Can I use this suspension?
« on: July 30, 2014, 01:26:13 PM »
The suspension on my 1992 k75rt, began to look worn out, and the dust cap had come off.  Can I use this bmw SHOWA B0272 suspension ( believe it coming from r1150rt) that I have?
It seems brand new. 

Thank you

Do the mount bolts/studs fit through the eyes?

Is it of a suitable length to give you an acceptable ride height?

If those two are yes, stick it on and go for a little ride...

If you like it, or at least can adjust it how you like it, then use it - after all, it's a spring around a damper - it doesn't know if it's on the 'correct' bike...

That depends on the model. They wouldn't rebuild my 420 and the bladder and internal parts are no longer in production with no new parts entering the pipeline. Less expensive Progressives such as the 412 aren't rebuildable at all.

I was quoted that the 420 was rebuildable until I sent it out to be rebuilt and 3 weeks later received rod that parts were not available. So -- I am skeptical about progressive rebuildability claims.

The Showa my my K1100RS is not rebuild-able.  Give Terry at RaceTech a call about rebuilding shocks.

Hmmmm...Gerrad Capley of Progressive said my 412 can be rebuilt...I have that message in my email (I just haven't gotten around to obtaining a loaner shock and sending mine in). It is quite possible that I contacted someone there that doesn't know what they're talking about, but I did tell them it's a 412 on a K75  :falldown:

Progressive customers service is one of the reasons i will never buy another Progressive shock. if you get lucky and include a copy if the mail when you send it in, they'll send you a brand new one for your hundred bucks. If not, they'll send it back and say, 'Oops'.

Maybe call Progressive and ask for confirmation. The rep I talked to confirmed that the 412 was not rebuildable and the 420 was but that no parts were available so it effectively was landfill.
