The engine presented by Shineray was “developed” by the Italian company SWM, owned by a Chinese concern. The architecture of the two-cylinder V-shaped air-cooled engine is similar to the Harley power unit: the camber angle of the cylinder is 45 degrees, and the working volume is 1200 cubic meters. cm, compression ratio 9.1:1, similar cylinder diameter and piston stroke.
According to power indicators, the Chinese V-twin is also almost identical to the Sportster engine: the maximum power is 60 hp, and the peak torque is 90 Nm. Yes, the latest generations of the Sportster have a slightly higher compression ratio, 10:1, and the maximum power is greater, as much as 67 hp, but these are details. Even externally, the engine from Shineray is not easy to distinguish from the Sportster Evolution.
