1981 Honda CB650C Custom · Front Caliper Parts Buying guide

Use the 1981 piston and hydraulic seal references

The piston replaces 45107-413-003 and the sealing ring 45108-300-003. A shaft boot protects a different location. Those distinctions matter when comparing a changed caliper or repair parts advertised across several Honda models.

Keep reference and year checks together

The piston’s written application explicitly includes the 1981 Custom. Do not bring forward the earlier piston’s published dimensions or dust-boot choice simply because another CB650C year looks similar. Compare the actual components and obtain the correct specification before beginning the rebuild.

Inspect before choosing the repair scope

The shaft boot replaces 45133-425-003 and is sold individually. Assess the caliper body, piston and sealing areas together so replacement rubber does not conceal a more serious condition. Have brake work carried out and checked using the correct service procedure.

Front Caliper Parts questions

Can I use the 1980 piston dimensions to order this one?

Do not transfer another year’s dimensions without verification. This product identifies reference 45107-413-003 and an explicit 1981 CB650C application; compare the installed caliper and correct part specification.

Does the replacement piston include its seals?

No. Part 99-5101 supplies one Japanese-made piston. The piston seal, dust seal, brake pads and hydraulic fluid are not included. Identify the correct rubber parts for the fitted caliper before building the rest of the order.

Is the piston confirmed genuine Honda?

The selected piston is a Japanese-made replacement. Genuine Honda manufacture is not confirmed, so choose it on its stated application and reference rather than assuming an OEM-branded part will be supplied.
