OSSPEED's off-road racing engine has evolved even further. The "B2105", which evolved into the 5th generation of the B21 series, has been modified to secure the power to gain an advantage in the harsh off-road racing scene and to pursue a driving feel in any situation. The cylinder liner and crankshaft, which are the heart of the engine, have been changed. This has achieved a smoother increase in rotation. Furthermore, the lightweight outer head effect has also been combined to successfully improve drivability.
