I don't think that statement is wrong, but it's innacurate. With Ohlins the harder you ride, the suspension doesn't get better... it stays consistant, which is good.
BMW suspension, even brand new, starts to get worse as you push it harder, because heat and the buildup of air bubbles in the shock oil (cavitation) cause performance failure.
So it's not that Ohlins gets better, it just stays consistant and doesn't fail when pushed hard.
No, thats not what Wilbers do. They don't remove your ESA gubbins at all. They don't replace the shock either. They don't service the shock or change any internal components.
What they do is change the Spring to a Wilbers spring weighted to your specification, then fit a new Compression chamber which is adjustable, and put a Wilbers sticker on your existing shock and hand it back to you. So if your shock was fooked when you gave it to them.... it'll still be fooked when they give it back to you. As only the spring was changed.
Only on pre-2013 bikes did they change the shocks.... not on the newer bikes.
TOURATECH (tractive) EXTREME shocks....
Now they use their own Stepper Motors, with larger diameter rod, their own shock with internals, and fully serviceable, no compression adjustment, new spring weighted to your specification, and anti-cavitation technology plus heavy bump stops. Fully ESA compatible, so a very good replacement option.
I don't think Touratech use any of the original parts....
But its expensive.
