This 1926 JD is powered by a 1000cc side valve (IOE) V-Twin, breathes thru a Schebler Delux and power is run thru a 6 volt system. The only braking is on the rear wheel by an external band contracting around the drum. (front brakes were introduced in 1928). Hand gear lever and foot operated clutch engage the 3 speed transmission. I restored the JD back in 1997 and she resides in my collection and displayed at numerous bike events througout the year.
