Rear Shock Preload Adjuster

Does anyone know of a shock spring preload adjuster for the WR250?  I'm looking for one that will make it easy to change preload without dealing with the stock lock rings.  That could be a hydraulic adjuster, or one that has screw mechanism that's easy to adjust with socket.

I use my WRR as an adventure bike, so the weight I carry varies considerably with luggage.  Fooling around with the lock rings, especially on a trip where I'm not likely to carry a hammer/punch/shock ring wrench, is a pain.

I've never heard of anyone making a shock preload adjuster for the WRR.

Hyperpro used to make a complete shock for the WRR that could be ordered with a hydraulic adjuster, but it was rather expensive (about $1,000).

Ohlins could also custom make one, but that was even more expensive.

FWIW, I also use my WRR as an adventure bike, but I never find the need to adjust preload; I always set it for what really matters, the off-road portion where I don't carry any luggage.

50 lbs. of luggage directly over rear wheel changes sag pretty significantly, so it would be nice if one could adjust easily.

I just had my rear shock rebuilt by Go Race, so don't want to replace the shock.  BTW: You can still get Hyperpro shocks from EPM (https://epmperf.com/).  Their preload adjuster adds $229 to the shock price.  The Ohlins preload adjuster works well (I have one on a road bike), but their springs are different dimensions than the Eibach spring I have on my WRR.

I contacted the Xtrig importer in US (https://technicaltouchusa.com/) and they said their records show that the shock body for the WR250R matches the YZ450F, which they have  an adjuster for (https://technicaltouchusa.com/500010200501.html).  This MIGHT work, as there may be accessibility issues.  I ordered one and will report back on whether it fits the WRR asap.

50 pounds is a lot of weight!

Would be interesting to see whether the Xtrig works on the WRR.

I regularly ride weeks at a time on various off-road adventures (TAT, BDR's, CDR, PDR, etc.) with pretty wide ranging weather conditions.  I also often ride solo, so there's limited ability to share tools, spares, etc..  Yes, it's a lot of weight!  It's not uncommon for me to spend a few days in an area (e.g., Moab) to ride without all the baggage; hence my interest in the preload adjuster.

I'll post my experience with the Xtrig in the next week or 2.

Unfortunately, the Xtrig preload adjuster for the Yamaha YZ450F (#500010200501) does not fit the 2020 WRR rear shock.  

Technical Touch USA (the Xtrig importer) said they did not have another model that would work with the WRR shock.

Not a surprising result given that the shock in the WRR is made by a different manufacturer (Soqi) than the one in the YZ/WR line (KYB).

50 lbs will require a different spring, not an adjuster.
