Product Description

The O.S.SPEED R2106 Combo Set 2 (OS-1EY03) is a no-compromise high-end package for 1/8 on-road nitro racing. It combines the factory-tuned R2106 3.49cc (.21) competition engine with the TR03 EFRA2196 tuned pipe and MR05 manifold, delivering strong performance, crisp throttle response and a wide usable powerband.

The R2106 features a new 9-port cylinder liner with redesigned ports for increased output. For a strong feel from low RPM, it adopts the R21 Euro II crankshaft and a proven ceramic ball bearing, while a reinforced connecting rod improves durability under demanding on-road racing conditions.

The combo also includes key accessories such as the RP7 turbo glow plug, seals and collet, making it an excellent choice for racers looking for a complete performance-oriented setup.
