The nail in the coffin of split singles was when Jawa introduced the world's first transverse ported 2 stroke motor in 1946. A transverse ported 250 2 stroke produces more power and torque than a 2 stroke split single of the same displacement. It can also be made to rev higher, hence why the split single 2 strokes became a dead end branch on the 2 stroke evolutionary tree.

The pre-war Trojan car, designed by Leslie Hounsfield, used the split single, but had two of them, making it a four cylinder split single twin (Eek!). It also made do with two (vee-shaped) connecting rods, meaning the rods had to bend with each crankshaft revolution, thereby leading to a four cylinder car engine with only seven moving parts...... my head is starting to hurt. They were so quirky that apparently many garages used to display signs reading "No Trojans". Hounsfield later set up a company making camp beds, which surly shows something. Trojans advertised their cars with the slogan "Can you afford to walk" after working out their cars were so cheap to run that over 200 miles shoes and socks for the same distance would cost more. Their motors could be tuned up and, in much the same way as Stan Stevens was known as the Yamaha LC tuning guru, Trojans had a tuning expert by the name of Scroggs, a Group Captain in the RAF; getting the engine to go faster was known by Trojan owners as "Scrogging" the motor. I assure you I am not making any of this up.

Excellent choice in subject matter, Keep up the good work this wasn’t easy to find these bikes. My family had a motorcycle dealership, Bsa and Bridgestone, the Bridgestone 175 cc what is a twin, stock edge crank stroke was 180 between the two cylinders, but they would twist the crank until both pistons ran 360, and they called that a twingle, They did this for better traction in the dirt, less power pulses through the drive system.

0:07 The second cylinder does not suck, the mixture is pushed in by the crankcase pressure! What's more some split singles have pistons that are rising and falling at the same time, e.g., the TWN split single. TWN Cornet: compression ratio was 6.5 : 1. The SS250 DKW had more than 20 hp, approx. 25 hp.

You missed a Huge seller, the 175 and 250 Twingle sold by Sears as a Allstate from the early 50's to the late 60s. They were made by Puch. The cylinders were in sync as there was a master connecting rod with a tab off to the front for the slave cylinder. Neat thing was with my 175 cc unit the porting for the rear cylinder was different than that of the front cylinder. Did some 2 cycle performance work over the years and it was one was ported for low end torque and the other for higher end torque.

I think twingle also exist on four strokes but differently. Its a parallel twin that has both pistons on the same height all the time, but not like usually firing every other stroke (every 180deg), they fire at the same time every 360deg. There even was a kawasaki 1000cc 4cyl race bike that had 2 cylinders fire at the same time lol

In the 60s I had a puch sport model with the twin carbs, one either side. They were cheap and ugly, in Austria. Always hard to start and usually had to push start, like the guy in the video. The pistons work like a 2 stage compression, the back one being a little behind the first, being the power stroke. Both pistons were on the same connecting rod. Never impressed me.

It is and it isn't. The single combustion chamber saves metal and machine time versus two. The second cylinder reduces the need for an exhaust expansion chamber making exhaust engineering and manufacture cheaper. The Allstate was meant to be a cheap commuter to slog through urban traffic. Lots of idling, lots of stop and go, and little high rpm running. In that role the twingle makes some sense. YPVS and Reed valves were still on the horizon.
