Garth has a mighty KLX250s that is nearly stock.
My bike is a KLR250 which is also nearly stock.
Both bikes have been majorly upgraded with the WalMart seat pad.
In addition to that Garth stuffed some extra foam underneath the pad and I sprung for the Dick's Sporting Goods stadium seat pad upgrade. The KLR650 riders seem to be characterized as cheap on this board. I'm just trying to live up to that (at the 250 level).
