I did a custom 8" stroke offroad valved rear Elka for my buddies Versys.
3 Way loaded reservoir and hydraulic preload and adjustable ride height on the bottom clevis.
No issues and phenomenal off road valving!
I wish I would have got that over the Hyperpro which is valved more for street riding.
In 2 years and plenty of off road pounding he has had no issues with the Elka rear shock.
Oh and it is so beautifully made as well!
