Wasnt sure if this is of any interest to anyone.....ive sent the Nitron R3 rear to Raceshocks [installed on my z1000]...it really was a bit of a punt as i was going to send it to Nitron but, nitron were about 220 ish for an R3 rebuild against raceshocks 165plus vat.. Its way over due for a sevice and, ive just got off the phone with them....yeah it needed it. Theyve replaced the bump stop with the new type that doesnt attract dirt. While ill be replacing some of the bolts myself with Ti ones they will be replacing any that are pressure sensitive with either Ti or stainless. Part of their service are strip down photos so you can see the state of the oil inside..etc etc... https://raceshocks.uk/ Strip down porn.... As part of the service the whole shock in component parts is put in a bath and cleaned multiple times also....ill put up some more pics when its rebuilt and, when i get it back....
Well, im not sure how to take that.... 1. Of course it'll be dyno'd - thats in their blurb. 2. Its not been serviced since new so no matter what the oil in there is shot.... Both obvious.
OK - Shock has been re-assembled and boxed back up - i should have it tomorrow apparently....244 quid all in (delivery back to me included)
Shock has arrived at home....so ive not seen the condition of it yet. Heres a dyno result from them...i did ask for a before and he said that they dont tend to do those unless theyre chasing a problem with a shock.
Ive never seen a dyno result from a shock before so ive no clue what im looking at..! (is that good)??
It's a force/peak velocity plot. It shows the adjusters are working and it's the one you'd use to compare 2 dampers or before and after. This one is a linear damper (other variations are digressive, progressive, blow off, position dependant, frequency dependant and probably a few others that I don't know) with roughly a 1/3 ratio bump to rebound. Pretty standard for an all-round damper on a motorbike. The more important plot to me is force/velocity because from that you can decipher the condition of a damper. How much hysteresis a damper has, if it functions properly and you get a good idea of friction too. One plot is better than none but I would want both plots before and after. They should be able to provide a force/velocity plot (also known as egg or potato plot) as it doesn't require another Dyno run. It's just a different way of compiling the data. It would have to be a plot for each of the runs they did. As a PDF they're not always very useful as they can get messy. They're best as a exel file or txt file. To sum it up, you have a damper with working adjusters. It is possible that it has issues but unlikely as most of them, but not all of them, would also show up on this plot. You want to stay away from the full stiff setting as that produces massive forces even at the lowest velocity. That's not uncommon but never a good thing. You'll never know if it had an issue before or if it was similar to what you have now.
Looks like new Well needed rebuild by the looks of it. I'm curious, do all suspension shops use a dyno? I've had my shock and forks rebuilt at two different suspension places, I never received a dyno graph for either of them.
No they don't. Especially forks as they need more specialist fixtures. Granted, forks aren't as critical for build errors as they self bleed, as a rule of thumb but when you're getting a "upgrade" you'd like to see the difference. At least I do.
