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.”
