I want to be really careful how I say this, since I bear no ill will at all to Brammo/Victory. But I think it's important to remember that just because something's cheap, that doesn't necessarily make it a bargain.
I'm the first one to admit I'm a Zero guy, I just prefer their design philosophy. I don't like carrying around a gearbox that I don't think adds much to the experience, that requires maintenance and someday repairs, when it's easy to design an electric drivetrain that gives plenty of torque at low speeds and adequate power at high speeds, without a gearbox. Same with water cooling...that's a lot of leaking/flushing/maintenance/weight that us Zero riders avoid completely.
But that's just my preference and design sensibilities. Brammo/Victory is a perfectly legitimate way to go, and I'm not going to try to tell people who prefer that route that they're wrong.
It does seem like there's another monkey wrench in the system now, with it being discontinued. The reason the price has dropped significantly is that people are worried, probably rightly so, about being able to get service or even just parts for the bike when/if it becomes necessary. What if the radiator develops a leak? Is it copper and easily repaired, or (more likely these days) aluminum and plastic and basically disposable? Maybe you can find another one five years from now, maybe not. Not that the bikes aren't worth having now, but the prices are dropping because the perceived value is dropping, based on that uncertainty.
Again, I'm not trying to preach to the unconverted. Just keep your eyes open and know what you're getting into. You have to make your own decisions on how you spend your hard-earned cash.
