dont take a short cut on messing with your front end like that x. lighter wheels will make your bike more flickable too.

 

The only thing a lower profile tire will do is make your overall circumference smaller and make your speedometer off even more. It will not help cornering at all. Also you take away the tall sidewalls that help soak up bumps, so now you will feel the bumps a ton more in the front end.

 

Now that I think about it, how will dropping the tubes help at all? I mean the front dives inches when you brake going into a turn, an extra 5mm is nothing. Am I missing something?

 

x and 056, you guys are both missing something here.

 

So evil, your saying the only thing that could help is a lighter rim?

 

Xrider not to be mean or anything but maybe you should learn the bike a little more. After a little while on it you should be able to fick it into the corners with ease.

 

dropping the front will help the bike lean into the turn but only at high speed will you really notice the difference! the reason its not really popular is because it changes the "rake/geometry" of the bike making the bike shake and become unstable at high speeds and it decrease your ground clearance. the best thing to do is add a 3 or 5mm nut on the rear spring lifting the rear end. if you are talking track, than even a millimeter can make a difference. i looked into this and asked dave moss of catalyst reaction suspension tuning about getting the bike to lean better on turn 1 at thunder hill (120 mph turn) and his recommendation was drop the front 1mm at a time. as far a tire profiles, here is a fun fact: even if the tire sizes are the same, there is a difference in the outer diameter/profile of the tire between brands. michellen and dunlope have a larger o.d. rear and smaller front. perelli and metzler have a smaller profile rear and larger front. bridgestone is the intermediate between both. So by changing between these tires actually you actually change the geometry (rake) of your suspension. Going from the stock bridgestones to perelli I dropped the font of my bike 3 mm. lighter wheels will achieve what you are looking for due to the decrease in unsprung weight but they cost some $'s.

 

I do agree with the rims. If you would get the carbon fiber rims you would notice a drastic decrease in the gyro affect, but that comes with a $3500 price tag. Now that is top of the line and you can get cheaper rims that are lighter than stock, but all in all if you have the $$$ to burn do it, if not and you are just going to ride it on the street with the occansinal track day, then dont waste your money cause your never gonna use the bike to its full potential anyway.


I was looking into the carbon fiber rims, but just couldnt fork over the cash lol

 

simple.... get your suspension set up for you...

 

for the question in general. suspension isnt going to make the bike turn quicker. its going to affect the way the bike handles when its in a full lean, slow turn, pot hole etc..

like russ mentioned, less rotating mass, quicker flickability. heres the difference my bike made with aftermarket wheels on it. while riding, it takes minimal effort to throw it into a lean and a "s" turn is even more fun. i just put my wheels on today and by dropping the weifgt in front 6 pounds and an self estimated 5 to 7 pounds in the back (i didnt weigh the rear) it was like getting on a 250 and flinging it around.

if thats what your looking for then lighter wheels. but be looking to spend a good 1500.00 to 2500.00
