Fullsix Carbon Rear Mudguard "STK" BMW S1000RR K46 (2009-2018) – ABE Approved

Crafted from aerospace-grade autoclave carbon fibre with zero filler materials or mixed weaves, the Fullsix "STK" rear mudguard represents the upper tier of carbon bodywork available for the BMW S1000RR K46. Every panel leaves the Fullsix facility with a flawless layup, tight fibre alignment, and the kind of surface finish that sets it apart from budget alternatives — whether you choose the deep-gloss lacquer or the refined matte coat.

Key Features

• 100% autoclave-cured carbon fibre construction — no mixed fibres, no compromises in structural integrity or surface quality
• Available in 200 Plain weave (closely mirrors the BMW OEM visual language) or 245 Twill weave (deeper motorsport pattern for a more distinctive racing aesthetic)
• Plug-and-play fitment: replaces the stock BMW S1000RR K46 rear mudguard directly, with no cutting, drilling, or modifications required
• Includes ABE (Allgemeine Betriebserlaubnis) German type approval — fully road-legal without any additional registration
• UV-stable resin system resists yellowing and material fatigue through prolonged exposure to sun, rain, and road debris
• Reduces unsprung and overall rear-end mass compared to the OEM plastic unit, contributing to sharper handling response

Build Quality and Premium Materials

Fullsix has built its reputation on one principle: no shortcuts in the layup room. The "STK" rear mudguard is produced using pre-preg carbon cloth cured under controlled autoclave pressure and heat, a process that eliminates voids in the resin matrix and produces a part with a consistently high fibre-to-resin ratio. The result is a panel that is measurably stiffer and lighter than equivalent hand-laid pieces, with a surface that requires no further finishing work straight from the box.

The 200 Plain weave option uses a fine, uniform grid pattern that integrates naturally with the S1000RR's visual lines — an understated upgrade that reads as OEM-quality from a distance and reveals its premium character up close. The 245 Twill weave presents the classic diagonal carbon pattern that has become synonymous with high-end motorsport components, offering a bolder, more expressive look for riders who want the upgrade to make a statement.

Both finishes — gloss and matte — are applied over the same base laminate. The gloss version is sealed under multiple coats of high-clarity lacquer for a mirror-like depth. The matte version uses a satin-clear topcoat that eliminates reflections while retaining the texture and definition of the weave beneath.

Road and Track Performance

The mudguard's primary function is unchanged from the OEM part: it shields the swingarm, rear suspension linkage, and underside of the tail section from water ingress, road grit, and tyre spray. What changes is the weight of the component doing that job. The carbon construction sheds mass from the rear of the motorcycle, a location where reducing rotating and unsprung weight has the most direct effect on agility and steering precision. On road or track, the S1000RR responds more freely through direction changes when unnecessary mass has been removed from the tail end.

Motorsport-tested under demanding race conditions, the Fullsix laminate maintains its geometry and integrity where lesser carbon parts may flex, chip, or delaminate. The UV- and weather-resistant resin system means the part performs equally well on a wet British A-road and under the full sun of a European circuit.
