I have used trim material available to me locally. It is thinner, and less metal, more plastic than the original. I buy it by the foot at the local Mercado Publico (swap meet) and is available at AutoZone, O'Rielly, CarQuest, etc. It's fine for 'driver quality' bikes, and is seamless- no need for the extra trim clamp pieces. I have a good independent auto parts supplier here, so next time I'm going to go through their catalogs with them and see if there's something available that's closer to what our bikes use.
