The Servi-Car was designed for the road conditions of the day, where surface roads might still be crude and unpaved. It has a rigid rear axle with a differential. The rear axle had a track of 42 inches which was similar to the track of most available cars. This was done so that the vehicle could use the same tracks that had been made by regular cars. The Servi-Car uses Harley-Davidson's "W" model 45 cubic inch flathead. Which was upgraded from the "R" Flathead model by mainly having a recirculating oil system instead of the constant-loss system of the "R". The "W" flathead engine continued until the end of production in 1973. Until 1957, the front forks of the Servi-Car were the springer-type leading-link forks used on the R-series and W-series solo motorcycles. This motorcycle has 0 miles since the restoration was completed..that's right ZERO miles. This gorgeous bike won't last long so call us today!
