Ciao Guest, The owner of this website and GTMotoCycles.com lost his home completely on the morning of January 8th in the L.A. Wildfire Storm. Most of his neighborhood is gone, and a few friends were killed along with their pets. The GTM SHOP and STORE are functioning normally, but we DEMAND EXTREME PATIENCE on orders as we are a SMALL business and Todd usually has his hands on nearly every order before it goes out. You can find more info on a post named L.A. Wildfires in the USA section. Our heart and best go out to everyone in this horrific disaster.
There are numerous books that have been published showing photos of the motorcycles from that era.
This will be your best source of information as the factory has had a long-standing history of never publishing their paint and finishes to the public.
You are going to have to put in effort to determine your answers.
