DescriptionThe whole story▼
Shaving nearly 3 kg from the rear of your BMW S1000RR K67 is not a small gain — it is the kind of mass reduction that reshapes how a superbike rotates, transitions and drives out of corners. The Fullsix Carbon Monocoque Tail Section is a fully self-supporting structure engineered exclusively for track and racing use, replacing the factory aluminium subframe and rear bodywork assembly with a single, autoclave-cured 245 Twill carbon piece that weighs just 1,620 g against the OEM unit's 4,520 g.
Key Features
- Dramatic weight saving: OEM aluminium assembly 4,520 g versus Fullsix monocoque carbon 1,620 g — a reduction of almost 2,900 g from the rear of the bike.
- Self-supporting monocoque construction eliminates the factory aluminium subframe entirely, concentrating mass reduction where it matters most for agility and handling.
- Autoclave-manufactured from 100% carbon fibre — no mixed fibres, no compromises in structural integrity.
- 245 Twill weave delivers the deep, motorsport-grade visual texture associated with top-tier racing machinery.
- Direct 1:1 replacement for the OEM part — no modifications to the frame or mounting points required.
- Available in Glossy, Matte or Raw finish, with Raw suited to custom paint or livery preparation.
- UV-stable resin system resists yellowing and material fatigue across extended track seasons.
Monocoque Design — Why It Changes the Ride
A conventional carbon tail unit sits over the original aluminium subframe, replacing only the outer bodywork. The Fullsix monocoque approach goes further: the carbon structure itself carries the load, removing the subframe completely. The result is a lower polar moment of inertia at the rear of the machine, which translates directly into faster direction changes, more neutral mid-corner balance and improved drive traction as the rear steps into line sooner under acceleration.
On a circuit where lap times are decided by tenths, the combination of mass reduction and improved weight distribution gives the S1000RR K67 a measurably sharper character without any suspension retuning required at the point of fitment.
Finish Options
The 245 Twill weave is offered in three surface treatments to suit different racing and aesthetic requirements. The Glossy finish presents a deep, lacquered appearance that highlights the carbon weave under pit-lane lighting. The Matte finish delivers the aggressive, understated look common on current World Superbike machinery. The Raw finish leaves the surface uncoated, ready for teams and riders who wish to apply their own livery, team colours or custom clear coat.
Fullsix Carbon — Racing Pedigree
Fullsix has built its reputation by supplying carbon components to professional racing teams at the highest levels of the sport. Every piece is manufactured using autoclave processing — the same technique used in aerospace and MotoGP — to achieve a consistent, void-free laminate with the highest possible strength-to-weight ratio. Fit and finish are developed against OEM mounting points, so integration is seamless and installation straightforward.
Important Notice
This component is designed and approved for closed-circuit racing use only. It does not carry road type-approval (no ABE / EC type approval) and must not be fitted to any motorcycle used on public roads.
