I think that what MMC have changed is the strength of the lower wishbone, this should not in itself change ride and handling. The loads going into the wishbone are of course related to what one drives over & how fast and how the spring/damper unit absorbs the shock......been there already.
MMC of course did not start from a clean sheet of paper with the three wheeler, they bought out Pete Larson of ACE in Seattle
http://cycle-car.com/ - maybe if they had started from scratch then ....but then on second thoughts... maybe not.
Good to see some 'old' friends here too, it's nice to put my oar in the water, trying not to cause more than very gentle ripples now and again. Regards PJB.
