Podium power for 1/8 scale buggies

O.S. holds the record for most IFMAR 1/8 Scale World Championship wins of any brand. That record continued in 2014 when Ty Tessmann powered to the IFMAR Worlds podium with the O.S. Speed B2101, paired with the performance-boosting T-2090SC Tuned Pipe.

The B2101 delivered for Ty. And its advantages can also be yours.

They include faster acceleration off the starting line and out of corners...a low CG for stability and predictable handling...and throttle response so immediate, the power seems to flow right from your fingers.

Top drivers everywhere choose O.S. to dominate in local, regional and national competitions. The factory-tuned, fiercely reliable B2101 is ready to put you on the podium, too.

 

  • Designed specifically for maximum power output, performance and tuneability in 1/8 scale buggy applications.
  • Machined cylinder head with laser-etched Speed Tuned graphics lowers the center of gravity and improves cooling.
  • Features a DLC-coated crankshaft balanced with tungsten weights and the efficient, reliable 21J carburetor.
