What is it you are after? From the pics it looks like its just the mv logo and the senna lettering with the emblem.
Ideallly needs someone with a vinyl plotter to machine cut the mask but it may be possible to hand cut frisket film.
I have an old helmet that I will use as a practice because i'm stll gaining experience and would make sure its possible before doing the real thing.
If it is just the lettering and logo then I doubt it would cost much at all.
