That's a clean and well thought out RT1 Jay. I like the 'chevron' style swingarm extention..very well done.
What's the score with the motor, is it a stocker or is it RT1MX/GYT? I don't think the early tank will weigh much, if anything, more than the current RT2MX item, and the bike'll look so much more period.
What's happening to the DT1?
