Topic: Harley wheel on a GSXR front-end

[Elan]

I would use some heat. 


Do you happen to have a welder? You could stick a pipe through (axle sized) then tack it to the bearing, then hammer it out.

The heat did it. I wound up bringing it to Brooklyn Moto and they put it on a hot plate for half an hour. It still took some real banging with the blind-hole puller. My creme crème brûlée was not effective, to say the least. The 21mm-thick Harley bearings are no joke.

The crush tube is 77mm long with an outer diameter of 25.5mm...It makes a decent guitar slide. It seems like the replacement tube will need to be only about 1mm in thickness, as the inner diameter of the hub isn't much larger (I can't get my calipers in to measure).

Here's a shot of the hub, and a dead-on shot with the crush tube in the center:

I think I've just about given up. My last motivation for getting the Harley wheel to work is to get precise measurements so someone else can duplicate the work...Thing is, dollar for dollar, the custom hub is a better solution and it might make more sense to just support that guy.

Ah, well once I get my spacers made I am sure the guy who is doing mine may make an extra set.. Not sure what he may charge for it though... My total cost has been only the wheel. What set up are you running again? I have my hayabusa rotors already mounted as well.

A finicky thing about these Harley hubs is that each can be slightly different, and there are so many model years that it would be very difficult to figure it all out without each kind of wheel and accurate knowledge of which model they all came from. This is in addition to the simpler fact that from 2000 on you might have 3/4" bearings, 1" bearings, or 25mm bearings. I've found that the crush tube will need to be something like 1mm if I use 25mm bearings in my 3/4" hub due to the fact that the diameter of the tunnel running through the hub isn't much larger than 25mm itself. If had started with a hub with 25mm bearings, I'd be ahead, but they were very difficult to find. Even 1" would have been significantly better, even taking into account replacing the bearings and crush tube.

I planned on using 300mm Harley rotors, which means I'd use older gold Tokico calipers with my newer forks with a 4mm spacer as per this glorious post.

Following this thread, I've got a 2007 GSXR600 front end complete and I'm putting it on a yamaha tx500. I was hoping that the VSTAR1100 custom front spoked wheel I have laying around might be a hack/shortcut but the hub is much too wide to work.

I'm not opposed to buying the machined hub listed above but would prefer something as cheap and elegant as a harley front wheel that fits with a bearing and rotor swap.

Is this idea still viable to anyone or are we looking at a dead end here?

If it is dead does anyone have any other ideas?

I got to the point where I could do it if I knew the width of the axle spacer that would center the hub in the forks. I couldn't find anyone to give me measurements for the Harley or GSXR parts.

Note that the Harley solution can hardly be called elegant, and I have yet to read of a successful solution that didn't involve some machining in one place or the other.

Cheap and practically bolt on I almost always find a certain elegance in lol, I understand your point though. My GSXR front end is shipping, when it arrives if there are any measurements I can take for youu let me know.
