DescriptionThe whole story▼

When protection, aerodynamic performance and certified roadworthiness matter in equal measure, the Puig engine spoiler for the Ducati Monster 937 Plus (2021–2025) delivers on all three. Carrying ABE homologation KBA 30653 BS and full TÜV quality certification, this precision-engineered aero winglet is one of the few downforce spoilers in its class that can be fitted and ridden with complete legal confidence on public roads across Europe.

Key Features

  • ABE homologation KBA 30653 BS – fully road-legal in Germany and accepted across EU member states; no individual type approval required.
  • TÜV-certified quality standards ensure the spoiler meets rigorous independent safety and durability benchmarks before it reaches your bike.
  • Wind-tunnel validated aerodynamic geometry improves airflow management and contributes to enhanced stability at speed.
  • ABS construction with integrated UV-inhibiting surface treatment resists fading and chemical attack without requiring paint or additional finishing.
  • Impact-resistant design shields the lower engine area from road debris, stones, and minor impacts that would otherwise damage exposed components.
  • Lightweight at 572 g – the spoiler adds genuine aerodynamic and protective benefit with negligible effect on overall motorcycle mass.
  • Designed and manufactured in Barcelona; contoured specifically to follow the lines and volumes of the Monster 937 Plus for a factory-correct appearance.

Engineering & Build Quality

Puig developed the engine spoiler range at their Barcelona facility, using virtual wind-tunnel simulation to optimise the aero profile before a single physical prototype was cut. The outer shell is formed from acrylonitrile butadiene styrene (ABS) – a material chosen for its exceptional balance of rigidity, impact absorption and low weight. Rather than relying on a separate paint layer that can chip or peel, Puig applies a built-in surface treatment directly to the ABS during manufacture. This treatment resists UV degradation and chemical agents including fuel spillage, chain lubricant and road grime, keeping the finish intact without any owner maintenance.

Metal support brackets are fabricated from 2 mm steel with an anti-corrosion treatment, giving the mounting system the structural integrity to handle road vibration and incidental impacts over the long term. The entire assembly is engineered for straightforward installation, with paper-format step-by-step instructions included; a video tutorial is also available should you prefer a visual guide.

Aerodynamic Spoiler – Road & Track Rationale

On a naked motorcycle such as the Monster 937 Plus, the lower engine bay is exposed to buffeting airflow that creates aerodynamic drag and can introduce instability at motorway speeds or on fast, flowing roads. The Puig winglet redirects this airflow around the engine casings, reducing turbulence beneath the frame and contributing to a more planted, confidence-inspiring ride. While the primary engineering brief is aerodynamic improvement and lower-body protection, the spoiler's sport-focused silhouette also sharpens the Monster's visual attitude – most models in the Puig engine spoiler range include a sticker kit for further personalisation.

If your Monster 937 Plus is fitted with OEM or aftermarket accessories such as aftermarket exhausts or custom mudguards, please contact us before ordering to confirm there are no fitment conflicts with the spoiler.
