From the desk of Connie Constantine KJ did the gorgeous model, presented in public in April 1929 and generally acknowledged by the admirers of Henderson as the most beautiful specimen of all produced by American home.
The line of the upper frame tube was nearly straight, from the top of the fork to the rear axle, adopting a triangular tank for fuel, that staying on top a group of very complete control instruments, consisting of a speedometer, an indicator of oil pressure, ammeter and a switch to electric lights.
The front fork was not the type for lower links to wheel spin, but wheel driven, and mounted a front brake drum and shoes floating.
But the real work of art was the KJ engine, completely new: although the displacement of 1,300 cc had remained motionless, crankshaft bearings going to be five instead of three previous model.
The valve assembly returned to the original solution intake valves and side exhaust head … all in all, as the company claimed, these innovations constituted about 57 improvements.
