Yamaha R1 Captive Quick Change Wheel Spacers. These fit 2015 onwards models. I make these with a large head to allow them to slide into the bike easier and they have a retaining lip which holds them into the rubber dust seal found in your wheels. These don't fall out when you're trying to pry in the back wheel against the dreaded brake hanger 5 minutes before you're due out to try and win inters! Similarly, when you're trying to refit your wheels the night before your MOT, Take the stress out of wheel changes!
