Hello,

After a big search with the help of Paul (Active member of NSR-WORLD I don't remember his nick name) I think I (we) managed to find the solution for the NSR crank big end bearings...

The manufacture of these bearings is a Japanese bearings manufacture called "IKO"...

The code of the big end bearing is KT253216... IKO has label this bearing as 25mm x 32mm x 16mm but actually the true dimensions is 25mm x 32mm x 15.8mm

I am waiting Paul's input to verify this or anyone else knows something else about the big end bearings...

Regards
Michael
