1951 SUNBEAM S-8 TWIN CYC.  CORRECT BIKE WITH ALL ORIGINAL PARTS. STARTS EASY AND RUNS GOOD. I HAVE RIDEN IT AROUND TOWN AND A COUPLE OF ROAD TRIPS. IT RUNS GREAT, SHIFTED SMOOTH, IDLED GOOD. THE PAINT IS OK BUT NOT A SHOW BIKE – IT’S A RIDER, I HAVE TOUCHED UP A FEW TINY SPOTS.  ONLY NEEDS A NEW BATTERY AND IT’S READY TO RIDE. I'M SELLING IT BECAUSE I HAVE CANCER. I HAVE A CLEAR UTAH TITLE FOR THE BIKE. THE WARRANTY ON THIS BIKE IS LONG OVER AND IT IS SOLD IN "AS IS" CONDITION.

 The Sunbeam S8 are British motorcycles designed by Erling Poppe with styling loosely based on the BMW R75 designs that were acquired as war reparations by BSA (full rights to the Sunbeam brand had been acquired from AMC in 1943).[1]Built in Redditch, the unusual engine layout was similar to that of a car. The engine was a longitudinally mounted inline vertical OHC 500 cc twin based on an experimental 1932 BSA design (the Line-Ahead-Twin - LAT)with coil ignition and wet sump lubrication which, though a dry clutch, drove a shaft drive to the rear wheel. The inline engine made this technologically feasible—horizontally-opposed ("flat") twin engines on BMW motorcycles had already used shaft drives.
