Coming soon from O.S. Engines is the new 3.5cc R2104 competition nitro on-road engine. The 9-port power plant was developed with this year’s IFRMAR 1/8th Nitro On-road World Championship in mind with an updated liner and piston increasing overall torque while the DLC-coated crankshaft offers improved transition between low and high RPM. The engine also sports a new combustion camber insert with a silicone O-ring, adapted from O.S. Engine’s off-road engines, preventing dust and dirt contamination. The R2104 is rounded off with a new design cooling head in a 2-tone black and red finish with white laser-engraved graphics. Beside the single engine O.S. also offers a combo package including the T-2080SC muffler and MR02 manifold.
