I have to agree with you on that one Red, the Cx is a doddle to get on the main stand even though it is only 2 years younger than the KZ.
However the Cx was first introduced in 1978 and the Kz in 1979 !!! so in reallity from the age shouldn't make too much difference Having said that, the Cx was a completely new design whereas the Kz was basically an upgrade from previous 4 cylinder 750's.
The difference in weight between the 2 bikes is aslo much less than one would imagine.
I am sure the main problem with the KZ is the fact that the stand is bent.
