DescriptionThe whole story▼
Built for the track and refined for the road, the CNC Racing TSB21 is a race-grade carbon fuel cap engineered exclusively for the Ducati Panigale V4, V4S and V4R (2025-2026). Autoclave-manufactured from 100% carbon fibre with a plain-weave structure, it delivers the weight savings and visual precision that serious racing programmes demand.
Key Features
- Autoclave-cured 100% carbon fibre construction — maximum strength-to-weight ratio for track-focused builds
- Available in gloss (TSB21K) or matte (TSB21Y) carbon finish to suit your Panigale's livery
- Inner shell machined from Ergal aluminium with a hard-anodised surface — scratch-resistant even under repeated pit-lane refuelling
- Plug-and-play fitment replaces the OEM tank flange cover with zero modification required
- Fully modular: choose your insert separately — TSU02 Fast Open Racing plug or TSU01 Key Lock plug for road use
- Precision CNC Racing aesthetics that complement the Panigale V4 series' factory race styling
Track Performance, Pit-Lane Ready
At circuit level, every gram and every second counts. The TSB21's autoclave carbon fibre shell is produced using the same process applied in professional motorsport — high pressure and elevated temperature yield a component that is both exceptionally rigid and ultralight. The hard-anodised Ergal inner shell withstands the rigours of rapid refuelling in race conditions, resisting the scratches and scuffs that accumulate during a full track day. The plug-and-play design means changes in the pit lane are fast and tool-minimal, keeping downtime to an absolute minimum.
Versatility: Racing or Road
The TSB21's modular system lets you configure the cap exactly as your riding demands. On track, pair it with the TSU02 Fast Open Racing plug for rapid access during refuelling stops. For road riding or track days where regulations require a lockable cap, the TSU01 Key Lock plug is available separately, transforming the TSB21 into a fully street-compliant solution. Both inserts integrate seamlessly into the same carbon shell.
