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 6 to 5 per season. Each rider now has 5 engines to last the entire season, for use in all timed practice sessions during each race weekend. With three seasons already under their belt, no real drama was expected, yet that is not quite how it has turned out. While Honda and Ducati are right on course to last the season, Yamaha find themselves unexpectedly struggling. An unidentified design flaw has seen Yamaha losing engines too rapidly for comfort. Both factory Yamaha men have had an engine withdrawn, while there are question marks over the life left in one engine each allocated to Valentino Rossi and the two Monster Tech 3 Yamaha riders.
