Roland Sands can put other custom bike builders to shame with his built-for-the-track bikes. Not only is he a great bike builder, but a great racer, with many AMA 250GP wins and more in Britain. My favorite is his CR500 super single that he built amidst the 450 moto project for the spec WERA class. I’ve been combing the internets for pictures with more detail, but it looks to be a the obvious CR500 motor in a 1997-99 Honda CR250R frame, with a CBR600 Ohlins front end, and custom Ohlins shock, probably a supermoto shock. Please let me know what other bits and pieces you can name!
