piston on left is a 7900 used piston, with ring it weighs 85.4 grams , skirt width of 32mm/ 1.260 inch
middle is the wide skirt wiseco piston, with ring it weighs 79.7 grams and has a skirt width of 1.670 /42,5mm
right piston is a stock 272 piston weight was 82.9 grams with ring , skirt width is 35.83mm/1.414 inch,
so race piston is wider and lighter and will fit the 7900/272/460 stihl , I built this piston maining for a race piston and to be run on alcohol/nitro, as you can see its coated everywhere , I also have pistons made in 60mm, 62mm, and 66mm
