FOUR POUNDS of additional crankshaft weight on the '12 bike?

Dang. 

That may make it easier to get off the corners, but it can't do anything good for the bike's ability to change directions quickly.

I hope heavier crank will calm the vibrations down a tad

Where did you find that info out?   That's a lot of additional weight  :bah:


The vibrations happen mainly in the bars at and around 5k RPM, but can felt in the pegs also on some bikes.  It seems that some bikes are more affected by vibrations than others. My '11 S1Krr vibrates very little, not much different than any GSXR I have ridden, but other owners complain a lot about it.
