These two races might be something of a swan song for the MD250H and its race series. The CRF250X-powered Moriwaki will be unable to compete in the new four-stroke Moto3 class that's officially replacing two-stroke 125GP racing in 2012. Despite using a four-stroke motor of the correct capacity, Moto3 dictates a prototype engine and an 81mm bore, where the production-based motor in the MD250H has a 78mm bore. While the little Moriwaki provides a hint of what's to come from Moto3, it's likely the company will switch to producing a class-compliant bike with a new motor housed in a similar frame. Unlike the Honda-powered Moto2, Dorna promises Moto3 won't be a single-engine class.
