Mike I believe pre-modern class bikes are front disc brakes with rear drum brakes 1984-86 CR's, 1985-87 RM125's, 1985-86. RM250's, 1985-87 YZ's, 1982-1985 KX's, ect . .
The problem with getting on a 81 Maico 490 is you'll be throwing rocks at your old bike once you switch back ! I've ridden/had them all and the 81 490 is one of the best/if not the best PV I've ridden. Close 2nd is my old 83 CR250.

"supercross is over with, why do I got to go 3, 3, 3 and see god every time through the rhythm"
Great weekend of racing, Like to thank Dave and Dirt Country for all the hard work. Much appreciated. I had the most fun ripp'n on my newly built 1986 Rm125 that bike is a blast to ride !
