also, it does say a twin is designed for low end torque, but they are comparing it to a 4 cylinder....
"The V-Twin engine is designed to produce lots of torque a very low RPMs. While horsepower is good in the middle range. While this type of engine may not be as fast as an Inline-4, you will actually feel like you would get there faster. "

i dont really care what they say, i know that an engine with less cylinders but of the same size produces its power lower... the article even said that. i have ridden and researched a lot of machines to know. compare dynos from similar sized street bikes with variying number of cylinders and tell me what you see
These examples aren't really open for opinion or feelings- these are mechanical facts and are either one way or the other.
Facts are- 2 motors, same cc, same fuel delivery, same ignition, same application... the twin will give you more torque on the bottom end then will a single cylinder.
a 600cc 4 cylinder sport bike has nothing on the bottom compared to a thumper like an xr600

a 600cc 4 cylinder sport bike has nothing on the bottom compared to a thumper like an xr600
2008 GSXR 600 (599cc)
125hp @ 13,500 rpm / 67.7 Nm torque @ 11,500 rpm
1997 Honda XR600r (591cc)
45 hp @ 6500 rpm / 38 Nm torque (no rpm given)
It's a bad comparison- these machines couldn't be more different- except for the similar motor cc
I'm not arguing about it, it's all good here- but if we're going to discuss it- lets keep it relevant. Lets do some research- between two similar cc atvs single / twin and post the data. We'll all learn something.

you're the only person that ive seen that says a multi cylinder engine produces more low end then a single. EXAMPLE ONE: Fun Factor Preview, Fun Factor Preview - Budget Bike Comparo, Sport Rider article, Motorcycles article
why it looks like the twins are making more low end power then the 4s.....

as you can see your logic is wrong, you have it backwards...

as you can see here, the triple has more low end with the twin having more yet: http://www.motorcycle-usa.com/photog...ersport-HP.JPG
need more?

to twin cylinders yes. the daytona 675 is a triple, not a 4 cyl. from your article: "The V-Twin also has a few disadvantages as well such as: Low horsepower and top speed compared to 3+ multi-cylinder engines"
"
Single Cylinder Motorcycle Engines:
Description: Primarily used in smaller motorcycles where torque is more important that horsepower and top speed "

why can't I find any atv factory torque specs!
I can either find high rpm HP ratings or rear wheel torque-
No one lists torque engine specs for single / twin motors!
I'd like to see a torque comparison between:
2005 KQ 700fi VS. 05 BF 750i
2010 Grizz 700fi VS. 2010 BF 750i
2009 SP 700 VS. 2009 Grizz 700
single vs. twin, relevant application and similar in cc.
