Yamaha TT-R125 service parts: every part number for 2003 to 2023
Every service part and part number for the Yamaha TT-R125, the 125cc four-stroke trail bike bike, covering model years 2003 to 2023. The numbers come straight from Yamaha’s own parts catalogue, and each one links to the part on our site so you can check it fits and order it.
Part numbers change mid-model more often than people expect, so the year each number covers is given next to it. Check your bike’s model year before you order, and if you are not certain, ring the parts counter on 01570 470 022 with your model and year and we will look it up for you.
