When every tenth of a second counts at the track, the K-Bike EX01N eccentric rear hub delivers the precision-machined performance that serious Ducati Panigale V4 racing builds demand. Engineered from solid Ergal 7075 T6 aluminium and finished in a purposeful black, this lightweight hub replaces the OEM unit with a component built to motorsport standards — reducing unsprung weight and maintaining the exacting tolerances that the Panigale V4 platform deserves.
Key Features
- Precision-machined eccentric rear hub designed specifically for track and racing applications on the Ducati Panigale V4, V4 S and V4 R (2018–2024)
- Constructed from solid Ergal 7075 T6 — the aerospace-grade aluminium alloy prized in motorsport for its exceptional strength-to-weight ratio
- Lightweight construction reduces unsprung mass for sharper rear-end response and improved tyre contact under race conditions
- Supplied complete with internal spacer and bearings — a ready-to-fit racing assembly requiring no additional hardware
- Black anodised finish provides a discreet, technical aesthetic that complements the aggressive Panigale V4 bodywork
- Replaces OEM parts 75620131A and 75620171A with a motorsport-grade alternative
Ergal 7075 T6 — Motorsport Aluminium at its Best
Ergal 7075 T6 is the benchmark material for high-load, weight-critical racing components. Its tensile strength rivals many steel alloys while keeping mass to a minimum — exactly the balance required in the rear wheel assembly of a 200 bhp superbike being pushed hard through chicanes and braking zones. K-Bike machines the EX01N from solid billet, ensuring dimensional consistency and the kind of surface finish that speaks to genuine motorsport manufacturing expertise.
The black surface treatment adds corrosion resistance without adding weight, and the result is a component that sits perfectly alongside aftermarket swingarms, lightweight wheels and race-specification brake assemblies favoured by Panigale V4 track competitors.
Complete Racing Assembly
The EX01N is supplied as a complete unit — hub, internal spacer and bearings included. This means the installation process is clean and straightforward, with no need to source separate bearing kits or spacers. For trackday riders building a dedicated bike and for race teams assembling a fresh spare wheel, that completeness matters. The eccentric design allows chain tension adjustment within the swingarm, preserving the precise rear geometry that the Panigale V4 chassis is engineered around.
