A mate's got a fairly good, late-1990s RMX for sale.
Currently has NSW rego. I've ridden it, and it seems to do everything right - starts easily, goes well, not rattly etc - although it has the typical "more than 6-month old Suzuki" sloppy feeling.
His name is Richard and his number is 0409 413 878. Asking $3200.
Bike is in Canberra area.
