The OS Speed B2103 Type R engine is a 5-port long-stroke motor. It impresses with its high torque in the mid to high RPM range, featuring linear power delivery and low consumption. The crankcase, crankcase cover, and carburetor have a completely new design. The new DLC-coated crankshaft is equipped with two tungsten weights for perfect balancing and maximum smoothness. The B2103 Type R features a high cooling head for optimal cooling in high ambient temperatures. An O-ring between the cooling head and combustion chamber insert reduces vibrations and protects against contamination through optimal sealing. The new 22E carburetor ensures perfect throttle response and maximum power output.
