Here is what I meant for FUSION!
Take a look at this wild lady!
This is her dream for yrs! But she has been having that damn backpain, and hardly, barely can hold on to the bike. The bike will eventually finish the rest of the ride w/o her. This is what is going to happen w/ that 512M, the upper Japanese part can hardly, barely withstand the windload & let the lower part enjoy the rest of the ride!
