And here is another one of a great friend of mine, known around the Michigan D14 Enduro series as Young Ted. Here he is at age 83, aboard his 1977 Penton GS6 250. He was the prior owner of my 76 Penton (which he bought used in 1977). Ted still competes in various D14 Enduros - did the Jackpine in 2011 in fact. He and I are planning on riding the Michigan Cross Country Cycle trail next year, on our Pentons. A couple years ago he and I rode the entire trail (652 miles in 5 days), him on his Penton the entire time. I had planned on doing the same on my Penton, but a boned head move on my part resulted in me having to use my modern bike the first 3 days of the ride.
And this one is of another friend on his 1978 Yamaha IT175 doing what it was built for:
