TGP MotoRacing Titanium Brake Caliper Bolt Kit – Aprilia RSV4 / Factory / R / RR / RF (2009–2016)

Every gram saved on unsprung and rotating mass matters on a machine as capable as the Aprilia RSV4, and the TGP MotoRacing titanium brake caliper bolt kit is engineered to deliver exactly that — a measurable weight saving combined with a level of material quality that OEM steel hardware simply cannot match. Built from Grade 5 titanium with roll-formed threads throughout, this four-bolt front caliper kit is the kind of detail that separates a properly prepared RSV4 from one that just looks the part.

Key Features

• Grade 5 titanium construction offers an exceptional strength-to-weight ratio, significantly outperforming standard steel caliper bolts in both tensile strength and corrosion resistance.
• Roll-formed threads rather than cut threads — the rolling process compresses and work-hardens the thread profile, resulting in greater fatigue resistance and a longer service life under the cyclic loads of hard braking.
• Complete kit of 4 bolts covers both front brake calipers (2 bolts per caliper, left and right), with a total kit weight of just 85 g.
• M10x1.25x55 specification ensures a precise, rattle-free fit to Aprilia RSV4 front caliper mounting points across all variants from 2009 to 2016.
• Natural titanium finish adds a purposeful, motorsport-grade aesthetic to the front end without the need for any additional finishing or treatment.
• Inherent corrosion resistance of Grade 5 titanium makes these bolts equally at home on track days in the wet or under the salt-laden conditions of road use.

Material Quality and Engineering

Grade 5 titanium — formally Ti-6Al-4V — is the alloy of choice across aerospace and motorsport for good reason: it combines the tensile strength of steel with roughly 45 per cent less mass, while offering outstanding resistance to both corrosion and fatigue. TGP MotoRacing specifies roll-formed threads on every bolt in this kit. Unlike cut threads, which sever the grain structure of the metal, rolling deforms the material plastically, aligning and compressing the grain flow around the thread form. The result is a thread that is measurably stronger, more resistant to stripping, and better able to cope with the vibration and thermal cycling found in a high-performance braking system.

Performance and Track Application

At 85 g for the complete four-bolt set, the saving over equivalent steel hardware is tangible at the front axle — an area where reducing unsprung weight directly influences steering response, fork action, and overall feel through the front end. For riders who use their RSV4 on circuit, where every component is scrutinised for its contribution to the whole, a titanium caliper bolt kit is a logical and cost-effective upgrade. On the road, the corrosion resistance alone justifies the switch: titanium will not seize into the caliper carrier the way steel bolts can after a winter of wet riding, making future maintenance considerably more straightforward.

Fitment and Compatibility

This kit is designed specifically for the front brake calipers of the following Aprilia models:

• Aprilia RSV4 (2009–2016)
• Aprilia RSV4 Factory (2009–2016)
• Aprilia RSV4 R (2009–2016)
• Aprilia RSV4 RR (2009–2016)
• Aprilia RSV4 RF (2009–2016)

Thread specification M10x1.25x55 matches the OEM caliper mounting bolt dimensions for all listed variants. Always verify fitment against your specific build before installation.
