DescriptionThe whole story▼
Engineered in Barcelona from premium-grade ABS and precision-formed metal hardware, the Puig D12 side spoilers bring genuine aerodynamic downforce to the Kawasaki Z1100 and Z1100 SE (2026). This is not a styling exercise — the D12 line was conceived with one purpose: to maximise aerodynamic performance on high-performance naked motorcycles, and every dimension of the design reflects that ambition.
Key Features
- Innovative double-wing layout with separate aerodynamic surfaces divided by a lateral spoiler, channelling airflow upwards for increased downforce without compromising the overall drag coefficient
- Generates up to 4.4 kg of downforce on the front axle, delivering a measurable anti-wheelie effect and confident high-speed composure
- Anti-shimmie performance: the aerodynamic load stabilises the front end on long straights, reducing the nervous weave that plagues fast naked bikes
- Improved braking stability and more precise behaviour during direction changes — the downforce spoiler keeps the front axle planted under hard deceleration
- Manufactured from acrylonitrile butadiene styrene (ABS) with rounded profile edges for enhanced rider safety and a clean, purposeful aesthetic
- Mounted on 2 mm metal brackets with a textured black finish — robust, rattle-free and resistant to road vibration
- Homologated to ABE KBA 31948 SP W. NAKED SIDE and compliant with German TÜV quality standards, making road-legal fitment straightforward
Double-Wing Aerodynamic Architecture
The defining feature of the D12 winglet system is its carefully calculated dual-surface geometry. Unlike single-plane side spoilers, the D12 divides its working area into two distinct aerodynamic surfaces separated by a lateral spoiler element. The angle of each surface has been studied to strike an optimal balance between peak downforce generation and overall stability, so the aero kit enhances performance without introducing unwanted drag or unpredictable handling characteristics. The result is a motorcycle wing that functions as a genuine performance component rather than a cosmetic addition.
Premium Construction, Barcelona Built
Puig designs and manufactures the D12 range entirely in-house at their Barcelona facility, where decades of motorsport experience inform every production decision. The spoiler bodies are moulded from acrylonitrile butadiene styrene — a material chosen for its excellent rigidity-to-weight ratio, resistance to UV degradation, and consistent dimensional stability across a wide temperature range. The rounded profile finish is not merely aesthetic; it eliminates sharp edges that could cause injury during a fall or routine maintenance, meeting the safety criteria demanded by TÜV certification. At 682 g the complete set adds meaningful aerodynamic benefit without noticeable mass penalty. The 2 mm metal mounting brackets arrive with a textured black finish that resists corrosion and blends unobtrusively with the Z1100's aggressive naked silhouette.
On the Road and on Track
Whether you are pushing the Z1100 through high-speed motorway sections or exploring its limits on a closed circuit, the D12 downforce spoilers work continuously to keep the front tyre loaded. The anti-wheelie effect is particularly noticeable during hard acceleration out of slower corners, while the anti-shimmie benefit becomes apparent at licence-threatening speeds where naked bikes are most susceptible to front-end instability. Braking stability — arguably the most safety-critical benefit — means you can carry speed deeper into corners with greater confidence that the front axle will remain settled.
Installation requires no specialist mechanical knowledge. The package includes clear instructions, and supplementary guidance is available online. Before fitting, please review the ABE KBA 31948 SP W. NAKED SIDE carefully to confirm this part is approved for use on your specific motorcycle.
