This video covers a fork/shock USD (upside down) upgrade for a 99 XR400.
I took the front suspension assembly from a 2006 Honda CRF250 and installed it on the XR400 using a conversion steering stem from XR's Only and a Pivot Works bearing kit.
Part Numbers:
Steering Stem:
- XRSS-CONV
Steering Stem Nuts:
- HO53229-MN1-670
- HO90304-KA3-710
Pivot Works Bearing Set:
- PWSSK-H04-420
Also bought this stuff for a 2006 CRF250 off ebay:
- set of front forks
- full triple tree/headset unit
- front wheel/tire combo
There are a few ways to do this conversion.
* You can buy the steering stem from XR's only that fits the CRF triple tree and allows you to use stock XR headset bearings. (easiest route)
* You can buy some custom bearings that will fit the stock CRF250 steering stem and the races will fit the XR. (the bearings are smaller though and require spacers otherwise the stem will be loose top to bottom)
* You can machine the CRF stem to a smaller diameter so that the stock XR bearings will fit the CRF stem. (cheapest if you have access to a lathe and the knowledge to use it)

This is the best video I've found regarding Honda XR USD/inverted fork conversion. Thank you! I had to resort to internet forums when I wanted to swap my old XR250 and ended up buying old CR500 triples and cobbling together parts to make it work. Good job!

@MakeFixUpgrade 2 месяца назад

Thanks! Glad you liked it! I had to hunt for info as well so figured I’d make a video for it.

@Crxpert1 Год назад

Very helpful. Thank you! I Love that you included part numbers.

@MakeFixUpgrade Год назад

Thanks! Glad you like it!

Based on what I found, 2005 - 2007 Suzuki rmz triple tree fits, stem height etc. The conversation bearings ar 30x47x12 and I used a thrust washer spacer for a perfect fit. Now any 47mm fork should fit 💪👉👍🤞

Thanks for the video I'm in the process of doing this swap myself

If you have any questions let me know!

@@MakeFixUpgrade any chance you could provide links to the exact parts you ended up using?

@@tomcooley6019 the part numbers are in the description. I’ll see if I can track down the links tomorrow.

Nice job

@tben9357 Месяц назад

Thank you so much for the vid! Do you know if this same setup will work on a 96 xr400 also?

@MakeFixUpgrade Месяц назад

It should work on any xr400. I believe they’re all the same for the most part.

@munoz20 Год назад

nice video man

@munoz20 Год назад

post riding videos would love to see a walk around and ride of your 400

@MakeFixUpgrade Год назад

Thanks! 🙏

How was the balance between shock and forks? What are your clicker settings on the suspension? Cheers!

@MakeFixUpgrade Год назад

The balance felt good to me. I don’t recall the clicker settings. This was a project bike that I bought to rebuild. I have since sold it.

@hadrienaubert7 5 месяцев назад

Hi, are you still happy with your fork swap ? I was thinking about replacing spring by stiffer racetech in addition to racetech gold valves, especially in order to keep original fork and look.... but I'm still in reflection time ^^. Thanks for your feedback.

@MakeFixUpgrade 5 месяцев назад

I liked it while I had it but have since sold the XR and switched bikes.

@nonoantonio98 Год назад

very nice. how much clearance do you have between the forks and tank?

@MakeFixUpgrade Год назад

It just touches the tank. I’ve seen some where you drill the lower clamp and install stops but I didn’t do it.

@pcduc64 7 месяцев назад

so. . i guess my question should be is, the pivot works pwssk ho4 420 the smaller bearings for the cry stem and the xr race?

@MakeFixUpgrade 7 месяцев назад

The pivot works pwssk ho4 420 bearing set is used if you buy the replacement stem from XRs Only website.

@kyleclosen622 Год назад

Wondering how the headlight mounted up the CRF triple clamps? Or does it just mount onto the tabs onto the side of the clamps?

@MakeFixUpgrade Год назад

Headlight mounted fine. No modifications needed. The rubber clamps fit perfectly.

@pcduc64 7 месяцев назад

I need the part number for using the crf steering stem on the xr400

@MakeFixUpgrade 6 месяцев назад

I replied to your other comment with details of where I got the bearings.

@pcduc64 7 месяцев назад

What is the part number for the thinner bearings to use the crf stem..? Thx

@MakeFixUpgrade 7 месяцев назад

I bought the thinner bearings from TWF Racing. I emailed Zoran at twfracing.com and told him I was looking for bearings with the measurement 30mm ID X 47mm OD X 14mm thick. He gave instructions for how to pay and shipped them to me. I actually still have several sets and some spacer washers as well. You can dm me on IG @make.fix.upgrade if you're interested in them.

@paulh.5691 11 месяцев назад

Why not apply some heat to "the triple tree" to put the new stem in?

@MakeFixUpgrade 11 месяцев назад

It’s a pretty snug fit. You might be able to heat it and beat it but the press works great.

@GahBoe Год назад

What sort of terrain did you ride with the XR400? Think it was worth upgrading to the larger USD forks for trail riding?

@MakeFixUpgrade Год назад

Mostly local trails and fire roads. I personally like the USD shocks better but I wasn’t unhappy with the XR forks. I felt the USD upgrade provided better handling. I’m not always trying to ride at full capacity though. If you have the cash to do it it’s a fun upgrade.

@jamesbramblett3346 Год назад

How much longer are the CRF 47 mm forks than the stock XR 400 forks? And how do you compensate for this? Can you just run the forks higher in the clamps enough?

@MakeFixUpgrade Год назад

I believe the CRF shocks are about an inch longer. You can run them a little higher in the clamps if you want to. I'm not but there's some room.
