DescriptionThe whole story▼

When every gram and every tenth of a second matters, the Fullsix Carbon Fuel Tank for the BMW S1000RR K67 is the component that separates a race-prepared machine from a stock one. Built using Autoclave Composite Monocoque (ACM) technology in genuine 245 Twill carbon fibre, it cuts tank weight from 2,230 g down to 1,100 g — a reduction of over 50 % — while simultaneously adding 0.5 litres of usable fuel capacity over the OEM unit.

Key Features

  • Over 50 % weight saving versus stock: 1,100 g versus 2,230 g OEM, for sharper turn-in, reduced unsprung mass influence and improved overall agility on track.
  • One-piece ACM monocoque construction eliminates the seam wear that can cause leaks on two-piece tanks, delivering maximum structural integrity and safety under racing conditions.
  • Genuine 245 Twill carbon fibre — UV-resistant, weather-resistant and extremely durable, with a weave that is as purposeful aesthetically as it is structurally.
  • Direct OEM replacement geometry: fits the BMW S1000RR K67 (2019–2026) without drilling, cutting or modification — true plug-and-play installation.
  • Available in Glossy, Matt or Raw carbon finishes and in 245 Twill weave, allowing teams and privateers to match their livery requirements precisely.
  • Technology derived directly from World Superbike competition, refined in the most demanding racing environments.

ACM Technology and Build Quality

Fullsix's Autoclave Composite Monocoque process subjects each tank to elevated pressure and temperature inside an autoclave, forcing out air pockets and consolidating resin uniformly throughout the carbon laminate. The result is a void-free, homogeneous structure with a fibre-to-resin ratio that maximises stiffness and minimises mass — qualities impossible to replicate with hand-laid or vacuum-bagged wet lay-up methods. The single-piece monocoque design means there is no internal joint, no bonded seam and no potential failure point between two shells, which is precisely why this construction method is preferred at the front of the grid.

Track Performance and Handling Gains

Reducing centrally mounted mass by over 1,100 g has a disproportionate effect on chassis dynamics. With the Fullsix tank fitted, the S1000RR K67 responds more crisply to rider input, requiring less countersteering force and allowing later, more confident braking. The additional 0.5-litre capacity is a meaningful advantage in endurance sprint formats where avoiding an extra fuel stop can decide a result. The tank integrates directly with the OEM fuel system, pump, sender and filler cap hardware, so installation is straightforward even under paddock conditions.
