Forsaken Motorsport Linear Suspension Linkage for BMW S1000RR K46 (2009–2014)

Forsaken Motorsport's linear suspension linkage for the BMW S1000RR K46 transforms the factory's progressive rear suspension rate into a far more predictable, linear response — delivering measurably better traction and more consistent power transfer on both road and track. Machined in-house at Forsaken Motorsport's Canadian facility and finished in black anodised aluminium, this is a piece of precision engineering that speaks for itself before it ever touches the bike.

Key Features

• Converts the stock progressive suspension rate to a linear characteristic, improving traction and rear-end feedback through all phases of a corner.
• CNC-milled from a solid aluminium billet on a Haas VM3 machining centre at Forsaken Motorsport's own facility in Canada — no outsourced manufacture, no compromise on tolerances.
• 35% stiffer than the original BMW linkage, minimising flex and deflection under hard braking and acceleration loads.
• Compatible with the standard spring; valve settings can be adjusted to take full advantage of the flatter progressive rate, or the spring can be swapped to suit individual rider preference.
• Supplied complete with new BMW bearings — original bolts, sleeves and seals are retained, keeping installation straightforward.
• Anodised black finish: corrosion-resistant, visually purposeful, and consistent with the understated aesthetic Forsaken Motorsport is known for.

Design, Finish and Heritage

Forsaken Motorsport has built its reputation on parts that earn their place on serious machines. Every linkage leaves their Canadian workshop having been cut from a single billet of aluminium on a Haas VM3 — a mill chosen for its rigidity and repeatability, not convenience. The black anodised finish is not cosmetic padding; it protects the alloy against the road chemicals and track debris that an exposed suspension component inevitably encounters.

The geometry itself has been designed with a single purpose: to remove the ambiguity that the factory progressive rate introduces at the limit. Where the stock linkage softens progressively as the shock is compressed, Forsaken's linear alternative keeps the rate consistent throughout the stroke. The result is a rear end that responds predictably to throttle inputs, holds its line under trail-braking, and communicates clearly through the seat — qualities that matter whether you are chasing lap times or simply want a chassis you can trust on a fast public road.

Adjustability and Setup

The linear linkage does not demand an entirely new suspension setup. The standard BMW spring remains compatible and is a sensible starting point. Once the linkage is fitted, damping valving — both compression and rebound — should be revisited to suit the now-linear rate; Forsaken recommend using the flatter progressive characteristic as an opportunity to fine-tune rather than simply replace settings wholesale. Riders seeking a more bespoke spring rate will find the unit equally accommodating of aftermarket options.

Fitment and Compatibility

Designed and manufactured specifically for the BMW S1000RR K46 covering model years 2009, 2010, 2011, 2012, 2013 and 2014. Not compatible with any other chassis. For single-rider use only — pillion or passenger operation is not supported with this linkage fitted.
