Here's a couple of Indian timelines. The first covers the "true" or Springfield Indians, from 1901-1953. The second timeline covers some of the revival attempts.
Here's the timeline for Yamaha and Star cruiseres. It also features Yamaha's V4 models, the VMax, Venture, and Royal Star. As well as the odd ball V-twin standard XV550 Vision.
This chart shows Harley's model families as well as their infamous engine lineage. For now all my timelines only go back to 1965 for simplicity's sake.
