• 6x nylon washers.
• 1x Biker Bling anti-seize compound pack (7 g).

Important fitment notes

• Compatibility: For Honda CBR400R NC23 1986–1987 with the original component arrangement described above. Check aftermarket or modified components before ordering.
• Aftermarket parts: These are aftermarket replacements, not genuine Honda-branded components.
• Product photographs: Generic photographs illustrate the supplied style. Use the contents list for this kit’s scope.

Original Honda part references

• 90111-MB6-000 – original screen-setting fixing.
• 90202-MB6-000 – original screen-setting nut.

These Honda references identify the original mounting components. The supplied parts are aftermarket replacements, not genuine Honda parts. Match the correct fixing to its original position; alternative year references do not mean additional bolts are supplied.

Supplied bolt material: A2 (304) stainless steel. The material grade alone does not establish mechanical-strength equivalence to Honda’s original hardware.

When should you replace these fixings?

• Worn well nuts: Cracked, hardened or loose rubber fittings may no longer grip securely.
• Corroded or damaged bolts: Worn heads and threads can make screen removal difficult.
• Missing washers: Check the support around the mounting holes; damaged or missing washers can increase localised stress.

Fitting information

• Align the screen and fairing holes and check that the mounting points are undamaged.
• Seat the rubber well nuts and supporting washers in their intended order. Avoid overtightening or stressing the plastic.
• Follow the motorcycle and screen manufacturer’s instructions. Use anti-seize only where appropriate, and inspect the mounting points if the screen remains loose or rattles.

For general background, read our guide to fitting motorcycle fairing bolts without damaging plastic panels. Honda’s workshop procedure takes precedence.

Customer questions

Is this a complete fairing bolt kit?

No. It covers the windscreen-to-nose-cone fixings only. The side fairings, lower cowl and other bodywork fixings are not included.

Is 12 mm the bolt thread size?

No. It describes the large pan-head diameter. It is not a thread measurement.
