why did you use such small resolution? with g-texture we can put any resolution we want, and there even is one helmet texture bigger than your helmets. and why did you mean to chose one of all three(you are advising the same texture in every readme)?
I've already done it with 3 Valentino's Rossi helmets.
These are separated because are different textures mods. As polodave caps or others ppl's clothes.
