Stainless Steel Handlebar End Weight Bolt kit for CBR300R

This pair replaces the original external bar-end bolts, also described as handlebar end weight fixings, on Honda CBR300R 2015–2016. There is one fixing for the left weight and one for the right. The kit supplies bolts rather than new weights or internal mounting parts.

What you receive

• 2x stainless steel handlebar end weight bolts.
• 1x Biker Bling anti-seize compound pack (7 g).

Exclusions: Weights, internal weight assemblies, rubbers, retaining clips, mirrors and handguards are not included.

Important fitment notes

• Compatibility: For Honda CBR300R 2015–2016 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

• 90191-KYJ-900 – original external handlebar end weight fixing.

These references identify Honda’s original components, not Biker Bling product codes. The supplied parts are aftermarket replacements. Match each replacement to its intended position; a shared part number does not establish suitability at other mounting points.

Material and head style: The replacement fasteners are stainless steel and their heads may differ from Honda’s originals. Material alone does not establish the mechanical strength required for a mounting position.

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?

• Corroded or damaged heads: Check the fixings before removing the weights.
• Missing bolts: Check that each weight and its mounting components are complete.
• Bar-end servicing: Inspect the fixing arrangement whenever a weight is removed.

Fitting information

• Match each replacement to its original position and follow Honda’s tightening and thread-treatment instructions.
• Check both weights are secure and the right-hand weight does not restrict throttle movement or return.
• Use anti-seize or threadlocker only where specified for that fixing. A loose weight can indicate damaged internal mounting parts that new bolts will not repair.

For general background, read our guide to threadlocker and anti-seize on motorcycle bolts. Honda’s workshop procedure takes precedence.

Customer questions

Are the weights or internal rubbers included?

No. The kit contains two replacement bolts and the anti-seize pack. Weights, rubbers and retaining components are not supplied.

Will these fit aftermarket bar-end mirrors?

Check the mirror manufacturer’s mounting arrangement. Mirrors with expansion fittings or replacement weights may require different hardware.
