1973 750 Desmo
1973 Spaggiari Desmo Racer for Track/Street,
This machine carries a clear, valid US
title for Arizona.
offering "For Sale" this twin of my 1973 Ducai 750 Desmo
Spaggiari vintage racer for street or track as it has many items
that came from my Spaggiari AHRMA and CCS race bike in addition
to new trick race items. Frame number is DM750S*755317.
my dream to build a twin copy of my Vintage Racer for use on the
street. It was only a dream until I was given the opportunity to
buy a large bevel drive inventory from The Netherlands.
beautiful motorcycle is my last Round Case bevel drive Ducati
that I will sell. The condition of this bike should NOT be
considered "Unknown" as most everything is NOS or brand new.
Malcolme Tunstall from Syd's Cycles built this engine to match
the Desmo structure of my Vintage Racebike. The engine has been
fully rebuilt from the crank up and Malcolme built this "Blue
Printed" version of my Spaggiari Desmo vintage race bike.
Malcolme is a very talented racer and tuner in his own right and
he and Syd have shared their expertise and a number of race bits
with me over the years when I was most active in Vintage Racing.
It was a natural decision to make a spirited race engine out of
this Sport engine which is how my race bike engine also started
a great deal of money that went into this engine to complete a
full from the crank up "Blue Printed" engine to factory race
specifications. The crank was magna-fluxed and Falicon balanced
the new lightened Super Sport rods. Malcolme used Hasting piston
rings on Borgo Super Sport pistons. All bearings to include the
main engine bearings are brand new and not the cheap items that
can be found on the internet. Viton valve guides and a new
electronic ignition were installed. All transmission gears that
needed replacing were replaced with NOS items. Additionally, ALL
bevel gears in the bottom end of the engine are NOS and were
replaced as well as a new clutch and internals. There is also a
large billet oil pump from Ducati Kamna in Germany for maximum
engine cases were also pressure tested and any hairline cracks
or imperfections were professionally welded and fixed. The cases
and lines were bored professionally to take the Super Sport
Borgo pistons and we used 900 ss Desmo heads with new rockers.
This race spec engine picks up revs very quickly like my race
bike but it also starts on the first kick and with the lever.
The kick-start lever is off of my race bike and it has a
reinforced boss and is not, therefore, original. However, I have
the original Sport lever if you prefer. You can choose either
engine, number 755606 DM750 started its life as a 750 Sport and
came with a damaged narrow frame. When I conceptualized this
bike, I decided to combine the best of the Spaggiari racer and
the comfort of the 1972 Sport of which I have restored and owned
2. The deep orangey-yellow Sport was computer matched from those
bikes and I had copies of the striping that I made into decals.
As I was able to travel with my wife to Italy this year to
celebrate our 30th Anniversary, a trip to the Ducati
Museum was on the schedule. I was able to stand next to the
original Spaggiari Ducati Scuderia Corse race bike that I
modeled my bike after and I can say that it is a very faithful
copy of that bike.
As a result, in combining the
best of the Spaggiari race engine, I decided to use a GT frame
with the wider rear seatbase as I had additional 72 Sport style
bodywork. Additionally, I was able to create the same rear set
mounting points as on my 1972 Sports. Now that I am a "broader",
older guy, I find the wider rear subframe to be very comfortable
when riding at full speed and full lean.
2 sets of exhausts that come with the purchase of this beautiful
motorcycle. First there is a 2:1 system for the street with
baffling and a set of Imola high pipes when going to the track.
Both sets of pipes have been ceramic coated. The 2:1 exhaust
system came off of a Dutch race bike and in my opinion has real
character, however, the Imola high-pipes are recently
aluminum Imola race fuel tank has not seen fuel until last week.
It has the internal baffling to minimize the weight shifting of
fuel load upon hard braking and hard acceleration. I bought this
aluminum piece of race art in Germany and it is a top quality
item. There is a Monza cap (my preference) for street use and
there is also a flat aircraft style fuel cap that comes with
this machine for the track.
