FRAME NUMBER : Z1F - 00041

The history of this bike is extraordinary.
The machine is Z1F-00041 serial number.

It is part of the first 101 series machines assembled in the month of August, 1972 : particularity, the engine block of these bikes has the same number as the framework.

In 1988, this machine was still in the U.S.A. It was bought to be brought back to France where she underwent a certification as isolated and... a first partial restoration.

At that time, the restoration of the Japanese bikes of the seventies was rare and complex : it went first to the dealer of the brand to order yet available spare parts catalogue.

« We have made KAWASAKI 900 cc “' Super 4” for experimented  drivers who feel avid and able to acquire a larger and more powerful than the other... motorcycles »

« It reflects the confidence of Kawasaki in its future owners who will use it with common sense and courtesy. »

General Manager division motorcycle K.H.I.
September 1972

Generally on this occasion that it understood the meaning of the word 'balance': one could for example order 4 exhaust of origin (4 separate references) only to receive, in general a few months later, as part of the order, in this case, one, two or three mufflers, the rest of the order being placed in balance.
And the balance could still last for months...

Difficult under these conditions to restore full and consistent...

2Once restored, Z1F-000041 was the subject of a story in the magazine MOTO  1 (No. 119, March 1993) :  motorcycle magazines in the Japanese collection were not legion at this time!

The bike has almost never worked, she joined a private collection where it is left exposed during fifteen years. It was there that I saw her for the first time, innate in the middle of a multitude of Suzuki of the 1970s.

In 2008, a fire destroyed this collection and the building that housed it.

Like most motorcycles that surrounded it, the Z1F-000041 partially burned and buried under the rubble following the collapse of the structure and the building floor - bikes were in the 1St floor.

Motorcycles as the rubble have then been cleared using lifting gear causing damage to the Z1F-000041 framework...

It is after these events and at the end of the procedure which followed, that I got this machine, or what remained.2E restoration work began.
After three years of work, the machine is finally over.
