CNC Racing Rear Sprocket Carrier Ducati Panigale V4 / V4S / V4R (2025-2026) FC253

Machined from solid billet aluminium and finished with a hard anodised surface, the CNC Racing FC253 rear sprocket carrier sets a new benchmark for drivetrain quality on the Ducati Panigale V4, V4S and V4R for model years 2025 and 2026. Every edge, recess and bolt face is the product of precision CNC milling — not casting — ensuring dimensional accuracy and structural integrity that production hubs simply cannot match.

Key Features

• Solid billet aluminium construction, CNC-milled throughout for maximum strength and long-term durability
• Hard anodised finish available in black (FC253B), gold (FC253G) or red (FC253R) — corrosion-resistant and track-proven
• Grade 5 titanium bolts included as standard, delivering exceptional tensile strength at a fraction of the weight of steel hardware
• Bearings and bushings are pre-installed at the factory for straightforward plug-and-play installation as a direct hub replacement
• Compatible with both the original Ducati sprocket rings and CNC Racing Ergal sprocket rings, giving full flexibility when tuning gearing

Build Quality and Materials

The FC253 is the kind of component that earns its place on both road-registered Panigales and full race builds. The raw material is a high-grade light alloy billet, chosen for its strength-to-weight ratio. CNC milling removes every unnecessary gram while preserving the wall thicknesses and bearing seat geometry that keep the drivetrain running true under the sustained high-torque conditions a Panigale V4 R can generate at the rear wheel.

The anodised surface treatment penetrates the aluminium rather than sitting on top of it, meaning it resists chipping from chain spray and debris far better than paint or powder-coating. Grade 5 titanium bolts — the same specification used in aerospace fastener applications — are threaded and torqued to spec before the carrier leaves the factory, so installation requires no hunting for compatible hardware.

Installation and Compatibility with Sprocket Rings

Because the bearings and bushings arrive pre-installed, fitting the FC253 is a direct replacement for the original Ducati hub. There is no pressing, no specialist tooling beyond a standard torque wrench, and no need to source separate bearing kits. Once the carrier is on the wheel, both the OEM Ducati sprocket rings and the CNC Racing Ergal-series rings bolt straight on, which means the FC253 works equally well whether you are running standard gearing or experimenting with different sprocket ratios for specific circuits or road use.

Fitment and Compatibility

The CNC Racing FC253 rear sprocket carrier is engineered specifically for the following models:

• Ducati Panigale V4 — model years 2025 and 2026
• Ducati Panigale V4S — model years 2025 and 2026
• Ducati Panigale V4R — model years 2025 and 2026
