Bonamici Racing PSY1R Race Top Triple Clamp for Yamaha YZF-R9 (2025-2026)

Machined from a single billet of aerospace-grade aluminium and finished to exacting Italian race tolerances, the Bonamici Racing PSY1R upper triple clamp is the definitive front-end upgrade for the Yamaha YZF-R9. Where the standard unit flexes under hard braking and rapid direction changes, this CNC-milled race component delivers the rigidity and feedback precision that trackday riders and circuit competitors demand.

Key Features

• CNC-milled from solid high-tensile aerospace aluminium — no casting porosity, no compromise on dimensional accuracy
• Anodised surface treatment for outstanding corrosion and wear resistance, maintaining appearance and integrity under track conditions
• Titanium fork-clamp bolts included as standard, saving additional unsprung weight without sacrificing clamping force
• Designed without a standard ignition-lock mount (keyless race layout), freeing up space for data-logging and race-control electronics
• Approx. 0.275 kg — substantially lighter than the OEM triple clamp, reducing unsprung front-end mass for sharper fork response
• Developed from Bonamici's direct involvement in MotoGP and WorldSBK — race intelligence translated directly into a street-legal part number

Build Quality and Materials

Every PSY1R begins as a solid block of high-strength aluminium alloy. Multi-axis CNC machining removes material with surgical precision, leaving a component that fits the YZF-R9's fork legs without shimming or adjustment. Flex — the enemy of steering feel — is engineered out at the design stage rather than compensated for with geometry changes. The anodised finish is not merely cosmetic: it hardens the surface layer, resists the heat cycles seen on a race circuit, and keeps the part looking as purposeful after a season of trackdays as it did in the box.

Titanium fork-clamp bolts ship with every unit. Titanium offers a tensile strength comparable to steel at roughly half the weight, which matters when the goal is to strip every unnecessary gram from the front axle line. It is the kind of detail that distinguishes a part built for racing from one that merely looks the part.

Performance on Road and Track

The primary gain from a race triple clamp is steering communication. The YZF-R9 is already a precise machine, but the OEM upper clamp is engineered around comfort tolerances, legal requirements, and the necessity of carrying a conventional ignition barrel. Replacing it with the PSY1R removes that compromises: turn-in becomes more immediate, mid-corner corrections are transmitted more faithfully to the rider's hands, and braking stability under trail-braking into slow corners is noticeably improved. At high speed on a circuit, where small inputs carry large consequences, that clarity of feedback is not a luxury — it is a safety and pace advantage.

The keyless race design also means the top of the cockpit is uncluttered, giving free rein to mount a lap-timer, a GPS logger, or a quick-release windscreen bracket without routing around an ignition assembly that serves no purpose in a race environment.

Fitment and Compatibility

The Bonamici Racing PSY1R is designed and manufactured exclusively for the Yamaha YZF-R9 (2025–2026). It is a direct upper triple clamp replacement. Note that the race version does not accommodate a standard ignition barrel; confirm your YZF-R9 is configured for keyless or race use before fitting.
