From the July 1935 issue of Motorcyclist Magazine
Up and down the reaches of the grapevine communication system of motorcycling the question has gone. “When is Indian coming out with their new four?” Supporting the question have been choice morsels of information, some correct and many incorrect. However, whether or not the information was authentic it all tended to bring out one thing; motorcyclists were interested in a new four-a new aristocrat among two-wheelers.
Now the four is a reality. It has officially been announced by the factory and complete specifications are given as appear herewith. With the four just released for, sale, not much opportunity has been available for trials, except on the East Coast. So we can’t relate, except by hearsay, how it feels to uncork the new job. What we can do is pass on the reactions of two well known men in the fraternity, who have inspected the new job. One from the East Coast is that oldtimer who is known all over the country, Fritzie Baer. The other, from the West Coast, an equally well known oldtimer, Hap Alzina.
Not so long ago these gentlemen formed a committee of two to take out one of the fours and put it through its paces; not just for a short speed trial down a smooth highway, but through all the variations of a considerable piece of Massachusetts’ countryside. They coddled it and they punished it. There were bursts of high speed and then a quick stop to listen. And when they came back it was hard to tell which was the broadest, the Baer smile or that of the Haperino. “And, she’ll cruise at ninety,” says Hap.
For a thorough analysis of the machine it is but necessary to carefully review the specifications. In doing so note that there are a few departures in design, which after some little testing, are being incorporated. The new job includes a special carburetor of updraft air valve type with three compensating jets designed to give more power; heavy duty cylinders with extra large cooling fins; high compression combustion chambers; increased lift on cams; enlarged porcelain finished exhaust manifold with double free action mufflers; needle bearings in rocker arms and a continuation of the choice between magneto or battery ignition.
In addition to the above features the new four has been given a lowered center of balance. Oversized braking service and a new centrifugal action clutch, combined with all the other features tend toward an apparent combination of comfort and safety in the new outfit.
Fours are rapidly being distributed all over the country. After all the best way is to see, to try and to learn. So drop in at your dealer’s and see for yourself. The four is here.
