Good day to you all My 675R has now done 21k miles and although I have maintained her religiously with the basics I've failed to give much attention to the suspension. I'm now considering whether I could attempt a service on the forks and shock. I've done a quick search on the forum and didn't come across any "How To" on this. Questions: 1. Is it something a DIYer can or should attempt (I have a wide selection of tools built up over the years and am fairly proficient for the basics) or should I remove them and take them to a specialist? 2. Are there any specialist tools required? 3. Can anyone point me to a guide on how to go about each of these? Thank you all in advance and look forward to hearing your thoughts on this.
I'm considering the same as you over winter. I don't think there's much you can do yourself with the rear shock as nitrogen is pumped into it. Disclaimer- I'm often wrong! If you Google it, various places will rebuild and recharge your rear shock. I think you should be able to do your forks yourself though. If you have/get the workshop manual there seems to be a pretty good guide.

https://www.brooksuspension.co.uk/triumph-daytona-675-shock-absorber-rebuild-repair-service/ The shock absorber repair service includes - • Disassembly of shock absorber • Inspection of all parts for wear or damage. • Inspection of piston rod for straightness and polish • Strip and thorough clean of piston assemblies, clean and flatten pistons • Replace all oil seals, dust seals, o-rings and bushes • Rebuild shock absorber with high quality Motul Factory Line fork oil • Charge with Nitrogen
Will have a look at doing the forks m'self then and getting the rear-shock over to my Bradford brethren !!! https://www.brooksuspension.co.uk/triumph-daytona-675-shock-absorber-rebuild-repair-service/
Let us know what they say and how you get on. I'm undecided whether to get the rear shock serviced or put the money towards upgrading to a different shock.
Probably K-tech as I'd like their fork internals too so everything matches but all of a sudden things get pretty expensive so I go back to thinking about just servicing the forks myself.
Was just looking at the price of those and phew! Maybe if I think about saving the £160 on the service and selling the shock (no idea what I'd get for it) and add a "little" extra !!! lol
Only problem is then you'd have no standard shock if you wanted to put the bike back to standard to sell.
Mines a similar mileage and considering doing the forks myself as well, oil seals/dust seals and fresh oil, although I'm not sure I ride it enough, or hard enough, to justify it at the moment. Watched a video on youtube and apart from some sort of headstock stand (which would be the biggest expense) I would only need a pin wrench for the top cap, everything else is doable with standard tools.
This is the video I was going to follow, if I tackle it, makes it look relatively easy <iframe width="560" height="315" src="" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
It is certainly possible to service suspension yourself. I think it is worth bearing in mind that the limitation for us home mechanics is almost always in diagnostics. I.e. yes you can strip the parts and change seals/oil but will you inspect and measure the shim stack? can you tell if they are beginning to warp? that's where a decent pro earns his salt IMHO
You can do the rear yourself and refill with air via a mountain bike shock pump then take it to your local garage and ask them to charge it with nitrogen for you. Most should only charge you min service charge, £20 or so (personally I do as mentioned above and do my forks myself and get the rear done by a pro)
Hi All Having a really interesting time with my forks! I drained, cleaned and filled my compression side with 135mm air gap WITH the spacer in place. Purged the air and put the fork back together. Q1: I cannot compress the fork past halfway, I understand that the fork should compress without bottoming out. This is off the bike, between my legs and pushing down on the fork whilst stood above it. I weigh 75Kg and I'm being forceful, but not as much movement as is suggested in videos on YouTube. Any advice? Now the rebound side is puzzling me. I've done the exact same procedure as the compression side. Filled oil (I've put in about 550ml of oil) past the air gap I want and started to purge the air, by pulling and pushing the damping tube. I'm hearing gurgling and when I pull up the damping tube I get a splurting of oil out of it. There is no valve spring, needle valve, spring spacer or spring in the fork at the moment. Q2: Any ideas on what I'm doing wrong with this side (Rebound)? Thank you, thank you and thank you for any and all guidance you can offer me. I'm not yet climbing up the walls in frustration, but not far from it!
Quick update : I used a rod pull up tool to pump the oil about and then got the spring, valve and damper rod in. It seemed to work and put the forks back together. Rides amazing.
Glad its all sorted and didn't turn into one of those jobs you wish you hadn't started Still haven't got around to the seals & oil on my forks yet, the very tiny weep from the seals only seems to happen when the bike is stored for long periods, it goes away after a few rides. I know the oil is probably a bit old and tired, but then so is the rider
