Quick questions (for Urban GS): Would a rise of 30mm for the 640 require a change of side stand? What are the options for main stand with such set up? Thx.

Park your rear wheel on a 30mm plank of wood and lean it on the side stand. That’ll show you how it looks.
All the centre stands I’ve seen advertised state clearly ‘ for standard height suspension only’ I believe this is as much for silencer clearance as anything.

Looking to upgrade the rear shock to Wilbers on my 2020 Pure. I see that it increases the height by 30mm. Bike is perfect height for me. Should I order with height adjustment to compensate for the longer shock?

I weigh about 75kg with gear on. Rear tire pressure is set to 42 psi and bike feels like riding a shockless cart going over bumps and expansion joints.

Took it to a suspension specialist this weekend. He checked the sag and felt the stock setting didn’t have enough preload - contrary to what I thought was needed. Ended up increasing the preload and adjusted rebound damping slightly. TBH no noticeable difference.
Leaning towards 642 with Mechanical XP-A option so I could make adjustments later and doing it DIY with help from this forum.
Alternatively I could order the fork cartridge kit together and get someone else do it for me but then I miss the fun of getting my hands dirty.
Advice?

PS - tuner hadn’t heard of Wilbers which was a bit of a surprise. He recommended Ohlins but I’m really looking for a more comfort/ road ride experience. Haven’t seen the option of ordering the Ohlins kit to customize to my style or how to order the springs to go with it. Maybe that’s all left to the dealer?

@shaneturban called them and the gentleman suggested I go with TFX and with valid reasons. But now I’m more confused. 🤔.
Just assuming the cost of a rear shock with adjustable preload, adjustable high / low speed compression and damping - what’s the cheapest option - Ohlins, TFX, Wilbers?

To confuse you even more I have a Penske 8900 shock. $765 It has one knob that controls both compression and rebound. You can add later hi speed/remote reservoir to the 8900 if you want more adjustability. I had them make the shock 1" taller then stock. 8900 Emulsion Single Adjustable - Penske Racing Shocks

@shaneturban Thx. I’m figuring go with my gut and what my wallet can afford but anything will be better than stock.
I’m going to try DIY so I’ll start with the rear shock only I think.

I finally pulled the trigger and bought a 70mm Wilbers Kit for my Urban GS .... Its second hand (2000km old) from a fellow rider in Hungary and hopefully gets here in 5 days. (fingers crossed, its a long way to Australia haha) Now as far as I can tell it doesn't come with installation instructions... I am not worried about the shock, but I have never installed cartridges or longer stanchions on a fork...... I have been trying to find any info online but so far I found 0 ...... Has anyone got the instructions or a link to a download? Or maybe a youtube video? (I found some videos about modifying USD forks but nothing about conventional (I assume there is a big difference on the inside?)
Also, what grade fork oil is everyone using? I am 85kg with gear (springs are for my weight) just not sure about the correct oil?
Any tips would be appreciated, cheers guys.

When I install it I will take a few pics and write up a simple how to manual ......
