I have a 18 Enduro 120, I have 9 hours on the kit and one race so far. I have no other snowbike experience besides this kit and a ride on a buddies ARO 120. Full disclosure, I won my kit in a giveaway. I have 0 experience in the sport, but I do have considerable dirt experience.
Likes: the rear suspension is very good, progressive like a dirt bike, soaks up everything in its way, works fairly well everywhere. The kit handles well in fresh powder (8-12" with a base), carves well, feels very stable. Deep powder(24"+), floats better than expected. The whole kit performs very well in my opinion, based on the limited experience in the sport.
Dislikes: 2 hours ride time, every rivet in the rear of the tunnel had loosened up, causing a terrible rattling and vibration. Most of the bolts had loosened on the tunnel as well. I fixed the rivets by drilling them out and replacing the 8 rivets with grade 8 stainless bolts, stainless nordlocks and stainless nylocks. new rivets have been specd' for the tunnel, 1800lb test stainless vs the 260 lb al ones currently on the tunnel.
The ski tower failed to stay tight at the base, causing a "flat tire" feel to riding. I also added another brace to the rear lower of the tower in the wheel mount hole mimicking the one added to the front upper. Speaking of the ski, I feel it doesnt work well anywhere. The ski would track everywhere on the hard pack, almost like sand and too little tire presure. In the powder, it would sink, almost to fender level and wouldn't carve. I fixed most of the handling issues by lowereing rear preload 3/4", lowering the IDT 1", went 6 cicks softer on compression and rebound and 1 full turn out of fork spring(.6kg) pre-load. The rear shock(not the piggyback), I feel is valve a little fast. The valving is the same stack that is in the upgraded MT shock, pretty sure it needs to be looked at again.
5 hours in, chain adjuster bolts would not stay tight with out liberal amounts of blue lock tight. Track tensioner wouldn't hold the track in tension if there were any hard landing from jumps. Still haven't found a solution for the track tensioner issues.
9 hours on kit, was riding pretty well, the suspension changes had transformed the machine everywhere. The reduction in pre-load and rear ride height allowed the ski to float and ride better in the hardpack. Last issue to surface was the bushing connected to the motolink at the lower rear of the shock. I noticed some bushing material mushrooming out and galling between the mount and greasable link.
All in, mototrax customer service was pretty poor to start. Emails were answered days after sent, phone calls weren't answered. I ended up calling the dealer I won the kit from, whom I also purchased my bike from, explained the situation. Through my dealer, I was put in touch with one of the investors to explain the issues I am having. Since that call, my calls have been returned, fixes have been produced, parts to fix broken parts have come free of charge. Next race, I will see if the new parts and fixes clear up some of the issues. Overall, I am happy with the kit and the latest response from Mototrax. I feel thy might be on to something if the can keep the kit together and keep dealers and customers happy.
Full disclosure I had one last year...
