Product: ABS plastic motorbike spoilers / winglets for Harley Softail Street Bob / Breakout FXBR FXBRS (2018–2022) Key benefits Reduced wind noise: Redirects airflow away from the rider to lower buffeting and audible wind turbulence at speed. Improved stability and downforce: Stabilizes airflow around the rear of the motorcycle to improve speed stability and increase rear downforce when riding fast. Lowprofile, sleek appearance: Compact, understated exterior and simple color scheme that complements the bike's lines without drawing attention. Main features Function: Motorcycle spoilers / winglets designed to improve airflow stability and downforce; effect becomes more pronounced at higher speeds (limited effect at low speeds). Material: Durable ABS plastic for a balance of impact resistance and lightweight performance. Design: Compact, lowprofile shape with a clean, simple color scheme to suit the Harley Softail aesthetic. Compatibility: Specifically made for Harley Softail Street Bob and Breakout FXBR and FXBRS models, model years 2018–2022. Performance notes Most effective during speed riding: The aerodynamic benefits increase with speed; riders will notice greater reduction in buffeting and improved rearend stability on highways and fast roads. Minimal effect at slow speeds: At city or stopandgo riding speeds the spoiler influence is limited, consistent with typical winglet behavior. Use scenarios Highway cruising: Reduce wind noise and improve longdistance comfort and stability on sustained speed runs. Performance or spirited riding: Increase rear downforce and airflow stability when running at higher speeds or during fast cornering. Gusty or crosswind conditions: Help maintain steadier handling when encountering crosswinds or turbulent airflow. What it solves Cuts rider fatigue caused by wind buffeting on long rides. Enhances confidence by improving rear stability at speed. Maintains the motorcycle's aesthetics while adding functional aerodynamic benefit. Compatibility reminder Intended for Harley Softail Street Bob and Breakout FXBR / FXBRS models from 2018 to 2022. Material and design details are aligned with these models' styling and fitment requirements.
