+1. But at only 600km? Holy cr*p!!! Is it an ex-demo bike by any chance?

Excluding errors in assembly, the primary drive crank nut can only become loose through wear in the main bearing/plate washer/primary gears. It can only come undone if no lock washer was fitted.

For your info, I had a similar problem at 60,000 miles (18 months-ish) that was rectified under warranty (new main bearing, crankshaft, piston etc).

Do keep us posted as to the outcome........
