O.S. Speed R2106 1:8 Onroad engine
Legendary Japanese engine manufacturer O.S. Engines has released its latest .21 engine for 1:8 Onroad racing, the O.S. Speed R2106. The cylinder liner adopts a new 9-port shape, and the port shape has been revised to improve power in the mid-range. The crankshaft uses the well-known EURO2, and the combination with the rear bearing that uses ceramic balls has improved the feeling from the low-range. In addition, the connecting rod adopts a newly designed reinforced type, which improves durability in long and harsh racing scenes. The carburetor is based on the 21M, which was also well-received in the R2105, but the slide valve and needle shape have been changed to make it easier to adjust. It has been reborn as the O.S. Speed R2106, which can be expected to give you an advantage in racing.
