The next generation of on-road performance.

The next generation of on-road performance has arrived with the Speed R2103 from O.S.! Capable of a wider range of torque than the R2102, the Speed R2103 dominates even on high-grip surfaces. Superior fuel consumption ensures you get the most mileage from every fill-up. Factory-applied two-color graphics add signature style to this sleek-looking power plant. Includes a polished aluminum T-2080SC Pipe Set that’s tuned specifically for competitive performance.
  • Compatible with 16% nitro fuel, which complies with EFRA regulations.
  • T-2080 Pipe Set, constructed of polished aluminum and tuned for competition.
  • Crankshaft with Diamond-Like Coating (DLC) and an embedded tungsten weight.
  • Outer head with factory-applied two-color graphics.
  • Second inner button head allows for finer tuning to meet track conditions.
  • Steel rear ball bearing.
  • Slide valve carburetor.
  • 8.5 mm reducer installed in the carburetor venturi to reduce the amount of airflow for greater torque.
  • Turbo RP7 glow plug.
