This engine inherits the smooth and easy-to-use feel of the previous OS SPEED R21 EURO Spec engine. and by redesigning the crankshaft counterweight, low and mid-range power delivery has been improved.
The smooth speed drop and idle stability have also been improved, and the optimal performance is also demonstrated in long and hard racing use. Compared to the previous model, every part has been improved, including the outer head with new design to improve cooling performance.
The outer head has the same design as the R2104, which has both high cooling performance and light weight with original laser marking.

The 7 port cylinder and piston have a new design with additional cooling holes at the bottom of the exhaust with the redesigned crankcase
The crankshaft was designed specifically for this engine and uses 3 tungsten counterweights. This has improved mid and low speed torque feel and idle performance.
