The product description highlights a 7.69% peak horsepower gain when compared to OEM velocity stacks on a Ninja 500. Features include a simple, bolt-on installation process with no required modifications, allowing for easy return to stock configuration if needed. The stacks are manufactured from a chemical-resistant compound, capable of withstanding gasoline and other harsh chemicals commonly found in the engine environment.\n\nThe easy, tool-free installation makes achieving real-world power gains accessible. Demonstrated power gains were achieved using a Ninja 400 outfitted with WORX V2 Velocity Stacks and comparing them to the same bike outfitted with OEM velocity stacks.","brand":"TST WORX","offers":[{"title":"Default Title","offer_id":52664037703992,"sku":"N400VS-2","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687723778.jpg?v=1784332315","url":"https:\/\/store.motormia.co\/products\/v2-velocity-stacks","provider":"MOTORMIA","version":"1.0","type":"link"}
