I want to Change piston

Now I used parmrkit cylinder piston d 57 i want to change piston to d58 - d60 what brand piston 

i can use? please let me know  ... Thank so much



its possible but costly to change the piston.

its a aluminium cylinder with a steel tube  in it. This tube has a nikasil plating.

you have to change the tube and replate with nikasil-----   more than 350 Euro

Better to buy a new Kit cpl.


look for this - a more powerfull piece than parma :
