Part: Standard Fork Seals for Honda CB450, CL450 Scrambler, CB500T / CB500K, CB550 / CB750K0

Why You Need This Part: Fork seal replacement is the key to a proper fork rebuild on your vintage Honda and can even be installed with the fork tubes still in the triple tree. This is particularly beneficial in case you are working on your motorcycle in a place without workbench access (like in the driveway or on the streets). Thes are what we call "standard style" fork seals, which are the same kind used in the factory. One pair per bike. Finish your fork rebuild with some dust boots, or fork gaiters and our tapered roller steering bearing your front suspension and steering will be butter.

Note: CB450 and CL450 models used various fork designs during their production run. Make sure to pick the proper seal size for your model. If in doubt contact us for help. Seals do not require spacers and may not necessarily look like the ones in the picture above.

  • Early Style fits CB450 K1-K3* / CL450 K1-K4 / CB750K0 that use 35mm x 46mm seals - #8047
  • Late Style fits CB450 K3*-K7 / CL450 K5-K6 / CB500T / CB500 A-K2 / CB550K / CB550F / SL350 K2 that use 35mm x 48mm seals - #8010

*CB450K3 models had a fork change mid-production, the outer diameter of the seal must be measured to ensure the correct size is ordered.

Installation Tip: Lubricate the seals with fork oil during installation. A large circular punch (such as a short piece of pipe, stack of fender washers, etc.) will ensure the seal is pressed evenly into the lower fork tube. Drive the seals just deep enough to pass the snap ring groove and stop there. Factory spec on the fork oil varies on model, see list below. ATF (Automatic Transmission Fluid) is the factory specification for fork oil which is approximately 5W. We recommend a motorcycle specific fork oil: 10W (under 200 lbs rider) to 15W (200+ lbs rider) motorcycle. By using a heavier weight fork oil the front end of your bike well be will firmed up for better handling.
