Pretty much anything not covered by the topics above. Short lived production bikes or vehicles, Electrical, Tires, Paint, Brakes, etc. Use this for tech questions, and "Shoot the Bull" for general conversation, no tech.
The Legend has order forms, list prices, and production numbers for models up to 1969. The production numbers must be taken with a grain of salt, as they are really fiscal year numbers, not model year numbers. I enjoy my copy, but I enjoy books... VPH-D
