Biggest Single Cylinder Engine. 2000 CC

Franz Langer is a retired engineer living in Germany. His passion/obsession? Building the world’s largest single cylinder engine for a motorcycle. He started with an airplane engine and fitted inside a bigger and yet lighter piston.  The result is a 2000 cc engine that he mounted onto an old NSU Konsul getting Franz name added to the Guinness Book Of World Records. The quite funny part is that the bike uses a kickstart. To start it, you are better off weight more than 200 pounds and have a lot of time front of you, like being a retiree.

    Well now, this looks kinda fun… wonder what kinda horsepower this this makes? I’d love to hear what it sounds like too.
    Hey Cyril, could you find out if this guy has a video with sound so we can see/hear it run?

    With a kick start I hope he has a good knee surgon on call.

    I’m an engineer and most of my bikes are kickers. Although not that big. My hardest K start bike is a 600 thumper. Way harder than stroker HD’s. Can’t imagine what a 2000cc thumper’d be like…

    hey this bike looks awsome but surley the weight of the piston would shake it around a bit and it would be near impossible to start, i mean ive got a 400cc two stroke and thats a pain in the ass but this i mean seriously… i hope someone comes up with a vid..

    He has already built a 1000cc one but others were about to overthrow him this is the ultimate statement. Mind there is always the guy who put one V of a merlin engine in a bike frame i believe about 5.600 Ltrs
