I got a chain conversion swing arm late last year and just now getting ready to install. Gave the rear wheel ,new spacer and bearings to someone to install. He is going to machine out the center of the wheel to accept the new spacer and called me and said the bearings are not as thick as the stock ones. Is the new spacer longer or do the new bearings get pressed in further? Appreciate any help.

It all fits correctly after machining the wheel center out. Just assemble the same as the old one the new bearing and spacers all fit as they should.

I don't understand the deal here. Are you converting an 1125 to chain drive?

If I buy the 1125 chain drive swingarm kit from EBR would I have to get my rear wheel machined to fit? If I get the kit and the mag wheels, would the mag rear need to be machined to fit?

I am curious about this as well, on a XB with the Buell chain swingarm, will it use a stock wheel? I have hear both yes and no. Which is it?

On the aircooled swingarm there were several conversions. The early ones just needed spacers in the bearings. The latest version from Buell Racing needs the inner spacer replaced and different bearings, thats where the machining (enlarging the bore diameter) is needed for the larger axle which the 1125 uses too. EBR can help.

Ok good to know, I'm buying a 12 with the newer XBRR style swingarm, and was curious if the stock spare wheels I have would fit. So I guess it will have to be modded.

Building a race bike is not like converting a street bike from belt to chain. Even the best race parts from suppliers like EBR almost always require some fitting. As stated above, the EBR 1125 swing arm conversion uses a larger center spacer. We are using a stock wheel and had to bore the center out a little larger, not too sure that would be needed if you were building a mag wheel.

We also have an older style XB arm modified by Revolution Performance and a newer one from an XBRR I think they can use use a stock wheel, but both need specific spacers for the new configuration.

Bore the stock wheel hubs to 1.800 inches to allow the chain drive kit inner spacer to pass through.

The brake side bearing goes in first and gets pressed fully into the counterbore.

Flip the wheel, install the inner spacer, and press in the sprocket side bearing until just touches the inner spacer(starts to build pressure in the press). The inner spacer should be snug to the inner bearing races, not loose, but not too tight or the inner races will be preloaded.

For bearing installation it is best to press only on the outer race.

Spare wheel kit part numbers are G0635.08AZ for the 1125 and G0635.10AH for an XB.

Was the decision to use a belt for the 1125R a H-D thing ???
