Have a look at the handling performance of the 4MC. A leaning four-wheel bike that offers superior leaning suspension patents. The designer, Nick Shotter has been refining the engineering for the past 20 years. Yamaha offered developmental support & equipment prototype construction but did not 'buy' the IP for sale or license. In fact Yamaha tried to incorporate 4MC's ideas to it's own Tesseract prototype but was denied by the European Patent Office because it was too similiar to 4MC's patents. Yamaha is still pursuing it's own 4-wheel leaning models. Piaggio introduced it's own leaning three wheel model but the 4MC has a much lower CG and a much better suspension setup. The extra grip and stability is even superior than a conventional car because of dynamic CG control when it leans. The 4MC's CG always equally distribute maximum grip at all corners in all driving situations. Road camber & bumps are even handled so much better than typical car suspensions.
