DescriptionThe whole story▼

Born from Bonamici Racing's deep roots in circuit competition, the PSB3 Street top yoke brings that same engineering philosophy to the BMW S1000RR K67. Machined from high-tensile aluminium and designed as a direct, modification-free replacement, it sharpens steering precision and chassis feedback on both track days and demanding road rides — giving you the feel of a race-prepared front end without compromising everyday usability.

Key Features

  • High-tensile aluminium construction delivers an exceptional strength-to-weight ratio, reducing unsprung mass at the critical steering axis.
  • Race-derived geometry engineered specifically for the BMW S1000RR K67 (2023-2026) for immediate, precise steering response.
  • Street version pre-configured with a steering plate for the key barrel, simplifying installation and retaining OEM ignition integration.
  • Bolt-on fitment — no modifications to frame or forks required, making installation straightforward for experienced home mechanics and workshops alike.
  • Available in anodised black or anodised silver to complement your S1000RR's livery.
  • 100% Made in Italy by a manufacturer with decades of Superbike and World Supersport championship pedigree.

Track Roots, Road Refinement

Bonamici Racing developed the PSB3 using data gathered from top-level Superbike competition. The result is a top yoke whose wall sections and spoke profiles are calculated to resist the torsional loads produced by hard braking and aggressive corner entry — the moments when a stock yoke's flex is most apparent. On a track day, that translates to a front end that communicates more clearly through the bar, allowing later braking points and more confident turn-in. On the road, the same rigidity smooths out the nervous chatter that can appear on broken surfaces at speed.

Precision Fit for the K67 Generation

Every dimension of the PSB3 is drawn from the K67 platform's fork tube diameter, steering stem taper and clamp spacing. The result is a part that installs without shimming or adapter plates and sits flush against the upper fork legs, preserving the factory steering geometry unless you choose to adjust it. The integrated key-barrel plate means the OEM ignition switch drops straight in — a detail that separates this street-specific variant from Bonamici's pure track offerings.
