XT660Z with YZ forks
 
Hi to everybody, I just want to share my experience with you. I swap the stock forks with YZ front. I using Yz 450 2006 forks, (46mm top, 49mm bottom) triple clamp was from was from WR 450 2005. The size was 44mm / 48mm and I machined it 1mm top and 0.5mm bottom to be able to put the forks in. I using the original Yamaha steering stem. Bolt it without problem, only on the top clamp i have to put 1mm spacer between the stem and the clamp(the original stem was top 25mm, the new is top 23mm. The front wheel is from YZ 450.I also changed the handle bars with 28mm. What is left is a brake caliper(YZ 450) oversize brake disk 270mm, brake hose line YZ and I am done. I did today a test drive(without front brake, just to see how it is - what a difference, now the front is not diving as before. I need to change the rear shock because now is so soft(compare to the front) and lift it with new bones (35 mm) The YZ front forks are 40 mm longer than the stock. I should be ok with the new bones on rear. A proper test drive I will make next week when everything is done.
p.s I don't know how to upload pictures, if somebody tell me how to do it, or give an e-mail to send it, no problem to do it.

DITTO!!! i really want a better front end, i love the Ten but i think the forks are the biggest let down. SO are these YZ forks making the bike taller?

looking good - what you going to do about a mudguard?

did you get the fork internals serviced / re-sprung as the Ten is heavier than a YZ (or are they fine as standard)

Would look nice now with Excel rims front & back :)

The mudguard is on the way(touratech) the rear will be excel to, I am looking to buy it.
The front forks are re-sprung and set for supermoto(rider 100kg exactly what I am) and they are perfect. I bought it already done from ebay -was a good deal about 130 euro. The tripleclamp was 50 euro. The problem now is that the rear is so soft. I will change it with Ohlins and lift it wit 35mm bones.

:clap: Nice work, looking good and unbelievably cheap too!

phil ten 16-11-12 17:13

Good work fella.

So am i right in thinking there is a few different "front end" swaps you can do on the Ten?

KTM 450 forks
Triple clamp from OTR

or (the orginal post)

YZ 450 forks
WR450 triple clamp (with adjustment)

Or (this is more of a guess...i tihnk i read it somewhere? :) )

KTM 450 forks
KTM 990 tripleclamp

Or

The whole lot from OTR.....if your loaded! why is it SO much?

I guess its important to remember when doing this you also have to think about brake calipers and discs.

Would be good to try and pool all info together, would make a very interesting & useful sticky? just an idea

uberthumper 16-11-12 17:57

Why so much? Well, you get a brand new set of forks, brand new yokes, and don't have to have access to a machine shop to make it fit together.

Don't know about 990 yokes. Stoic Bloke did his with SX yokes and a custom steering stem.

I also thought about KTM forks at the beginning but the price was the one rip me off. Now as more I am thinking, and see how everything fit with a little adjustment I happy that I choose YZ. The brake caliper I already have(90 euro second hand from ebay - perfect condition) the disc (single) oversized 270mm including adapter I bought for 150 euro (new). The only expensive think I have to buy is Ohlins rear shock, about 800 euro.
I will send detailed report with pictures when I fit all components.

looking good.

How you finding the 270mm front disc? i would of thought something like 305mm would of been better? do you ride carrying weight?

What exhaust have you got?

I still riding with the original 250mm disc. It's ok but It need more force on the lever. I plan to change it with 270mm and think that for my tip of riding(alone light weight luggage) will be enough. I choose this because there is not so many options. Another is 320mm but made in China and I am not sure. Also I am living in Germany and import 320mm from China will add me custom taxes and... How you plan to swap with 305mm? What wheel you have? I am with original YZ excel rim.

That is a top job!

With respect to brakes, there is an option made by an English company, EBC Brakes, that you may find local to you? If not, below is their online shop with the kit for �169 which will avoid customs issues across the EU.

I believe Talon make a 320mm kit as well, but I was unable to locate an example when I performed a quick search.

I have seen one of the above options used on a BMW F650 Dakar with a YZ conversion.

Thank you very much for the link, I sent them an e-mail, to ask is it possible to ship it to Germany

Sounds a nice job,i cant get the pics.:Itching_KFKKYE:

After reading this thread, I'm about to tackle this mod. KYB forks will be just as good and a hell of a lot cheaper than OTR's WP kit!
I think i have all the bits and pieces, but the main parts I have are...
07 YZ450F forks (re-sprung and valved for the extra weight)
09 WR450F stock triple clamps (apparently the forks will fit :s) - later upgrade to a billet set of triple clamps and get a steering damper.

Ramarvarna (or anyone else who has done this mod) can you explain to me the spacer needed for fitting the the WR triple clamps. A close up picture or drawing would be good too if ya can be bothered :). Is it just a flat washer type spacer, or is it a part which will have to be machined? And where does the spacer fit?


I just have a stock YZ front wheel and might upgrade later. OTR's WP kit uses a 1.85" wide front wheel. Do you think the wider wheel will have any benefit or advantages over the YZ's 1.6" wide rims?

Cheers,
Tim.
