has anyone experience with JE pistons about weight, durability, etc.
I saw a set offered, but don't know them.
Any input is welcome.

They are very good pistons. Lots of racers and others use them. I think they are all forged.

Jon and Gert,
thank you for your comments.
Gert, do you know by chance how heavy the original pistons are? something about 500 gram?

IIRC, JE 435g & OEM 460.
If buying a used set and want fresh rings,
do buy from US, veeery much cheaper!

A word of warning about used pistons, Ducati's have a tight tolerance on the piston to wall clearance. They classified pistons as A or B fit. I bought a used set only to find they had too much clearance. They also wear in the ring grooves. I looked into stock bore J&E pistons, but no gaurantee that the Nikasil plating would not have to be redone for fit. I ended up buying J&E ST-2 pistons, sending the cylinders and pistons to Millenium for a bore and Nikasel plating, and shimming the 11:1 pistons to yield 10:25 compression. I use a FBF chip and 89 octane gas, the motor runs strong and gives me a consistent 50 mpg. I highly recommend J&E and CA cycleworks
