The KFX frame is very well built. It's not a material issue if any others are breaking. If Honda does it right, aluminum would be a good thing. I like EFI itself, the power delivery and throttle response. Also fine tuning is easier than swapping out a bunch of jets, but I'm NOT a fan of all the electronics that go with it. The thing I liked MOST about my Honda was it was so simple, easy to work on and reliable. More tech means more room for bugs. Now with the MXR, I'm starting to enjoy working on a bike again... IMO of course.
