The Weirdest Engine I’ve Ever Worked On Puch SV175 Twingle #vintagemotorcycle #motorcyclerewind #twingle Join this channel to get access to perks: https://www.youtube.com/channel/UCXCVqILEkluYk5J4oXNabkA/join In today’s episode of Motorcycle Rewind, we take a deep dive into one of the strangest motorcycle engine designs ever made — the Puch Twingle engine found in the Puch SV175. This isn’t your typical 2-stroke. This engine features two pistons inside a single cylinder, working together to control intake and exhaust timing. It’s a completely unique design that was meant to deliver smoother power and better low-end torque compared to traditional 2-stroke engines. We’ve got three engines to break it all down: The original engine (with a busted case) A complete replacement engine going back into the bike A top-end-less engine so we can actually SEE the twin pistons in action We’ll: ✔ Show how the twin pistons move independently ✔ Explain WHY Puch designed it this way ✔ Compare it to traditional 2-stroke and 4-stroke engines ✔ Take a close look at the unique oval-style cylinder bore ✔ Talk about Sears Allstate models that brought these bikes to the U.S. If you’ve never seen a Twingle engine before… you’re in for a treat. This is one of those “they don’t make ‘em like this anymore” designs. #motorcyclerewind #puch #twingle #2stroke #vintagemotorcycle #enginerebuild #barnfind #mechanicaloddities Thanks for watching Motorcycle Rewind. 💬 Join the channel to support Motorcycle Rewind and get early access, badges, and behind-the-scenes perks. 🛠️ Subscribe to Motorcycle Rewind for more revivals, adventures, tips, and stories from the garage.
