Replacing worn fork slide bushings is one of the most cost-effective suspension upgrades you can make to a Yamaha YZF-R1, and the K-Tech SBS-018 kit makes the job straightforward. Engineered specifically for the RN32, RN49 and RN65 generations (2015–2026), this complete two-bushing set restores smooth, precise fork action at a fraction of the cost of a full service from a suspension specialist.
Key Features
- Exact OEM replacement fit for Yamaha YZF-R1 RN32, RN49 and RN65 (2015–2026) — no trimming, no guesswork.
- Hardened steel core with copper coating provides a robust, corrosion-resistant foundation built for everyday road use and regular track days.
- PTFE-coated contact surfaces minimise friction against the fork tube, reducing stiction and restoring the R1's characteristic progressive fork feel.
- Complete kit supplies both bushings needed for a full axle-to-crown renewal in a single order.
- Precision ground to 41.70 mm inner diameter, 43.70 mm outer diameter and 30.00 mm height, keeping the fork geometry factory-correct after installation.
Build Quality & Performance
K-Tech's SBS-018 starts with a hardened steel shell — a step up from the softer alloys found in some aftermarket alternatives — and adds a copper interlayer that acts as both a bonding primer and a secondary bearing surface should the PTFE face ever see unusual load. The finished PTFE coating keeps the sliding interface almost entirely self-lubricating, which means reduced oil contamination from bushing wear and a fork that continues to feel crisp throughout its full stroke rather than notchy and reluctant near mid-travel.
For riders who commute during the week and chase lap times at weekends, that consistency matters. Stiction-free fork movement translates directly into better front-end feedback, more progressive braking feel and improved mid-corner stability — benefits you notice on the first exit of a long sweeper as much as on a fast chicane.
Fitment & Compatibility
This kit is designed exclusively for the following models:
- Yamaha YZF-R1 RN32 (2015–2016)
- Yamaha YZF-R1 RN49 (2017–2020)
- Yamaha YZF-R1 RN65 (2021–2026)
Installation requires specialist fork tools and techniques. K-Tech recommends fitting by an authorised K-Tech Service Centre to ensure maximum safety and correct pre-load setup.
