I stand corrected. I've only ever seen a 500 in person so far, and don't even HAVE a VN750 in my possession yet, much less ever laid eyes on a VN1500L, so I'll beg your pardon in forgiving my confusion...
'Swhy I'm here, after all.
Well, hurry up and git one! LOL And, we're glad to have ya!
Most people don't know the differences; it takes quite a while, sometimes, to learn them. It did me. For instance, the 1500B is the same bike, appearance-wise but with round ears. There are a few other minor differences, not easily discernable. All three--1500A, B, and C(L)--have 4-speed trannies; the late '90s 1500D also had a 4-speed, but with a slightly different gear ratio, and it's supposedly interchangeable into the earlier A/B/C models.
I've never seen the 1500L in person, either; apparently they are few and far between. I do know of a few VROCers who have them.
I do have the 1500A, which begat the 1500B/C(L); they're all 3 called BUBFs--Butt Ugly But Fast. And I've got a set of fenders for the 1500B; they're almost exactly the same as the fenders for the EN500 and VN800.
Personally, I don't think they're ugly, but to each his own view, I reckon...
