I never knew about the 72 RA, I was with Firko and the 75/76 thing, I even went to one of the race meets at Amaroo where Gaston was having a ride, still remember how much Suzuki had done to the RA to fit Gaston who was a really small guy. Foot pegs for one.
I guess what I was trying to do with my TM125 10 years ago was to make a 125 that looked like a works bike, look forward to what you come up with, check out VMX issue 3 for a look at my one.

On the race day at Amaroo, I crashed my brains out on the jump on the main straight, it was made bigger for the event and my MX250B crashed all the way to the left hander at the end of the straight, day over, race one! way way out of my depth.
