DescriptionThe whole story

When lap times matter and precision is non-negotiable, the Bonamici Racing PSY1R race top yoke delivers the steering response and chassis rigidity that the Yamaha YZF-R1/M demands at its limit. Engineered specifically for track use across the RN32, RN49 and RN65 generation R1 and R1M (2015–2026), this upper fork bridge is a direct, bolt-on performance upgrade developed and manufactured entirely in Italy.

Key Features

  • Improves steering precision and front-end feel under hard braking and corner entry — exactly where tenths are won and lost on track.
  • Machined from high-strength aluminium billet for maximum rigidity with minimal weight penalty over the stock item.
  • Available in anodised black or anodised silver to complement the R1/M's aggressive race aesthetic.
  • Direct, no-modification fitment across the full RN32, RN49 and RN65 platform (2015–2026).
  • 100% Made in Italy — Bonamici Racing's hallmark of competition-grade quality and finish.
  • Race-version: the steering lock bracket plate is not included, keeping the assembly clean and track-focused.

Track-Proven Design

The PSY1R is Bonamici Racing's race-specification upper yoke — a component that sits at the very heart of the R1's steering geometry. By replacing the OEM top yoke with a purpose-built aluminium race unit, riders gain a measurably more direct connection between handlebar input and front tyre response. The stiffer, more precisely machined interface reduces flex under the aggressive lateral loads generated at race pace, translating into greater confidence when trail-braking deep into corners and holding a tighter line on exit.

The anodised finish is not merely cosmetic — it protects the aluminium from corrosion and wear across a full season of track days, sprint races and endurance events. Whether the choice is anodised black for an understated, factory-race look or anodised silver for a classic Italian motorsport aesthetic, the quality of execution is identical.

Fitment & Compatibility

This race top yoke is a precise fit for the following Yamaha models and type codes:

  • Yamaha YZF-R1 RN32 (2015–2019)
  • Yamaha YZF-R1M RN32 (2015–2019)
  • Yamaha YZF-R1 RN49 (2020–2023)
  • Yamaha YZF-R1M RN49 (2020–2023)
  • Yamaha YZF-R1 RN65 (2024–2026)
  • Yamaha YZF-R1M RN65 (2024–2026)

No modifications are required for installation. Note: the steering lock bracket plate is not included in this race version — this is standard practice for dedicated track builds where the steering lock assembly is removed.
