Brake Disk W Series (Wave) MX King 150 X-Wheel WA9R 5 Hole MX 203mm

X1R HD Brake Disc Series W (Wave) MX King 150 Rear WA9R 203mm

Upgrade your MX King 150's rear braking performance with the X1R HD Brake Disc Series W, featuring the signature wave-cut design "The Power of Waves." Made from SUS 410 Japanese hardened steel at a durable 4mm thickness, this disc is precision ultra cut for better heat dissipation, giving it a super heat sink effect that helps maintain consistent braking performance under repeated hard braking.

The lightweight construction reduces unsprung weight for sharper handling, while the wave pattern also helps clear water and debris from the disc surface for more reliable stopping power. This WA9R rear disc has a 5-hole MX bolt pattern and a 203mm diameter, built specifically for the Yamaha MX King 150.
