Original Honda fixing references
| Fitting position / component | Supplied quantity | Original Honda fixing reference |
|---|---|---|
| Left and right chain adjuster bolts | 2x | 90106-MCJ-000 |

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 supplied nut quantity is the retail pack allocation; it is not a count of every nut in the Honda diagram.
Model-specific OEM replacements: Biker Bling selects these aftermarket replacement bolts for the Honda CBR900RR CBR954RR SC50 rear chain-adjuster positions. Their critical fitting dimensions are matched to the original Honda fixings for these locations. They are not genuine Honda-branded parts.
Head style and materials: The two replacement bolts are made from A2 (304) stainless steel. The supplied nuts are included as replacement hardware; their material is not specified as stainless steel.
When should you replace chain-adjuster hardware?
- Replace a bolt or nut with damaged threads that will not turn or secure correctly.
- Renew corroded or damaged adjusters when carrying out rear-wheel or chain maintenance.
- If adjustment is difficult or the marks do not hold position, inspect the adjuster plates and axle area as well as the fasteners.
New bolts cannot repair a damaged adjuster plate, axle thread or swingarm.
Fitting the rear chain adjusters
Follow the Honda workshop instructions when setting chain slack and rear-wheel alignment. Make adjustments evenly on both sides, then secure the axle using the specified procedure and torque. Do not guess the setting. Before riding, check that the wheel is aligned and the chain slack is within Honda’s specification.

Customer questions
Does this include the axle or adjuster blocks?
No. The supplied items are the listed adjuster bolts, nuts and anti-seize pack.
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.
