TUSK Fork & Dust Seal Rebuild Kit for CRF110F/125F/XR150L/TTR110E — Complete fork seals, foam rings, dust boots

If your bike’s front end leaks oil, feels inconsistent, or has degraded travel, the right seal kit restores reliable fork performance without a full fork replacement. The TUSK Fork & Dust Seal Kit gathers all internal wear pieces you typically change during a front-fork service, so you can address leaks, contamination, or sag in a single maintenance session. This kit is made to fit specific Honda and Yamaha models and includes parts matched to original internal dimensions for a direct, streamlined installation.

What exactly comes in this rebuild kit and why does each piece matter?

The kit contains the replaceable fork seals, dust boots, inner foam rings, and the small hardware required to rebuild a fork leg. Each component has a targeted role: seals stop oil loss, dust covers block dirt, foam rings retain lubricating oil, and hardware secures the assembly. Replacing everything at once prevents early failures caused by mixed old and new parts.

• Primary fork oil seals sized to match OEM internal diameters
• Weather-resistant dust covers to keep grit out of the fork internals
• Foam rings that help maintain lubrication and smooth travel
• Included fasteners and any small components needed for reassembly

How difficult is installation and what tools or steps should I expect?

Installation is straightforward for anyone comfortable with routine motorcycle maintenance and basic tools. You’ll disassemble the fork leg, remove old seals and foam, fit the new parts, refill with the correct fork oil, and reassemble following torque specs from your service manual. No specialized machining is required, though a clean workspace and adherence to the manual improve outcomes.

• Requires common hand tools, torque wrench recommended
• Fork oil must be chosen per your motorcycle’s service manual
• Clean parts and organized workspace reduce risk of contamination
• Professional shop service advised if you’re unsure about fork disassembly

Which motorcycles does this TUSK kit fit and how can I verify compatibility?

The kit lists compatibility with a range of small-displacement Honda and Yamaha models across multiple years; exact fitment depends on your bike’s model and production year. Use the included fitment guide image and cross-check part numbers against your OEM references to confirm compatibility before purchasing. When in doubt, compare the fork internal dimensions or consult a dealer with your VIN.

• Compatible with select Honda CRF110F, CRF125F, GROM, Monkey, XR150L, DAX, ADV 160, TR200R models
• Compatible with Yamaha TTR110E models from 2008–2026
• Contains OEM replacement numbers for cross-reference
• Refer to the fitment guide image and service manual for verification

What performance improvements can I expect after installing this kit?

Replacing worn fork seals and internal wear items restores smoother travel and consistent damping behavior, while dust covers reduce contamination that accelerates wear. You should notice reduced oil seepage, more predictable front-end feedback, and improved ride quality when parts were previously degraded. Results depend on correct oil level and condition, and on the overall condition of the fork tubes and internals.

• Eliminates most common oil leaks from aged seals
• Helps return predictable fork rebound and compression
• Reduces contamination-related wear with new dust boots
• Improved longevity when installed with proper oil and service practices

This kit is ideal for riders performing routine preventive maintenance, repairing visible oil leaks, or completing a front‑end rebuild on compatible small-displacement motorcycles. It suits DIY mechanics who have basic mechanical skills and the required tools, as well as professional shops seeking a convenient, matched set of replacement components. Always confirm model and year compatibility and follow your motorcycle service manual for fluid types and torque specifications to ensure safe, reliable results.