Super Sport wire wheel set with 3 disc brake set-up came from
Syd's Cycles. Malcolme knew that I was racing my bike and
recommended my using these strong Akront rims with stainless
steel spokes on the original hubs. I really like the strength of
this wheel set at the track as it is very confidence inspiring.
Floating rear brake caliper is thanks to my friends at Syd's. If
you will be racing this machine in Europe, I can supply
undrilled discs for the front wheel as well as the caliper
carrier for Lockheed style brake and magnesium caliper carrier
as I understand that a floating rear brake system and drilled
rotors is not allowed in European Vintage racing. Those items
will be included in the sale of this machine as well.
rubber is new and thanks to Steve at Bevel Heaven. Front is AM
22 and 110/80 and rear is AM 23 and 130/65.
I am also
using the rebuilt Cerriani front forks that came with this Sport
and rebuilt with the Works spring kit from Bevel Heaven which
makes a huge difference in performance. Totally restored
Marzocchi rear shocks hold up the rear of the bike. The dual
disc set up came off of my racer but the Grimeca master cylinder
is new as well as the new front Brembo F08 calipers. As this is
a race replica, I had chain guards made in Carbon Fiber as well
as the license plate bracket. They are new and the fabric of the
carbon weave is dynamic which is why I kept them in this state.
However, would consider painting if preferred. Front fairing is
900 Super Sport as is the instrument dash that houses Veglia
tachometer and speedometer that were original to the Sport.
painted the frame the same 72 Sport yellow like the Spaggiari
race bikes and the front fairing, both fenders, seat base and
side-covers are painted that same 72 Sport yellow with the black
72 Sport decals on the seat base and side covers. Originally, I
had the "Z" painted on the Imola tank but due to the size of the
tank , I decided to use the additional set of Spaggiari decals
on the Imola tank that I believe look much better and are more
proportional. I am pleased with how the color scheme of the bike
worked out and it is very satisfying to be getting the accolades
on Social Media or when this bike is in public. This Spring
2014, the beauty of this motorcycle was recognized and resulted
in winning Best In Class for Italian bikes at the Tucson Vintage
Motorcycle Riders Association Vintage & Classics Motorcycle Show
for Southern Arizona. However, this Ducati 750 Desmo with a
headlight and brake light is far more magnificent due to the
performance of this race prepped engine with 36 mm Del Orto's!
She truly performs as well as she looks.
Ducati 750 Desmo Spaggiari styled motorcycle was built for
spirited riding on the street, we made our own wiring
harness/loom and use a modern, more reliable fuse box and
voltage regulator. Our philosophy is to keep the soul of the
vintage race bike but upgraded with modern components for safety
and for reliability purposes. I have the original items if you
prefer. For states or countries that require turn signals, the
clip-on's are wired for Bosch style bar end indicators that can
be seen at the front as well as the back of the bike. A set of
these bar end turn signals is included.
conclusion, this is a fully restored Ducati "Round Case"
motorcycle and with a "Blue-Printed" desmo bevel drive engine.
The engine has run long enough for tuning of the carbs and for
one test ride. Other than that, this is as new as one can get
with a motorcycle that was originally built in the early 1970's.
Steve at Bevel Heaven can speak to all of the new parts that
were purchased from him to do this restoration and he can be
contacted at 925-798-2385 and Malcolme Tunstall can speak to the
full engine build and he can be reached at 727-522-3333. This
machine carries a clear, valid US title for Arizona. Will work hard to make shipping of this magnificent machine to
your location as easy as is possible. Feel free to visit the
bike here in Arizona.
From Steve Allen: The photos shown above show vast
differences in color tone from photo to photo, some looking WAY
too dark orange... So I asked Scot to find a photo of the bike
along side another Sport to compare colors.... The photo
above shows this Desmo along side the other Sport currently
offered for sale and as you can see the color is spot on....
Scot has owned several Sports and believe me, he knows the
appropriate color tone and this is it.
Of course, nothing beats The Original - here is the
inspiration for this bike at The Ducati Factory.
