brianjonesphoto Posted December 7, 2019 Report Share Posted December 7, 2019 Since it the only month our trials club takes off I’m diving into some much delayed maintenance. I pulled the rear end apart and serviced the linkage and swing arm bearings they are in good shape for being ignored for 3 years and don’t need replacing for now. I going to have my Showa shock serviced my a local suspension tuner with lots of dirt bike experience but this is his first trials shock. Upon external examination he is pretty confident it won’t be too different from a Showa dirtbike shock. I’m only having him service the shock with new seals and oil. It’s 15 years old and likely has never been serviced. One thing I cannot find a spec for is oil weight. He assumed it was either 5 or 10 and the rebound circuit should be a big clue. I’m assuming it’s either 5 or 2.5 as it’s a trials bike and needs to stay bouncy. Thanks Quote Link to comment Share on other sites More sharing options...
jonnyc21 Posted December 8, 2019 Report Share Posted December 8, 2019 (edited) I would expect it to be the same spec as the front forks "Showa SS05 (5w)" however I am not able to confirm this... If I find out for sure I will post the information. Edited December 8, 2019 by jonnyc21 Quote Link to comment Share on other sites More sharing options...

The Banyeres website lists Showa SS25 as the official rear suspension oil. It's 2.5W. But 2.5W rated oils can vary a fair amount. There are comparison tables online. Honda sells an SS-25 rear suspension oil under the Pro Honda name that may be the same stuff. 1 Quote Link to comment Share on other sites More sharing options...
