front fork MUTATION xtr>>xtx 07 stainless body
 

this is my modification that i had make for my xtr>>xtx MUTATION, i show it because i dont saw nothing for this modification, and now my bike its funny and fair....xD!!

sorry for my english :(

This looks super! Where did you get this? You made it yourself? Or is it from some other motorcycle??

That just looks like the lower fender has been removed.

Plus the addition of the supports and forks brace which does not exist on the R.

Do you mean the metal frame thing between the forks?

Yes - it is a forks brace which the X has but because the R wheel is 21" there is not room for a straight one on the R so they do not put one on at all.

Why they did not put a curved one (curving over the tyre) I do not know. Perhaps there is no real need for a brace and the X one is cosmetic or is the R at some risk of warp under load because it doesn't have one?

There exist so many minor differences between the X and R models that are not apparent to the casual observer - the rear suspension link bones being one - that one wonders why are they different? (The link bones probably to set the suspension level as a result of the front wheel size and geometry differences putting it out of level).

:thumbsup[1]: to rekainen for a splendid job in doing what he wanted.

Ahh, I only just noticed the xtr>>xtx in the title, I thought it was an X all along.

Does it act as a brace or just a bracket for the lower fender? I'm guessing they didn't put on the R as it was designed as 'off road' and didn't want it to get clogged up with muck (like it would on the Z?)

Well done though rekainen :thumbsup:

IMHO the brace is needed on the X, especially once you have fitted a decent brake pump. The swingarm twists under heavy breaking otherwise. Even the standard brace of the X is not strong enough under really heavy breaking.

Parkez did convert his R into an X and changed also the brake pump. The brake caliper did touch the rims when he braked hard (not under normal riding conditions)

im sorry for not explain this item because my inglish is lamentable and i cant undersantd your questions... :( but this front fork upgrade is necesary for torsion effect produced when you brake or take a hard curve....((nein menos mal q les has dicho algo por que no tengo ni papa de ingless y esto es pesimo)) this is the spanish explain ^^ sorry again... http://www.xt660.com/showthread.php?p=65549#post65549

its a laser product the most economic solution for torsion effects when i changed xtr>>>>xtx
i dont know any people what had needed this item and i dont konw if this problem is in all changes.

Tell us where did you bought this?

Greetings from Holland,

Marcel

As far as I know he designed & made it himself.

Would like to have one too!

Im looking at doing this myself.Does this also mean the rear wheel from the X will fit to the R's swing arm?

secrets of the mutation. ^^
 

1) Wheel spacers
2) brake spacers
3) stabilizer bridge

sorry for the English
good bye and good luck!!

Another great post rekainen thankyou!

So i need -

• 2no brake spacers 25mm +-0.0 x 6mm +- 0.0 tolerence ?
• Also need to buy the XTX wheel RIMS and make them fit to my XTR hub (Central)
• Make 2no (or just 1?) spacers (bushes) 32mm Dia(Diameter) x 17mm Id (inside diameter) to take up the space either side of the XTR hub? What length are these/this?
• The wheel bridge isnt important so i can just make a bracket to support the mud guard or will the front wheel fit ok without modifiying the guard?

Not to sure if i have got all this correct so please let me know if i am being stupid/dumb. :laughing11:
Thanks again.

if you use a complete XTX front wheel than just recenter the front hub the make it fit (loosen spokes, recenter hub, fasten spokes). Use the genuine spacers that came with your xtr. The xtx rear wheel fits without modifications.

sorry for my English, it is best to talk with marjani, though what I understand, marjani use the wheel of the xtx, may be a solution, although slightly more expensive.

+-0.087 tolerance error for parallel faces

marjani modifier is a pro, I am a little amateur in these things.

sorry again.:sad7:

Ahhh ok i got you now guys....i was looking at doing it the mor ecomplicated way but i see now.
Just got to get the XTX wheels now,did see a pair of wheels, without tyres, for XTX for �250 starting bid and �350 buy it now,does that sound a good price?

bought my xtx wheels round 350GBP so sounds like a fair price to me. The discs were still on but the front x disc is unusable. Buy yourself also an extra r front disc + sprocket (46). This will shorten the swap wheels time.

Would it not be easier to buy the forks and exchange the forks inner parts?
Does anyone know if the inner parts of the forks on an XTR will fit into an XTX?

Im just trying to find the cheapest way of going about this modification.

it hasn't been done before. You'll also need the x front brake caliper and disc.

The forks a different, different wheel travel, different caster angles, trail. I would say stay with the r fork. Unless you want to spend some serious money, than go for a WP fork with the OTR custom clamp. Then you need also a new handlebar+brake caliper+front wheel (Excel). On the back than you need to lift the bike with link raisers and put a Ohlings shock (if possible the Ohlings for a XTZ > bigger travel). This is already done by another forum member and make the bike looking great but more important, much better suspension ;)

Old thread, but I'm hoping someone sees this.. :)

I'm in for the same mod here, excel 17 inch 3,5 with an R-disc on R-forks and R-brake caliper. I mounted the rim today with stock spacers on the wheel axle and it kinda fits. I'ts roughly 6 mm offset towards the caliper. Havent got a tire on it and it will probably be tight and i'll have to remove the mud guard.

Any one run this setup without custom spacers? :)



Edit:


Spacers needed are 15-6=9mm and 27,5+6=33,5~33mm or just add one of 6mm.



Cheers!
