It was a hoped for fantasy.
It doubt a Honda V-2 sport bike will ever happen again.
At the very best, you might see a V-4 sportbike from Honda, but I doubt that as well, unless racing demands it.
While Honda loves the V-4 design (RC212V for instance), it is so much easier to package an I-4 for street use.
And sadly, most everyone agrees. Which is why (except for the current R1), they all sound monotonously the same.
It's too bad as I'd love an RC51 successor.
That's why I'm hoping Erik Buell Racing will find the financial wherewithal to begin full production of their 1190RS based bikes.
Their web site already has spots set aside for future models that I hope will reach production.
The current (very limited production) 1190RS is an incredible pieces of engineering.
The equal of anything out of Japan or Europe in terms of performance, quality, and technology. Proof of what Erik an Co. can do without H-D shackles.
If he can translate most of that engineering into an affordable package, I say go for it!
I used to have an '03 XB9R, and while the engine was a dog (H-D derived lump), the bike itself was a handling demon.
