<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>何谓“腿部定风翼”？这项装置最初出现在Aprilia RS-GP赛车上，随后在2025年底推出的限量版RSV4 X-GP(售价高达9万欧元，约港币$83万)上首次实现量产化。不同于车头定风翼主要产生的下压力(Downforce)以抑制起步孤轮(Wheelie)，腿部定风翼垂直安装于车尾座垫下方，具备两大核心功能。</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)直线减阻(Drag Reduction)，从上方俯瞰，这些翼片与骑仕的脚踝与小腿对齐，形成流线型的“泪滴状”轮廓。这能引导从公平板(Fairing)流过的空气平顺地滑过骑仕腿部，减少车尾的乱流，从而提升极速与高转时的加速性能。(2)弯道主动下压力(Active Cornering Downforce)，这是该专利最聪明之处。</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>当骑仕在过弯“出脚”或侧挂时，腿部与车身之间会打开一个气流通道。空气会击中内侧(近地侧)翼片的内表面，利用高低压差产生向下的推力，将后轮更用力地压向地面以提升抓地力。而外侧翼片则会被骑仕的腿遮挡而不起作用，成功解决了传统对称式翼片在倾斜时力量互相抵消的问题。</p>
<p>RSV4 X-GP是现阶段的最强体现，Aprilia借此技术展示了目前民用电自行车的极限性能。RSV4 X-GP 的数据极为惊人，可输出最大马力241ps/13,750rpm，最大扭力18.11kg-m，车辆整备重量仅165kg。空力效能方面，Aprilia声称其空力套件(包含前翼、底翼、侧翼、腿翼及尾翼)产生的直线下压力是标准RSV4的五倍，弯道下压力则是三倍。</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>据厂方公布的最新的专利图显示，考虑将这项技术以更简便的方式应用于街道跑车。不同于X-GP将翼片整合在碳纤维车身中，专利中的设计是安装在乘客脚踏支架(Pillion Footpeg Brackets)上，车主只需拆下乘客脚踏，即可锁上这组翼片，这种结构意味着该技术未来不仅限于旗舰型号RSV4，亦可能下放至RS 660，甚至作为原厂改装精品销售。</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>虽然目前这类垂直翼片在街道合法性上仍有待法规确认(例如行人碰撞安全限制)，但Aprilia此举无疑预告了2026年后的超级跑车市场，空力竞赛将进入“全车武装”的新阶段。</p>
