Puig Downforce Winglets Spoiler for Yamaha YZF-R3 (2015-2018) – Part 3171

Drawn directly from WorldSBK-derived aerodynamic research, the Puig Downforce Sport Winglets (part 3171) bring genuine racing-grade downforce to the Yamaha YZF-R3 (2015-2018). Developed in collaboration with data and insights from the Kawasaki Racing Team's WorldSBK programme, these winglets transform the R3's aerodynamic profile for riders who demand more from every corner exit and straight.

Key Features

• Generates up to 6 kg of downforce at speed, improving front-end traction and reducing the risk of front-wheel lift under hard acceleration.
• Anti-wheelie effect keeps the front wheel planted during aggressive acceleration, enabling cleaner, more consistent power delivery out of slow corners.
• Minimises shimmy and lateral instability at high speeds, giving the rider greater confidence and a more planted front-end feel.
• Race-use optimised design — shaped and validated against real WorldSBK test data from the Kawasaki Racing Team programme.
• Available in black or red to complement the R3's sharp, aggressive styling.
• Robust, durable construction engineered to withstand the extreme loads of track use session after session.

WorldSBK-Proven Aerodynamic Technology

Puig developed the Downforce Sport range using test data gathered during the Kawasaki Racing Team's WorldSBK campaign — a programme where marginal aerodynamic gains translate directly into lap-time reductions. The 3171 winglets apply the same principles to the Yamaha YZF-R3 platform: additional downforce over the front axle reduces tyre slip under braking and acceleration, while the anti-shimmy geometry damps lateral oscillation that can unsettle the chassis mid-corner. The result is a motorcycle that feels substantially more planted and predictable at the limit, precisely where confident riding matters most.

Track Application

These winglets are designed and rated for race use. Fitted to the R3's fairing, they work most effectively at circuit speeds where aerodynamic forces are large enough to deliver measurable chassis benefit. Track-day riders and club racers running the YZF-R3 in class racing will find the additional front-end load especially valuable on high-speed circuits and during repeated hard-braking zones.
