Doers Builders and Positive People

Twin Turbo 4 Liter BMW V8 Powered Proboost M1

By Paul Crowe

Twin Turbo BMW V8 Powered Proboost M1

You can build a motorcycle for a lot of reasons, sometimes there's a theme or style like a cafe racer or maybe a street tracker, but other times a builder just does what he wants and that's what we have here, the Proboost M1. I noticed it while looking over the bikes for sale and it made me smile. It looks like it was built to highlight the Proboost Turbosystems business so the … [Read more...]

1980 Egli Turbo Kawasaki Offered for Sale

By Paul Crowe

1980 Egli Turbo Kawasaki

In a world of constant internet auctions, where everything is available for sale, where rarity itself is, well, rare, a few motorcycles still hide away, known to a few, but rarely if ever seen and certainly never offered for sale, then, out of the blue, one pops up, a 1980 Egli 1MRD Turbo Kawasaki. Eleven years ago I wrote about one of these, referring to a Cycle … [Read more...]

How To Drive and Steer the Same Wheel in a Two Wheel Steering Motorcycle

By Paul Crowe

Split hub center steering drive wheel on Bob Horn's recumbent racer

Last summer we showed the latest version of Bob Horn's recumbent racer with two wheel steering. If you're new here, Bob's race bike is his own design and entirely scratch built and when you decide to incorporate 2WS, you can't just look around to see how everyone else did it and choose the method you like best, because recumbent 2WS race bikes are non existent.

It all started years ago, in 2009, when we featured a series of Solidworks CAD drawings by Ian McElroy for a concept motorcycle called “Kickboxer.” The idea was to create a radical, but carefully planned design using the 2.5 liter engine from a Subaru WRX. The drawings were a big hit and quickly made their way all around the world until a friend sent one to Marcel van … [Read more...]

BMW K100 Custom – A Gentleman’s Express by Alex Zemlin

By Paul Crowe

BMW K100 Gentleman's Express by Alex Zemlin - from rescued cafe racer project to canyon carving comfort

Alex Zemlin has been on The Kneeslider twice before with his Honda CB 1.5 and then again with his VTR 1000 Super Hawk GT. In both instances, his work displayed that finished factory look, where many miss the amount of work done until a closer look begins to reveal the truth. His attention to detail is apparent everywhere and his build quality is top notch. He's still … [Read more...]

Chris Barber’s Maserati V6 Motorcycle Project is Underway Once Again

By Paul Crowe

Maserati V6 by Chris Barber

It was almost four years ago when I first wrote about the beginnings of Chris Barber's Maserati V6 project. I hadn't heard much about it since, but Chris dropped me a note saying he, too, had taken a break, but he's back at it now and I'm really happy to hear it because this is a great build. Chris first caught my attention over ten years ago when he built the AlfaBeast, … [Read more...]
