I bought a set of the PM wheels from St. Paul HD recently. I appears that every thing except the rear rotor will bolt onto the new wheels just fine. The stock alloys have holes drilled and tapped for the rotor to fasten. The new PM's have a smaller "rotor" that the brake rotor attaches to. That said, Is there a nut/bolt kit that I will need to attach rotor to wheel. I asked at my local dealer yesterday and got nothing. There was no illustration given for the PM wheel option in HD net. Any info would be appreciated. Thanks, Matt |

Sounds like you need these: http://www.americansportbike.com/shoponline/ccp0-p rodshow/17029.html Just looked at my PM's compared to the castalloys.. looks like you'll need nuts as well for the back of those bolts. You might talk to Al and see if he offers the nuts as well for that rotor bolt kit. (Message edited by pkforbes87 on April 29, 2009) |

He also needs the rotor adapter which is not listed in the parts books. For some reason the 10 mm. lock nut for the rotor to adapter bolts are not illustrated but listed. |

"The new PM's have a smaller "rotor" that the brake rotor attaches to." I assumed that this smaller "rotor" was the necessary adapter. |

Yep, its about 5 1/2" in diameter and 1/4" thick. |

on a side note J- when looking through my 02 X1 parts book I noticed that the nuke blue wheels are listed as castalloy, the silver, and white wheels are both listed as "wire cut" or something like that (don't have the book with me atm) Any idea what the difference in wheel construction is? Or is it just a parts book abnormality. |

I noticed when I installed mine but thought that I just needed to get some washers and nuts. Everything lined up when I put the rear rotor on and is working fine. Do I need to get this adapter too? |

The pic and link mentioned above looks like a replacement for what I have, (works on cast and marchesini) If a washer and nut is all I need, then cool. I figured there is a parts kit.... not just going to parts store for washer/nuts. |

the adapter part that I think you're referring to is almost definitely there. From looking at the PM rear I have, there wouldn't be any way of mounting a rotor to the wheel without it. I'm not home ATM so can't look at the wheel, but IIRC the adapter piece mounts to the hub using 5 bolts, and the rotor itself then mounts to the adapter with the 4 bolts pictured above, plus nuts on the back. |

My PM wheel looks like they machined the adapter plate into the wheel. There is just 4 holes for the rotor bolts. I did have to notch the washers to fit or else they would hit the hub. Well so far I have about 300 miles on the wheels with just the washers and nylock nuts and no problems so far. I'll be calling Al tomorrow for some parts and I'll ask him about this. |

Some of our PM wheels may be designed a bit differently too. You could also try contacting Performance Machine directly and see if any parts you may be missing are available from them. |

Ok, I talked with Al today. He wasn't to familiar with the PM wheels. The rear caliper is a floating one and if it will fit onto the rotor and wheel without any binding it should be fine. I am going to leave mine "as is" since it has worked fine for 300+ miles. I couldn't get thru to PM but sent them an email and will post what ever their response is if I get one back. |

If you have the PM rear rim (mine is a later one that did not come with the bike) it has a 5 bolt aluminum adapter to the rim to accept the 4 bolt rear brake rotor. This is a later style so maybe the earlier ones were machined to take the rotor. Does anyone have a true stock Tuber that came stock with the PM rims that can clarify this. With out the spacer my bike would not accept the stock rotor at all. (5 bolts to 4 go figure) |

Here's a pic of both. Is there a standard descriptor that notes the difference between the PMs with a slot and those without the slot. I'm guessing that's what's going on, here. While we're talking about differences, notice that the castalloy is rough with a shiny surface. I thought they were all smooth. Is there a certain model these went with?

OK!! This is what I have. Top pic is what is on bike now. The rotor bolts thread into the wheel. Bottom pic is what I have to work with. The rotor bolts have nothing to thread into. This looks like easy_rider's set-up on his PM's (pictured above) Easy_rider, How does your rotor fasten to the wheel?? |

Ok I got an email back from PM. The adapter ring comes installed on their wheels from the factory. Matt's picture clearly shows the adapter already installed with the five bolts. All you need to install the rotor is to get some nuts for the 4 bolts. |

I had hopes of popping the rotor off and showing a pic like Matt's, other than his newer PM has six holes for the adapter mount as opposed to my 5 hole mount. The problem is that my PM has a checkered past. When I got it four of the five pulley bolts are broken off on the other side. Apparently the rotor side will be just as difficult to disassemble. Suffice to say, there is an adapter plate that has 5 bolts going into the wheel, with 4 holes for a bolt and nut for attaching the rotor. Both rotors measure the same diameter, at least with a tape measure. Also, FWIW, the PM on my '99 has the style of rotor pictured above on the castalloy. All in all, it seems like it's all about the adapter plate. |

Roger, Your adapter mount attaches with 6 bolts, as does mine. Why does your wheel say marchesini? Just a sticker? |

Huh. Guess I gotta work on my addition! Good eye. It's a sticker. I gotta laugh when I see it - like earlier tonight. I asked the previous owner of my S2 to include the PMs in the deal. He may have got the better end of that deal! |

You just need nuts for the bolts. No need to remove the adapter. If the mounting bolts aren't long enough just get some that are. Polish them up before you put that rotor on. It will be much easier. Good luck and let me know if you have any specific questions about the wheels. I have ones like the top picture on my 97 s1. |

Guys, there are nuts on the back of the rotor bolts on the PM wheels. No part number is in the manuals though, that's the problem. |

So, if I get some grade 8 stainless nuts and maybe washers I should be in good shape, right? I'm thinking the existing bolts are going to be long enough. |

IIRC they are lock nuts. |

Matt - I used nylock nuts and some washers. I had to notch the washers because they would hit the wheel hub. I still torqued them to the factory spec for PM wheels. |

yes lock nuts |

Yea I bought some stainless nylocks at Ace and used neverseize. And also used stainless bolts too. |

nuts that lock...that would be uncomfortable. |

Yes, Wilson, nuts that lock would be uncomfortable! ! Thanks guys for all the input. I really appreciate it. I thought locknuts would work fine, but when I couldn't find any info to back it up, I was a little concerned and didn't want to do anything stupid. (cuz i never have) Well, allright, I'm stoked!! I just have to use up the rest of these Diablo Strada's and it will be time for new wheels and tires. I'll be traveling to east Tennessee in two weeks. The trip there and back, with a few dozen passes on the Dragon should just about use them up. I'll be going to the Diablo Rosso's for my next tire. Has anyone of you guys tried these? Good, bad, bout the same?? Thanks again for the help. Matt |

I'm anxious to see what kind of mileage you get from the Stradas. You putting a 170 or 180 on the rear? |
Mdoughten
| Posted on Saturday, May 02, 2009 - 02:52 pm: |

I've always ran a 170. (factory spec) The Strada is what is coming off soon. I'll be putting Rosso's on this time. I have been using Strada's for a while now. I'm looking, trying to find the mileage got out of the last tire. I will find it and post soon. |

I am getting ready to buy the PM wheels on ebay and I cannot tell if they have the adapter plate on them. I have another set of pms with the adapter plate. Is there a source for the adapter plate? Has anyone bought and received the ones on ebay from the dealership that can comment on them? |
