As Jarvis stated, by lowering the front (i.e. pushing the forks up through the triple tree), the rake (angle derived from the relationship between the front wheel and the frame/body) is decreased. If done IN MODERATION this should aid in achieving quicker turn-in. Mine is lowered a couple of mm in the front, and I've ridden an RC with stock settings, and I could actually tell the difference (albeit minor) just putting around town. Most RC owners (to quell the disadvantage of riding an overweight piglet), will lower it a couple mm in the front, and shim the rear up a couple mm for quick turn-in. CAVEAT: Don't get carried away with decreasing rake, as you're flirting with instability, and the steering could get a lil squirly and toss out some headshake (I assume that your CBR has that Honda Electronic Steering Damper). Hope this helps.
