Take your own advice man

Bias and radial tires have significantly different dynamic properties. They deflect differently, create different cornering forces, have different damping characteristics, as well as other differences. In order for radial tires to be introduced into the two-wheel market, it was necessary to change certain characteristics of the motorcycle. The introduction of the radial tire led to such things as modified frames, new steering geometries and suspensions. Therefore, it is recommended that a motorcycle be used with the type of tire construction that it came with originally. If a change is to be made, then it should only be done if the motorcycle or tire manufacturer has approved the change. Above all, do not mix bias ply and radial tires on the same motorcycle unless it is with the approval of the motorcycle or tire manufacturer.

 

Thanks for the info Michigan 313
I just ordered a set of Pirelli Sport Demons 110/70/17 and 150/7017 they are bias ply and only cost me $200 installed. I keep you posted on their proformance after a few miles

 

I like the feel of these tires Pirelli Sport Demon
110/70/17
150/70/17

I would highly recommend these

 

i just put a pair of sport demons on my cane too, have not ridden since then, hopefully this week i get to take the ol girl out. i stuck with the stock 130, but had to drop to the 70 profile as well.

 

Well I am going to look at some tires for my bike tomorrow. I just looked and low and behold ... no wonder my bike is squirly. I just thought it was the cupped bald tire on the front and the back tire has a flat worn down the center.

Look at what the knot head before me had on it.

Front
Michelin Radial
Macadam 90X
120/70ZR/17

Rear
Michelin Radial
Macadam 90X
150/70ZR/17

Now whos the idiot ... Him for having these tires on it or me doing 120 on it the 3rd day I had it?

Well it looks like ME! [sm=smiley11.gif]

Micro, are you freaking kidding me?!?!?! 150 ON THE FRONT!?

Finally got to test out my Sport Demons, they are AWESOME! Very responsive and they dive right into the corners. I put 150 miles on them this weekend. I would also highly recommend them.

 

HAHA ...

No I ment 120 front and 150 in the rear. My bad!

I put on some Dunlop GT501's on Saturday.

Front 110-80-17
Rear 140-80-17

I put 350 miles on them this weekend. "Desert to the Moutains". I had a GREAT ride I was fat out in the Mojave Desert and I was twistin it like mad in the moutains in Big Bear! GOOD TIRES

put me on the list of dumb previous owners
mine came with a 160 on the rear, that combined with blown out forks makes it very hard to get the thing to cut into a corner.
this bike also has a "custom" tail, and is missing the rear fender and tire hugger. if i put a new hugger on before i put a new tire on, will the hugger even fit?

just a note on the "middle" number on tire sidewalls, its representing the sidewall height as a percentage of the tread width, so a 110/70/17 wont have the same sidewall height as a 150/70/17, but it will keep the proportions closer to correct if you match the middle number if thats the way it was from teh factory. This is also the reason the middle number decreases as the width of the tire increases, other wise your over all diameter would be much larger.

 

Hi, I am the new owner of a 90 600F. I found a service manual that says that the bike came from the dealer with 120/60/17 in the front and 160/60/17 in the rear. Is this justwrong, or is it just that everyone prefers the smaller size tires for various reasons?

Thanks,

 

If you downloaded that manual, it is not even for the F1...and yes those dimensions are wrong becuase it is not the right manual for the bike.
