Dennis Franz Builds a V8 Motorcycle with a Glorious Soundtrack

By

We first wrote about Dennis Franz way back in 2010 and again in 2013. His V8 engines were amazing little builds, but he's come a long way since then. I hadn't been watching him for years and while I was looking at another engine on the web I came across a later build, though it's several years old, as well. The sound of a Vmax with a good exhaust is often compared to a small … [Read more...]

Engrich ART Motorcycle with a Fully Balanced 360 Degree Parallel Twin

By

Here is another example of superb engineering from the land of the Kiwi, it's the Engrich ART (Appel Richardson Twin) motorcycle, powered by a fully balanced, 360 degree, 1200cc parallel twin. There's so much to look at here, it's difficult to know where to start. You might think this is a beautifully designed upright standard motorcycle, and it is that, but upon closer … [Read more...]

Omega 1 Internal Combustion Engine is Light, Powerful, Efficient and Clean

By

The Omega 1 from Astron Aerospace is a brand new internal combustion engine concept and I really mean brand new. When I first looked at the images, I couldn't figure out what was going on.

It's pretty ingenious, but you … [Read more...]

Bistella 500, a 500cc 2 Stroke, 2 Row, Supercharged, 10 Cylinder Radial Engine Custom Motorcycle by Marek Foltis

By

Let me get right to the point, this engine build/custom motorcycle by Marek Foltis is one of the most impressive homebuilt projects I’ve seen since starting The Kneeslider in 2004. It’s that good. It began when Marek challenged himself with almost impossible goals, followed by absolute personal commitment to learning and doing whatever it took to get the job done. This project … [Read more...]

NCCR Developing a Buell SuperSingle Based on the 1125 and 1190 V-Twins

By

Swedish Buell specialist company, NCCR, is currently working on a new SuperSingle engine based on both the 1125 and 1190 versions of the Buell Helicon V-Twin. Using the same concept as seen in the Ducati Supermono, they remove one cylinder and in its place install a pivoting lever that connects to the connecting rod for that cylinder, providing balance previously provided by … [Read more...]

Rimar Motors 600cc 2 Stroke V-Twin Project

By

Rimar Motors, in the Netherlands, is in the advanced stages of machining and assembling a 600cc 2 stroke, V-twin engine, designed to be installed in a 2004 Aprilia RSV1000R frame. The project has been going on for about a year and they've put up detailed photos of the entire process. The engine uses reed valves and two counter-rotating crankshafts. Cylinders come from a … [Read more...]
