what makes a v twin so much different to a jap bike in line 4 & how much difference does it make to performance.
 
Vtwin engines are only 2 cylinders sits in a V ...like your muscle cars
they are known for having power all through the RPM and every single gears which makes them way better in carrying speed through the corner...and it sounds extremely sexy when it roars

inline 4 engines are 4 cylinders ...like your honda civics
they're known for higher horsepower but on the track much more skills is needed b/c the power kicks in in high RPM (kind of like how Vtec works in a honda) it's definitely faster on a straight way and downhill situations but cornering takes more finess to down-shift and smooth throttling control...sounds like your import tuners

I don't know what Tim is talking about but no 600cc/750cc can keep up with a Vtwin 1000cc plain and simple...(if both riders are experienced) the people racing 750cc in the 1000cc races usually are way in the back 20+ positions from the front leaders (Honda, Ducati)
too bad Honda replaced the RC51 with the new and improved bad ass inline 4 CBR1000RR ... RC still the greatest in my opinion
 
Tim D hit the nail on the head. This is a touchy subject. Italian guys will swear there is nothing better then their Guzzies and Ducatis. Rice burners (myself included) will swear nothing beats a good Jap bike.
In my personal experence the V twins sound a lot better but the inline 4's have that high end kick at about 8,000 rpm that blows you away when it hits.
My CBR600rr (bone stock) eats my buddies Duc Monster (with almost twice the displacement and full exhaust) at every stoplight. As long as I keep the revs high he cant pull ahead. But its a Monster. Pulling up next to a 986 would be a completely different story.
 
Simply put, V-Twins are predictable, modern inline's are two faced. (due to low stroke, high compression).

The V-Twin typically has the low RPM torque and a predictable power band, trailing off sooner than an inline. They have a very low, thunderous bark that sounds like a freight train coming up a twisty rural road. They sound so low, unchallenged and beastly when one flys by your house at 80 it's very unexpected because it's a very misleading sound.

The inline is two faced, and has a power curve similar, but not as blatant or violent, to a two-stroke MX bike. They are very doggy until thye rise to a predetermined RPM when secondary fuel injectors come in, air box volume increased electronically, etc. and they howl to high RPMS like 14,15, and 16,000 RPM. MotoGP bikes are V4's, and they rev even higher. Especially the Kawasaki ZX6RR Screamer. The sound of an inline scream's resonating against a deep forest's trees is also very frightening to innocent bystanders. In my opinion depending on the bike, it sounds like a swarm of p**sed of yellowjackets fyling by.

You want to hear a good sounding bike, YouTube A Triumph Daytona 675 with a Jarine RTOne Pipe(Inline 3 cyl), TL1000R or RC51 (Vtwin) or any MotoGp bike. The New 2009 R1 has a crossplane crankshaft that makes it sound like a V-4 rather than I-4
 
in line 4's are a lot better balanced than the v twin...the twin also has a very distinctive sound when running.
