DescriptionThe whole story▼
Rooted in Italian race-craft and shaped by seasons of Superbike competition, the Carbonin SBK tank extension for the BMW S1000RR K67 is a purpose-built carbon fairing component that refines the silhouette of the K67 generation while delivering genuine aerodynamic gains at speed. Available in two extension lengths — 2 cm (CB4405) and 4 cm (CB4406) — it lets you tailor the tank area to suit your riding position, bodywork package and circuit demands.
Key Features
- Precision-laid high-grade carbon construction: inherently stiff, exceptionally light, and resistant to fatigue under repeated track loads.
- Two extension options — 2 cm pad (CB4405) for a subtle aerodynamic refinement, 4 cm pad (CB4406) for more substantial airflow management and additional stability at high speed.
- Designed exclusively for the BMW S1000RR K67 (2019–2022), ensuring an accurate, factory-close fit with the existing fairing architecture.
- Improves front-end stability and wind protection by extending and smoothing the tank-to-fairing transition zone.
- Superbike-grade quality: engineered to the same standards Carbonin supplies to professional racing paddocks worldwide.
Design, Finish and Heritage
Carbonin's reputation was forged in the World Superbike paddock, where reducing grams and managing airflow are not cosmetic concerns but competitive imperatives. The SBK tank extension reflects that lineage directly: the carbon weave is left visible beneath a clear protective finish, giving the part the honest, unadorned look that marks genuine race bodywork rather than a styled replica. Every piece is formed in high-quality carbon fibre, balancing rigidity with low mass — qualities that matter equally whether the S1000RR is on a circuit or cutting through a demanding mountain road.
The two available pad depths exist because no two riding styles or bodywork configurations are identical. The 2 cm extension offers a clean visual extension of the tank line with a moderate aerodynamic benefit, while the 4 cm version produces a more pronounced rearward shelf that assists in routing air around the rider at higher velocities and contributes to front-end composure under full-throttle commitment.
Track Performance and Aerodynamics
At the speeds the S1000RR K67 is capable of generating, even small improvements in aerodynamic coherence translate into measurable stability gains. By bridging and extending the junction between tank and fairing, the Carbonin tank extension discourages turbulent airflow in a zone that is ordinarily disruptive. The result is a more settled, planted feel at the front end — an advantage that is immediately perceptible when riding at the limit on long, fast straights or high-speed sweepers.
Installation Note
This is not a plug-and-play accessory. Fitting the tank extension requires precise alignment and professional installation to achieve the correct panel gap, aerodynamic seal and structural integrity. Inter-Pace recommends having this part installed by a qualified technician or race preparation specialist familiar with carbon fairing assembly.
