Maarten Janssens is Building the MJ Works Racing Supermono

By

Recently, I got a note from Maarten Janssens, you remember him, he's the student who designed and built his own 250cc racer from scratch. Some of you commented the work he did on that project was a strong indication we might be hearing more from him and, sure enough, his first racer was just a warm up. Maarten just turned 22, he's still studying, but after the first bike was … [Read more...]

DIY V-Twins From Unexpected Places – the Home Made Junak 700

By

Up until the moment I received an email from Kim Scholer, I had never heard of, or at least don't remember ever hearing of, a motorcycle manufacturer by the name of Junak. According to wikipedia it's a Polish marque, built from 1956 to 1965, though it seems there are some later versions, perhaps the company was bought and restarted? The old engine was a single cylinder … [Read more...]

DIY 1000cc V-Twin 2 Stroke Project

Then the really rare fellow says, hmm, ... ya know, that's not a bad idea. This project, currently under way in a long build thread over on the PBmag forum, is still in progress, but the photos … [Read more...]

OV-23XV Air Cooled Yamaha Big Twin Racer from Over Racing of Japan

By

Curt Winter's big twin racer sparked a discussion about big twin racing in general, it seems quite a few folks think it would be a Harley Davidson series and of no interest to anyone else. Doug dropped a link in a comment to this sweet looking machine from Japan's Over Racing, it's the OV-23XV, built around the 1670cc air cooled V-Twin from the Yamaha Warrior and MT-01. To me, … [Read more...]

Francesco Romanelli and His Amazing Designs

By

Who is Francesco Romanelli and why haven't we heard more about him? That's a question that popped up in my mind as I browsed his website the other day, following a tip from one of our readers. The name sounded familiar and we had an article on The Kneeslider a few years ago about his anti-turnover system designed to prevent wheelies from continuing until you flip over … [Read more...]
