I would say the 1st one is a 250 made in December of 75, making it a 76, the 2nd one a 250 made is March of 74, and the last one, a 250 made in October of 74, making it a 75.

Rocket, thanks for info but I'm still in the dark as to frames in general. I'm not sure if any of the numbers mean anything are not. The three frame numbers have all got 175 KTM motors in them, frame # 54 51288074 (Dec 75)is a older frame then frame # 54 40371971 (March 74). Frame # 54 41078661 looks to be a (Oct 74) as you stated but has the 175 motor. Heres a new number, frame number (7 21159825) it also has a 175 motor. D&D

How to ID your Penton can still be found on the old POG site.

All the 74 frames that fit ktm moters started with 54. All were the same 175-400. 74 and a half frames had the multiple shock mounts.
