Have anyone tried the new explorer from AD Boivin on your WR? http://www.adboivin.com/Manufacturing.aspx?page=500&langue=en&modeAffichage=0&Approb=1 I was wondering if the WR have enough power for it to still be fun? They recommend to gear down and what does it to the topspeed. It would be fun to hear about it from someone that have tested it. 2Moto also have a bolt on track. http://www.2moto.com/ Anyone tried this one. Here they ride it on water too. http://nz.youtube.com/watch?v=lvNEWygne8s If power is enough I'm leaning more towards the AD Boivin because of the ability to move track forward and back depending on snowtype. It's also easier to bolt on because it uses the bikes own damping and svingarm. One more plus for the explorer is that it does'nt need snow to lube the sliders because it has a wheelconstruction instead of slides. So this can actually be used in wetlands, sand and other demanding enviroments where it's otherwise big problems.
