Very nice rig, I remember those also earlier RD400's Blue tank black motor shiny fins! I rode a 380 Ram Air Suzi on a novice road bike course once I remember it had a gear counter on it pretty modern for the day. We used to call them Yamaha-ha's mind you my mates RZ500 could keep up very well with my VF1000R it was only at 220Kph+ the R showed its long legs we swapped bikes for a ride but I was used to the pulling power of the 4 stroke and not the twitchy nature of keeping a bike in the power band through the gears it was ok.
