    warped rotors

    My front rotors are warped, contacted Reno's Yamaha-Aprilia in Kansas City, they contacted Aprilia and Aprilia says "its a wear item and not covered by warranty". Anyone else have this experience?
    They warped at about 8000 miles. That seems like short life for a set of rotors.
    What the hell good is the warranty.

    Similar problem with my Caponords front rotors. They were found to be warped at the 9500 mile service when the bike was only 13 months old. warranty replacement was rejected on the grounds of excessive mileage - let's face it; they're both sold as tourers.

    I chased Aprilia UKs Customer Services Manager and he sorted out replacements for me. Seems to be that Aprilia reject every warranty involving warped rotors as a matter of course and site 'track use' as a reason.

    By the way, I'm still waiting for them to be fitted - diagnosed in September.

    Angry Warped Rotors

    I have the same problem on my Futura (2002,bought 2nd hand, last May). It is quite slight and not noticable at legal speeds, but when I brake from higher speeds, the bike shudders until it gets down to 120 km/h (75 mph) or so. I really hate it but the bike was out of warranty when I bought it, and even if it were under warranty, I doubt the circus that passes for a distributor here would honor it. Is there an aftermarket replacement anyone can recommend?

    I somewhat agree with Aprilia's stance on this. If you have some hot rotors and splash through a puddle of water, your rotors will warp. My Ford Taurus SHO eats rotors, and they are much more substantial than the Futura's. I have had to have the rotors skimmed with less than 1000 miles on them. And I buy the "good" Bendix rotors, not the cheapo. Your individual driving or riding style has some influence on this. I don't need a pedal or twist grip. Just a switch that says IDLE and GO.

    Rotor shudder has come up before, so do a search.

    At any rate, be sure it is the rotor and not just the mounting buttons being 'hung up'. I had that happen once and a careful cleaning cured it.

    AF1 used to offer rotors for sale for the Fut, but they are not listed any longer. ??

    Make sure that what you are feeling is really a warped rotor. Several guys have found that the floating buttons/rivets get corroded & will bind causing a warped rotor feel. Spinning the buttons so that they are free to move has worked in some cases.

    As to replacement rotors there are several options available. Email me for more info.

    Mine warped at (around) 4500 miles, at just over 1 year old, so I claimed under the warranty.

    The first answer was "They're a wear item".

    To which I asked "what, in 4000 miles ?, and they're not worn out, just warped"

    They did the work under warranty.

    Stick on at 'em, I don't know how the law stands in the US, but in the UK I was going to start shouting about "not fit for purpose" if they hadn't come to my way of thinking.

    I've had my Falco rotors replaced twice under warranty. No problem.
    The rest is 'what John said'.

    I have had a judder 2 or 3 times now.
    the Rotors ( otherwise known as brake disks) get a good service which cured it every time.

    Off with the disks and clean the "buttons" that link the disk to the carrier. These are meant to spin free, make sure they do.

    Hot soapy water, and I use washing powder as it lifts the oil and grease so well, and scrub the disks with a stiff brush. then use wet and dry abrasive paper (the kind for preparing paintwork) and rub round the disk again using the hot soapy water on the wet and dry.

    Then using a drill bit, by hand-not in a drill, just smaller than the cleaning holes in the disk I slide the drill back and forward through the holes to clean the crap out. An old chuck is ideal for a handle on the drill bit.
    then, a last scrub down with the soapy water.......... and what you have is?


    A pail of very oily muddy water

    worked every time and takes about 2 - 3 hours.

    Rab

    OH!! and don't forget, the pads are covered in it too

    Get the pads on a very coarse bit of sand paper laid on a workbench and resurface the pads ............

    I find replacing them under warranty is a lot less effort!

    Thanks for the tip. I'll try that when the weather warm up to where I feel like working on it. In the mean time I'll e-mail Aprilia and see if I can get any results from them.

    If Aprilia can't figure this out for themselves I don't see why I should make their life any easier.

    Of course, once the bike's out of warranty, that's a different matter...
