Made a pipe some years ago for a guy that beach raced in Nth Qld. They seemed to be right into it.
The nearest I got to beach racing was some dune outcrops out the back of Mildura. There was a row of 44’s on one lot, probably used for slalom by the locals.
It was a lot of fun on my DR600, you could really lay it down for a turn just like a 125 on a MX track. The wheels would bit into the sand like it was on rails.
Wasn’t good to stop in it though, it would dig down to its axle while trying to get moving again, slowly it would climb back on top with speed, not unlike a hydrofoil ferry
