Ohlins Monoshock RT Question

I am looking into the Ohlins BM941 rear shock on my '92 RT. Can someone that has experience fitting these advise about any bushings top and bottom that are needed.

I am placing an order to Motobins and would like to order the Bushings if I need them.

You will not need any bushings, they are provided with the rear shock.

You might have to find a suitable place for the nitrogen tank, it's a little bit tricky to install without interference with the side cases.

My experience exactly. I have the Integral (K-bike style) cases on my 1994 R100RT, I think installation is a little easier with the older Touring cases. The old thread here has pictures of my installation: http://www.advrider.com/forums/showthread.php?t=469568

Did you install it yourself?

Did you have to come up with any bushes?

I've seen your pix before and was wondering about the ends of your shocks. Looks like they use bushings.

How do you like the Ohlins?

Is the remote tank worth the upcharge?

They use a spherical bearing with aluminum spacers pressed into the spherical bearing with seals around them.

Thanx, I got sidetracked reading the thread about your ST. Wow! Nice job there!

Yes. SImple once I had worked out where the nitrogen cylinder woudl work best.

As noted elsewhere the Ohlins come complete with spherical type bushings. Simple unbolt old, bolt on new (once you have the remote reservoir sorted)

I am just a regular Joe in terms for riding and suspension set up skills, and the demand I make of my bikes’ suspension systems.

In practice, with the Ohlins 941 on my monolever 1994 R100RT I have come down to using three pairs of compression and rebound settings, depending on load. It seems that the compression damping adjustment allows for a little softer ride without getting too bouncy. Not sure that this makes the difference in price worthwhile.

I chose the Wilbers 640 for my paralever 1993 R100R. This has rebound dampening adjustment only. I opted for Wilbers to have something other than the Ohlins, and as this bike only ever gets one-up lightly loaded duty did not think that I would need the all-singing all-dancing adjustment of the more fully featured Wilbers models (or the Ohlins). No regrets about “cheapening out” here, but there again this bike is a much better handing/stopping bike than the monolever. With the latter as my benchmark my contentment with a less-featured rear suspension on the R100R may be more a reflection on the relative capabilities of each bike’s fundamental set up than a comment on the merits of the features of their different rear suspension components.

My guess is that 95% of us would be happy 95% of the time with a “simple” quality rebound-only solution. In situations such as this I am reminded of the statistic from driving safety that goes some like 95% of high school drivers consider themselves to rank in the top 5% of driving skills – I think that same characteristic is to be found in motorcycle riders of all ages generally, and certainly when it comes down to the nuances of suspension set up.

Interesting that you laid that out.

I talked to Ted Porter today and think the Wilbers 630 may be a better move for me.
