About the Honda CR125R
Separate gasket-set years, fork oil seals and water-pump seal applications.
CR125R engine, suspension and brake changes
Honda’s 1986 CR125R used a liquid-cooled two-stroke engine, a front disc and a rear drum brake. That year-specific combination shows why the complete model year and brake position matter. Later or replacement forks, wheels and calipers need their own application checks.
Choose engine gaskets and fork seals independently
The 1990–1997 CR125R engine gasket set and the 1998 set are separate products. The featured fork oil seals list 1997–2007, while the water-pump mechanical seal lists 1981–1983. Each range belongs to that component; use the engine or fork fitted to narrow the correct choice.

| Water-pump mechanical seal | 1981–1983 | Pump / seal reference |
| 1990–1997 engine gasket set | 1990–1997 | Engine and kit contents |

Follow the product link for each application. An engine-gasket year range does not extend the coverage of a fork or water-pump seal.

Engine work
Different gasket-set selections
Compare the 1990–1997 CR125R engine gasket set with the 1998 CR125R engine gasket set. Check the gasket shapes and repair coverage before opening the engine.
Suspension work
Oil seals and dust seals
The 1997–2007 CR125R fork oil seals are listed separately from dust-seal products. Check which parts your service requires and whether the fork is original.
Motorcycle and component detailsCR125R identification checklist
- Frame and engine: Confirm the model year and record the engine identification if it has been changed.
- Fork identification: Match the installed fork and seal dimensions rather than frame year alone.
- Brake assembly: Confirm front or rear, disc or drum, and the caliper or hub fitted.
- Gasket and seal contents: Compare the supplied pieces with every joint or seal being serviced.
