I think the Bill Patterson type of events probably made mx so strong. Many could afford the $300 SLs, XRs, Daxs , mini trials and even the omegas and could go racing. Went through the KX65/85s phase with my boys, you certainly need to be cashed up. Grat memories of those days. Great uphills and downhills at Wallan. Would be great in the cheap chinese bikes could help replicate something like it, always nice to dream.
