can i put a bias-ply tire on a sport bike looking for tire for my bike

Can you? As long as the size is correct for your rim, sure you can. Will it work properly(what you really mean, I think)..... well, that depends. What year and model bike are we talking about, anyways? That might be a factor. But as a general rule (and there are some exceptions to this), you don't want to mix radial and bias-ply on the same bike.

If your changing both tires at the same time, and can find 2 correct size tires that will fit your rims (bead design can mean that some tires won't seat properly on the wrong type rim) you might be able to run bias-ply on your bike. But radials are generally a better performing tire, especially if the bike was designed for them in the first place.

assuming you have got your self an old retro sporty, I cant see why not

but

If ya thinking about fitting cross plys to a late model sporty, then, WHY WOULD YA ????? they handle like dodo, but look kool

Front or back tire? What bike, what tires on it now? If you are referring to a late model sportbike, I doubt if you can even find a bias tire to fit the 180/190 rear. Older sportbikes actually came with bias tires.

Generally a radial front with a bias rear is a big no, actually illegal in UK and other places. A bias front with a radial rear can be OK and is the current recommended fitment for the new Bonnies by Metzeler.

My current favorite tires are a bias Lasertec front with a radial Road Attacx rear.

its the radial tire on a crotch rocket that makes the bike handle better than any other bike! I wish someone made radial tires for my size, I would be the first one to buy them. Could somebody find me a set of radials in rear size 170-80-15, front 130-90-16?

did you get laid off from the factory? You sure have been in a posting frenzy lately.

I don't work in a factory, I have a top level, important state goverment job in public relations where I can get what I want with my good looks and charm. I meet with and talk with very important bussiness owners everyday, I meet high class bussiness women that are soo beautiful you guys would melt being anywhere near them, I help them in making a connection between their bussiness and goverment. Thats how I know how a motorcycle business is run and managed.

Ahah...haha....you are quite the modest one.

Edit: Actually, let me make this post worthwhile - what's the difference between radial, biased, non-biased, square, sinewave, triangular...I'm completely lost. I know it has to do with the way the inner layers are run, kind of, but what's the real difference? Is there a difference in handling, or weight, or tolerances? Educate me on this...I'd like to know.

That site does a good job of going over the differences. It's also concise and has good diagrams.

I'd venture to say that it's much more important for cars, but the construction will make a difference in cornering where larger loads are being applied to the tire.

Actually I'm reasonably certain handling has something to do with the following:
Rake
Trail
Swingarm length
Wheelbase
Height
Clearance vertical and leaned over
Tire compound (sticky tires stick better du'h)
Wheel diameter
Wheel width

Of course I could be wrong.

Radial tires from what I understand handle high speeds better then a bias tire or bias-ply.
