A lot of people just can't seem to come to terms with the concept of a technology based class . The air cooled motor , drum brakes and no linkage rules for Evolution class seem pretty simple to me , but just needs clear guidelines on the eligible components that can be used . Doing away with Evolution class would leave a lot of currently raced bikes obsolete , such as YZ250/465 G & H Yamahas , '80 to '84 twin shock Huskys , Maico Mega 1 & 2s , Can Am MX6s , '80 & '81 KTMs and Honda '80 model CRs . Naming a class as pre '82 seems like a pretty dumb idea to me , seeing that none of the Japanese '81 model MXers would be eligible , except for for the Yamaha YZ250 and YZ465 .
But a pre '80 class also has some appeal to me and would bring more bikes out that are not often seen , such as Yamaha YZ E & F models , Maico Magnums , Suzuki RM C & N models , Can Am MX4 & 5s , '78 & '79 KTMs , KX Kawasaki A4 & A5s and '78 & '79 Huskys . If the Evolution class has moved to be run with post classic classes at the nationals , then maybe there is room for a 'pre '80 class at the classic nationals . I have a couple of '79 Maico MC440 Magnums and a '79 Husky CR390 , all in bits , that would be worth putting back together for a pre '80 class . But really , there can only be a limited number of classes to fit into a day's racing , without having the length of races being too short .
