From 2013, Moto3 replaces the 125GP and the bikes on the grid will be powered by Honda engines. The Japanese brand finally released a video about the new bike. The 250cc single-cylinder four-stroke engine can rev up to 14,000 rpm and should make close to 50hp. The new video gives us an idea what the final shape of the machine will look like. Watch the video and listen to the noise of the four-stroke engine.
