Not trying to question anybody, just trying to learn.
I had read that the K-bikes were 51.7 to the front, from the factory. Whereas the SRAD's are 50-50. How much of a difference would changing the weight bias front to rear make, if the geometry stayed the same?
Example, Put a 5lb. weight on the nose, as opposed to the tail.
Wouldn't changing the head angle, fork offset, make a larger impact on handling than weight bias? How does swing-arm angle affect handling? I am aware that Blarny gave me the swing-arm number to start with, but if I were to adjust it how does that affect handling?
Is there a book I can buy that is in depth to this subject? Chassis, and suspension design has always intrigued me.
Yes all of that. LOL!!! Does your bike handle ok now? There are tons of books all about geometry setup, suspension set up and different approaches to this and that.
The key is to stay as close to home as stock as possible. How picky should we get as amatuers, trackday riders, and club racers?
When it comes to the point where .7 percent of weight bias one way or the other makes that big of a difference for me I'll hopefully be paying a mechanic to make those nit picky adjustments.
If a bike is at 50/50 I'd say leave it. Weight bias starts changing more noticably when you start stripping the bike of unneeded street parts and replacing parts with ones that weigh less.
Too drastic of adjustments with where the forks are in the trees and rear shock ride height adjustments can really destroy the way a bike handles thats why I say stay close to home with geometry. The engineers who designed these modern late model sport bikes know what they're doing. And a 01 Gixxer is not old school. A 1972 CB750 AHRMA road racer is old school.
Don't forget adjusting where your rear axle is in the swingarm affects the geometry to. IE tightening and loosening your chain...
