Here is their website, so you can look up fitment for your specific bike, and then chose diameter. I believe they offer A through D sizing. Once you have the part number you can search for a vendor anywhere you want.
Thank you a lot

This wossner isn't 72.01mm ,72.01 is cylinder bore ,but the piston is size B or 71,94 or 71,95mm .Put wiseco they are 72mm and are forged too .Vertex have 71,96 and 71,97mm .

quote from wiseco site:
Quote:
Wiseco Powersports pistons are designed for optimal piston to wall clearance for the specific bore size of your engine. For example, your 125cc dirt bike engine is 54mm bore, the Wiseco piston is designed just for that bore size, and does not require any specific adjustments to fit properly.
So their piston for gasgas has same diameter like original pistons for gg. For Boresize of 72.00mm http://www.wiseco.com/ProductDetail....011&AppID=4988

Such a strange situation. gg have only 3 piston sizes, and they don't cover anything eventually.
hmm and seems like ktm have the similar situation. Sorry guys, it's first 300cc for me, and everything is new. I just trying to understand how to live with it)

oooooops sorry for the incorrect info.
Maybe check ProX pistons.... I know with my last bike (honda cr250) honda only offered an A or B piston, but ProX had A, B, C, and D for me to chose from.
