ktm cylinder question
anybody know if the 550 2stroke in '95-'96 used a steel sleeve like cr500 or was it aluminum sleeve with nikasil plating ? it seems the pistons have went extinct, im trying to find out why. wiseco, pro x and vertex doesnt make one either

i found some stock cast pistons, only problem is their real expensive. i dont mind using a cast piston, but im going to search other avenues before forking out the cash. ive been told that wiseco is supposedly in the process of making a run of pistons for my bike, im trying to contact the other company to see if this information is true and when they might have a date theyll be available.
guess i could have left the website hey. http://www.ariaspistons.com

I have conversed a little with the sales manager for Wossner pistons USA. Nice guy. He says they will make any custom piston as long as you buy 4 like pistons. There manufacturing plant is in Germany where the pistons are made then shipped here to a warehouse in LA somewhere. He told me if I sent him a piston, they would make it. With your aluminum bore, as long as you keep it the stock bore size, 4 pistons would be a lifetime supply but you would have pistons.
Most of their pistons are single ring, and do make them for CR 500's. I have seen one of these pistons (for a 250r) but they are very lightweight like the old Wiesco's used to be and have a antiscuff material applied to the piston skirts. Real nice looking piece.

I see on their website all makes and models of KTM pistons both 2 and 4 stroke but the old 440-550 cc machines aren't listed. It would be worth a try for sure.

its something ill keep in mind. i did find some pistons at a ktm shop in claifornia. i think they are mahle pistons. i have no experience with mahle, but everyone i talked to said they are top qaulity. also, i heard wiseco supposedly has some 550 pistons in the works, i havent been able to confirm it but thats what i heard. the problem with wiseco is they have a 12 order minimum on 2stroke pistons. one way or another ill get a pistonLOVEMYCR500 wrote:I have conversed a little with the sales manager for Wossner pistons USA.
