125-200cc WR 125 Upgrade Kit Issues

Hi Guys,,

You may remember my posts some while back with my new (April 25 2009) WR 125 power band issues. Gerald at Upstate in S.C. has all the upgrade kit but the pipe. He suggested me call the BMW/Husky hot line to complain about how long it has taken him to get everything and now the pipe. I work in retail and I know sometimes the comsumer can get answers quicker that shops.

I called Husky and now they say the WR pipes are on backorder from Italy and they don't know when they will have them.

Is the new pipe need to properly tune the bike with the new power valves etc. or is the new pipe just to resolve the clearance issues? I have a few mm between my pipe and shock.

Any help would be great!

Hi Bob. The only issue with the pipe is clearance between the stinger and the shock Nitrogen tank. The new pipe simply re-routes the stinger under the N2 tank. No performance gains from the new pipe.

Since the CR 125's are not getting a new pipe as part of the "upgrade" , I had to summon my vast engineering and intellectual prowess to design a clever solution for our CR 125...

You may want to try this till you get your new pipe. It takes up the slack in the suspension "twist" and moves the shock N2 tank farther away from the stinger by a few more MM's. I've had this on our CR 125 for months now and have seen no adverse effects.

On the 8th day, God created Ty Raps!

Its safe to assume with a redesign..that they probably will improve the power to an extent...shouldnt be a massive difference though...if at all

clearance issues being corrected for sure....thats the main goal..as well as cracks and pinholes


in the interim....take off the original pipe and two area's of contact are evident by wear marks... the shock reservoir....the kickstand...and its also pretty close to the coolant outlet pipe and hose on the RH radiator

I used a small body hammer and using the rub/wear marks as a guide.....tapped the pipe in slightly to get some clearance..very easy to do...make sure you support the back side of the pipe with your hand as your hitting it..to isolate the hits to the area

when installing the pipe... pull or swing the pipe downward (after the springs are stretched into place) to get as much clearance as possible at the hose/rad area....and then tighten the lower isolator first..then the rear one...

some guys have had luck with cutting the hose and also bending the rear mounting tab....but I didnt have to

should be good to go until the new pipe gets here.......

Welp, I stand corrected.

At this point I guess I have no options other than to go ahead and get the power valves and the rest of the kit replace. I'll keep a close watch on my pipe until the boat from Italy gets back from the mother land.

You guys are great to help me out with all your knowledge. Thanks.

WR Bob

I second that!

Not sure if you are asking me about the pipe, but my dealer told me a new pipe was part of the upgrade kit for the WR. He said he's had the pipe and the rest of the kit on order since April. Husky says thay are still on back order and they don't know when they will ship them to the US. I hope I got the story right.

WR Bob

Wow that bulletin clears up a lot of questions. Have any of the new pipes been shipped to dealers? Thanks again for the info.

WR Bob

I agree..perhaps someone across the pond has an installed pic...that we could see...........


I for one would like to know if the silencer swaps from one pipe to the new one....this way I will buy the FMF turbo core 2 now...or not


Personally I think the new isolator on the rear is one helluva idea....it is just me or does that pipe ring like a tuning fork ????? talk about rattle......

Troy, I know you probably know this already, but when you talk about rattle from the pipe, you're not referring to the rattle from the wave rotor on the rear brake are you? At first, when I heard the rotor rattling, I was listening all over the pipe to try and find it.

I understand where your coming from...but its not that


Compared to my CR with a FMF fatty...the wr pipe rings like a bell...if I get the chance when I am riding and not too busy..I reach down and grab the expansion chamber area with my hand....and the noise is gone

things will be better with new pipe with an added isolator at the rear...

Most valuable info.......I thank you for your input


I also notice a sachs shock with the reservoir 90 degrees......hmmm


little changes here and there.......

I knew you were too smart to fall for the rotor vibration... LIKE I DID!!! ... Just wanted to make sure Either I'm too stupid to hear it... or our CR 125 doesn't vibrate in the pipe area... yet.
