The Kneeslider just passed its 7 year anniversary and one of the most enjoyable benefits is getting to see the progress some of the projects we covered years ago have made since we first brought them to your attention. I just received an email from J. Jacek Synakiewicz, he’s the JJS in JJS Design, the Polish company behind the JJ2S X4 500 we wrote about way back in 2008. He wanted everyone to know they’re still moving forward and have a prototype under construction which was just exhibited at “Design in Poland – Transition to Modernity” in Geneva, Switzerland.
For those of you just tuning in, the motorcycle is built around a 4 cylinder, 500cc 2 stroke “X” configuration engine, sort of a 4 cylinder radial. The previous computer renderings looked great and the bike now under construction by GG Tech looks every bit as good, which means the photos are quite amazing.
JJ says their goal is to have the bike finished some time next year so it can be displayed at one of the major European motorcycle shows.
This is one of those projects that just looks so cool and has such neat technology you really want it to succeed. Right now they are looking for investors to help bring it all together. I hope we see the finished bike next year wowing the crowds all over Europe.
UPDATE: I’m adding this animation below to show how the X4 moves.
The translated version of how it works is here.
