After the preview of last month, the Japanese OS has officially revealed features and release dates of the forthcoming Speed T-1203 and R21 Euro Spec engines (both designed for on-road racing). The R21 Euro Spec engine, designed for high-speed tracks by changing the crankshaft and cylinder / piston port timing and it features a new cooling head design, will be available this month. It will be sold as a combo set with the M2001SC manifold and T-2080SC exhaust.
