Couple of questions regarding performance of some pre 85 open class bikes:
CR480 vs CR500 - are they similar enough not to make a difference, except for the front disc
KX420 - is it hopelessly outclassed by all the other bikes in the class, just wondering as a good one is about half the price of a KX500!!
The KTM420 above is a great looking bike, does it have a smaller tank than standard on it as it just looks a "thinner" than others I have seen? How difficult are parts to find for these models as it would be a great alternative to a YZ or RM
