The internets are a buzz today with photos from the MotoGP test a Sepang, which seem to suggest that the 2013 Honda RC213V prototype race bike has a 90° V4 engine configuration. The news should certainly come as a surprise for many Ducatisti MotoGP fans, as Ducati Corse’s front-end woes have often been attributed by couch racers to the Italian company’s 90° V4 engine configuration. Seeing how dominant Honda has been at the pre-season testing in Malaysia though, one cannot help but admit that the cylinder configuration is not necessarily to blame for Ducati’s troubles.
Talking to Spanish magazine SoloMoto, HRC boss Shuhei Nakamoto explains that the 90° V4 engine has benefits over the company’s previous 75° engine configuration, namely that the 90° engine doesn’t require a balancing countershaft. Nakamoto-san further explains that because of the balancing shaft’s absence, Honda’s 90° V4 runs with more power, and less vibration that its 75° predecessor, making the engine a formidable enhancement to the RC213V platform.
