Besides the 750 twins, there's also a 450 singles class.

I'd love to see H-D put out a 4 cam single 450, and make it available in street form.
Why 4 cams for two valves train???

I think 4 cam just meant XR based single. If so, making that competitive would be tough. Maybe if it was water cooled, maybe not. A 4 valve water cooled set up is their best bet. Wait, that's half an XG. Go figure.

Brain fart - never mind

Oh wait - one mild set and one hot (spare set) would work

Forgot about the Blast - ugly as sin IMO, but that could be fixed.
