Titanium Bolt M6x20 25 30mm Tapered ball Hex Socket Head Screw for Suzuki GSXR Yamaha Motorcycle Brake Disc, Pitch 1mm, by Tianswer

Precision CNC-machined Grade 5 Ti-6Al-4V titanium M6 tapered ball head brake rotor bolts engineered specifically for Suzuki GSX-R and Yamaha sportbike disc brake assemblies.

Engineering & Radius Ball Seat Geometry

Unlike standard flat countersunk or button head bolts, this specialized rotor bolt features a precision-machined radius tapered ball seat designed to mate perfectly with factory counter-bored rotor mounting holes on Suzuki and Yamaha wheel hubs. The ball seat geometry ensures optimal self-centering concentricity, uniform clamping pressure across the rotor carrier, and eliminates uneven stress risers that can cause brake disc warpage or pulsing under extreme thermal track conditions. Precision-crafted from certified aerospace Ti-6Al-4V (TC4 Grade 5) titanium alloy, it delivers tensile strength exceeding 950 MPa with high shear fatigue endurance.

Unsprung & Rotating Mass Reduction

Because brake disc hardware is mounted at the outer perimeter of the wheel hub, reducing bolt weight produces an immediate reduction in rotational inertia. Shaving roughly 45% of hardware weight compared to OEM steel bolts sharpens steering flickability, improves front-end suspension response over mid-corner bumps, and resists corrosive brake dust accumulation indefinitely.

Key Applications

• Suzuki Sportbikes & Street: GSX-R 600, GSX-R 750, GSX-R 1000, Hayabusa (GSX1300R), SV650, and GSX-S series front and rear brake disc rotors.
• Yamaha Performance Builds: YZF-R1, YZF-R6, YZF-R7, MT-07, MT-09, MT-10, and XSR series brake rotor mounts.
• Aftermarket High-Performance Discs: Brembo, Galfer, Braking, and Sunstar floating rotors requiring M6 ball-seat hardware.

Installation & Torque Recommendations

Thoroughly clean wheel hub threads of old threadlocker and debris prior to installation. Apply a medium-strength thread locker (or high-temperature anti-seize paste) to the leading threads. Always tighten in a star or criss-cross pattern in two progressive torque stages up to factory service manual specifications (typically 10–12 N·m for M6 rotor hardware). Use a calibrated manual torque wrench. Learn more about wheel and rotating hardware dynamics in our Unsprung Weight Reduction Guide.

Price is for 1 bolt. (Always replace rotor hardware in complete sets per wheel).
