Sorry but u really need to get your facts straight, if you're going to give people advice, make sure its RIGHT.
The change in vertical CoG results in handling response, it allows more time and more precision for riders in slow speed scenarios.
Example: those bicyclists that slow down before a light usually stand up (raising the CoG) why? so they can stay on the bike easier. Similar to motocross riders, their position on their bike is alot higher and they are constantly standing, not just because of clearance issues, but to aid in handling in rough terrain, etc. Try doing slow speed maneuvers like a figure 8 on your bike while your tucked behind ur windsheild (close to impossible); its alot easier to do slow speed stuff when your body is higher up. high CoG = more throwability
lower CoG = stability, high CoG = handling
A change in horizontal CoG will change weight distribution on the horizontal plane. Lowering ur bike will increase weight on the rear, which is not what you want when entering high speed corners
Further, lowering links will increase your trail
(in your case, a decrease in head tub angle), increase trail angle means less flickablity. does an american chopper (huge trail angle) handle like a sportbike? Uhh... thats a no brainer.
what you mean by better handling in corners is actually: better stability in corners
that isn't even the case because unless you lower the front forks to match the lowering link in the back, you bike is off balance already, you've got more weight in the back, and less turnability, which will ultimately be a shitty experience in a high speed corner.
bottom line, if you lower the back, you MUST lower the front to properly lower your CoG evenly. how do you lower the front? either by cutting the fork tubes, or by lowering the triple clamp (however you might have clearance issues with bottoming out your fender with your upper cowl)
and after you do it properly, remember you've now lowered your CoG vertically, meaning you will have less handling response in corners
and to add ontop of that, when you put in lowering links, your rear shock will be subject to more constant compression affecting spring rate (harder suspension) and also it will be subject to bottoming out easier.
AND your kickstand is not properly proportioned to your bike anymore because you've lowered it, the kickstand will make your bike sit more vertical now which will be subject to easier-to-tip-over-ility
so you'll have to cut your forks and cut your bike stand, just for lowering links, and suffer a less handling capable bike.
but hey if you just ride a bike in a straight line really fast and pussy out in the corners, then by all means go for it. but if you care about handling, corners, and track days like i obviously do, then its clear that i've stated my views on lowering bikes in this post.
so why do some suzukis come with stock links that can be lowered? so you're going to say, why else would they put it there?
suzuki also has adjustable stock rearsets, and the reason? think about sales. it would be easier to sell a bike that had options. bikes don't ever come with options.... thus they have lowering options to help sell their bike gixxers also come with the largest rear cowl storage, headlight flashers, motogp shift pattern all stock. why do you think the gixxer population is so large? R6s are touted as the best off production 600 track bikes, they sit higher up, higher than my cbr. obviously its not because they have a low CoG.....
but in all honesty i will admit that these changes from lowering your bike may only affect your bike to a certain degree, but why make something worse?
just a portion of the information i talked about covered here http://www.sportrider.com/tech/146_0...wer/index.html
