Use this kit when renewing the fasteners that join the two halves of each front brake calliper on the Honda CBR900RR CBR954RR SC50 2002–2003. They are not the bolts that mount the callipers to the fork legs.

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.
Model-specific OEM replacements: The aftermarket replacements are selected for the SC50 calliper joining locations, with the critical fitting dimensions matched to the original positions. They are not genuine Honda bolts.
Head style and materials: The supplied bolts are A2 (304) stainless steel; their heads may look different from the originals. The 7 g anti-seize pack is included as a standard extra, not an instruction to lubricate brake fasteners.
When to replace these bolts
Inspect them during permitted calliper work, especially if a head is rounded, a bolt is corroded, or a thread has been damaged. Replacement fasteners cannot correct a cracked calliper, damaged mating face or hydraulic leak.
Fitting advice
Calliper assembly is safety-critical work. Use Honda’s workshop procedure and specified fastener treatment, tightening sequence and torque. Keep the brake system clean, then check for leaks and confirm normal brake operation before riding. See our motorcycle bolt strength guide for general fastener information. Get a qualified technician to assess damaged threads or any uncertainty about safe assembly.
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.
