DT1 Road Race Frame? #1
I noticed there were some DT1 road race discussion here. WHat frame would work for a DT1 that is legal in 68 and under classic GP? X6 maybe?

DT1 Road Race Frame? #2
Yamaha R5, you will need to make your own motor mounts but it is a good handling frame. Even though it is a 1970 frame AHRMA allows it in 68 because of the '68 R2 frame, which was similar.

1970 DT1-C Grand Prix race bike
1970 DT1-C Street tracker
1968 Honda CL90
1973 Honda CR250
1974 Honda MR-50
1966 Triumph Tiger Cub
1970 Suzuki TC90
1947 Mustang
1974 Suzuki TC185

Good recommendation Pillsbury. From what I've read the R5 frame had the exact Yamaha factory road race frame geometry just with added light brackets and maybe a little heavier tubing for street use.

1963 YG1-T, 1965 MG1-T, Allstate 250, 1970 CT1b, 1971 R5, 1973 AT3MX, 1974 TS400L, 1975 RD350, 1976 DT175C, 1976 Husqvarna 250CR, 1981 DT175G, 1988 DT50, 1990 "Super" DT50, 1991 RT180, 2017 XT250

By "X6" do you mean a Suzuki T20/T25 Hustler? I think I might have one of those frames in my garage. Inherited it from my uncle who saved it from a metal recycler. I have the tank, wheels, headlight/speedo.
