In the 1975 Yamaha "Circuit" magazine (a magazine for European dealers) (Oh, what a lovely magazine that was, so many beautiful...... sorry, we have to talk bikes!), was this feature about Don Vesco, who had just broken the land speed record with this twin TZ750 powered streamliner to 302.928 mph or 485 km/h!
