    1965 250cc Ducati

    We have shown a lot of Ducati Super Sports here on CSBFS, and they are called super for a reason. But we have to remember before there were twin cylinders offered from Bologna Italy, there were the equally spectacular singles. With names like Diana, Monza, and Mach 1 and Mach 3 (or MK1/MKIII) Ducati offered riders a very quick and well handling single before the Super Sports took over the world. This 250cc Ducati offered now on eBay is one of those super singles.

    From the seller

    Up for auction is this beautiful 1964 Ducati 250. This fabulous bike has been assembled with no expense spared and a great deal of attention to detail, yet another project forces me to sell her. The bike has been highly modified from stock but with an aesthetic appropriate to the period. She starts, runs and works superbly. It has been fewer than 1,600 miles since completion of her frame-off resurrection. Some highlights of this bike are as follows.

    The one thing that would be nice to know is what this bike started as. The seller lists it as a 250, and lists the vin number so hopefully a reader might be able to decipher it for us. The reason I ask is not so much to know what you get, but more to know where it started.

    The sellers list of upgrades

      • Custom aluminum seat and tank 
      • Alloy wheels with stainless steel spokes
      • New correct size Metzeler ME22 tires (I just put these on – these sensational handling small bike tires have to be purchased overseas)
      • 12 Volt 120 watt Electrex World generator conversion
      • Solid state regulator/rectifier with capacitor
      • Pazon electronic ignition
      • High compression piston
      • Oversize valves
      • Megacycle street/track cam
      • Dellorto VHB 29A carburetor
      • Stainless steel exhaust
      • All new bearings throughout the engine and chassis
      • Much, much, much more

      (Just a personal opinion, the Dell’orto VHB is said to be a great carburetor, with great flow characteristics, but I think a round case single needs the round and elegant SS1.)

    These pre-desmo singles are a little confusing, and might be the reason the seller doesn’t list the model name. First offering in 1961, the 250cc bike was called the Diana, or if in the UK the Daytona. It appears to have about 19hp and with the 5speed unit transmission could reach 110mph. We know that this 250cc did not start as a Monza, because this 21hp version was not offered until 1968. The Mach 1 was offered this year and had 28hp of non Desmo power. The Mach 3 was offered later then 1965, so another possibility eliminated.

    No matter what the bike started out as, the seller has spent a lot of time and money getting the bike that they wanted. As with any altered bike, you have to find the buyer who agrees with you, but I think there will be lots of buyers who will agree.BB
