Why lower a bike.

Why would a person want to lower a bike. Other then the main reason of making it easier for a shorter person. A friend of mine lowered his 2004 gsx600r. The thing is, hes 6 foot. What are the advantages and disadvantaged of doing this???

I can see lowering the front end to possibly raising the rear end for better set-ups in handeling. Though have never done it.

Still I to have read of people 6', in my case 6'2" & 240lbs lowering the bike. Crumbs I only stand 5'10" when I can staighten up & weight around 175 lbs though more once I put on my riding gear. Also I am a bit short in the arse for my inseam trouser measurement is 29.5".

Well, if it's not for drag racing..it's for the Bling effect....Personally, I think lowering a sportbike is a waste..unless your short..

More like disadvantage, supposedly it keeps wheelies to a minimum and delivers power efficiently to the rear wheel if the swing arm is also stretched. But it seriously handicaps sportbike's handling to more like stretched choppers and HD.

Hammer gave the correct answer being "--Bling effect...".

How much of a handling hit does it give you. Does it make the bike harder to handle, or just not allow agressive handling. For example if you didn't ride the bike hard, would you notice that it doesn't handle, turn, as well as a non lowered bike??

Hard to say if you would notice or not. I know I would notice right away. You can do a simple test. Take one of you suspension components (doesnt matter which one) mark the settings, then turn all of them as far as they would go to either side. The effects of dropping the bike are going to be much more pronounced, so if you notice that, you will notice.
You are basically rubbing yourself of ground clearence to lean into, and you are lowering the center of gravity, so you will have to lean the bike more to corner (and you are already low on grounclearance to lean it into)

Hey Vash, let me just stray off the topic and nit pick a little, there seems to be a clash of opinions here. Your track day Buell buddy suggested that bikes with low center of gravity (his Buell for example, as well R6) allows to carry more speed into the corner, though I'm not sure about this, but wouldn't carrying more speed into corner mean the bike is far more nimble? Thus allow arrays of lines to choose from while going into the apex, so leaning most is not necessary than a bike with higher center of gravity. 600 CCs bikes have lower center of gravity compared to 1000 cc, though not as pronounced, but if we take Ninja 250, which is very low, it becomes apparent that bike is very easy to handle, even if it has ground clearance issues. I always figured things with lower center of gravity allows it to "hug" the surface as oppose to higher center of gravity, which is more stable but not as nimble, like cars VS SUV. Anyway, I could be way off, but what's your take on this?
