I have been searching thro this forum for a few months now and ive noticed a few people have done this mod in a completely different way/more expensive way than jase's. Im absolutly gobsmacked at how easy this wheel modification can actually be.Ive been hearing alot about hubs being re-centred etc etc and i was begining to think id wasted my time and money searching for a set of XTX wheels.BUT after getting a PM from Jase and chatting to him on the phone im quite happy with following his advice. What i shall do, Once ive started the modification, is take some pictures and write up an explination of what i have done etc etc so it makes it easier for other members to carry out this operation. If an admin wants to place the write up as a "Sticky" thread once ive completed it i think this will help out alot. All i can say now is TOP MAN JASE! you've helped me out alot buddy! |
I am sure Kev will add the modification to our mods charter if its well done and documented.

I have another question regarding this wheel change........ :smilies0119: sorry for the constant questions guys......
Are the bearings etc etc on the XTR wheels the same sizes as the XTX wheels? Im going to have to swap it all over from the XTR to the XTX wheel if they do fit. Cheers.

I would get new bearings and not use the ones out of your R as you could damage them getting them out ,they are cheap enough to get new

At the moment they havent said if they are going to repair it or right it off as it is so close with the money ,i personally would like them to right it off then maybe buy it back off them if the money was right ,as i would feel at a loss if they repaired it themselves as it would show up as an insurance right off when i came to sell it also ,i bought a brand new bike and it would'nt be the same as a repaired bike |

I registered about a year ago, and I was chatting to you about buying an XT660R and having wheels to swap around the same as your conversion. I've never got the budget together for a 660, so I've bought this, http://www.xt660.com/showthread.php?p=114248 Anyway, sorry to read this and see that you and your XT have been in a crash, shame because as a bike that was converted and could switch between supermoto and enduro, it must have been quite unique. Cheers Col. |

These two bikes are designed for different purposes and they are set up accordingly. I have no experience of the above conversion, but, the XT (or any other bike) can be modified in a two simple ways to change the handling. For more high speed stability it is generally better to have more "rake/caster angle" and "trail". The opposite is true for quick turning. Please excuse me if you already know this: "Rake" or "Caster angle" is the angle between the vertical and the steering centre line. "Trail", if you imagine a line drawn through the centre of the steering head to the floor, then measure from that point to the centre of the tyre contact patch, that is the trail. It decreases when the rake decreases. From the Yamaha web site:- XT660R Caster angle 27.4 Deg, Trail 107mm. 225 mm fork travel. XT660X Caster angle 26 Deg, Trail 94mm. 200 mm fork travel. http://www.yamaha-motor.co.uk/Images...m46-326368.jpg http://www.yamaha-motor.co.uk/Images...m46-358219.jpg If you study the two pictures above you will notice that the forks are completely different. On the R the spindle is in front of the forks, on the X it is underneath. This produces more "Trail". The smaller the trail figure the easier it is to turn the wheel. The greater it is the more stable the bike becomes at speed. If you think of a shopping trolley. The wheel is offset from the "steering" centre so no matter there the wheel is before you push it, it always ends up straight when you push it. Thats the effect of trail. So: If you put a smaller from wheel on your R, you will lower the front of the bike and as a result decrease the rake and trail and the bike is likely to be less stable at speed but it will turn very easily. If you still want to do it and find that the straight line stability is not so good, you could try lowering the rear to compensate for it. A quick rough calculation of tyre and wheel size give an R wheel a diameter of 713mm and an X of 600 mm. Half of that for each (i.e spindle to edge) is 356 for the R and 300 for the X. So fitting lowering bones to give about 50mm drop would be about right. On top of this, the brake disc is smaller on the R for a very good reason, on a dirt bike you do not want the bike to be overbraked as it is designed to be used on loose surfaces, whereas the X is primarily for road use where there is a lot of grip and this can be used to stop quicker. Hope this helps - if anyone thinks I am talking crap - please let me know. OGR |

:newspaper: Good reading Ray.
One can also add spacers in the forks, or lower the forks through the triple clamps by 5mm. |
I agree with the above comments, that's a well written and informative post, good stuff Ray!

Thank you for help.
I bought used X wheels (Whole set; rim's, tyres, brake discs, cogwheel etc...). I put X wheels to my R. I did following modifications: Front wheel: -R's brake disc is in use -Front wheel was about 5mm too much on the left (brake disc side). Local dealer re-centered wheel by setting the hub correctly to the rim (The spokes have re_adjusted) -Front fork spacer (25mm) Rear wheel: Modification no needed Other -OTR lowering links (-30mm). I'm only 172cm, so lower bike is better to me anyway. -Adjustable side stand -smaller supermoto front fender Enduro tyres are Continental TKC80 and they are quite poor in high way speeds. Supermoto tyres are Metzerel Rennsport and bike is very stabile and nice drive on asphalt road. Now I have supermoto and enduro :) |
guys I am still keen to try and put supermoto wheels onto my Z, will the front wheel from an X fit ??????
I can get a sticky rear tyre to fit my rear 17 rim so really I only need to convert the front wheel from 21 to 17 I just fancy doing this and I dont think there is a modern Tenere yet with supermoto wheels fitted so I just thought it would be fun. I will run supermoto fun in the summer then grippy mud tyres in the winter with the 21 front. any ideas maybe its too much bother or maybe I could just get a 17 front from another bike ???????:BaseballHat_LNY2EG: |
Might be converting my XTR to use XTX wheels. Any new updates regarding this? Too bad its a pain to get hold on used XTX wheels here in Norway/Sweden...
|
Ok can i fit a 17" wheel to my xtz keeping the z forks?:woo:
|
Hiya guys!! My dumb question is whether I can go the other way ie can I fit the XT660R wheels to my XT660X??? It sounds like I could providing I have a complete set of wheels and discs and calipers from the R?????? I could then use the R wheels with semi knobblies for the winter and fit the X wheels with normal road tyres for the summer. Thanks for any comments.

Just spotted this thread after starting another! Sorry.
You guys who have fitted an X rear wheel; any problems fitting a 150 rear on it? It looks like a 160 might foul things but it sounds like you all have no trouble? |
