US Cutter MH 365. It is a 12 inch model. My thought is the 12" should be wide enough for most any graphic needed on a bike- whether it is a tank, side bag or faring. Of course it can cut as long as needed. If I ever do need something wider, I can tile the stencil. If you saw from one of my other posts, I really had a good experience with US Cutter. All except the manual that came with it. With a couple tries it was basically an easy setup.
If you do buy a US Cutter model, ask for Levi he is one of the best over there. Some of the others tried to upsell and say that the model I wanted wouldn't provide what I need. (This proved to not be correct). The model they wanted to sell was almost double what I paid.
