V twins, let's say a 90 degree v twin for example, may have 270 degrees and then 450 degrees of crank rotation between power pulses whereas an evenly spaced four cylinder will have closer evenly spaced pulses (two pistons inhaling, 2 exhaling). The wider spacing of power pulses gives the twin's tire time to recover and grip between combustion events. Want proof? For awhile in the 2 stroke 500cc GP days, "big bang" motors that fired all their cylinders within 90 degrees of crank rotation proved easier to ride and far more tractable than evenly spaced "screamer" motors with evenly spaced firing order.

lets say your gong around a turn at low rpm say around 3-4k and you crack the throttle on a vtwin or a inline.

which bike is bound to let the tire loose first a v twin 800cc, a inine 600cc ?

wait a vtwin doesn't spin that high..The motors have different power curves and if you want to be fast you tend to operate teh bike in it's power range. Your example is like comparing a Mustang GT and a Honda S2000 at 4k. The rider needs to work on their body positioning, throttle input, suspension settings and tire pressures if they are spinning the rear that easily.

...it depends on what gear you're in. If you're in first, you're going 20mph and then I'd have to ask, "Why the fvck would you be taking a turn at 20mph, Grandma!?". I'm sure you're talking about taking a REAL turn and if you're at 3000RPM in 6th gear then you're not taking that corner very fast...maybe 50-60mph. If you wind the throttle to the bar from 3000RPM in sixth gear at 50mph which bike would break the tire loose? Neither. You're WAY out of the power band and in that gear it'd take a good 7-10 seconds before you got near enough power to lose traction. That's plenty of time to realize, "Oh...maybe I shouldn't have the throttle to the bar."

Fun question, though ; )

the whole point i broguth this up was because the guy who started this thread was looking at a vfr800 which is a big v style motor. hes a beginner And i was putting myself in the shoes of a beginner and thinking if a beginner wacks the throttle on a 800 v style motor compared to a 600 inline hel get mroe then he bargained for.

MonkeyLover

Lol...good times ; ) I'm kidding with you. The 800 twin would most likely spin the tire before the 600...yes.

but mostly because at that rpm a 600 far below its ideal powerband. When I attended California Superbike and rode their Zx-6's it was not hard to spin up the rear tire (and I am by no means an excellent rider). In comparison, my 851 is actually running 888cc pistons, 12.5:1 compression, very lumpy cams, open airbox, chip and exhaust. Compared to a stocker it has a less forgiving powerband and I'm running 2 teeth bigger rear sprocket. The only time I can break the rear tire loose is when there is no heat in it. Otherwise, the tire just bites and hoists the front end up. Twins are known for tractability. Once weight limits were made comparable in the late 90's it was the one thing that kept Ducati competitive in WSB since they couldn't compete with the fours in outright power.

remind me to shut the fvck up and not mention anything anymore ;p

thats all i was trying to say ;D

I'm just bustin your ballz, brudder : )
