+1zoommx said:Those typically run in two different classes, but not always. Either should be equally competitive within their respective class. If you're racing any age group classes in addition to "era" classes the 79 would likely be a better choice.
Enduro_Nut said:I would buy it based off the classes... in AHRMA they race 2 seperate classes... Historic(75-77) and the other class(can't remember the name!) 78-83/84(?)... I would not want to race a 79 against an 83/84... ALOT of difference(water cooled alone is a big change)...
I race Historic mx and cross country on a 77...
