Its moto-inspired architecture is built for predictable damping, control, and consistency under aggressive riding.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSur Ron Ultra Bee\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe F43 uses separate lubrication and damping oil circuits to optimize suspension performance, while the pressure-balanced closed cartridge maintains consistent damping through repeated impacts and long riding sessions. A hydraulic bump stop softens hard landings at maximum stroke, and external compression and rebound adjustments give riders direct control over fork behavior. Construction includes chrome-plated steel stanchions, hard-anodized 7050 aluminum outer tubes, and forged 6061 aluminum dropouts and triple clamps for a combination of strength and durability.\u003c\/p\u003e\n\u003cp\u003eInstallation is a direct swap for the stock Ultra Bee fork with no additional modifications or parts required. The dust seal and headset bearing come pre-installed on the steerer tube, and the supplied triple clamps and guards accommodate the Ultra Bee's existing fairing and cable routing. Spring rates and valving are available for different rider weights and riding styles, configuring the F43 for anything from technical trail riding to aggressive MX use.\u003c\/p\u003e","brand":"Sirris","offers":[{"title":"Trail - Light","offer_id":52123280146661,"sku":"SIRRIS-F43-T-L","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"Trail - Medium","offer_id":52123280179429,"sku":"SIRRIS-F43-T-M","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"Trail - Heavy","offer_id":52123280212197,"sku":"SIRRIS-F43-T-H","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"Trail - X Heavy","offer_id":52123280244965,"sku":"SIRRIS-F43-T-XH","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"Trail - XX Heavy","offer_id":52123280277733,"sku":"SIRRIS-F43-T-XXH","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"Trail - XXX Heavy","offer_id":52123280310501,"sku":"SIRRIS-F43-T-XXXH","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"MX - Light","offer_id":52123280343269,"sku":"SIRRIS-F43-MX-L","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"MX - Medium","offer_id":52123280376037,"sku":"SIRRIS-F43-MX-M","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"MX - Heavy","offer_id":52123280408805,"sku":"SIRRIS-F43-MX-H","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"MX - X Heavy","offer_id":52123280441573,"sku":"SIRRIS-F43-MX-XH","price":2249.99,"currency_code":"USD","in_stock":false},{"title":"MX - XX Heavy","offer_id":52123280474341,"sku":"SIRRIS-F43-MX-XXH","price":2249.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0511\/3964\/1496\/files\/sirris-F43-suspension-fork-lateral-1.jpg?v=1787132167","url":"https:\/\/gritshift.com\/fr\/products\/sirris-f43-premium-suspension-fork","provider":"GritShift","version":"1.0","type":"link"}
