O.S. Engines have introduced their new Speed R21 Euro Spec.
This high level 3.5cc 1/8 On-road engine was developed especially for large European-style tracks with long straights as the updated piston, port and crankshaft timing will improve the peak performance which is needed for power-hungry tracks.
Furthermore the long-stroke engine comes with a redesigned cooling head for easy recognition and it is available as a combo set including the M2001SC manifold and T-2080SC exhaust pipe
