<p><img decoding="async" loading="lazy" src="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-002.jpg" alt="" width="827" height="605" class="aligncenter size-full wp-image-90166" srcset="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-002.jpg 827w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-002-300x219.jpg 300w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-002-768x562.jpg 768w" sizes="(max-width: 827px) 100vw, 827px" /></p>
<p>何謂「腿部定風翼」？這項裝置最初出現在Aprilia RS-GP賽車上，隨後在2025年底推出的限量版RSV4 X-GP(售價高達9萬歐元，約港幣$83萬)上首次實現量產化。不同於車頭定風翼主要產生的下壓力(Downforce)以抑制起步孤輪(Wheelie)，腿部定風翼垂直安裝於車尾座墊下方，具備兩大核心功能。</p>
<p><img decoding="async" loading="lazy" src="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-001.jpg" alt="" width="827" height="551" class="aligncenter size-full wp-image-90171" srcset="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-001.jpg 827w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-001-300x200.jpg 300w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-001-768x512.jpg 768w" sizes="(max-width: 827px) 100vw, 827px" /></p>
<p>(1)直線減阻(Drag Reduction)，從上方俯瞰，這些翼片與騎仕的腳踝與小腿對齊，形成流線型的「淚滴狀」輪廓。這能引導從公平板(Fairing)流過的空氣平順地滑過騎仕腿部，減少車尾的亂流，從而提升極速與高轉時的加速性能。(2)彎道主動下壓力(Active Cornering Downforce)，這是該專利最聰明之處。</p>
<p><img decoding="async" loading="lazy" src="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-003.jpg" alt="" width="827" height="551" class="aligncenter size-full wp-image-90167" srcset="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-003.jpg 827w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-003-300x200.jpg 300w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-003-768x512.jpg 768w" sizes="(max-width: 827px) 100vw, 827px" /></p>
<p>當騎仕在過彎「出腳」或側掛時，腿部與車身之間會打開一個氣流通道。空氣會擊中內側(近地側)翼片的內表面，利用高低壓差產生向下的推力，將後輪更用力地壓向地面以提升抓地力。而外側翼片則會被騎仕的腿遮擋而不起作用，成功解決了傳統對稱式翼片在傾斜時力量互相抵消的問題。</p>
<p>RSV4 X-GP是現階段的最強體現，Aprilia藉此技術展示了目前民用電單車的極限性能。RSV4 X-GP 的數據極為驚人，可輸出最大馬力241ps/13,750rpm，最大扭力18.11kg-m，車輛整備重量僅165kg。空力效能方面，Aprilia聲稱其空力套件(包含前翼、底翼、側翼、腿翼及尾翼)產生的直線下壓力是標準RSV4的五倍，彎道下壓力則是三倍。</p>
<p><img decoding="async" loading="lazy" src="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-005.jpg" alt="" width="768" height="627" class="aligncenter size-full wp-image-90169" srcset="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-005.jpg 768w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-005-300x245.jpg 300w" sizes="(max-width: 768px) 100vw, 768px" /></p>
<p>據廠方公佈的最新的專利圖顯示，考慮將這項技術以更簡便的方式應用於街道跑車。不同於X-GP將翼片整合在碳纖維車身中，專利中的設計是安裝在乘客腳踏支架(Pillion Footpeg Brackets)上，車主只需拆下乘客腳踏，即可鎖上這組翼片，這種結構意味著該技術未來不僅限於旗艦型號RSV4，亦可能下放至RS 660，甚至作為原廠改裝精品銷售。</p>
<p><img decoding="async" loading="lazy" src="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-004.jpg" alt="" width="827" height="551" class="aligncenter size-full wp-image-90168" srcset="https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-004.jpg 827w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-004-300x200.jpg 300w, https://plus.webike.hk/wp-content/uploads/2026/04/171_web_19_Aprilia-Leg-wing-004-768x512.jpg 768w" sizes="(max-width: 827px) 100vw, 827px" /></p>
<p>雖然目前這類垂直翼片在街道合法性上仍有待法規確認(例如行人碰撞安全限制)，但Aprilia此舉無疑預告了2026年後的超級跑車市場，空力競賽將進入「全車武裝」的新階段。</p>
