Thanks, good intel
Next question is, is the install fairly straight forward, you know for a regular guy (smarder den moi)? 
Install is very straightforward. Two bolts and bushings for each shock, and you'll want to have a means to support your frame and rear wheel when you remove each shock. Setup, though, has a bit of a learning curve, and varies by load and style of riding. I have mine dialed in right where I want them whether I'm two-up and loaded or just going back and forth to work solo. A bit firm back and forth to work and when riding solo, but still.................the ride cannot be any better.
Only PITA downside to Bitubos is the 36mm axle nut becomes a challenge to get on and off and/or tighten/loosen during rear wheel removal/installation/secondary drive adjustment. Reason is the Bitubo eyelet is much more stout than stock shocks, and will not allow most torque adapters to fit the axle nut. Unless you have a special tool made, proper torque on that nut cannot occur without removing the right muffler and using a 36mm socket. None of the marketable wrenches will fit................save for the one made by George's Garage, and I'm not so sure it will work either.
