Brilliantly stiff suspension, improves the handling and braking feeling 10 fold compared to standard.
Brilliant for stoppies too.
It is a big job and ball ache, but it all depends on what forks you've got. It's luck of the draw in most cases.
If you're lucky like calcumface, you won't have to do much modding. On the other hand you may need to get a wheel spindle made up, which is threaded on one side and a sleeve made to slide over it for a perfect secure fit, as if it's made to be like that from factory.
The turning circle is also better/the same, this was one of my worries doing the upgrade because on the difference in side to side with the steering, but all is well.
I'd reccomend it to anyone who has standard forks, they're shít in comparison.
Just make sure you shop around and get a good set of forks/yolkes that aren't battered/pitted.
Best case scenario you will just have to have an extension made for the headstock + a brake caliper bracket, which is cheap and easily done.
To fit my big husky forks i had to have the yolke bored out to fit the DT stem and have a wheel spindle/sleeve made to fit the excel supermoto rims.
In theory you'd think it would be a lot easier if you could get the bearings, but the sized beaings you need do not exist they're the odd size of odd sizes, so don't even bother trying.
All in all i'm super happy, because i know full well it's a perfect job and fitment with no shortcuts or bodges made to make them fit.

Cheers lads, a lot to think about.. I can't wait to get started! My YZ rear end should be here tomorrow though, along with new bearings for the yz front wheel, so i'll be playing about with them first.
I will be keeping it enduro Liam, can't be missing out on all that off road fun!

Getting ever closer to ordering the parts to do my own USD conversion, I phoned yam uk to try and find out what part are interchangeable between the DT and YZ...The technician couldn't help me that much, other then to tell me that the part number for the brake discs on the YZ didn't change between 90-01, and that every other part involved changed part no. near enough every year. He said that I would have to go on trial and error, but also all of the forks are the same size (except comp ones) , so should fit any year yokes. So going on this im presuming that the same calipers were used throughout the 90s? If any anyone can confirm this, that would be great.
He also said that it wouldn't work very well, as the clearances between the tank and radiator etc is smaller on the DT then it is on the YZ... So I thought I would start this thread to find out if it was worth it? Was there a lot of work involved? Best method, pressed stem, collar, etc? And how has it affected the performance for the good? ..and the bad?
Absolutely wicked bruv. Better rebound. Stiffer suspension and better handling. But to be fair that might also be down to the supermoto wheels.
Ask enny how easy it was.
It does mean a bit of fooking about mate.
My way more than others but thats what its all about. I'd definitely go the bearing cup route again. You raise the height of the handle bars and the overall height. You'll want a jack up kit to go with it. Otherwise your dt will look a bit silly.
It's a nice conversion but not for everyone. For road use you probably won't notice much. For me it was purely an asthetics thing. Theres nothing wrong with the original setup to be fair. I just wanted to supermoto my dt and thougbt i might as well USD it.
Its expensive. Can take time and a bit of trial and error.
Best to get everything off the same bike and year matey.
So if you buy forks from a yz250 2003 make sure you get the spindle and yokes as well.
Then you can either press the stem out of the dt yokes. And the yz yokes. Press the dt stem into the yz using a collar to compensate the diameters and press on new bearings and voila. That should be you done.
Or feck about making bearing cups and use the exisiting yz stem like me. Although my bottom bearing didn't reach the race. So i've had to press that bearing off. Put a 2mm spacer behind it and press a nea bearing on.
Good lad!!! We'll be the special ones with the only dt's in enduro trim rocking USD forks!! What you mean yz rear end? You got the swing arm and shock? I've got a yzf rear fender I need to fit just need a tail tidy!!

DT shock should fit, there is one included in the sale that not in the pic..
I paid £150 all in, The fella I brought it off had had it fitted to his 97 DTR so it should be a very straight forward swap. I haven't decided whether or not to try and polish it up to a mirror finish or not yet, I guess I should wait and see what condition it turns up in first! haha
Yeah same hubs. But that doesn't mean the front and rear wheels will be inline mate. It may have a smaller gap between the wheel and thus smaller spacers.
Nah but i hope you got decent information out of it.
Personay i've never taken my bike so far that the usd's have been beneficial.
Like i said. Nothing wrong with the original setup. You can even just put thicker oil and stiffer springs in if its too spongy. For me the USD's were purely aesthetics. .

Still easy thougb. Just more hassle.
Nice ride height though. Longer yokes.
"Bruv", Oh dear cal, Oh dear. Other than that good bit of info ;)
