O.S. Max-25XZ Truggy engine

O.S. Engines in Japan have announced their new truggy motor, the Max-25XZ. With the rules set for truggy racing, O.S. set out to make an extremely balanced, powerful and fuel efficient engine. The first thing was to reduce the capacity from .28 to .25 (4.09cc) which helped to make a more fuel efficient, lightweight engine with an improved centre of gravity. This short stroke engine claims a maximum power output of 3.1bhp at 33,000rpm and is supplied with a double adjustable carburetor to be able to fine tune the entire power range.

New Ninja engines made by O.S.

Following on from the announcement by GRP that they would stop producing engines for the Mugen owned Ninja brand, comes the first pictures of the new OS made Ninja motors. According to our site partners Neo Buggy, “the engine, OEM manufactured by OS engines for Ninja, is loosely based on their V-Spec with some custom features: the crankcase is from the OS 28XZ engine and does not feature the distinctive OS ‘black’ coating, the sleeve port design is a bit different from the V-Spec, head design, the crankshaft appears to have the same ‘DLC’ coating as the OS Speed V-spec but without counterweights. All in all a mix up of a few OS engines and Ninja branding.”
