  • 2001 Yamaha YZ250 2-Stroke Motocross Bike Build Garage Build

After over 30 years in the off-road parts business, we never stopped developing and improving our products. That’s why Polisport is an OEM supplier of some of the main motorcycle brands. We create exclusive technologies, constantly think of innovative products, and we always care for the customer. We make performance plastics!

For this special build, Jay Clark worked with one of his buddies, Donnie Bales, on a bit of goodwill/feelgood bike love. Usually I’ll go ride the bike a little after the initial photoshoot, but since this was such a special build, I decided to forego the riding and just let the owner, Johnny Posca, break it in first.

You see, Johnny’s dad, Jorge, had raced and ridden locally in Southern California since the 1970s. He purchased this 2001 Yamaha YZ250 brand-new and raced at some CMC, CRC, AMA, and District 37 races around Southern California. He loved it from the start and always said it was his favorite moto bike of all time. Jorge tragically lost his life in a 2009 auto accident, and his Yamaha sat in a storage shed until Johnny—a SoCal pro during the early 1990s—decided to resurrect it in his father’s honor.
