Replacing the factory fork guide bushings with these hardened-steel, copper and PTFE-coated units eliminates the slop and stiction that blunt feedback on track, restoring the sharp, progressive response that makes the difference between a hesitant entry and a committed one.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDirect OEM replacement for fork guide bushings on the Kawasaki Ninja 400 (2018–2023) — no modification required\u003c\/li\u003e\n\u003cli\u003eHardened steel construction with a copper coating for outstanding wear resistance under sustained track use\u003c\/li\u003e\n\u003cli\u003ePTFE-coated contact surfaces reduce friction to a minimum, giving the fork a smooth, consistent stroke lap after lap\u003c\/li\u003e\n\u003cli\u003eComplete kit: two bushings supplied to allow a full axle-to-axle service in one go\u003c\/li\u003e\n\u003cli\u003eInner diameter 41.00 mm \/ outer diameter 45.00 mm \/ height 15.00 mm \/ wall thickness 2.00 mm — precision-machined to K-Tech tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance on Track\u003c\/h2\u003e\u003cp\u003eThe Ninja 400 has earned a strong reputation in junior and single-make racing classes, where suspension consistency separates podium finishers from mid-pack results. Worn or low-quality fork bushings introduce play into the slider-outer tube interface, generating a vague, deflective feel through fast chicanes and late braking zones. The GBS-007 kit closes that tolerance gap with its layered construction: a hardened steel core provides the structural rigidity to handle repeated heavy-braking loads, the copper interlayer distributes stress evenly, and the PTFE surface coating allows the fork legs to move with minimal breakaway friction. The result is a fork that responds immediately to input rather than lagging behind the rider's commands.\u003c\/p\u003e\u003ch2\u003eBuild Quality \u0026amp; Longevity\u003c\/h2\u003e\u003cp\u003eK-Tech's fork bushings are manufactured to the same standard as the components found in the brand's competition suspension products. The tri-layer material stack — steel, copper, PTFE — is the industry-accepted approach for high-cycle fork bushings because each layer serves a distinct function. Steel carries the load, copper absorbs micro-vibrations and prevents fretting corrosion, while PTFE keeps the sliding surface dry and clean without relying on fork oil for lubrication. This translates to a longer service life compared to plain OEM-style bushings, particularly in the abrasive conditions of track days and racing circuits.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe GBS-007 kit is designed exclusively for the Kawasaki Ninja 400 covering model years 2018 through 2023. It is not compatible with other Kawasaki models. Installation requires specialist fork tooling and a working knowledge of telescopic fork assembly; K-Tech recommends fitting by an authorised K-Tech Service Centre to ensure correct seating and safe operation.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInner diameter: 41.00 mm\u003c\/li\u003e\n\u003cli\u003eOuter diameter: 45.00 mm\u003c\/li\u003e\n\u003cli\u003eHeight: 15.00 mm\u003c\/li\u003e\n\u003cli\u003eWall thickness: 2.00 mm\u003c\/li\u003e\n\u003cli\u003eMaterial: hardened steel with copper coating and PTFE-coated contact surfaces\u003c\/li\u003e\n\u003cli\u003ePart number: GBS-007\u003c\/li\u003e\n\u003cli\u003eContents: 2 fork guide bushings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K-Tech","offers":[{"title":"Default Title","offer_id":53168833691914,"sku":"GBS-007","price":15.54,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/GBSKIT_13b2b404-7f2c-4a75-96c4-0232becb55e4.png?v=1780816994","url":"https:\/\/inter-pace.com\/products\/k-tech-fork-slide-bushing-kit-kawasaki-ninja-400-gbs-007","provider":"Inter-Pace","version":"1.0","type":"link"}
