Front Brake Disc Galfer Wave | Triumph Trident 660

You change front brake discs either to replace worn or warped discs, or to improve braking performance with high-performance discs. The front end delivers most of the braking power, so that is where the gain is most noticeable. Floating wave discs like these offer sharper braking, better modulation and optimised cooling compared with original discs. On a Triumph Trident 660, it is a major braking upgrade.

A floating disc consists of an outer braking track linked to a central carrier by rivets or bobbins that allow a slight play. This mounting lets the track expand freely under heat, without warping, which improves braking consistency and limits distortion under hard braking. Combined with a wave profile, it offers more precise, more enduring braking. It is a sporty design, valued for its behaviour when hot.

The Triumph Trident 660 has a twin-disc front end, one on each side of the wheel. It is essential to replace both discs at the same time to keep balanced, symmetrical braking. This product is therefore sold in pairs (2 discs), which guarantees consistent behaviour and even wear on both sides. Fitting a single new disc alongside a worn one is not advised.

They are designed for the Triumph Trident 660, model years 2021 to 2026, as a replacement for the original front discs. Their dimensions match the original: 310 mm diameter, 217 mm bolt circle, 5 holes. If you are unsure about your version or model year, check compatibility with us before ordering and we will confirm for you.

The discs fit on the original bolts, replacing the front discs: 1) Remove the front wheel. 2) Unscrew and remove both original discs. 3) Fit the Galfer discs, respecting the direction of rotation and the specified tightening torque (thread lock if specified). 4) Refit the wheel. 5) Progressively bed in the pads over the first miles, without harsh braking. As this is a primary safety part, this work is best entrusted to a professional.

Yes, high-performance floating front discs bring more consistent bite and better modulation than original discs, thanks to their increased leading edge and floating design. They improve cooling and behaviour when hot, which limits the drop in performance under repeated braking. The gain is felt most in sustained or sporty use. The pads and the condition of the braking system remain decisive for the result.
