OS Speed Tuned B2101 per buggy in scala 1/8


In 2014 Ty Tessmann powered to first at the IFMAR Worlds running the Speed Tuned B2101, paired with a T-2090SC Tuned Pipe. The engine delivered for Ty — and its advantages can now belong to any off-road racer. 

Those advantages include faster acceleration, off the starting line and out of corners. A low center of gravity adds stability and predictable handling. Throttle response is so immediate, the power seems to flow right from the driver’s fingers. The factory-tuned, fiercely reliable B2101 is ready to keep the successes coming. Look for the B2101 now, with distinctive laser-etched Speed Tuned graphics on the cylinder head.

• Lowered machined cylinder head with maximized cooling
• DLC crankshaft with balanced tungsten weights and optimal intake timing
• Efficient, reliable Type 21J carburetor
