We know you like to go fast or cruise all day, but when you need to stop, you'll be dependant on Single disc front brakes and Expanding brake (drum brake) rear brakes. The Yamaha Mio S was launched in 2021, and we're happy to know (or assume) you've got one in your garage. To help you keep your ride in tip-top shape, consider purchasing an owner or service manual.
