Hey Stridey,

No alternative that i'm aware of.

I would strongly recommend that you put your foot down (politley) with your dealer and insist that the rubbers are replaced under warranty. As far as i know replacement of the rubbers is not mentioned anywhere in the service shedule or handbook, so they shouldn't be classed as a 'wear&tear' part. I recenty had my rubbers replaced under warranty along with the sprocket bearing (and starter motor, different story tho) and the dealer didn't quibble at all. If your dealer wont budge, maybe try a different one?
