Front brake calliper joining bolts for Honda CBR600RR
This kit replaces the bolts that join the two halves of each front brake calliper on the Honda CBR600RR 2003–2006. These are calliper assembly bolts, not the bolts that mount the callipers to the fork legs.
What you receive
- 8x stainless steel calliper joining bolts – 4x for each front calliper.
- 1x Biker Bling anti-seize compound pack (7 g).
The callipers are not included. The dust plates clip into place, so this kit does not include separate dust-plate bolts.

These numbers identify the original Honda fixing positions, not Biker Bling product codes. The supplied kit contains aftermarket replacements, not genuine Honda parts. Year-specific references describe alternatives for their stated years, not additional supplied parts.
The references are year-specific alternatives, not additional supplied bolts. Follow the service procedure for the fitted calliper design.
Model-specific aftermarket replacements: Biker Bling supplies these bolts for the joining positions between the two halves of the front callipers. They are aftermarket parts, not genuine Honda components.
Head style and material: The supplied bolts are stainless steel. Their head appearance may differ from the original Honda fasteners.
When should you replace calliper joining bolts?
- Damaged or rounded drive recesses: Replace bolts that cannot be removed or refitted correctly.
- Corrosion or damaged threads: Inspect the bolt and calliper threads before reassembly.
- During authorised calliper service: Follow Honda’s instructions on whether the calliper may be separated and which fasteners should be renewed.
New bolts cannot repair damaged calliper threads, a cracked calliper body or a fault in the braking system.
Model-specific OEM replacements: Biker Bling selects the supplied replacement fasteners and fittings for the front brake calliper-half joining positions on the Honda CBR600RR 2003–2006, rather than supplying a generic assortment. The critical fitting dimensions match the original Honda fixings for those intended positions. These are aftermarket replacements, not genuine Honda-branded components.
Fitting the front brake calliper bolts
Brake callipers are safety-critical. Only separate the calliper halves if Honda’s service procedure permits it. Follow the workshop instructions for assembly, fastener replacement and tightening; do not guess a torque value. Keep friction surfaces clean and have the braking system inspected if the calliper, threads or seals are damaged. Before riding, check for leaks and confirm the front brake operates correctly. If you are unsure about the repair, have it carried out or checked by a qualified motorcycle technician.

Customer questions
Are these calliper-to-fork mounting bolts?
No. These fixings join the calliper halves. Use Honda’s exact service procedure for the fitted callipers.
Where should I use the anti-seize compound?
Use it only where the relevant motorcycle or component instructions specify a suitable thread treatment. Inclusion of the pack is not an instruction to lubricate every fixing.
