MZ/MuZ Riders

Hello everybody,

I just bought a 1996 tour and i just noticed that the rear tyre (a Bridgestone BT45 130/80) has like about 4 cracks (some are 4 inches long , some 1 inch) almost looking like cuts with a sharp knive just about 5 mm away of the wheel rim.
I posted some pictures.

Do you think it is safe to ride the bike ? If you think not , would it be best to put another BT45 in the rear ( the front tyre is a BT45F 110/70 and is in very good condition with very low mileage !)

I can get a Pirelli Diablo 150/60 for 100€ , and a BT45 14/70 for about 140€. Any suggestions on this choice ?

Would it be wise to mix a radial tyre (Diablo) with a diagonal tyre (BT45) ?

Any other suggestions ? ((I would like to keep the BT45 front tyre because it is still almost new)

Greetings from Belguim !!!

Get rid of the rear now! those appear to be dry rot cracks due to age..can cause a blow out..Go with the BT45 to match the front.
I have Conti Road Attacks on my sport..so far they are terrific...

These are NOT old tyres , they have a DOT code of 2007 , so the tyres are only 3 years old, so no dry rot due to age.
Dry rot has a lot of small cracks !!

And by the way the Conti Road attacks do not exist in the size you need for a Skorpion Sport , maybe you have Conti Sport Attacks ??

Ah yes,Sport Attacks!!

Hello,

I have fitted a Pirelli Diablo 150/60*17 tyre on the rear. I hope it will not square off too quickly.

I have to say I am very dissappointed on the fact that there is only ONE person who has posted a reply and that this reply was completely besides the point in this case (dry rot ?????? )

I just don't understand why a simple topic like this one didn't have more reply's ?
Maybe this forum is as dead as the MZ company is , just take a look at their official website, seems like a dead company to me ...

Greetings anyway.

You will eventually find this forum a wealth of info for your bike....I was looking at your pics, and in retrospect,the long cracks may have been caused
by a tire iron,having said that, examine the smaller cracks by the wheel rim..this is what I was looking at..also what week in 2007 is the date code,as
over here in the US some tires of three years may be considered a bit aged..just my thoughts.
Yes, the MZ factory is about dead(according to rumor).They have put a Moto2 bike together for the Motogp series this year though...

Good luck to ya and let us know how the combination works for ya.

To me it looks like the tire may have been exposed to some kind of petrochemical grease or product during fitting... at any rate a tire with cracks should be replaced, regardless of the cause. Just my 2 cents.
