Small flat crank V8's are just two regular I4 bike engines with 4 into 1 exhaust. Nothing sounds better than a flat crank V8. As iconic as the Mustang (crossplane V8) or any big bang V twin.
Little exhaust tuning and that's the sound you get.
Sadly, you can't really go over 3.5L with a flat V8 crank before they shake themselves apart.

Do you know what the 4 and 5 in 458 mean?

The F4 engine is a liquid cooled inline four cylinder four-stroke with two overhead camshafts (DOHC), 16 radial valves, electronic multipoint injection, induction discharge electronic ignition, with engine displacements of 749.5 cc (45.74 cu in), 998 cc (60.9 cu in), and 1,078 cc (65.8 cu in). The engine was derived from the 1990–1992 Ferrari Formula One engine. Early in the design process Ferrari engineers assisted in the development of the engine. MV (Cagiva at the time) quickly deviated from the Ferrari design, but they kept one important feature, the radial valves. The F4 engine is unique in the sense that it is the only radial valved motorcycle engine currently in production.The F4 is also one of the few production superbikes to have hemispherical chamber 4 valves per cylinder engine.
the radial valve is what give the F4 the ferrari sound, MV still used that engine on the current f4
nothing sound better than an MV @ 12000 rpm

Do you know if the F3 800 has the same setup? This sure looks nice:

Yeah, it means it's a grenade. The racing 458 ain't so hot in the reliability department.
4.5L's is really pushing it for a flat crank V8. Might have been better off with a 10 or 12. Or a V6 turbo with ERS. I'll bet on seeing some of those in our future.

Quite the opposite of a shaker, if you read the patent. It's essentially describing a way to eliminate vibration from a narrow angle V without needing additional, driven balance shafts like all such engines currently need. Since the difficulty of packaging a 90-degree Vee has long been a subject of discussion where motorcycles are concerned, the relevance becomes apparent. That patent app is all about vibration elimination of V-config engines, and doesn't specifically mention twins only. V-4's would apply as well, so I'd expect something using this tech from Ducati or Aprilia in the near future, likely in MotoGP first.
