2007 C1 990

2007 C1-  the white paper

The '07 was the first 100% MotoCzysz motorcycle; proprietary chassis, suspension and engine.  To hold all the parts, then build, and finaly hear the engine you have been dreaming about for years is a type of birth.  I do not know the number of men that have experience this but I suspect in this day and age of giant engineering teams it is a small club- and still one of my proudest moments.  The bike had grown a little as the '06 was deemed too small and compact.  The rough sound had been replaced by a truly unbelievable, fierce sound, a mix between a Ducati and a F1 car.  It screamed like nothing any of us had every heard before or since.  The sound was loud, powerful and determined below 10K and above 10K?  Louder, more powerful, above 14K?  Down right frightening.

Worst moment

Early days, corner entry.  The first version of the 990 had a very strong torque characteristic, both on and off the throttle.  The reality was, excessive engine braking was caused by parts that were slightly out of spec, engine assembly techniques that were imprecise and less than perfect oiling, the result?  Roll off the throttle and the engine felt like it was on the verge of seizing followed by serious rear wheel chatter, then blurred vision

Greatest moment

Every time we started the engine, every time.  Chills...
