Neither...
AFTER taking the MSF course
I'd do one of the two:
a: Get a Ninja 650 or SV650, and practice right wrist discipline. At low RPM, the 650s aren't that much more than the EX500, but is a much better overall package. I WISH I started on an SV650 instead of an EX500, i'd still have the SV... THe Ninja 650 is especially good because it is very narrow, has a really low CG, and has a very low seat height.
b: Get an EX250/Ninja 250. Its fast enough for the freeway, very VERY light and forgiving. And when you upgrade to a bigger bike, you either sell it for almost what you paid or KEEP the 250 as a commuter hack/trackbike, as its light weight, tossability, and low cost make it a much MUCH better track bike than an EX500.
In retrospect, I wish I did one of the two options instead of getting the EX, which was a great bike but I replaced it in 2 years with a VFR.
