DescriptionThe whole story▼
Rooted in MotoGP and WSBK development, the TK Dischi Freno SSP 5.5 brake disc kit brings Italian race engineering directly to the Aprilia RS 660. Precision-drilled floating discs, a choice of anodised inner ring finishes, and certified materials combine to deliver a kit that is as visually distinctive as it is technically accomplished — equally at home on the road or the track.
Key Features
- 5.5 mm disc thickness strikes the ideal balance between reduced rotating mass and structural rigidity for consistent, fade-free braking.
- Angled through-drilling reduces operating temperatures by up to 20 % through even heat distribution, while simultaneously extending brake pad life and eliminating fade.
- Reduced rotating mass sharpens steering response and yields more agile, precise handling — a direct benefit of race-derived disc geometry.
- Inner ring available in hard-anodised, black, red, or blue — each finish produced to the same exacting Italian quality standard. Please note that red and blue finishes may require extended lead times.
- Manufactured in Italy from certified materials, developed and validated at the highest levels of motorcycle motorsport.
- Supplied as a matched pair (left and right) to ensure symmetrical braking performance from the outset.
Design, Finish and Heritage
TK Dischi Freno has built its reputation on the pit lane and the podium, translating the demands of prototype racing into hardware that road riders can actually specify. The SSP 5.5 series is the clearest expression of that philosophy: the angled drilling pattern is not decorative — it is the product of thermal analysis carried out at circuit level, where managing rotor temperature is a matter of lap time and safety alike. The four inner ring colour options let RS 660 owners personalise their front end without compromising on specification, and the hard-anodised treatment in particular offers a clean, factory aesthetic that complements the RS 660's sharply styled bodywork.
Performance on Road and Track
At 320 mm diameter — with a 330 mm option available — and a friction ring width of 34 mm, the SSP 5.5 kit is sized to work precisely with the RS 660's original caliper positions and brake line geometry. The angled drill pattern clears debris and moisture continuously, which means wet-weather braking confidence is measurably improved over a solid or conventionally drilled rotor. Consistent modulation under repeated hard braking is where the kit's motorsport lineage becomes most apparent: where OEM discs may begin to show fade under sustained track use, the SSP 5.5 maintains a firm, progressive feel throughout a session.
Fitment and Compatibility
This kit is developed specifically for the Aprilia RS 660 covering model years 2020 through to 2026. Both discs are supplied as a pair and are direct, bolt-on replacements requiring no modification to the original caliper, fork leg, or brake line hardware.
