For sale is the Rev 4 Stroke I have been riding. It is a 2007, the first and rare production model 4 stroke by Beta. The bike was originally ridden by Ray Peters in EX and then went to NY for a while. All owners have taken good care of this bike. The bike purchase includes the original 250 kit. The bike has bar ends and a throttle cam as additional features. $5000 obo. I have pictures if you want to see them.
