Forsaken Motorsport Linear Suspension Linkage – BMW S1000RR K46 (2015–2018)

Developed exclusively for the BMW S1000RR K46 (2015–2018), the Forsaken Motorsport linear suspension linkage transforms the rear end's progressive rate into a far more predictable, linear response — giving track-focused riders the consistent traction and power delivery they need to push harder, lap after lap.

Key Features

• Converts the stock progressive suspension rate to a linear curve, delivering noticeably improved traction and drive out of corners.
• 35% stiffer than the original BMW linkage, dramatically reducing flex and deformation under hard braking and acceleration loads.
• CNC-machined in-house at Forsaken Motorsport in Canada on a Haas VM3 from solid billet aluminium — precision that shows in every dimension.
• Fully compatible with the stock spring, yet easily adapted to an aftermarket spring to suit individual rider preference and track conditions.
• Valve timing remains adjustable so you can fine-tune damping to take full advantage of the flatter progressive rate.
• Supplied with new BMW bearings; original bolts, sleeves and seals are reusable, keeping installation straightforward.

Performance on Track

The factory S1000RR K46 linkage uses a progressive rate that works acceptably across a wide range of road conditions, but at the limit on circuit it can introduce an inconsistency in rear-end feel that costs both confidence and lap time. By linearising that rate, the Forsaken Motorsport linkage gives your shock absorber a consistent, calculable input throughout the stroke. The result is a rear end you can lean on: sharper corner entry, earlier power application, and a more neutral balance through fast direction changes.

The 35% increase in structural rigidity over the OEM part means energy is transmitted rather than absorbed by the linkage itself. Combined with the retained valve-timing adjustability, the rider can dial in precisely the amount of support they want — whether that is a plush setup for a technical circuit or a stiffer, more reactive platform for high-speed tracks.

Construction & Finish

Every component is machined from a solid aluminium billet using a Haas VM3 vertical machining centre at Forsaken Motorsport's own facility in Canada. This in-house production process means tolerances are held to the same standard batch after batch, and quality is never delegated. Currently available in black anodised finish only — a hard, corrosion-resistant surface that stands up to the chain oil, heat and road debris that characterise real-world and track use alike.

Fitment & Compatibility

Designed and manufactured specifically for the BMW S1000RR K46, model years 2015, 2016, 2017 and 2018. Not compatible with pillion or two-up riding — for solo use only.
