Why The Head Is The Critical Part
Fork bushings have a PTFE lining on an aluminum backing. Over time — and sometimes right out of the factory — they go slightly out of round or end up with bore geometry that doesn't match the stanchion correctly. The result is uneven contact: high spots that drag on the stanchion creating friction and stiction that no spring rate or oil weight change can fix.
The burnishing head is the part that does the work. Machined slightly larger than the nominal stanchion diameter, pressing it through the bushing corrects the bore — re-rounding it and sizing it to a precise, controlled fit. No seals need to be removed. The process takes minutes and the result is permanent.
Who This Is For
-
Adding a New Fork Size
Already own the RMS handle but picking up a new fork? Just add the head you need. Every RMS head fits any RMS handle — no new kit required.
-
Expanding Your Range
Building out your kit over time? Add heads one at a time as you need them, or grab the Full Set of all 7 sizes at once and cover every fork that comes through your stand.
-
Adding a New +Size
Already burnished with +.07mm and want to try +.10mm on a stubborn fork? Just order the head size you need in the new +size — your existing handle works with all of them.
Tool Features
• High-strength polished steel — same material and finish as every RMS head; built to last through years of regular use
• Self-aligning head geometry — centers itself as you press through; no fighting alignment mid-pass
• No seal removal required — cleaner and faster than traditional bushing service methods
• Surface finish optimized for burnishing — retains lubricant and minimizes drag during the pass
• Interchangeable with all RMS handles — fits any RMS burnishing tool handle, any year
• Made in Canada

Frequently Asked Questions
Which handle does this fit?
All RMS burnishing heads fit any RMS burnishing tool handle regardless of when it was purchased. If you already own the tool, just swap the head onto your existing handle — no adapter or modification needed.
How do I know if my fork needs bushing sizing?
The clearest sign is a fork that feels harsh, sticky, or unresponsive — especially at small bumps — and doesn't improve meaningfully after a full service with fresh oil and seals. If the fork feels acceptable right after a service but degrades within the first ride or two, that's a strong indicator the bushings need sizing.
Which +size should I use?
It depends on how sticky the fork feels. If the fork generally feels okay but not great, and doesn't degrade quickly after a service, the +.07mm is likely sufficient. If the fork feels noticeably sticky or harsh, or degrades within the first ride after a service, start with +.10mm. If the fork still has stiction after burnishing with +.10mm, move to +.13mm. Important: for +sizes larger than +.10mm, always run the +.10mm head through first — some forks have very tight bushings that make jumping straight to a larger +size difficult. The +.10mm gets the majority of forks feeling great on its own.
Will the bushing end up exactly at the +size diameter after burnishing?
No. The PTFE bushing material has spring-back after the tool passes through — the bore shrinks back down once the head clears. The larger the +size used, the more spring-back occurs, so the relationship between head size and final bushing diameter is not linear. All three +sizes (+.07, +.10, +.13mm) will result in a final bushing clearance in the ideal range of approximately .05–.10mm (.002"–.004"), which provides the right amount of clearance for proper oil film formation without excessive play.
Can I over-burnish or damage the bushings?
No. You cannot over-burnish — you could work each bushing for an hour and not go too far. As you pass the tool back and forth, resistance will gradually decrease until it levels off and becomes constant. That plateau is your signal that the bushing is done. It's normal for upper and lower bushings to feel slightly different from each other — what matters is that each pair feels consistent side to side.
Will there be play in my fork after burnishing?
All forks have a small amount of clearance between the bushings and stanchions by design — zero clearance would mean the fork couldn't move. That clearance means there is technically some play present before you even start, and burnishing doesn't meaningfully increase it. The correct amount of play after sizing should be essentially unnoticeable while riding and barely detectable in a static test. Note: what feels like fork play in static parking lot tests is often a loose headset or brake caliper float, not bushing clearance.
Do I need special oil for burnishing or after burnishing?
Use whatever oil your fork manufacturer specifies. No special oil is needed for the burnishing process itself. One tip: thicker oils will mask bushing clearance better than thinner oils, so oil weight is worth considering alongside bushing sizing when chasing feel.
