The gearbox recall for the 2015 Yamaha YZF-R1 was a massive undertaking. In total, the recall affected 2,921 motorcycles, with Yamaha estimating almost 16 hours of labor per bike in order to change out the gearbox. That’s a lot of shop time for each individual motorcycle.
That time isn’t cheap either, and the cost of the labor alone was somewhere around the $5 million mark. By the time you threw in the cost of the parts, the R1 recall likely cost Yamaha somewhere north of $10 million.
To get a sense of how long that recall work took, checkout this time-lapse video that a mechanic made while working on one of the affected superbikes. Be sure to note that the video spans two days of shop time. It’s quite the process.
