How much faster is the 675?

[Yak]

I know this is a really stupid and juvenile question, but Im just a little curious.

How much faster is a 675 compared to a Speed Four? Im not looking for numbers, but rather real world experience, seat of the pants dyno. When going from a Speed Four to 675, is it a "WOW this bike is so much faster" experience or more and a "yep its a little faster than my S4" experience?

well i took one for a spin and it blew my mind there is power everywhere and it pulls so hard in every gear, i wouldn't say its faster as such its more the the way the power is delivered!

An S4 has a little more torque than a TT600 and a little less top end. A 675 has something like 20% more torque and horsepower than either of them. You will definately notice that. I sure did.
