KOSO Cam Chain Tensioner for Honda Grom/Monkey ('14-'20)

KOSO Cam Chain Tensioner for the Honda Grom/Monkey 125 is a high-quality upgrade to OEM. Made from the resistant high-quality material, Koso chain tensioners could save your engine from expensive damage. Developed to have a larger footprint arm that is made out of billet aluminum, causing less wear and tear. The steel sprockets it comes with will last longer and is highly recommended to install this product on high-revving engines, especially big bores. Koso came up with this long-lasting solution to replace the OEM chain tensioner which has a tendency to wear prematurely. This comes with the button included. 

Note: Works on the stock engine and is highly recommended to use with our Big Bore & 4V Head kit. Fits 2014-2020 engines. Recommend installing flat washer behind arm to prevent binding.
