The red bike is a 1967 250 Mk3. The headlight assembly was either a clinker in the parts bin at ducati, (not an uncommon occurrence) or it has been replaced. When I got the bike it had the buckhorn handlebars. I know how hard to find the clip-ons are so i put on a set of clubman bars. I recently was able to complete a set of factory rear-set foot pegs thanks to Malcome Tunstall at Syd's Cycles. Those are going onto the bike very soon.
The white bike is a 350 sebring with a desmo head and formula cam and was built so I could take a riders school at Hallet, Ok. It's a rather tight technical course and a lot of fun on a motorcycle. I have also had it out at an old naval air base that gets used on occasion for sports car club races. Right now it has no magneto or alternator so it is a total loss ignition. I am planning to put the electrics back in it and wire it for the street.
Back in the "80s I spent a couple of years working in a small Guzzi dealership where I developed an addiction to collecting bevel head singles. Fortunately there was an old cycle salvage in town back then and I pulled out a lot of Ducati stuff and dirt cheap prices. Oh for another chance to rummage around those old parts piles.
Ah well, those were the days! Moto Chuck
