Check what the kit actually contains

The caliper kit groups a sealing ring, two caliper bolts, bleed screw, cap and adjuster hardware. A piston is offered separately. Compare the kit with the condition and identity of the removed components before adding individual seals or fasteners.

A rubber cap and a bleed screw are different purchases

The stock-type bleed-screw cap is reference 45110-300-003. The alternative ten-pack is described as a universal-type choice for the SOHC group, with a different stock-type application for later models. Compare the cap design and fit instead of treating the larger package as identical.

Common questions

Is the piston included in the featured rebuild kit?

The kit lists sealing and external hardware; the piston is offered separately. Use the removed piston and the kit’s specific contents to decide whether your order needs both.

Can I choose the piston using the model year after a caliper swap?

Compare the actual caliper and removed piston. The offered replacement is 38.15 mm in diameter and 34 mm long, reference 45107-300-003. A motorcycle-year match alone does not identify an altered caliper.

Is the ten-pack the same stock-type cap as the single listing?

Do not assume that. The stock-type cap references 45110-300-003; the ten-pack has its own universal-type application wording for this model group. Match the cap to the bleed screw before choosing by quantity.
