Mojo SL rider here:
really really sweet bike, fast as anything, my fairly normal build is about 26lbs without trying too hard and has been ragged all over the uk and alps. Have run it with both 140mm front and 160mm and both are great, more of an xc bike with 140, more of a hooligan with 160mm (obviously!)
Mud clearance is ‘not brilliant’ once you have a good bit of chainstay protection going on and 2.35 highrollers (which are quite small really) however never actually been a problem for me. Could do a pic if you really want?
the only other comment id make is how heavier are you and how agressive are you? I am only 10.5 st but a pretty aggressive DH’er I do notice some very minor flex. if you are heavier than me and still corner hard you might be better off with something stiffer (maybe the SL-r?). (this is compared to a turner 5 spot for instance which i couldnt budge but the frame weight saving is massive!)
