If you need an extra master link, pick your size and type chain.
These are the standard style 'clip' links, and are not generally recommended for larger C.C. bikes, modified bikes or anything that was not originally equipped with clip type link.
EK recommends using a riveted-type master link for all street and dual-sport motorcycles, and EK’s clip-type as an alternative for off-road use. Try using EK’s patented screw-type master link, provides rivet-like fit and strength without special tools or removal of the rear wheel.
