Hard to find for sale and always desirable, the Indian inline four cylinder is often the highlight of any American motorcycle collection.
This 1939 model is fully restored and has only 5700 miles on the restoration. For 1939, the Indian four had a rigid rear suspension with trailing-link forks and quarter-elliptic leaf spring up front. It's equipped with a 6 volt electrical system.
The seller didn't supply many specifics, probably because it's being sold by the son of the owner that did the work. Serious potential buyers should ask questions before bidding. It's for sale on eBay.
