I ordered with 15mm height adjustment and after about 20 000km the preload hose broke. I think it was a bit too short for that and stressed too much. They made me a bit longer hose in factory. I also have 100Nm spring insteadt of original 80Nm. They can also adjust manually preload area for hydraulic screw, but the spring has to be off then. Mine has now 100Nm spring and that manual preload is also tightened about 5mm. Also when they changed the hose, they made full service for the schock with oil change and seals etc. I also asked to take away that useless toolbox and it is now super easy to adjust rebound. Now the schock is perfect from solo ride to two up and luggages full. Original schock was really the worst i have had in any bike in this millenium.

One connector had to be fixed away from toolbox.

That actually looks pretty good without the side panel. My shock has a red anodized adjuster that would show. And be easy to use as well. Hmm, food for thought

@eka I think you have made a great solution.

So, just to be clear in my understanding...... You specified a 'slightly longer' shock assembly to raise the rear of the bike up by 15mm ?
.......or specified a 15mm longer shock assembly ?

The height adjustment is at top end. You have to ask for it at order. I have it adjusted as long as possible. The screw itself adjust maybe that +/- 5mm, but as in swingarm the fixing point is much closer to swingarm fixing point, it moves maybe that +/- 15 mm at wheel end. I wanted suspension to higher to scrape pegs less. Front telescopes are moved as long as possible, so tiny rise there too. I also have at front wilbers progressive low friction springs. Those actually bottomed easier than originals, so i get changed there 5mm longer preload tubes to make it stronger. Original front is not so bad though. Adjustment is quite poor, but it is good now. I have not touched for long time, but i think rebound is pretty open and compress pretty close now.
