Motocross Action (MXA) puts BRC Racing’s Yamaha YZM500 two-stroke to the test in this one-of-a-kind build. Originally starting life as a YZ250 chassis, the bike was transformed with a 500cc two-stroke engine and put through its paces at Glen Helen Raceway.
This YZM500 features Psychic Motorsport components, including clutch plates, master cylinder rebuild kits, and a carburetor kit, delivering reliable performance and precise control under extreme conditions. Watch as MXA breaks down the build and puts this rare two-stroke machine through a true motocross test.
