320MM TRIUMPH BOBBER DISC

Boost your Triumph’s braking power with this 320 mm floating disc.

This 320 mm (12.60") floating brake disc delivers a significant increase in braking strength and consistency under demanding riding conditions.

With its larger diameter and floating construction, it offers a more precise lever feel, improved heat dissipation, and reduced vibration.

Developed by REMMOTORCYCLE, it is perfectly suited for the Triumph Modern Classic models listed below, as well as our REMMOTORCYCLE inverted fork kit for Triumph Bobber / Bonneville.

WHY CHOOSE A 320 MM FLOATING DISC?

Floating discs provide increased braking precision and thermal resistance:

• Better heat dissipation and reduced brake fade
• Lower unsprung weight for improved handling
• Reduced vibration and more even pad wear
• Increased durability thanks to premium materials

MATERIALS & MANUFACTURING

S42020 stainless steel: the same high-grade steel used by leading braking brands, offering an ideal balance between bite, power, and longevity.

6061 aluminum: used for the carrier and floating bushes; chosen for its mechanical strength and corrosion resistance, reducing weight while maintaining maximum rigidity.

CNC laser-cut machining: precision laser cutting followed by double-sided surface grinding within tight tolerances, minimizing vibration and ensuring a perfectly flat braking surface.

IMPORTANT — NON-COMPATIBLE MODELS

• Triumph Bobber model-year 2024 and newer: not compatible (new generation mounting layout).

If your model is not listed, the disc will not fit without custom adaptation.

INSTALLATION
