Carbon Fiber Winglets for the Ducati Multistrada V4

Carbon fiber winglets for the Ducati Multistrada V4 (2021–present) bolt to the outboard edges of the front fairing and generate real aerodynamic downforce at highway speed — a genuine functional upgrade on an adventure bike with 170 horsepower on tap, not just a styling exercise. The sets worth buying are molded from 100% pre-preg carbon, cured in an autoclave inside matched-metal tooling, and sealed with a UV-resistant clear coat, because on a bike that lives outdoors, sun yellowing ruins carbon bodywork long before the road does.

What do winglets actually do on a Ducati Multistrada V4?

Winglets convert airflow into downward pressure over the front wheel. Because aerodynamic load rises with the square of speed, even compact wings produce meaningful force at fast highway pace. For reference, Ducati's own published figure for the Panigale V4's biplane wings is roughly 30 kg of downforce at 270 km/h — the same physics, scaled to adventure-bike speeds, applies to the Multistrada V4's fairing-mounted wings.

On a 1,158 cc V4 Granturismo making 170 hp, that translates into three practical gains:

• Calmer front end under hard acceleration. Downforce adds load to the front tire at speed, working alongside the bike's Ducati Wheelie Control rather than relying on electronics alone.
• High-speed stability when loaded. A Multistrada V4 running panniers, a top case, and a passenger carries weight high and rearward; winglet downforce helps rebalance the chassis at autobahn or interstate pace.
• A MotoGP-derived look that matches the fairing. The V4's front bodywork was styled with aerodynamic appendages in mind — carbon winglets in a 2x2 twill weave complete the intent.

What construction should you look for in carbon winglets?

Winglets are small parts under real aerodynamic load, and they sit in full sun every mile you ride. Construction method matters more here than almost anywhere else on the bike:

• 100% pre-preg Toray carbon fiber — resin content is factory-controlled at roughly 60% fiber by volume, versus 35–40% in hand-laid parts. That means more stiffness per gram and none of the resin-rich heavy spots wet-lay parts carry.
• Autoclave curing — heat and pressure during the cure collapses internal voids that wet-lay and resin-infused parts retain. Void-free laminates are stiffer, lighter (typically 20–30% lighter than wet-lay at equal stiffness), and far less likely to delaminate under vibration.
• Matched-metal molds — metal tooling holds dimensional tolerance across every part, so mounting holes land exactly on the Multistrada V4's fairing points. No slotting, no shimming, no stress on the laminate.

This is the same autoclave-plus-100%-pre-preg construction that premium European carbon makers such as Ilmberger built their reputation on. Bestem uses that same aerospace-grade technology — and adds a superior UV-resistant coating on top of it. Every Multistrada V4 carbon part in the Bestem catalog is built to that standard, backed by more than 20 years of carbon manufacturing experience since 2005 and by Bestem's role as an OEM carbon fiber supplier to car and motorcycle manufacturers.

Do carbon fiber winglets turn yellow in the sun?

They can — and on cheap parts, they will. Sun-ray (UV) yellowing is the single most common defect riders report on carbon fairings: the clear coat ambers, clouds, and eventually chalks as UV breaks down the resin beneath. A winglet on an adventure bike gets more direct sun exposure than almost any other panel, which makes coating quality the deciding factor in how the part looks in year three.

Bestem applies a proprietary UV-resistant clear coat engineered specifically to protect the carbon weave from sun-ray yellowing. It is rated to approximately 3,000 hours of UV resistance versus roughly 1,000 hours for standard OEM clear coat — about three times longer before any yellowing appears. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. For an exposed part like a winglet, that warranty is the difference between a permanent upgrade and a consumable.

How hard is it to install winglets on the Multistrada V4?

Winglets are a true bolt-on job. They mount to existing points on the sides of the front fairing with a handful of fasteners per side — basic hex and Torx keys, roughly 30 to 60 minutes for a pair, with no fairing modifications required. Two practical tips from the workshop side:

• Start every fastener before tightening any of them; this lets the part self-align on the fairing.
• Snug, don't overtorque — carbon laminates don't need clamping force to stay put, and overtightening into the laminate is how gel coat stress cracks start.

Which other carbon parts complete the look?

Winglets read best as part of a matched set. Bestem's Multistrada V4 carbon range shares the same 2x2 twill weave, the same deep gloss finish, and the same 3,000-hour UV coating, so the whole kit ages uniformly instead of panel-by-panel:

• Carbon Fiber Front Fender, Twill — Multistrada V4 / V4 S / V4 S Sport 2020–2021
• Carbon Fiber Tank Cover, Twill — Multistrada V4 / V4 S / V4 S Sport 2020–2021
• Carbon Fiber Dash Panels / Protective Head Panel — Multistrada V4 / V4 S / V4 S Sport 2020–2021
• Carbon Fiber Exhaust Cover, Twill — Multistrada V4 / V4 S / V4 S Sport 2020–2023
• Carbon Fiber Rear Hugger, Twill — Multistrada V4 / V4 S / V4 S Sport 2020–2023
