Nice. Never seen one of those before. Probably because it´s Austrian and pretty rare in the rest of this planet. Also they stopped producing bikes a looooong time ago  |

Sears rebadged them as all states back in the day. In America If I recall it's a triangle engine..2t

What is the project? Unless you need help placing it in your living room? Look ready to show!

One popped up on CL here a few months ago as an Allstate. Interesting scoots.

In '66 Sears stopped importing all manner of two wheelers as the Asian bikes were making inroads in the US. The engine is known, or has been referred to, as a "Twingle". It's 250cc twin cylinder with a single head. Very interesting configuration and is a 2T. BTW, James Dean road a smaller version on the set when making the mid-50's classic "Rebel without a Cause". His was a 175 cc PUCH.  |

You have done a great restoration on that. Are bits still easy to get hold of?

This is my 250 "Twingle". I pulled it apart to check the condition and clean her up. Motor looks great inside, now just have to build a chassis to put it in!  
The port timing, like all two strokes is controlled by the pistons, but this is crazy, the rear cylinder handles intake, the front cylinder exhaust, with a shared combustion chamber and shared crankshaft. the real beauty of these is the pistons are timed to completely shut off the intake and exhaust, so no scavenging or exhaust waves to consider (no expansion chambers here) this limits horsepower, but gives the bike a solid 70MPG and mush cleaner emissions, as well as a 2 stroke with a four stroke like power delivery, and very reliable, long lived motors. |
