This 81x-bolt kit replaces the fixings securing the original external engine covers listed below on the Honda ST1100 Pan European 1990–2003. The allocation separates the casing and secondary cover positions, so you can see exactly which mounting groups are included.

Original Honda fixing references

These numbers identify Honda’s original fixings, not Biker Bling product codes. The supplied bolts are model-specific aftermarket replacements, not genuine Honda-branded parts. Where alternative references are identified, they describe the same fixing positions rather than additional kit contents or a claimed supersession.

Important fitment notes

• Compatibility: For Honda ST1100 Pan European 1990–2003 with the original cover arrangement listed above. Check the exact year, variant and fitted covers before installation.
• Correct position: Keep the mounting groups separated and match each replacement to its intended hole. Bolts for different cover positions are not automatically interchangeable.
• Materials: The supplied cover bolts are A2 (304) stainless steel. Their head appearance may differ from Honda’s originals.
• Exclusions: Covers, gaskets, seals, dowels, drain plugs, drain bolts, sealing washers, internal engine fixings and unrelated bracket fixings are not included.

The kit supplies 81 replacement bolts in the groups listed. The seven generator-housing bolts are for the original early-type housing. Later or converted alternator arrangements may not use that group; check the fitted housing and do not substitute these bolts for different alternator fixings.

The generator-housing reference 90094-KE5-000 identifies the earlier original fixing at the same three positions. It is not an additional three bolts. Timing pulleys, belt-adjuster fixings, internal engine bolts, dowels and drain fixings are excluded.

When should you replace engine-cover bolts?

• Corroded or marked heads: Inspect the cover fixings before removal or servicing.
• Damaged threads or worn drive recesses: Replace unsuitable hardware and check the corresponding engine threads.
• Cover servicing: Check each fixing position and the sealing components before reassembly.

New bolts cannot repair a cracked cover, damaged sealing face, stripped thread or failed gasket. Investigate oil or coolant leaks rather than relying on extra tightening.

Fitting the engine casing bolts

• Follow Honda’s procedure for the exact cover, including draining fluids and renewing sealing components where required.
• Match every bolt to its original position, start it by hand and use Honda’s specified tightening order, torque and thread condition.
• Use anti-seize or other compounds only where the applicable instructions specify them. The included pack is not an instruction to lubricate every fixing.
• After assembly, check the relevant fluid levels and inspect disturbed covers for leaks. Have damaged threads or uncertain work checked by a qualified motorcycle technician.

For general advice, read our guide to protecting aluminium mounting threads. Honda’s workshop procedure takes precedence.
