"Quasi Moto" sounds cooler than Nembo as well. The article raised (or lowered? ) this point... Why upside down? Well, if you ask the Nembo team, it's inspired by early aircraft engines and done in service of mass centralization. Keeping the center of mass low, in Nembo's estimation, is less important on a motorcycle than keeping it tight. With a rider on board, the best way to keep the bulk of the mass in the smallest possible circle is to flip the motor over and put the crank at the top, with the lighter cylinders below. Which is along similar line of thinking as to that which this bloke and co. came up with when they invented the 70 degree FE Husaberg motor... as BergDonk refers too above. Thomas Gustavsson... in many ways, the "Swedish" godfather of the modern fourstroke enduro motorcycle... all are his brainchildren... Husqvarna (were still Swedish back then) 510 TE fourstroke The "original" Husaberg: from a little factory in the forest - "Rofors". The ground work for Joel Smets factory World Championship MX Husaberg/Vertamati's came from Rofors - and fourstrokes came of age (again) in motocross. Enduro EM, WEC Championship and ISDE medals followed... 2005 Husaberg acquired completely by KTM: They turned the World "upside down" with the FE 70 degree motor design... and Thomas remained the Husaberg factory enduro team director/manager - right until the "HUSABERG" marque was dropped by the parent company... A great rider in his own right (former Europe Champion and ISDE gold medallist), a brilliant (practical skills) engineer, a great manager/motivator and a terrific bloke to boot... TG did so much for the fourstroke enduro bike - as we know it today - yet, outside of his hometown, and enduro circles in sweden... he is a relatively unknown profile... ... just thought I'd share that with you.
