Harley-Davidson 1934Â Model âRLâÂ 742 cc side valve V-twinÂ engine # 34RL 1158 For the 1932 model year a redesigned 750 was marketed as the Model R. It differed in many respects from the previous model. To name a few: new cylinders, flywheels and conrods, crankcases, cam gears and oil pump, plusÂ many more detail changes in the engine and cycle parts. Unfortunately sales were very slow in 1932 due to the worldwide economic depression. No more than about 1,300Â model R bikes were sold that year. In 1934 the economical situation had improved slightly, witnessed by the 2035Â R series machines that were sold that year. The R was available in a number ofÂ versions, the âRLâ referring to the medium compression models. The RL had a 5:1 compressionÂ with a power output of 18.5 HP @ 4,000 rpm.Â Cosmetic changes for 1934 included an Airflow tail lamp, new tank graphics with flying diamond design andÂ (this year only) upswept Hi-Flo tailpipe.Â Technical novelties were improved low-expansion pistons, a new oil pump and a strengthened clutch. This fine restoration is presented in a very tasteful colour combination and comes complete with Corbin speedometer.
