Balance your braking with the X1R HD Wave Rear Brake Disc (Eb9R), a 190mm rotor engineered for smooth, reliable rear braking on the Honda Sonic 150. Made from SUS 410 Japanese hardened steel, it delivers long-lasting durability and stable performance ride after ride.

The ultra-cut wave-edge design with drilled holes 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.
