With the 2013 MotoGP season at its halfway mark, now is a good time to take a look back and examine the engine usage for the teams and riders. In 2012, with the engine durability regulations in their third full season, the factories appeared to have the situation pretty much under control. The only excitement arose when something unexpected happened, such as Jorge Lorenzo have an engine lunch itself after he was taken out by Alvaro Bautista at Assen last year. For 2013, the engine allocation was reduced from six to five engines per season. Each rider now has five engines to last the entire season, for use in all timed practice sessions during each race weekend.
