the Kawasaki ZX12 has the battery "securily encased" within the monocoque frame, similar to the 14,, battery securement has always been a "small" point of contenution whenever ive had my 12 tech'ed,, i have since replaced the rubber strap that goes over rhe battery with a metal one, over retention? yes, but its done, there are no more explinations in tech, everyones happy,
