Go for a 2006 - 2008 270 Beta Rev 3.
Great motors, price is reasonable, good parts support. Bike is till very rideable.
Older bikes are going for around R15-20K, but are starting to get a bit long in the tooth when you can pick up a good condition 2008 for around R25K. Graham Harris brings in Betas, & has a comprehensive stock of spares, and ships nationwide.
The Shercos I don't know that well, none of the GP guys ride them - the importer used to be in durban, & I think it is now with one of the Durban BMW agents now. Not many of them around though.
Gas Gas is good aswell, imported & supported through Rockgarden in CPT, not as many older bikes around though, as they only took over the agency a while ago.
Montessa 315s are good, but also getting long in the tooth as they haven't been available since 2001/2 when honda pulled the 2stroke motor. Their 4 strokes are good for the top riders, but very pricy & scarce.
Any more questions?
