1975 works 250 Puch Twin carb
Harry Everts - Four Time World Champion
1975 250 World Championship Bike
Harry Everts 1975 Works 250 World Championship Puch. There were a total of four bikes built, two for Harry and two for Herbert Schmitz. Also, two spare engines were built, one for each rider. Each bike was completely hand made.
Today Harry's bike sits unrestored just as it would if it was prepped for a race.
About 90% of the fasteners are made from titanium. This bike was the lightest bike on the 1975 250 GP circuit.
These Marzocchi magnesium works forks are very light and very rare. Only a handful of sets were made, and because of this they were interchanged between bikes.
Sandcast magnesium wheels with titanium hardware.
Not much steel in this photo.
Puch engineer Hubert Binder was the designer of the twin carb 250 engine. The idea was one carb piston port and one carb rotary valve. One for low end and one for top end power. The idea worked but the main advantage was at the top of the range. Harry was OK with this as he mainly rode at the top end all the time. Note the kick lever: It is hand machined from billet titanium.
Hubert Binder spent a lot of time working on this engine and got an astounding 52 HP on the factory Puch dyno. Harry talks about passing 4 riders in one straight at a race in Belgium. It was easily the fastest bike in 1975.
52 Hp was over 10 HP more than what the factory sold the public that was still rated at an incredible 40 HP.
Each carburetor is 32mm and each is jetted differently.
The 1975 works engine differed than the replica with different crankcases, crankshaft, gearbox, ignition, cylinder and pipe. Othere than that they were close. Puch even experimented with a titanium crankshaft. This titanium crank is also in the IMM collection and will be on display with the bike.
Shift lever is made from billet titanium.
The chassis layout and suspension were excellent in 1975.
Works Koni shocks were made just for this bike.
Special handlebars were made just for Harry. Harry could adjust the clutch on the fly with the magura levers. Triple clamps are sand cast magnesium.
The description on the crate says it all.
Taking the cardboard off the crate revealed and very special one of a kind motorcycle.
