This bike has many unique features including a tachometer driven off of the oil pump. It has a hand built rear frame section from Chromoly steel.

This bike also is one of only two bikes still in existence with what is known as a four cam set up. It is actually two cams with four lobes. Dick used this configuration to dial in the cam timing to a much closer degree tolerance. Included with this bike is Dick's own note book where he jotted down the cam timing for Bobby's 1952 Springfield Mile race, which he won.

At that time if you won that race you became National #1 and carried the plate for the next season. Bobby Hill won in 51 and 52 thus carrying the plate in 52 and 53. Bill Tuman won in 53 on an Indian, and carried #1 in 1954. He was the last racer to win the #1 crown by winning at Springfield.

Many pieces of memorabilia including Dick Gross' own racing jersey, original framed racing posters, photos, newspapers, and note books are shown below. Also, a box of original cams including "four cam" set ups and hand ground followers. An extra 648 cam cover too.
