Designed exclusively for the Yamaha YZF-R1 in RN32, RN49 and RN65 guise (2015–2026), these replacement fork guide bushings restore and elevate fork action through a thoughtfully layered construction — hardened steel core, copper undercoat, and a PTFE-coated contact surface — that moves far beyond the performance envelope of stock items.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDirect-fit replacement for Yamaha YZF-R1 RN32, RN49 and RN65 (2015–2026) — no modifications required\u003c\/li\u003e\n\u003cli\u003eHardened steel core with copper coating and PTFE-treated contact faces for minimal friction and extended service life\u003c\/li\u003e\n\u003cli\u003eReduced stiction throughout the fork stroke delivers smoother, more consistent damping response\u003c\/li\u003e\n\u003cli\u003ePrecise dimensional tolerances (43.00 mm ID \/ 48.00 mm OD \/ 12.00 mm height \/ 2.50 mm wall) ensure correct fit and alignment\u003c\/li\u003e\n\u003cli\u003eComplete set of two bushings covers both fork legs in a single purchase\u003c\/li\u003e\n\u003cli\u003eK-Tech quality control — trusted by professional race teams and demanding road riders alike\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eK-Tech Suspension has refined its bushing technology across decades of racing and road development. The GBS-015 reflects that accumulated knowledge in every detail: the hardened steel substrate provides the structural rigidity needed to maintain precise leg alignment under hard braking and high-speed compression loads, while the copper layer acts as a bonding medium that anchors the PTFE surface coating with exceptional tenacity. The result is a sliding surface that operates with noticeably lower friction than the original equipment, translating directly into more linear fork movement and better front-end feel — whether you are threading through a technical track section or leaning into a fast A-road sweep.\u003c\/p\u003e\u003ch2\u003ePerformance on Road and Track\u003c\/h2\u003e\u003cp\u003eOn the Yamaha YZF-R1, fork friction is a well-documented enemy of front-end feedback. Worn or sub-standard guide bushings introduce a choppy, inconsistent stroke that masks suspension tuning and erodes rider confidence. Fitting the K-Tech GBS-015 bushings eliminates that variable: the PTFE contact faces glide cleanly against the inner tube, the damping cartridge works as intended, and the R1's chassis communicates exactly what the front tyre is doing. For track riders running K-Tech cartridge conversions or DDS damper upgrades, fresh OEM-specification bushings are an essential baseline before any spring or damping adjustment.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe GBS-015 kit is engineered specifically for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 RN32 (2015–2016)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1 RN49 (2017–2020)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1 RN65 (2021–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInstallation requires specialised suspension tools and technical knowledge.
