DescriptionThe whole story▼
Puig's D12 winglet series brings genuine aerodynamic engineering to the Kawasaki Z900, delivering measurable downforce and real-world stability gains without demanding any specialist mechanical skill to fit. Developed and manufactured entirely in Barcelona, these side spoilers are a practical, confidence-building upgrade for riders who want sharper everyday performance on a naked bike.
Key Features
- Innovative double-wing design with separate surfaces divided by a lateral spoiler channels airflow upward, generating up to 4.4 kg of downforce on the front axle without inflating the overall aerodynamic drag coefficient.
- Anti-wheelie effect and high-speed straight-line stability (anti-shimmie) mean the Z900 stays planted and predictable whether you are cruising a motorway or pushing harder on a fast A-road.
- Improved braking composure and directional-change behaviour translate directly into greater rider confidence during everyday riding and spirited weekend runs alike.
- Rounded edge profile on every surface satisfies both safety requirements and aesthetic expectations — no sharp corners to catch clothing or cause concern in a minor tumble.
- Complies with German TÜV quality standards and carries ABE homologation (KBA 31948SP W.NAKED SIDE), confirming road-legal use on qualifying motorcycles.
- Simple bolt-on installation via 2 mm textured black metal brackets — no modification, no special tools, fully reversible.
Construction and Design
Each D12 winglet is moulded from acrylonitrile butadiene styrene (ABS), a material chosen for its combination of rigidity, impact resistance and light weight. The paired set tips the scales at just 482 g, so the aerodynamic gain costs virtually nothing in added mass. The bracket system uses 2 mm steel hardware with a satin-textured black finish that sits cleanly against the Z900's bodywork without looking afterthought-ish.
The angle of each wing surface has been studied extensively by Puig's Barcelona engineering team to strike the best balance between downforce generation and drag penalty. The result is a spoiler that works with the Z900's existing aerodynamic profile rather than fighting it — a detail that matters significantly on a naked motorcycle where airflow management is already a challenge.
Everyday Usability and Value
Unlike track-only aero kits that compromise road manners, the D12 is tuned for the conditions most Z900 riders actually encounter: motorway overtakes, fast bends, firm braking points, and the sort of directional changes a twisty B-road demands. The anti-shimmie characteristic is particularly valuable on longer rides where fatigue can make a wandering front end feel unsettling. Installation follows straightforward instructions included in the package — or available online — meaning you can be out riding the same afternoon you receive the parcel.
