The first outlet is large and has as free a flow as possible so as not to throttle the engine. The second outlet is higher, narrower, and angled upward.<\/p>\n<p>The smaller pipe cross-sectional area increases the exhaust jet and generates additional pressure to the rear and upward. This directed thrust is intended to press the front wheel more firmly onto the asphalt, which should reduce wheelies and improve acceleration when exiting corners.<\/p>\n<p>As soon as the speed increases and wheelies are no longer a limiting factor, the flap opens again in favor of the large tailpipe with maximum flow.<\/p>\n<p><!-- notionvc: 681e3ee3-9e17-4d10-85bf-98a01436ed1d --><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1030\" height=\"773\" src=\"https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1-1030x773.jpg\" alt=\"\" class=\"wp-image-166427\" title=\"\" srcset=\"https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1-1030x773.jpg 1030w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1-300x225.jpg 300w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1-768x576.jpg 768w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1-1536x1152.jpg 1536w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1-150x113.jpg 150w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1-450x338.jpg 450w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1-1200x900.jpg 1200w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_3__1.jpg 1726w\" sizes=\"(max-width: 1030px) 100vw, 1030px\" \/><figcaption><\/figcaption><\/figure>\n\n\n\n<h2>Exhaust gas for cornering stability<\/h2>\n<h3>Downward-facing outlets for additional cornering thrust<\/h3>\n<p>A second patent shows a system that directs exhaust gases through a narrow, downward-facing pipe when the bike is leaning. At maximum lean angle, this outlet faces sideways toward the outside of the curve. The escaping exhaust gas jet acts as an additional lateral impulse, which is intended to push the motorcycle further toward the inside of the curve.<\/p>\n<p>It is interesting to consider that motorcycles cannot deliver full engine power at extreme lean angles anyway. Redirecting some of the energy into a supportive thrust effect could therefore be considered a sensible compromise.<\/p>\n<h3>Variable outlets on the left and right<\/h3>\n<p>A further developed variant describes two pipes directed downwards and diagonally outwards. This should make the effect usable regardless of how steeply the motorcycle is tilted. The system could also be effective for slower curves or lower lean angles.<\/p>\n<p><!-- notionvc: 5363fc29-0692-4f64-a388-dd612308c694 --><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1030\" height=\"772\" src=\"https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1-1030x772.jpg\" alt=\"\" class=\"wp-image-166428\" title=\"\" srcset=\"https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1-1030x772.jpg 1030w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1-300x225.jpg 300w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1-768x576.jpg 768w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1-1536x1152.jpg 1536w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1-150x112.jpg 150w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1-450x337.jpg 450w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1-1200x900.jpg 1200w, https:\/\/www.motorcycles.news\/wp-content\/uploads\/2025\/12\/2025-Auswirkung-von-Auspuff-auf-Handling-_2__1.jpg 1807w\" sizes=\"(max-width: 1030px) 100vw, 1030px\" \/><figcaption><\/figcaption><\/figure>\n\n\n\n<h2>Combination system with multiple valves<\/h2>\n<p>Although Yamaha has filed two separate patents, the drawings suggest that the ultimate goal is a combined design. This would feature both a large, rearward-facing pipe for maximum power and smaller pipes for anti-wheelie and cornering stability.<\/p>\n<p>Multiple flaps inside could open the appropriate exhaust path depending on the riding situation. Since the valves are located inside the exhaust and no external aerodynamic elements move, such a system should not violate existing or future regulations on active aerodynamics. Many racing motorcycles already use internally controlled exhaust flaps for engine braking control, for example, which further supports the technical basis.<\/p>\n<h2>Outlook<\/h2>\n<p>Even if the potential advantages are only minor, they could be decisive in racing.
