{"product_id":"hayabusa-2mm-stroker-crank-kit","title":"Hayabusa 2mm Stroker Crank Kit","description":"The APE HCK-08LB is a 2mm stroker crank kit designed for the Hayabusa. This kit utilizes a brand new 08 Hayabusa crankshaft that has been meticulously lightened and balanced to tolerances of less than 1\/3 gram. The rod journals are fluted to ensure extra oil delivery to the rod bearings, contributing to longevity and performance.\n\nKey features of this kit include the inclusion of a counterbalancer gear removal and a spacer plate. When this kit is installed in a 1397 motor, it results in an increased displacement of 1441cc.\n\nThe crankshaft undergoes a comprehensive machining process by APE to remove weight and narrow the counter-weights, a technique sometimes referred to as \"knife-edging.\" This lightened and balanced design is crucial for racing applications, as it reduces the gyroscopic effect of the rotating mass. A lighter crank not only contributes to increased horsepower by reducing parasitic loss but also significantly improves the motorcycle's handling characteristics, allowing for quicker throttle response, faster engine acceleration, and a harder pull out of corners.\n\nAPE is globally recognized for its expertise in race preparation of four-cylinder plain-bearing crankshafts. Their extensive experience, spanning over 28 years, is applied to every modified motorcycle crank. The advantage of a lightened crank is multifaceted, offering quicker throttle response, less wasted power, more power to the rear wheel, faster engine acceleration, and improved cornering due to reduced gyro effect. The fastest no-bar bikes in the world reportedly use APE Billet crankshafts.","brand":"APE","offers":[{"title":"Default Title","offer_id":52686932967736,"sku":"HCK-08LB","price":975.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660675367.webp?v=1784878615","url":"https:\/\/store.motormia.co\/products\/hayabusa-2mm-stroker-crank-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
