Engine casing cover bolts for Triumph Speed Triple 1050 2005–2010

This model-specific kit supplies 74 stainless steel replacement bolts, two copper sealing washers and an anti-seize pack for the listed original clutch, alternator, crank, starter, sprocket-cover, water-pump and sump positions on the Triumph Speed Triple 1050 2005–2010.

For the 1050 cc generation in catalogue VIN group 210445–461331. VIN refers to the manufacturer’s chassis serial range, rather than the registration year alone. Check the model, year and matching original covers before ordering; this allocation is separate from the redesigned 2011-on model.

What you receive

• 74x stainless steel engine casing cover and sump bolts.
• 2x copper sealing washers for the listed crank-cover and water-pump positions.
• 1x Biker Bling anti-seize compound pack (7 g).

The original references below identify alternative factory fittings where applicable. Each affected position is counted once: the kit contains one applicable crank-cover bolt and one applicable pair of sprocket-cover bolts, rather than both complete alternatives.

The crank-cover sealing washer is supplied in copper at the original T3550403 position. Cooling item 57 is listed in the catalogue but is not separately illustrated in its original drawing; radiator bleed-washer item 42 is excluded.

Why choose a model-specific engine casing bolt kit?

Keep the cover groups organised by location and original diagram item, with different factory arrangements identified by their original references. This makes the allocation easier to compare with the existing motorcycle before cover maintenance.

Generic hardware photographs illustrate component styles. The contents table, original references and model-specific diagrams define the supplied allocation. Read our guide to generic and model-specific motorcycle bolt kits.

Fitment and coverage

• Compatibility: Triumph Speed Triple 1050, 2005–2010, catalogue VIN 210445–461331, with matching original components.
• Materials: Bolts are stainless steel and the supplied sealing washers are copper. Head style may differ from the original hardware. Original references identify fitting positions; these are aftermarket replacements, not genuine Triumph-branded parts.
• Modified motorcycles: Case savers, replacement covers or other accessories may require different hardware. Their additional mounting bolts are not included.
• Not included: Covers, gaskets, seals, dowels, oil filler parts, sump drain plug and washer, internal wire-retainer screw, separate cable-guide components, structural crankcase bolts, radiator bleed screw and washer, coolant-elbow fixings, hoses or clips.

When should you replace engine casing bolts?

Inspect corroded or rounded heads, damaged threads and missing fixings before cover maintenance. Replacement bolts cannot repair stripped casing threads, cracked covers or damaged sealing faces. Read our guide to when motorcycle bolts should be replaced.

Fitting information

Keep every fixing identified by cover and original position. Match the thread engagement, head clearance and sealing arrangement before fitting. Start threads by hand and follow Triumph’s workshop procedure for tightening sequence, torque and thread condition. The supplied anti-seize should be used only where that procedure permits; lubrication changes the relationship between tightening torque and clamping force.

Replace disturbed sealing components as specified by the workshop procedure and check for leaks after reassembly. Read our stainless steel bolt fitting guide and bolt strength grades guide.

Does this include structural engine bolts?

No. It covers only the listed casing-cover, pump and sump positions. Structural crankcase and engine-mounting bolts are excluded.
