so is that why banshee's and zilla's have about the same performance, except that the zilla has more low end and the shee has a bigger hit on top.

When is the best time to go for twins anyway? 250cc, 400cc, 500c, 600, or 750, or 1000? Or for how many CC should you start having twins/triples/v4's/v6's/v8's?

just wondering, there should be a formula for it somewhere

 

Awesome question and good discussion.

 

you just opened a whole new can of worms. that is hp vs. torque

first off i'm not familiar with zilla's but don't they have ten hp on a stock banshee

So here is my 2 cents on the subject

now this disscusion is more general, in that it applies to 2s and 4s

a 500cc single will make less hp but more torque than a twin of the same displacement

of course you can parallel fire them which is kind of a best of both worlds
