The triple clamp is carved from a single piece of aeronautical aluminium — a grade chosen for its exceptional strength-to-weight ratio — rather than cast or pressed from lesser material. Every surface is then hard-anodised, creating a finish that is not merely cosmetic but structurally protective, sealing the aluminium against moisture ingress, track grime, and the micro-corrosion that degrades lesser parts over time. The included titanium fasteners extend that commitment to quality right through to the hardware.\u003c\/p\u003e\u003ch2\u003ePerformance and Handling\u003c\/h2\u003e\u003cp\u003eThe primary purpose of an aftermarket upper triple clamp is to eliminate the small but consequential amounts of flex inherent in a mass-produced OEM part. On the YZF-R9, the PSY4 creates a stiffer, more direct connection between the fork legs and the frame, which riders will notice immediately in fast direction changes and when carrying speed into corners. At track pace — where brake-diving forces and lateral loads are at their highest — the reduction in flex produces cleaner, more consistent front-end feel and greater confidence under hard braking. On the road, the same qualities translate to a more planted, communicative ride without harshness.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Bonamici Racing PSY4 is designed as a direct plug-in replacement for the Yamaha YZF-R9 upper triple clamp. No fork modification, additional machining, or fabrication is required. Installation uses the existing standard mounting points and can be completed in a few straightforward steps. Available in black anodised or silver anodised finish to suit your build aesthetic.\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha YZF-R9 — model years 2025 and 2026\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBonamici Racing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003ePSY4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent\u003c\/td\u003e\n\u003ctd\u003eUpper fork triple clamp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eAeronautical-grade aluminium, CNC-machined from solid billet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurface finish\u003c\/td\u003e\n\u003ctd\u003eHard-anodised (black or silver)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eapprox. 0.345 kg \/ 0.761 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFasteners included\u003c\/td\u003e\n\u003ctd\u003eHigh-quality titanium bolts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntended use\u003c\/td\u003e\n\u003ctd\u003eRoad and track\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eYamaha YZF-R9 (2025–2026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Bonamici Racing","offers":[{"title":"Black Anodised","offer_id":53168558145802,"sku":"PSY4","price":405.91,"currency_code":"EUR","in_stock":true},{"title":"Silver Anodised","offer_id":53168558178570,"sku":"PSY4_SI","price":405.91,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/2_240ec32d-a69a-49d6-96a6-a852a2abc2d1.png?v=1780808522","url":"https:\/\/inter-pace.com\/en-it\/products\/bonamici-racing-psy4-upper-fork-triple-clamp-yamaha-yzf-r9","provider":"Inter-Pace","version":"1.0","type":"link"}
