O.S. Speed B21 Engine Adam Drake Edition Overview
“O.S. is passionate about winning and is the proven choice of champions. Working with the engineers at O.S. to develop the New B21 Adam Drake engine was amazing. Our goal was to provide customers with a configuration that is exclusive to O.S. and provides the power, run-time, and drivability to be used with both buggies and truggies. The B21AD uses the proven, easy-to-tune 21J carburetor, O.S. P3 Gold glow plug, ceramic rear ball bearing and lightweight cooling head. The DLC-coated crankshaft features two tungsten counterweights for smooth power delivery. If you're looking for the ultimate off-road engine that performs in both buggies and truggies, the O.S. Speed B21 Adam Drake is the engine for you!” — Adam Drake
