I know this discussion has been started before, but I want to know what is used for the rear brake? Do you use the XB rotor and caliper or just the rotor. From what I understand the rear axle from my X1 is what I will use, doesn't there have to be a custom spacer made? Is there anyone who has done this, or know where I can find some information. I have the front end things figured out, now I just need to get the rear figured out and I will be starting in a few weeks. | ||

I know that the rear axle diameter is bigger on the XB. Perhaps bearings with smaller inside diameter would be most easy way? | ||
| Sjh |
That is what I was thinking. Anyone know if the stock rotor is used or if it will even bolt onto the XB wheel? The parts that I am purchasing have not arrived, but I thought someone here would know some specifics or even done it before. | ||

I too am interested in doing this swap. I wonder if any company would be interested in offering a swap kit (American Sport Bike maybe). I don't know about the rotor, but I've seen pictures of Sanchez's bike and it has the XB rear pulley. | ||

Yep, I am wanting to do the swap as well... Chase | ||
| Daves |
I'm working on it | ||

If the deal does not fall through I have everything coming that will be needed to do the swap. I have obtained some pics of a bike that was already done and the XB rear rotor is used. Is the XB rear caliper the same as the tuber? I cannot tell for sure by the pics, but the stock tuber caliper carrier is used. If anyone finds any more info please share. | ||

Didn't the bike sold by Jack Reinhart(sp)?? from Buell have the XB wheels of was that just the front end swap?There was just a couple of pics floating around last week as someone just bought it and posted here. | ||
| Sjh |
yeah, I think the bike went to georgia. I asked him to send me some pics, so we'll see what happens. | ||
| Eboos |
Sanchez now own's Reinhart's bike. I have sent him a message about it. Yes, it has the XB rear wheel and pulley. I have heard that the stock caliper would be used, and I think the XB rotor too. | ||
| Sjh |
Yes the stock caliper and carrier are used. I would like to know about a spacer, what size is used or if the old one can be used or modified. | ||
| Eboos |
Bearings and spacers should be the only issue. I could probably figure it out pretty easily if I had a XB rear wheel right now. Does the 04 and up XB pulley use the same belt tooth pitch as a 96-02 tuber? | ||
| Sjh |
I am assuming that the conversion will dramitically gear the tube frame buells down with the 65 tooth rear pulley? Is the stock belt long enough and is there enough forward adjustment to use the stock belt? Hopefully my parts are in the middle of next week and I can begin some mocking up. | ||

A 28 tooth front pulley should maintain about the same ratio as a 26/61. It may be just a bit slower due to the new tire size (180/55 as apposed to 170/60), but I don't think that it would make a noticable difference. Based on my calculations, the rear wheel of a tuber with stock gearing and a stock rear wheel should travel 30.78 inches for one complete rotation of the front pulley. A bike with the XB wheel and 28 tooth front pulley should travel 30.43 inches. A third of an inch at one rpm would amount to 1000 inches difference in fourth gear at 3000 rpm. Nothing significant. | ||

That's less then 1 mile per hour. Man, I'm a geek. | ||

found a pic, has a nice clean look  | ||

So the XB forks are the same diameter as the tuber forks? (ie. you can use the original triple tree?) | ||
| Matty |
If you use the '03 XB forks, they will work with the 54mm triple trees from the S2,S3,S1, and X1. The later XB forks have a larger bottom diameter so you'll need to bore the lower clamp to fit them, but they will also work with that modification. The pic above uses the XB triple clamps and alters the handling characteristics of the M2. | ||
| Eboos |
I was told that the XB forks have different tube spacing then the S1,2,3 and X1. You would have to swap the complete front end. | ||
| Matty |
There is a difference in offset between the stem and forks which affects the amount of trail, if that's what you mean. (?) Using the XB trees will make the bike feel "lighter" since you would be decreasing the trail. Or are you are talking about the different spacing for where the trees grab the forks,? The older trees will work - you just slip the forks up a hair or three. I've not had any luck finding a 25mmx55mm bearing for the rear wheel, so I ended up needing to have spacers made. | ||
| Sjh |
Thanks Matty for the info. Well most of my parts arrived, now all I am waiting for is my S top tree and headlight hardware. Should be doing some mocking up within the next few weeks. Anyone else in the middle of this process that can post some pics? I have also considered using the XB cluster with on the X1, and just identifying and crossing the wires to the correct postion. Would all of the sensors be the same if I was able to hook everyhting up? Would there be any issues with incorrect readings? | ||

Sanchez now own's Reinhart's bike. I don't have many technical details since I didn't build the bike myself, but I'm happy to provide pictures if anyone wants them. | ||

Dirty sanchez i want pics Been thinking about this for a little while, but i want to see it before i try it R | ||
| Sanchez |
Here are a couple of shots I took this morning:   I love the naked street fighter look it has. | ||
| Eboos |
Sjh, did you get your parts yet? Sanchez, can you post some closeups of the rear wheel (profile from both sides, rear view from inside the swingarm showing any spacers on both sides of the wheel), front pulley and idler pulley (if equiped)? Could you also write down any writing on the drive belt (maybe there is a way to identify where the belt is from by the writing)? Thanks man, the bike looks pretty sweet next to your cobra. | ||
| Sjh |
have all the parts, except top tree, headlight, windscreen, and brackets. Should be done with everything within a week after I start. Just waiting until I get done with school next week. Sounds like I will be getting rear spacers made, but I also have to see if my wheels have the updated bearings or not. I am also still considering what trees I am going to use between stock and XB. Matty: does it matter between trees for performance or is it just individual preference? I am not familiar with the +/- of increasing or decreasing trail. | ||
| Eboos |
Please post the specs of the spacers when they are made. An AutoCAD file, or a pdf would be cool if not asking too much  . | ||

Here are a couple of shots of the brake side from inside the swing arm. I couldn't get an angle on the other side to get a good shot around the sprocket.   The only marking on the belt is a Harley logo.  It's completely pully-less. the bike looks pretty sweet next to your cobra. Thanks.  The Cobra is a bit faster than the bike (at least in a straight line), but the Cyclone makes up for it by getting 40 mpg instead of 13.  | ||
| Eboos |
The only thing that I notice is a spacer on the pulley side, which is probably the same as the stock spacer. Maybe a bit shorter, I'll have to look at my bike. | ||

there is some 2004 XB forks on ebay for 200.00 forks only no trees |
