13 KX450 on a 16 Timbersled LT 137". 2 1/2" tapered track. Has all the goodies and is set up right as a snowbike. Has an engine shroud (a must in deeper snow, I have a 2nd one that has complete coverage even over the pipe)Thermobob thermostat, Digital engine thermometer, hand warmers, hand guard, rear hand brake, air box removed with a airpod, block heater, oversized 2.7 Gallon fuel tank with a spare 3.3 tank that comes with it. Will go all day with that. Triple skags on the ski that works very good, much better than some of the earlier models. Ice Scratchers on the ski. The air forks on the bike work great because you can pump them up and make them hard enough for what a snowbike needs but just lower the pressure if you want to use the bike in dirt. Regular settings aren't nearly stiff enough in the front for snow. I bought the kit new March of 16 and rode twice then did 17 & 18 season. I have left it a dedicated snow bike since I put the kit on. Bike and kit are both in great shape and ready to go. Please call or text 208.251.7217
