i got tired of not being able to safely leave my helmet with my bike .like you can with almost any other bike. sooooo i made a simple, effective and nice helmet lock. i just took a piece of 1/8" flat metal about 4 inches long and 3/4" wide, and bent it twice by locking it in a vise and hitting with a hammer.( to form a hook) then i rounded the corners with a grinder, drilled a hole in it and on the flat piece under the seat, and screwed it down with a large metal screw and a lock washer. my triumph is a sprint rs, im sure it can be done on other models if the location is modified. anyways works really well. ill try to put the pics on now if i can figure it out.
heres a link to the pics anyways....
