The frame geometry
is the result of countless laps at the Varberg Monark test
track. Sten worked very closely with the Monark engineers to
come up with these specs. This is the original frame made in
1960 at the Monark factory. In those days you repaired the
original frame if something broke and this one was no different. If anything got
bent or flattened, it was repaired. The massive gussets that run
down the length of the front down tubes were put there by the MV
Agusta road race shop after Sten broke the frame at an
International race in Gallerate Italy. Sten did have an idea to
lower the motor and a frame was made to test his idea. After
testing the lower model, it was decided that the original frame
was better.

These forks are the
first ever Ceriani motocross forks. After Ceriani made these
forks for Sten, they went on to produce front forks for many
production bikes. This particular set is all hand made and the
internals are all machined from billet aluminum. The stone chips
in the lower sliders from all the years on the Grand-Prix
circuit are still there.


The front hub was made by Pranafa and had a lot of
stopping power. Ceriani combined the forward axle lug to the
front backing plate stay all with one piece. A special front
brake arm was made that wrapped around the right fork slider.
This front wheel was used in 1960 and 1961 but Sten opted for a
smaller conical hub in later years.


Several sets of triple clamps were made
(in Italy with the forks) and tested offering different
off-sets. Sten settled on a parallel set with a 36mm off-set.
You can remove the entire set (top and bottom) with out removing
the steering stem. Check out the massive steering head. You can
see the stamping in the top clamp written in Italian.



The swingarm is very special and reduced
unsprung weight was the goal here. It is made from the highest
grade Swedish chrome moly tubing available at the time and the
tubing is tapered for less weight. The chain adjusters are very
unique and all handmade from billet. Very trick parts!
The rear brake uses a wire instead of a solid rod. The wire was
chosen because if another bike happened to hit it during a race,
it would go back to it's original form whereas a rod might get
bent and cause the brake to lock up. Much thought and attention
was paid to every detail when designing this bike.

A massive conical rear hub connected to
the rim by 40 spokes features a British Dunlop 400x19 inch rear
tire that was responsible for putting the power to the ground.
Rear shocks are Girling and the pipe has no muffler. The sound
that this bike makes has to be heard to be believed.

The rims were made by Dunlop in England
out of a very strong and light weight tensile steel. These rims
were very expensive to produce and were for factory riders only.

The handmade foot pegs mount to the frame
and the engine cases with large bolts and have non-slip cleats
made from weld. Note the small tab welded to the left peg to
keep the brake pedal from bending out. The right peg is nicely
cut away to allow the pipe to go through. Everything on this
bike is very compact and well thought out.


The fuel tank is completely hand pound out
of sheet aluminum as seen by the hammer marks on the surface.
This tank was used in every race that this bike competed in.
Lito made a special tank sticker just for Sten with the tallest
building in Helsingborg inside the "H". Helsingborg is the city
where the Lito factory was located. The tank was held to the
bike with the strap in the picture below. This is the same strap
that broke at Namur Belgium in 1961.


The original green paint from 1961 can
still be seen inside the tank.

The aluminum bar that is bolted across the
bottom of the tank is there to keep the tank from splitting due
to the vibration from the motor. The bar was not there at the
infamous race at Namur when the tank came loose.

The
handlebars are an original set that Sten himself made back in
1961. How many riders actually helped make their own bike?

The Lito was restored and signed by the
Champion himself.
