re serious about mini racing, this is the ultimate GasGas MC85 build inspiration.
