Was looking to put an:

Ohlins rear shock spring
PrtNo: 21040-36/105: (length)158.75mm, (OD)74.6, (ID) 52

Into my stock gen2 rear shock (getting it rebuilt as well). Below measurements are for an S1000R:

Oem (length)158mm, (OD)78, (ID)57

Btw, was lookin in the forum and couldnt find any info. What u think? Length looks fine outer and inner diameter not sure (~4-5mm diff).

For your awareness, I used to have a factory shock that had an Ohlins spring installed and it was re-valved by Catalyst Reactions in California.

I sold it on eBay not long ago. I can send you pictures if you want to see what it looked like. The pictures probably have the spring part number. I do not believe that it is the same spring as an Ohlins TTX spring. According to the picture below: 01091-36 was a 105N spring (for a big person)
