I must be unlucky, bought a pair for my RM125B, they failed after a couple of rides, sent them back to Ikon (at my cost) they conceded there was a problem, rebuilt them and sent them back. Used a couple of times since, and they have failed again. One has lost damping and bottoms (locks up) after about 30mm travel (hit a hole in the track on the weekend and felt like I fractured my spine). Not going to waste my money sending them back again, have lost total faith in the product. Mate of mine bought a set, they leaked after first ride, they didn't want to know him. What a waste of money, cost me $700 and I am putting the 40 year old originals back on. Not happy.
