I have searched through an extensive amount of threads but cannot find an answer. It might even be a stupid question but this is my first bike and first build so any help would be appreciated.

I have wide glide forks. I purchased a rear 9 spoke 16x3 rim that matches my rear rim to put on the front. I thought I could just swap the rotor and go but I noticed the rotor on my original 19'' front is a 10'' w/ a 2.4'' diameter center. The rear accepts a 2'' diameter rotor.

Can I just bolt on the rotor even though the center diameter is too big? Or do buy special conversion spacer or a 10'' outside 2'' inside diameter rotor?

Thanks.

 

The wheel you bought is made to be used on bikes with the older tapered roller wheel bearings. Your bike obviously has the current spec ball-race bearings, which have a larger OD, hence the larger bearing housing and larger hole in the rotor. No, do not use a rotor with larger hole - it is intended to centre the rotor on the hub, the screws simply hold it on.

 

Ok thanks. They guy I got this from pieced it together so I am trying to figure out what I have/need to get it the way I want. The rear wheel/tire that came with it is the old style also because it has the smaller diameter hub. After I lined the new wheel up in the forks it looks like I will need either a spacer/adapter or a new caliper to match up both up.

I was hoping someone has done this swap before and could give me a heads up on what I will need.

The frame is a 94 XLH sportster if that helps at all.
