NG BRAKES Round Fixed Brake Disc for YAMAHA DT 50, TTR 125 1998-2021

NG offers this brake disc for YAMAHA DT 50, TTR 125 1998-2021. The disc is bolted to the wheel and turns with it. When you brake, the caliper squeezes the pads against the disc: the friction turns speed into heat and the wheel slows down.

Why replace your brake disc?

The benefits:

• Get back strong, steady braking, with no vibration in the lever or pedal.
• New pads last longer on a disc that is flat and the right thickness.
• Diameter and bolt holes made for your bike: it fits in place of the original disc.

When should you replace the brake disc on your YAMAHA TTR 125?

Measure the thickness with a micrometer: below the minimum stamped on the disc, or if it is warped or cracked, it must be replaced.
