I've searched but havent found my answer. In looking through the galleries and other posts Ive noticed some people have spoked wheels. How are people doing this? Is this an xs swap? Also, what other options are out there for spoked wheels? I hope to be going either 17's or 18's front and back.
Thanks in advance.

Alright, so with more looking I have found a couple answers to my questions. Only the front xs wheels works as it shares the same diameter axle bolt. Am I correct in assuming that XT500 wheels will work?
I saw a couple of people on here have 18x2.25 fronts, and 18x2.5 rears. What did they use? I would like to only use items that are from US models.

Hi, You can use the rear as well, but you need to either sleeve down the bearing inner races or have the axle slot in the SRs swing arm opened up from 17mm to 20mm...neither exercise is overly difficult. I prefer to sleeve down the ID on the inner race of the bearings. See drawing...hope it makes sense...  In making the centre spacer, measure the original and then subtract from that length the amount of the two top-hat bushings that is sitting on the inside of both of the bearings...(say make them 3 to 4 mm each side), make a new spacer that is 17mm ID, (that will allow the axle to slip nicely though...same for the ID of the spacers...). To sum up; the total length of the new spacer, including the thickness of the flanges of the two top-hat bushes on the inside of the bearings, must be exactly the same as the original 650 spacer. In case you weren't aware, the spacer is there to prevent sideways loading on the inside race compared to the outside race when you tighten up the axle nut. Hope this helps. One other thing; as I recall there is a ring that sits around the OD of the 650 spacer, that is there to keep the spacer aligned with the bearing centres for axle fitment. It slips off the old spacer. Make the new spacer the same OD as the original and slip that onto the new one. *If you choose to have the slot in the swingarm widened then I'd take the lot from the bottom of the slot to remove any chance of misalignment of the axle.

Stew, YOU ROCK! Thats a great explanation of how to do that.
Another way a lot of people go is to choose their hub for the front -I chose a Grimeca 4LS brake, and a rim -I chose a DID 2.15 shouldered alloy rim from the rear of an XS650. Once you've chosen those, call Buchanans spokes in California and tell them what hub and what rim you have and they will make spokes for you that will fit perfectly. Lace -up that bad boy, space it out on your front axle and get your cables set up. For the rear, yes you are correct, the XT500 hub will be a match for the 17mm axle. Keep in mind that you will need a new linkage and a pivot for your foot control. I can take pics of my set up so you can see what your up against. The TT and XT hubs look essentially the same but I chose the XT because it has a cush system. This is also the same hub that the Euro and Asia/Australian bikes are delivered with.

Heh, heh... Yes the XT hub goes straight in. The 650 hub has no cush drive either. However I have not found any problems with not having a cush drive in the black cafe racer and I have a TX750 rear wheel in it. The clutch basket on the SR has a series of springs in it to absorb some shock loading. SR |

Thank you guys both for the info.
SR- The picture helps a lot. Ive read past posts where you have explained that, but as I was not familiar with the names of the parts (specifically the "tophat"), just the appearance, it has helped clarify alot for me. Looks to be relatively simple either way.
Troutthunter- Thanks for the heads up on Buchanans. Didnt know such a place existed.
So, now that hubs look to be handled;
(a)can anyone suggest rims to go with? I actually dont mind going same size front and rear as the tire size will most likely be the same.
(b)Any widths recommended?
Laurence

Pictures are much better than words sometimes...
For rims etc. just get complete alloy-rimmed XS650 wheels...fit 100/90 front tyre and a 120/90 rear...much simpler and it saves thinking about such things...heh, heh...
For tyres I prefer the Bridgestone BT45s...excellent tyres.

SR Although this makes perfect sense and is the most intelligent idea, I have to say I've never been known for being smart or sensible. Much too easy  Laurence |

Do the XS rear wheels still allow me to use my rear disc?

Do the XS rear wheels still allow me to use my rear disc? No. Finding a spoked rear wheel with a disc is a mission for many on both the SR500 an the XS650 forum. You can do it but there is no known plug and play. |

Omars- omarsdtr.com/street12.html has a kit to convert a front wheel to a rear wheel. It would probably work on the spoked wheel as well as the cast wheel. If you were going to spend that kind of money you might want to look into flattrack supplier and a purpose built wheel. Check out the xs650 forum but remember they have solid mount sprockets on their wheels. xs650temp.proboards29.com/index.cgi I think the cheapest solution is to convert the rear wheel to drum. |

I think the cheapest solution is to convert the rear wheel to drum. Werd. I understand wanting the rear disk for aesthetics, but for real stopping power I think a dual disc conversion upfront is the answer. |

There is a rear disc wheel available from a Yam RD250C/D model, but it's hard to find. I think that some of the similar model 400s are also the same...I can't confirm that last one though. The C/D model RD though is not an entirely common model, as of course you'd expect when you want a quick fix...heh, heh... The Japanese use a rear hub from a TDR250 twin...not a real easy hub to find either. I am fitting a DR650 Suzy rear hub to my 'new cafe racer'...not entirely a simple task and I'll keep you all up to date with the mods when I get there. I'll post the info on the 'new cafe racer' post on the on the Bike Projects area... sr500forum.proboards38.com/index.cgi?board=projects&action=display&thread=1160903565&page=4SR |

Speed2xs,
Before I decided to keep the cast wheels on my '79, I had the idea to use the front and rear spoked wheels from a late '70's Suzuki GS750. They are not a direct swap but if you want to tinker could be made to work (and the Suzuki rear has a built in cush drive...). If you are interested in the parts I have accumulated, ping me off list.
