My front iso was in the same condition,
I wonder if its as much time related as milage.
looks good for sure! |

I was thinking the same thing: Maybe its time more than miles that is hard on these...
I did notice that the new one had different markings on it too. And it was really smooth and clean until I put the torque load on it and then the surface became crackled and what looked to be a protective coating sorta flaked off...

I had a similar experience, the lower half rubber is quite soft as well. Huglysses looked at this issue as he had some problems with his ( he now owns a uly )
I have put about 40 miles on my bike since finishing my repairs the vibes seem to be less. |

I think our isolators DO deteriorate due to milage (number of vibe cycles) and simple age -- just like a tire will dry rot over time, the rubber in the isos ages and changes, too . . . . . .
my first fron iso was toast after three years/35K miles -- but I live close to a major metro area, and I'm sure the air quality had something to do with it -- |

I thought I heard somewhere that these urathene replacements were not recommended for a Buell and that the stock units were the best you could do... |

Don't bother with them,I tried some of their isolators years ago hoping for a bit less vibes. Made it worse at cruising rpms.Might be because they are "tuned" to rpm range of big twins? Expensive experiment.I had better luck with my fabbed up heavy bar ends. |

thanks jim
but would they last longer??? would their normal state be better than a torn stock one???

According to Al at American Sport Bike:
Do not use polyurethane alternatives, they don’t hold up. The OEM part is the best you can do.
I don't know how he knows that, but I assume he'd just as soon sell you the poly alternative if it was better...
Anyway, I knew I'd read that somewhere. |

What FMJ and Nick Said!
it makes some sense the buell part seems to have a metal embed in it ( besides the sleeve ) |

Tat had told me that they sold several of them prior to me buying the biz. None of them lasted 1000 miles.
I don't have personal experience, I'm just relying on what the previous owner of American Sport Bike told me.

I tried to fab my own front motor mount for my 1955 Ford (the inline 6 uses three mounts) instead of buying an repro$$$ and found out the hard way that durometer ratings are very important when it comes to resonance of engine vibrations. The rubber I used looked right, but it created an incredible amount of vibration and thrumming at certain rpms.
Engineers (some, at least) have apparently been getting the answer right for a long time. |

Keep in mind the Harley Big Twins that use the same front isolators, the engine sits on the isolator where on a Buell the engine hangs from the isolator so maybe the poly might work better in that situation... |
