I had a 69 mk3 350 demo that I bought from dealer in Roanoke, Va. Raced it also in AAMRR in 68, 69 and 70. Broke the crank at Bridgehampton race tract and got a new crank. The end of the crank which had the gear for the operation of the shaft that drove the valves seized up because the plane brass bearing in the side cover failed. In any can sold bike to a guy in Florida who still has the frame but to the Desmo motor out. I currently have a restored 1965 Mach 1 that I showed locally a couple years back and at the Quail event here in central California. Won the best of show in Hanford then got invited to go to the AMA national show in Las Vegas. Took third in the European class. Learned a lot about showing bikes and judges that know what they are looking at vs the ones who do not. In any case I have tons of parts to put together a Mach 3 250 soon. They are great motorcycles. Too bad that Ducati still does not remember the singles kept them going before they went to the twins and now 4 cylinders for their street bikes. I have a banner that says Ducati worlds lightweight leader. I used to put it up on our van when we went to VIR or Summit Point raceway back in the late 60's. Used to always go with my brother who had a real Dunstall Norton ATLAS that was built by Dunstall before her did the change to the Commando. Oh well, those were the days when going to Daytona was the big deal and a huge race to see the factory support for BSA and Triumph. Thanks for the great article. Have my Mach1 in my garage covered up. It is my most important bike that goes back a long time. Thank you Ducati for making such great memories and wonderful bikes back then.

I remember Leon Cromer. I was the WI Berliner Ducati rep and Mike Berliner asked me to go to Laconia to support Leon. My first novice race was Daytona 1968 on a 250 Ducati Scrambler. It Dropped an exhaust valve and Reno Leoni provided a top end. I qualified 5th out of 225 at 126mph 10500rpm. Weighing 200 and a standard ratio gearbox held me back on acceleration, but I finished 12th. Imagine 2 Ducatis in the top 5 Qualifiers against all those Yamaha TD1Bs
