Get smooth, consistent rear braking with the X1R HD Wave Rear Brake Disc (WA8R), a 200mm rotor designed for Yamaha LC135, MX King 135, Y125 and Sniper 135. Made from SUS 410 Japanese hardened steel, it delivers long-lasting durability and stable performance ride after ride.

The large-cutout wave design keeps the rotor light and helps shed water and brake dust, while the super heat sink structure disperses heat efficiently to keep braking consistent. With a 4mm thickness, it gives you the strength you need without unnecessary weight.
