O.S. introduce new R21 Euro Spec & T-1203 engines
During the recent All Japan Model Hobby Show in Tokyo, Japan, O.S. Engines have introduced their forthcoming new Speed R21 Euro Spec and T-1203 on-road engines. Now more details and first official images have been made available. Starting with the 3.5cc R21 Euro Spec, the power plant 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 from October.
