Model # of Wiseco Piston Kit for'90 KTM 250 EXC


Jun 4, 2007
I saw a Piston Kit on **** that stated "You are bidding on a wiseco piston kit for KTM250 dirtbike models 1990 to 2002". It is a Wiseco Piston Kit. I checked on Wiseco website & called them and they said they never made a piston for my year/model bike.

Can anyone shed some light on this?? If you have a Model # or P/N this would help me greatly. My cylinder is standard bore 67.5 and the piston has 2 rings.

BTW my engine overheated after my clutch cover perforated, allowing tranny oil and coolant to mix. My piston sustained damage and the bottom ring seized in the channel. I am trying to get it back on the trails.
