Hesterberg-Cad/Cam 8mm Bobbins / Swingarm Spools for BMW S1000RR K46 & K67 (2009–2026)

Machined from aerospace-grade aluminium 7075-T6, these Hesterberg-Cad/Cam swingarm spools bring genuine factory-quality construction to every BMW S1000RR K46 and K67 built between 2009 and 2026. At just 60 g the pair, they add precisely engineered 8 mm stand pick-up points to your swingarm without unnecessary mass — the kind of detail that separates a properly prepared trackday bike from everything else.

Key Features

• Aluminium 7075-T6 construction — the same high-strength alloy used in motorsport components — delivers exceptional rigidity at minimal weight
• 8 mm thread interface provides a secure, rattle-free seating for compatible rear paddock stands
• Factory-style finish integrates cleanly with the S1000RR's aggressive aesthetic at the swingarm
• Dedicated fitment engineered specifically for the K46 and K67 chassis — no adapters, no guesswork
• Supplied complete with two M8x30 mm bolts for a straightforward, tool-in-hand installation
• Applicable across the full 2009–2026 production run, covering both the original K46 and the revised K67 platform

Build Quality and Materials

Hesterberg-Cad/Cam produce these bobbins using CAD/CAM-guided machining processes that hold tight tolerances throughout. The choice of aluminium 7075-T6 is deliberate: this alloy offers a strength-to-weight ratio that far exceeds standard 6061 aluminium and holds up reliably under repeated stand loading in garage, workshop and paddock environments. The thread engagement is clean and consistent, so the M8x30 mm bolts torque down correctly every time without the risk of thread damage that cheaper cast alternatives carry.

The factory-style profile keeps the spools compact and unobtrusive against the swingarm. There is nothing superfluous here — every dimension has a purpose, and the result is a part that looks as considered as the bike it fits.

On the Road, in the Workshop and at the Track

Once fitted, these bobbins become one of the most frequently used contact points on your S1000RR. Tyre changes, chain lubrication and adjustment, brake pad inspection, tyre warmer sessions before a track outing — all of these tasks become noticeably more controlled and efficient when you have defined, rigid stand pick-up points. Attempting the same work without dedicated spools often means improvising with the paddock stand, which risks swingarm contact damage and wastes time.

For riders who attend trackdays regularly, clean swingarm spools are close to essential equipment. They allow quick, confident lifting of the rear wheel, keep the bike stable while work is carried out, and ensure it is ready to roll the moment the session calls for it. The 60 g weight penalty is negligible; the practical gain is immediate.
