Hi, I have a 749S/999 Showa rear shock, on internet people change the shock and the spring. The spring rate is 75Nm, but this is for 80kg driver, my stock shock(S2R800) have a ration 100Nm but i have a problem because bike is waving in the corner. On the other side I found Ohlins technical that for a 55kg driver(thats my weight) is the spring with only a 58Nm. So I think that stock 749S with 75Nm gona be good and I hope that the bike be more stable in the corner.

You can't use spring weight recommendations for a SBK on a Monster. The linkage ratios are different. Use the recommendations for a Monster.

The valving is a different story. It may, or may not work for you.

You should also consider that te 749/999 shock has a stroke of 71 mm, whereas the Monster shock has a stroke of 66 mm. This might create a problem if you encounter a large bump; I don't know where the rear wheel might end up on full compression with the longer stroke shock.

I think this is the same shock i am using ...I have no issues with it at all

That being said I got it off a guy who was 200 lbs and he had it setup for his weight ...I am 220 so close enough

The only small problem is a very slight rub on the swing arm

OK, if it works, it works.

I'd still keep an eye on it, though ....

If you ever have the shock serviced, it's easy to have the stroke adjusted acc. to the Öhlins spec to the specific application.
