IMA Special Parts Racing Top Yoke for BMW S1000RR K46 (2009–2018)

A precision-engineered top yoke that transforms the everyday riding experience on your BMW S1000RR K46, the IMA Special Parts Racing unit delivers sharper steering response and improved braking stability whether you are threading through traffic on a Sunday morning or chasing lap times at the weekend. Developed with FEM (Finite Element Method) analysis and machined from 7075 Ergal aluminium, it offers a tangible upgrade in feel and feedback without demanding a full track-day setup to appreciate the difference.

Key Features

• FEM-analysed construction ensures the yoke handles extreme braking and cornering loads without flex or fatigue
• 7075 Ergal aluminium provides an exceptional strength-to-weight ratio — ultralight yet more rigid than standard cast components
• Adjustable offset from 24 mm to 32 mm lets you dial in steering geometry to match your riding style, tyre choice or circuit layout
• Titanium fasteners throughout keep unsprung weight to a minimum while offering outstanding corrosion resistance
• Direct fitment to BMW S1000RR K46 (2009–2018) — no modification required
• Improved braking stability gives greater confidence under hard deceleration, on road or track alike

Build Quality and Everyday Usability

IMA Special Parts designed this top yoke to be as relevant for the road-focused S1000RR owner as it is for the committed trackday rider. The 7075 Ergal aluminium billet construction resists the knocks and vibrations of real-world use, while the anodised finish holds up against brake fluid, chain lube and the general abuse a high-performance streetbike accumulates over time. The adjustable offset range of 24–32 mm means you can soften the steering for long road trips or sharpen it up for a circuit without purchasing a different yoke entirely — genuine versatility that repays the investment across every ride.

Performance and Handling Gains

The FEM development process identifies and eliminates unwanted flex in the yoke structure, which translates directly into more precise fork behaviour under braking and through corner entry. Riders typically notice a more immediate front-end feel and a reduction in the vagueness that can affect the standard unit over time. Titanium bolts replace heavier steel hardware at every fastener point, contributing to a marginal but meaningful reduction in mass exactly where it matters most — high on the chassis, close to the steering axis.

Fork Diameter — Important Note

The IMA Special Parts Racing top yoke is manufactured to accommodate different fork tube diameters. Please state your fork diameter clearly in the order notes at checkout to ensure the correct bore is supplied.
