Here a little bit Demon history...
We started up in 2006/2007:
Last winter we decided to develop a new Ducati 2V project bike. Our partner in Denmark, the Italian Bike Store/Haasum MC, had the same idea and so we started with the design in october 2006 for two bikes, one for Haasum and one for us.
We thought that it would be a nice idea not to go for a classic design, different to all the other newer bikes. We concentrated on a new center weight with more front load on the wheel. So at last we fitted
into the center of the
chassis, directly under the stearing head. So deep, and as far ahead as possible. The result is a perfect weight balance.
The season before we raced an equal bike with the Testastretta engine and built a special exhaust system for this bike. The same
is now used again with the 2V engine. The special thing on this exhaust system is that the tube length are absolutely identical. One tube is placed under the the seat and the other under the engine. That means also a very good weight balance and with the identical tube lenght also the power will increase.
The temperature of the vertical cylinder made us some headaches but we have found out a wonderful optical and technical solution with using a
. The air stream from the side panels is cooling down the heat. It is very surprising that after one year of continuous measurement the vertical cylinder is 10 degrees cooler than the horizontal.
We run the bike with a
and an
. This system is fully programmable and very flexible.
The cylinder heads are equipped with self designed camshafts and
and
. Standard sizes are 45mm and 40mm.
Bore size of the cylinders is
. Different power types are available, please take a look at the diagrams. The total beginning weight is 138 Kg!
These motorcycles were in the 2007 season very successful. Our danish partner joined the Sound of Thunder class at the Ducati Club Race at Assen/Netherlands and reached two 13th places of 45. A brilliant result when you know that all the bikes in front have 160-180HP (1st had 205 wheel HP!) We started racing our Demon at first at the Festival Italia in Oschersleben/Germany. Italian Bike Store also and they got 1st and we 2nd. At the Biketoberfest in Oschersleben/Germany we got 2nd again. Laptimes in Assen are 1.52 minutes and in Oschersleben between 1.35 and 1.36 minutes with a normal rider. Ago Rosivall started with the first prototyp demon 1100 with 1.32 !!!!
in oschersleben !!!....
It was (in theory from Laptimes)the 2 second start position in "sound of thunder" where only biggest 4 Valves bikes 1098Rss aso. are starting.
In pannonia he goes 2.01 with this bike , it was in "open biggest category" there in theory 4 th place start position in 2008,speed week.
Lex van dyck goes two times 7 th place in biggest class "sound of Thunder" in Assen Clubrace 08 !!!
So consistently successful and very fast for a 2 valve motorbike in the first year.
We will continue...
