I went with about 75% coverage with Clear-Bra which is a 3M product. You can even get it in different thickness.. Prof installed, they have computers they share cut-outs info on line.. Mine I did full tank, leading edges of fairings and front fender & headlights, complete tail peice as it seemed every once in awhile I would nick it with either boot or knee puck.. Found this is a must to keep your paint in shape as So.Cal canyons have lots of fine little rocks that either you kick up or guy in front of you throws back at you..
Course, then you wad your bike up and it's a moot point any way's. Does make it easier to pick up your peices tho... The clear tape holds alot of the little bits together..
