What exactly is a v-twin motor compared to other motors that are in such a bike as honda cbr etc? What are the pros---cons?
Thanks in advance.

 

i know that most of them cant rev as high, but your going to gain alot from the tq, your just not going to have the high hp...

 

harder to get higher rpm's so usually less high end torque, but it'll be getting all its power early on, not like at 13k rpm

 

Pro
comparatively linear power delivery
compact exterior dimensions

Cons
lower maximum power output
rougher/higher idle
lower fuel economy

Basically, vtwins are "friendly" in delivering power which some take as nice for a streetbike but many vtwins are quite rough which detracts from "streetability".

 

PRO:

BAD *** SOUND!

 

thats for sure! they do sound bad ***, but thinking about it, would almost be better for riding in and out of traffic to have that low end power, alot easier to get outta the way and make passes, dont have to keep it so high revved..... still cant beat revving to 12k tho hehe

A-F*CKING-MEN

A guy I ride with sometimes has a piped rc51. Sex on wheels i tell you.

 

Torque
Power (power in every gear/engine speed)
Sound
The dumb look on harley owners when you blast by em
Uniqueness

Disadvantages will be that if you're power hungry, you're going to get more power out of today's 4cyl liter bikes, you just won't have to rev to 15k to get there.

Went from a R6 to a TLR - the r6 feels like a scooter now

What twin were you looking at? RC51? TLR? Duc?

I have to disagree....unless your talking about harley's. I personally think that RC51, TLR and ducks don't sound anywhere near as good as a inline for with a pipe Thats just me though, however my dads harley sounds badass and its almost 30 years old....its more mid-evil than anything but i don't like the sound of the new v-twins (shrugs)

 

everyone has their opinion. i heard a RC51 with pipes and it did sound BAD_ASS_ but hardleys with pipes sounds like **** to me, but i am looking at it from an engineering perspective. modern Vtwins that have a 90degree cylinder offset have a symmetric exhaust note. a nice uniform rumble.

all harleys have the potato potato potato sound from the cylinders firing close to the same time instead of equally spaced. it sounds like the thing is going to die at any second, and the engine must have a heavier flywheel than a balanced engine to keep the reciprocating mass moving and compressing the next cycle.

the vrod has a 60degree cylinder angle, but the crank pins are offset such that the cylinders fire 180 degrees out of phase just like the jap/ducati bikes so it sounds more uniform. i think rotax engines are the same way (aprilia?)

so thats why i like the smooth rumble of a modern, balanced engine, cause its the sound of a good design thats not going to vibrate apart. the new twin cam 88B harley engines are also nicely counterbalanced and are as smooth as glass and keep that taco bell neverending fart sound that gets all the harley people wet in the crotch.

My dads harley does die at any given second unless your constatly slightly playing with the throttle to keep the revs up.

 

yep every one i have been around or ridden has been like that. if you keep it bone stock it is better behaved and the fuel injection supposedly makes it run great, again as long as its stock.

 

"Cons

lower economy? Harleys get 50-57mpg depending on the model


I ride a v-twin. and no, you dont get em for the power, but because they have the majority of their power down low, they are much better suited for the streets as opposed to the track, like an i-4.

I dont get why stunners get such a thrill out of blowing by a guy on a harley. Is it challenging? do you prove something to yourslef or anyone else by speeding by a motorcycle with an engine designed for "cruising" ??

just my .02

sohc

 

no i think its silly to blow by a guy on a harley just to show your bike is faster than his, thats not the purpose at all, cause those things are made for an entirely differnt reason and the guys who buy them don't buy them to do 0-60 in 3.4.

I respect all motorcycles and the guys who ride them, scooters on the other hand....hah

I've found this to be somewhat true on my TLR. It does not like to go slow (under 3k or so). It can be a pain to cruise around on campus where the speed limit is 20mph....

 

ya i was wondering how the tl1000 did.. i have been thinkin about gettin that bike for awhile now but iam just not sure about it yet. but the sound is awesome on a vtwin and i think you get them for more of a riding enjoyment not to go blazing fast.

 

well i have a 996 superhawk v-twin and if 140 miles an hour tacking 7500 rpm redlineing at 9500 and still haveing 5th and 6th gear id say theres plenty of power and you have torque just about where ever throughout you rpm range where as straight 4's only have it roughly above 5k to 6k, personally i love the torque and my bike is god awful fast, well fast enough for me sure the r1's faster but are you gonna ride it 165 mph so will you know the difference, i wish the rc51 wasnt so dam small or eles that would be my next bike

 

TORQUE!!!!!
