Henderson 1931 KJ 1301 cc 4 cyl ioe



Henderson   1931   “ KJ Streamline”   1301cc four cylinder frame # 3298  engine# KJ 35722

With the phrase “ a new one from Detroit” the Henderson factory introduces its first production model in November 1911. 
To underline its qualities Carl Stevens Clancy sets out on a journey around the world with a Henderson four, covering a distance of 18,000 miles. 
From the 1912 model on yearly improvements are made in the design, which eventually result in the model KJ, which is announced to the public in April 1929.
It  is  dubbed  “ the streamline Henderson” because of the graceful lines of fenders and petrol tank. 
The smooth-running KJ has a  five-bearing crankshaft to replace the old three-bearing one, new design cylinders with heavier finning, new unit valve cage design with overhead inlet valves and a down-draught carburation system to name some improvements.  
On top of the tank an  elegant instrument cluster is placed.  
Due to the economic depression Henderson motorcycle production ceased in 1931.

A  KJ puts out 40 BHP@ 4000rpm and is capable of a 100 mph top speed. 
The KJ is an extremely flexible motorcycle: it will accelerate in top gear from 10 to 100 mph. 
This KJ is an older restoration and is running fine.
