Fork Boots (Gaiters) | Honda CB450 / CL450 / CB500K / CB550

The accordion rubber boots over your fork tubes are one of the first things to crack and fall apart on a fifty-year-old Honda. Once they're gone, road grit blasts the fork tubes and works its way into the fork seals. These reproduction gaiters cover the tubes back up and finish off the front end.

Why You Need This

The gaiters seal the gap between the lower fork slider and the triple tree, keeping dirt off the exposed fork tube and away from the fork seal. Worn or torn boots let grit reach the chrome and the seal, which leads to scored tubes and leaking forks. A fresh pair protects the tubes and makes the front end look right again.

These are a close reproduction of the originals. Honda used several fork styles across these models, so the gaiters are a close match, not an exact factory part.

Model-Specific Notes

  • Early CB450 / CL450 (K0–K2): These run a different external-spring fork. The fitment above starts at the K3 internal-spring fork — if you have an early external-spring front end, contact us before ordering.
  • CB350G / CL350: These use a smaller 33 mm fork, so this 35 mm gaiter fits only as a close, slightly loose substitute. For an exact fit, use the 33 mm fork dust boots made for the CB350 / CB360.

Installation

Difficulty: Beginner

Tools needed: None for the boots alone; basic fork tools if you're doing the seals at the same time

  1. The flat end of the gaiter goes down onto the fork leg, and the other end attaches up at the lower headlight bracket.
  2. The easiest time to fit new gaiters is during a fork rebuild, when the forks are apart. If you're in there, replace the fork seals too.

Frequently Asked Questions

How many do I need?

They're sold in pairs, so one order covers both fork legs.

Will these fit my CB350 or CL350?

They'll fit as a close substitute, but those bikes use a smaller 33 mm fork, so the gaiter's inner diameter runs a little larger than an exact match. For a precise fit, use the 33 mm fork dust boots made for the CB350 / CB360.

Are these an exact OEM part?

They're a close reproduction. Honda used several fork styles across these models, so the gaiters match closely but aren't a factory-exact part.

When should I replace them?

Whenever they're torn, split, or missing, and it's easiest to do during a fork rebuild while the forks are apart.

These gaiters were purchased for a Honda CB500K0. Nice fit, good quality rubber. Highly recommended for your 450's replacement.

Mr.
I just put these on the bike last night, so I can't speak to their longterm durability. But in regards to their ease of installation, no sweat. They are exactly what they say they are. They fit my 71 CL450 seamlessly, snugging firmly into their proper grooves with no setbacks. Hassle free. 5 stars.

Good Gaiters, make sure they are protected!
These are good quality gaiters. I would highly recommend using Aerospace 303 spray to protect them from UV light and to keep the rubber maleable. Otherwise, you might get some cracking of the rubber after a little while.

Great parts to revive an old Honda
There's nothing not to love about these parts. They fit great, they really make an old bike look nice and they're a great part for a new part. The Common motors crew is a great resource for anyone looking to bring an old bike back to life.
