{"product_id":"stm-fhn-s080","title":"STM Slipper Clutch Honda CBR 1000 RR (2008-2019) FHN-S080","description":"\u003cp\u003eRooted in decades of Italian racing engineering, the STM slipper clutch for the Honda CBR 1000 RR (2008-2019) represents the kind of precision hardware that separates a street-legal sportsbike from a genuinely track-ready machine. Part number FHN-S080 is a direct-fit replacement that transforms the clutch character of the CBR completely, replacing the factory unit with a system designed to the exacting standards STM have applied to championship-winning machinery for years.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrevents engine over-rev under hard downshifts, delivering composed, controlled deceleration in place of the unsettling lurch the stock clutch can produce\u003c\/li\u003e\n\u003cli\u003eActively reduces rear wheel hop and skip, improving traction and stability precisely when the bike is most vulnerable — deep into a braking zone\u003c\/li\u003e\n\u003cli\u003eSignificantly lowers the risk of a highside by limiting the triggering impulse that causes sudden, violent rear-wheel grip recovery\u003c\/li\u003e\n\u003cli\u003eAllows a controlled, predictable rear slide — a genuine advantage during aggressive cornering entries and track sessions\u003c\/li\u003e\n\u003cli\u003ePatented ball-ramp mechanism governs the slipper function with measurable precision, maintaining consistent behaviour across a wide rpm range\u003c\/li\u003e\n\u003cli\u003eDiaphragm spring replaces the conventional pressure plate, eliminating plate judder and producing a markedly cleaner lever release feel\u003c\/li\u003e\n\u003cli\u003eApproximate weight saving of 0.7–0.8 kg over the OEM unit by reducing rotating mass, directly benefiting acceleration response and overall handling agility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSTM have been crafting slipper clutches in Italy since the technology first migrated from Grand Prix paddocks to production machinery. The FHN-S080 carries that lineage in every detail — from the close-tolerance machining of the basket and hub to the anodised finish that distinguishes it instantly from the grey anonymity of a standard clutch assembly. This is components-as-craft: functional sculpture that earns its place under the fairing on visual merit alone, before you consider what it does for lap times.\u003c\/p\u003e\u003cp\u003eThe ball-ramp antihopping system is at the heart of STM's design philosophy. Rather than relying on a simple slip mechanism, the patented ramp geometry allows the clutch to modulate lock-up force progressively, matching rear-wheel deceleration to available traction with a finesse that passive systems cannot replicate. The result is a clutch that feels intuitive within a handful of laps, giving the rider the confidence to brake later and harder.\u003c\/p\u003e\u003ch2\u003ePerformance on Road and Track\u003c\/h2\u003e\u003cp\u003eFor CBR 1000 RR owners who regularly use the bike in a sporting context — whether that means track days, circuit racing or spirited road riding — the slipper function addresses one of the fireblade's few remaining dynamic weaknesses. The improved closure-phase control in cornering also prevents the familiar tucking sensation that can arise when the clutch re-engages mid-corner, a detail that matters enormously at pace. Combined with the rotational mass reduction, the overall effect is a bike that steers more keenly, brakes more predictably and accelerates more crisply out of slow corners.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe STM FHN-S080 is engineered specifically for the Honda CBR 1000 RR across the full 2008 to 2019 model range. Fitment is direct; no modification to the crankcases or primary drive is required. Always verify your exact model year and variant prior to fitting.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2008\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2009\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2010\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2011\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2012\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2013\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2014\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2015\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2016\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2017\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2018\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR — 2019\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: STM\u003c\/li\u003e\n\u003cli\u003ePart number: FHN-S080\u003c\/li\u003e\n\u003cli\u003eType: Slipper clutch (antihopping clutch)\u003c\/li\u003e\n\u003cli\u003eFitment: Honda CBR 1000 RR (2008–2019)\u003c\/li\u003e\n\u003cli\u003eAntihopping mechanism: Patented ball-ramp system\u003c\/li\u003e\n\u003cli\u003eSpring type: Diaphragm spring\u003c\/li\u003e\n\u003cli\u003eWeight saving over OEM: approximately 0.7–0.8 kg\u003c\/li\u003e\n\u003cli\u003eOrigin: Italy\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STM","offers":[{"title":"Default Title","offer_id":53168705962250,"sku":"FHN-S080","price":1028.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FDU-S050_08381deb-7f1a-42a3-b281-a3dbf77f1989.png?v=1780811735","url":"https:\/\/inter-pace.com\/products\/stm-fhn-s080","provider":"Inter-Pace","version":"1.0","type":"link"}
