That is a shot of the KTM 540 watercooled. I used this configuration 1986+1987.
The pic is from the beautifull Reims racetrack in France.They were an excellent engine , never hade a problem, just changed the Mahle piston every 25 hours ( 6 -7race meetings) and that was it .I hade a new spare engine and never used it.
