This is Steve's SOAS that was bent and seized and had locked the rear end of his bike up solid. From this thread where we fitted a solid tube in his bike for a week.

Inspect you SOAS shaft and check for wear, if it's wearing through the chrome on the shaft, you're on your way to having one like this. Go grab that Bitubo and eliminate the SOAS.

Lubricate the shaft, before it starts wearing. Once there's a bit of chrome gone, It's too late and it will only be a matter of time. I remember seeing a picture many years ago of a mod a guy did. He fitted a grease nipple to the end of the SOAS and would put a bit of grease in it every so often. Probably not a bad thing to do (don't fill it though, it would only need a dab)

I think Wreckah had a bent SOAS too, probably looked exactly the same on the inside.

The shaft was showing signs of wear. (All are click for big ones).


Here's a view of the bush


And an inside view. Notice the wall of the tube wearing too. If this hadn't bound up, it wouldn't have taken long for the end of the shaft to poke through.


Here's some wear in the other end of the tube. Notice the wall thickness.


A bit of wear on the shaft, shaft nut and more than half of the bush / (end stop?) is missing.


Another view


Here it is end on. (It used to be a hex nut on the end)


This is how it would have been sitting in the tube


It's a tough angle, lots of wear everywhere.

Steve's had 70,000~75,000km on his. :dowhat

I wonder how Paul Devir's was at 75K, he'd be pushing 130K now.

My has 56000 km and last year started to do a extrange noise on the rear suspension . I fix it just lubricate the SOAS rod.... So my could be algo on the dead way.

I'm waiting to recive a Traxxion rear spring so I'll disasamble the SOAS very soon. Good chance for a deeper inspection...but maybe it's time to go to " want to buy forum" and get one just in case. I have an Ohlins already so the bitubo it's not an option....

One has to say that how the bush / shaft guide is made is really the last crap. Mine wasn't nearly as bad but had too much play anyway. My suspension builder rebuilt a proper shaft guide with a much longer guide. A must for all the TLS Ohlins/Wilbers drivers.

I sent my SOAS down to New Zealand to replace one that had done just that too. Can't remember the miles the guy had but it is a common failure.

Steve, you should send it off to Suzuki and ask what they intend to do about it. :laugh

hmmmmm, here's me in the process of trying to decide which is best - hagon damper, which keeps the SOAS for £255 or Bitubo for £300 and eliminate the worry ..... :confused

As I went through the "braying Donkey" sound at the start of the year (cured with a lot of WD40), seems like the Bitubo is edging at present :O :confused

The bike must have handled like crap while it was wearing down the metal like that, no?
