I have been thinking about making a track type system for my 2002 Husqvarna cr250 with similar ideas to the snoxcycle/all other brands i was thinking about cutting a snowmobile track, youth snowmobile track, but the best idea i have had i think is to take a old off road truck tire cut the sidewalls stud and/or mount angle iron in cross sections i have worked out all the kinks in my mind like keeping the track taught but i cant figure out how to drive the tire cause i was picturing it internally driven(inside of the tire where the tube was) only thing i could come up with was somehow make ridges or take about 10 30-40 tooth sprockets putting spacers between them then tight the track very tight so the sprockets grab the rubber but i would think it would eat away at the rubber to fast          any help would be appreciated thanks

2" dia wood dowels sliced in 2 pieces, bolted to the tire case.
fabricate sprockets to fit the dowels..
or...
buy a snow-mobile

Use a youth snomobile track and drive sprockets that fit the windows / cleats. Hope it holds up to the weight/power/shock loading of a dirt bike.

Or just save your pennies and buy one of the many track systems on the market for motorcycles.

I can't see the truck tread idea working. How would you keep it aligned? Would you use a bogie wheel setup, or slides? How would the slides be lubed? Would the carcass really be flexible enough to perform as a track? Plus, like you said, how do you reliably drive it?

There's a ton more things, like allowing the track to articulate to keep from putting too much stress on mounting components. Figuring out a braking setup. How to shape the track system (both fore-and-aft and side-to-side) to allow for a good compromise of traction, handling, and floatation.

Better off to just buy an existing system. Unless you have the skills and equipment like the guy that built the Fatcat CRF450R(see thread in this forum), you'll end up giving yourself a lot of frustration. You'll also need some understanding of engineering principles to make this work.

Thanks 3BeeJay3! I'm the guy that built the Fatcat

I popped into this thread to learn a little about snow bikes, especially a home built version.  I'll need a project this winter after all

cool project! i'd love to see it
