TGP MotoRacing Titanium Brake Caliper Bolt Kit for Aprilia RS 660 (2020-2026)

Engineered from aerospace-grade Titanium Grade 5, the TGP MotoRacing brake caliper bolt kit for the Aprilia RS 660 (2020-2026) delivers a security-focused upgrade that never compromises on strength. Each bolt features rolled threads — a manufacturing method that compresses and aligns the grain structure of the metal, producing measurably higher tensile strength than cut threads and far greater resistance to fatigue failure. That engineering integrity is your assurance that shedding 85 g from your front brake hardware comes with no trade-off in reliability.

Key Features

• Rolled threads throughout: the compression-forming process creates a stronger, more durable thread form than cutting, reducing the risk of thread stripping under the cyclic loads experienced by brake calipers.
• Titanium Grade 5 (Ti-6Al-4V) construction: the gold standard for high-performance fasteners, combining the tensile strength of steel with roughly 45 % less mass.
• Full kit weight of just 85 g for four bolts — a direct, unambiguous saving over equivalent steel hardware without any loss of clamping force.
• M10 x 1.25 x 55 specification: machined to the exact thread pitch and length required by the Aprilia RS 660 front caliper mounts, ensuring a precise fit first time.
• Natural titanium finish: corrosion-resistant by nature, the surface resists brake dust, road grime and moisture without any coating that could wear away over time.
• Covers both calipers: two bolts per side, four in total, so your entire front brake assembly is addressed with a single purchase.

Strength Where It Matters

Brake caliper bolts live in a demanding environment. Every braking event loads them in shear and tension simultaneously, while heat cycling, vibration and road contamination slowly attack lesser fasteners. TGP MotoRacing specifies Titanium Grade 5 precisely because its fatigue resistance exceeds that of standard stainless steel, and the rolled-thread process adds a further margin of safety that track riders and road riders alike will appreciate. The result is a fastener you can torque to specification, leave in place and trust.

Performance and Aesthetics on the RS 660

The Aprilia RS 660 is a machine built around balance — every gramme removed from unsprung or braking-system mass contributes to sharper turn-in and more responsive deceleration. Replacing the stock caliper bolts with this TGP kit removes dead weight from a component that sees direct stress on every stop. The natural titanium surface also brings an understated, purposeful look to the caliper face that complements the RS 660's aggressive bodywork without resorting to anodised colour that can fade or chip.

Fitment and Compatibility

This kit is designed and supplied specifically for the Aprilia RS 660, covering all model years from 2020 through to 2026. It addresses the front brake calipers on both the left and right sides. No modification is required — the M10 x 1.25 x 55 thread specification matches the OEM caliper mount directly.
