V4S fork and shock service

Has anyone performed the service on the front fork tubes and the rear shock ? I have 8500 miles on mine and they are not working well anymore . I know I need new oil and was wondering what everyone has used . I see the owners manual calls for shell donax AT fork oil . I’m not sure if anyone has changed anything and found better suspension results . I.E fork oil weight , rear shock spring Ect

I had mine dialed in for my weight etc when I bought it. Makes a huge difference.... have a suspension tech take a look
For Service, when the bridge get there, I’m sending it back to Öhlins. Yes, you can set your sag with a buddy too...that would help. Make sure to buy tools for rear shock. I bought it directly from Öhlins, if you’re in California, Kyle racing has them too.
Dave Moss recommends changing the stock 5W fork oil to 10W, as the front is way too soft relative to the super-hard rear. I've done that and the bike feels quite a bit more balanced, front and rear. The fork oil change is apparently a real lot of work on this bike, it cost me about $500 AUD

+1 to Dave Moss. I finally have started tracking my 2019 V4S. Its a wonderful machine. I've been riding for 30 years but just started getting into track the last few years. Been learning with the California Superbike school on their S1000RR'S. I was excited to track my V4S, and it went well as a tall guy (6ft) and a heavier chap (190 pounds) is fits me well. BUT, there are definitely issues with the front end compared to the BMW. I have spent time with Dave Moss (the tuning guru here in the US) and he agrees, as do others. So, I've moved away from dynamic suspension settings, and now have fixed setting in the DES menu. Dave gave me some great advice and helped me dial in those DES settings. Moved to fixed with his settings makes a huge different. Of course I still needed to manually click the sag etc into place for my weight, but wow, its so much better. The next thing that Dave has suggested is upgrading the suspension valves, and for oil. I plan to do that over the winter to get ready for track season. Am I the only one? Keen to hear thoughts. I can share a video of my settings too if folks want. Its not high production quality though

I did the same. I also upgraded the front end fork. Then Dave Moss helped me dial in.

Ok thx slot man... last year I I was 2:30 but I had an accident and broke my clavicle and three ribs so I was laid up for a while and gained a bunch of weight I'm sure I'll be back down to 2:30 or 2:40 this summer I live in Massachusetts United States

Ugh. Sorry to hear that mate. I’ve been there. I’m 200 now, but was 230 when I had my fork work done. Lost weight now, so need to adjust again. Are you tracking it? I only ride mine on the track

Where are you? You really need an Ohlins tech
And what was your experience?

Rgds, Filip
