It's always mystified me that during the initial VMX years when pre 75 was the only game in town, the 4 stroke class was really well populated by a full grids of bikes ranging from tricked up XL Hondas, B50 Beeza's and even the odd Ducati. Today, in Evo, Pre 85 and/or pre 90, with some really decent (and comparitively cheap) 4 stroke tackle to choose from, racers don't seem to be all that interested in racing them. Literally tens of thousands of XL's, XR's, TT, XT's, DR's and KLX's were sold during the eighties so why isn't that eighties popularity reflected in today's VMX entries?
