Enigma 1050 – Brand New British Motorcycle May be Available in Both Ready Built and Kit Form

By Paul Crowe

Enigma 1050 - all new British motorcycle

If there's a constant on The Kneeslider, it's our preference for seeing projects being built, when people decide their ideas are worth the effort and actually make them happen. This brand new British motorcycle, the Enigma 1050, is our latest example. Jim Lindsay, the man behind it all, sent us the background to how it came about.

Kwikasfaki GSX-R400 Kawasaki H2 750 custom

By Paul Crowe

T900 project computer mockup

When we last looked in on John TangerÃ¥s, he showed us the beginnings of his T900 project with lots of 3D printed parts for fitting and mold making plus some initial machining. He's been working steadily, but anything of this magnitude and complexity takes a lot of time. He's continuing his engine work with the intention of finishing that first instead of having half finished … [Read more...]

By Paul Crowe

Harley Davidson Penster reverse tilting trike

Remember the drawings for the Harley Davidson Leaning Trike Patent we showed you way back in 2007? Well, the Harley Davidson Museum takes the wraps off of the real trikes (code name "Penster") behind those drawings.
