Be sure to check out the all new Production Year Guide:
http://www.pentonusa.org/prodyears/prodyears1.asp
This covers every Penton motorcycle ever produced - from the 1968 Steel Tanker to the 1977 Kenny Roberts Flat Tracker, and some very low production models inbetween.
Many thanks to all those who contributed their time and efforts in compiling the information for the Production Year Guide.

Bill and Karen,
Thanks for the great section that addresses the many changes in the different years for Pentons. Is this going to be a living document in that you would like for us to send in any amends that we see should be updated?
Great JOB.

Great work...this makes it much clearer especially to the neophite Penton restorer (like myslef). Now that I look at your chart, I see where I have made several critical parts mismatches between my late '73 and early '75 Jackpiners. Did Penton ever have a conical front hub on any of their models prior to '77?:D

The new Production Year guide is an excellent piece of work. Thank you very much, folks, for providing us such a comprehensive data source. Fascinating info on the limited-production units, also.
