Just finished the installation of a Rekluse Radius CX autoclutch and a kickstart kit in my 2016 X-Trainer and had a chance to take it for a bit of a romp on Monday (Labor Day Holiday) at a friends farm. Got in some nice single track with a variety of terrain and obstacle types, along with some open field grass road race style track riding. What a great piece of kit... A bit like cheating in the woods. No performance loss in the open high speed stuff.
Fairly simple installation, my biggest issue was that I forgot to get coolant (the kickstart kit requires removal of the lower portion of the side cover, which required a coolant drain), and ended up having to wait an extra day to finish up the install until the bike shop was open so I could pick some up...
Well worth the upgrade for the tight and technical stuff.
