{"product_id":"st-2m-camshaft","title":"ST-2M Camshaft","description":"The Yoshimura ST-2M camshaft is engineered to unlock the performance potential of Honda's 125cc horizontal engines, providing a direct bolt-on upgrade. This camshaft features a higher lift than the ST-1 series and utilizes an original polynomial profile, eliminating the need for specialized valve springs.\n\nWith a maximum lift of 6.5mm on both intake and exhaust and a 1mm duration of 250 degrees on both sides, the ST-2M camshaft offers significantly improved power and torque. The standard tappet clearance for both intake and exhaust is 0.08-0.12mm, and precise measurement and adjustment are crucial during installation. Fuel adjustment is also required to achieve optimal performance and prevent issues.\n\nThis camshaft is compatible with the GROM (2013-2017 models), Monkey125 (2018), and Super Cub C125 (2018). Please note that this product is intended for closed-course use only and is not compatible with 2021 and later models. Installation requires careful measurement and adjustment of tappet clearance and valve timing, with detailed instructions available on the Yoshimura Japan website.","brand":"Yoshimura","offers":[{"title":"Default Title","offer_id":52664160944440,"sku":"211-40A-2151","price":161.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687544072.jpg?v=1784334302","url":"https:\/\/store.motormia.co\/products\/st-2m-camshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
