I own 2 sidecars ,one is painted pink and my wife and youngest son ride it for pleasure.The other one my two boys raced it and it was a worked cag that beat water cooled sidecars...yes there are quite a few W/C sidecars here in SA.
Some of the W/c sidecars are A/c rollers that have been converted and we have two in SA that were SQ Blatas with a Detachable sidecar fitted to them.
