Title: Replacement Shock
Post by: Andrew2 on October 24, 2017, 06:10:04 AM
  The dealer I'm buying my '87 K100RS off has replaced my original seized shock with this one. Does anyone have any idea what it off or brand name?. I haven't seen it yet in person. He just sent me a photo and said it was an upgrade :dunno .

You can read the post entitled “works performance closed permanently “ that I started . There are a few posts with good info and you might be able to see pictures of what is available for K-bikes. In your case, make sure that there are no clearance issues with the extra reservoir, including the side case.

 Thanks Alex,
   I searched all of those mentioned in that thread but couldn't match any of them to the shock they've put on my bike in the above photo. The curiosity is killing me. Maybe someone will know what brand it is eventually lol.

It has a lovely freckled patina on its frame mounts that also encompasses the Art Deco fluting of its gas chamber. It looks like the work of Schmidt Hofer, or one of his protégés. If that isn't an upgrade, I'd like to know what is. It doesn't need markings; it needs a pedestal.

Looks like it might be a White Power Shock (talk about politically incorrect!)  Not sure if they ever had one for K bikes, mostly offroad motocross that kind of stuff.

I went to the shop and checked it out today and there's not an identifying mark anywhere on it. Here's another couple of photos.

  It seems to have compression and rebound adjustment.

  Nice find Chaos. I think you have a winner there :clap: . You guys are great :2thumbup: . Looks like the only difference is mine doesn't have a Schroeder valve on the bottom of the reservoir. Other than that it looks identical. Any clues on the numbers on the spring?. I'm guessing 220mm spring length and the 40 must be something to do with the spring tension.

So long as you like the way it rides....my Progressive shock ain't worth much. But I don't hate it enough to replace it.
Title: Re: Replacement Shock
Post by: Andrew2 on October 26, 2017, 08:45:40 AM
  I'll find out soon enough. If not I have access to a brand new never used standard shock.....at a price.

  I just got offered a brand new,unused original K100 shock for $250AU. Think I might buy it as a spare. Are the K100RS,K100RT shock absorbers all the same or do they differ in some way?.

The shocks for the K100 RS 16v are longer than the those of the 2v so that is probably true of all the paralever bikes but i am not 100% sure.
Title: Re: Replacement Shock
Post by: Andrew2 on October 27, 2017, 05:27:36 PM
  Cheers Filmcamera. The one offered to me came off a 2v I'm just not sure whether it was an RS or an RT.

The way I check part compatibility is to go to a BMW parts fiche like this one (http://www.maxbmwmotorcycles.com/fiche/PartsFiche.aspx). Select the bike I have, find the part and write down the part number. Select the bike that contained the prospective part and look up its number. If the two part numbers are identical, the part will fit my bike.

Shocks from RT and RS 2v bikes have identical part numbers so should be interchangeable on the bikes.

  I finally took delivery of her today so I'm officially a K100RS owner 30 years after my first ride on one :clap: .


(https://i.imgur.com/lNjwRDL.jpg)


  It took a week to fix the odometer which wasn't working and 28.1 kms from the shop it stopped again :bang-head:  so they're sending me another one. You can see this time the trip meter knob has tried to escape from the speedo housing :hehehe so I'm guessing when they fixed it it wasn't put back together correctly.


(https://i.imgur.com/nU5bwVr.jpg)


 When the new one gets here I'll pull the original one apart and see if I can fix it as they have just put all new cogs in it. According to the last registration papers the kms are genuine ( 33,900 kms ) so I would like to keep that on on the bike. If I remember I'll take photos when I do it and post them up.

  I just discovered something interesting on my "new" rear tyre that was supplied with the bike.
(https://i.imgur.com/U6ld5Vu.jpg)

  It's a Michelin Macadam 50 which I believe hasn't been produced in over 10 years. If I'm reading it right this is an 11 years old " new" tyre they've put on.

I had two of those on my Brick twenty years ago, and hated them. They were unpredictable every so often the back end would break away on different corners. A mate tried the bike and had the same problem, and told me to get Avons. Once I changed tyres the problem went, I am now back on Michelin Pilots and like them. No way known would I be riding on the tyres they have supplied, probably old stock they got cheap.
Regards Martin.

It's coming straight off. Goodness knows where they found an 11 year old tyre from. The weird part is I had just taking it for a fairly hard ride up MacQuarie Pass ( my local tight mountain twistie road ) and it went well. I won't be pushing my luck again though. Luckily the front is a Pirelli Sport Demon that's up to date so I'll get a match for that.
