After a bit of searching, I have found the Ohlins TTX36 rear shock absorber with the hydraulic pre load adjuster that I want - a DU931 - at a price I'm prepared to pay. During my search, I read a write up comparing the Ducati OE Ohlins TTXR, the Ohlins DU788 and the later DU931 TX36 MkII and one contributor talked about spring rates being affected by a progressive or flate rate link. Is there a flate rate alternative to the standard progressive on the 1098R and if there is, how will that affect the spring rate I choose ? Thanks, Andy
There are a few companies (Dan Kyle, Moto Corse, Bursi etc) that supply either the one or two position flatter rockers (copies of the Corse rockers), and they normally necessitate the spring rate going up a couple of positions (some recommend going up in 5Nm increments). It's not too dissimilar to the 749R rockers and the higher spring rate on the 749R shock. But there's also Forsaken Motorsports rocker which claims to have no need for any spring rate adjustment.
So that begs the question what is the difference between progressive and flat rate and is it a road or track thing ? Andy
Given the last set of photographs taken at Almeria, the stomp grip is clearly stuck to my arse, so no. Andy
Andy, Not sure why you are so set on getting a shock with a hydraulic preload adjuster? Preload is only adjusted when setting the sag on the shock. Once it is set, it generally remains the same (yes, I know that chain adjustment using an eccentric cam means it may need to be reset), so if you have a good C spanner, you can easily readjust it if you want. It's not as if you are carrying a pillion on your R so I am at a loss as to why you need hydraulic assistance! Just sayin' like....
It isn't just the hydraulic adjuster. I have first hand experience of the difference between a rear shock absorber made by Ohlins for Ducati and the equivalent one sold by them. Okay it's not chalk and cheese or day and night but definitely an improvement. The hydraulic adjuster is a great addition which does make the set up so much less of a faf and makes a minor adjustment for the track so much easier. And I've got money burning a hole in my pocket and I want one . Andy
That's fine then. I have heard that the Ohlins stuff that is not made for Ducati is of better quality so that in itself is a good enough reason for me. Cool.
Same subject and topic but slightly different question. Looking through the owner's handbook I thought I'd look at the rear suspension set up and the picture and words in the handbook look nothing like the suspension unit on the bike. I have a gold and a black adjuster at the top of the shock and both have writing on them but my close vision after the cataract surgery is so bad I can't decipher them. Can someone tell me which one is which and what the stock setting is ? Thanks, Andy
Black: rebound standard setting -14 Gold: compression standard setting -14 Both measurements are anti-clockwise clicks from fully closed (clockwise). Taken from the workshop manual which does show the correct TTX shock.
