Tankslapper makes them pre-cut for Triumphs. The kit I bought had two side pieces and a center piece. It came with a little 3M squeegee and a blister pack of the correct type of liquid soap.

They apply with soapy water and a squeegee. Just when it seems they aren't going to lay down flat from 10 or 15 minutes of squeegee work, they do [lay down flat] even on a curved surface.

If you want to remove the film, I'm told it peels right off without paint damage. No adhesive is used, but they don't fall off or shift unless you want them to, regardless of wind or weather.

They're pretty close to invisible when in place.

Their product line has changed quite a bit since I shopped there. It isn't readily apparent what fits which bike anymore. A call or email to them might prove useful prior to ordering.
