The twin-shock set-up is all new, a request made while I was on tour down in South America on u'Hack 2.0 and the "catastrophic" shock failure I experenced. Jay was in the middle of building the chassis and rigging for U'Hack 3.0, set what they had done aside, and built a new sub-chassis and trailing arm for the tub with dual Progressive shocks mounted in tandem (one fore, one aft). My thinking is, each shock should only have to "work" half as hard, and, should one fail, there is still one out there working, double-redundancy (though, in this case, only half the spring rate).

Even with this set-up, I'll still always carry one spare shock with a heavy spring installed, so worst case, should both the twin shocks fail, I can install the single spare with a heavier spring rate and carry on.

I may seem to be goving overboard with this whole shock thing, but I have had a Progressive shock failure on every long-haul tour I've taken so far.

I have very limited room and cannot have any of the shocks with pre-loader handles.
Can you reply with the exact order/model number of the HyperPro's that you've ordered for the bike? I might be willing to given them a try. I've seen too many failures with the Ohlins, WP and Fox Shocks. So far, the OEM shocks that BMW installs on the line have been the most reliable, but the spring rate is really too soft.
