your concerns are justified. you will notice significant difference in handling, if you've ever ridden with a severely under inflated tire (say a normal 160 or 180) riding with a 240 would be about 3 times as bad. kinda like you're ridding on sludge (if you're used to good handling, and can tell the difference)

Will ruin its handling as you know it. Wont lean as much or as quick. the added width n weight will also take away from the top speed n acceleration.

Less power, loss of turning capability and looks like sh$t.

I am going to have to say it dosent decrease the cornering that much. If you extend your swingarm 2 inches and get the new Pirellei 240 z rated tire on it and lower the bike 1 inch it is proven by Pirellel that you might lose as litlle as 2-4 % cornering thats it. If your not scraping knees everyday dont worry about it.

Not to offend anyone but I call on the above. Yes if you're not a knee dragger, if you dont like twisties, and if you just cruise town and commute on you bike sure you prolly wont notice to loss much. But if a 240 tire didnt affect the handling wouldnt you think the manufacturers would up the tire size??? But if you dont use your sportbike anything like it was designed to do then go for it.

fatter tires give better grip powering pass the apex. look at the GP rear tires.
for a literbike, it will be safer. but the only question is, will there be enough clearance to prevent rubbing.

i've ridden superbikes with oversized tires. i am able to hammer out of corners without high-siding.

bigger tire = larger contact patch = more rotating mass = readjusting suspension to compensate for new geometry.

the rear end needs to be raised to change geometry. fatter tires will slow the bikes turn in characteristics. either raising the rear or lowering the front will compensate.

extending the swingarm back just changes the whole purpose of the bike.

im not gonna say it doesnt affect handling at all-just not as much as everyone claims. i would think more like 10-15% loss based on what he just said. a zx12 is 57.1 inch wheelbase, stretch a gsxr 2 inches from 55.3 stock, to 57.3, add 40mm of sticky tire (that new pirelli is a real gd tire, not like the chopper crap they used to use) and since we all know u can drag knee on a zx12 or busa (busa is 58.5inch wheelbase, but comes with a 190tire) it wont kill the handling. you can still have fun in the twisties. its not like you have to lower it, rake it, etc etc when you add a wider tire. its the combo of slammin a bike, raking the front end, stretching it 14inches, and tossin the biggest (360? 400?)back tire you can find that makes it not want to turn.

Thanks DNYCE. Look at the M109R from Suzuki. The bike is huge on power and corners like a gixxer but yet its a cruiser and comes with a 240 rear tire. We all have to admit, that it also depends on the rider.

if you go to a 240 on a sportbike, automatically means new rim and swingarm, and usually offset front sprocket too.

2inches back? c'mon

I have to say if you extend it tofar out it does become a eye sore. IMO, try to keep the tir totally underneath the tail section.

Why extend unless its gonna be dragged race? I see this more as a cosmetic mod than a performance one. To each their own tho.

I can't believe I just read that.

edit: I'm going to go buy a Porsche Carrera GT and put spinners and neon underbody lights on it. What do you guys think?

yea, looks are subjective, but in my opinion if you can draw a imaginary line from your tail to the ground, if your whole tire is behind that line you should be slapped.

If you whole tire isnt in FRONT of that line you should be slapped.
