This allows for smooth rotation. Furthermore, the effect of a lighter outer head also overlaps, and we have succeeded in improving drivability.


The newly designed cylinder/piston uses 3 ports. The port shape has been changed and the air-fuel mixture flow has been reviewed to achieve more useful torque performance.


The newly designed crankshaft has undergone O.S.SPEED's traditional DLC processing and the internal shape has been revised to improve not only power characteristics but also rotational hold.


The outer head uses a new design. Succeeded in improving drivability in any situation by reducing weight.


The crankcase has inherited the well-established B2104.


The cover plate adopted from B2104 uses a specially treated thrust plate to reduce wear caused by interference between the rotating connecting rod and the cover plate, extending engine life.


A combo set with TB02 EFRA2089 pipe + MB01-75 manifold set is also available to maximize the B2105 engine performance (OS1EK01).
