I have had the camso TS4? tracks for almost 3 years now. I run them on a honda foreman 500. I have power steering and it works great. I am able to pull my 8x12 skid house around and do anything else in the snow.
As mentioned, don't expect to be going very fast with them. I haven't had my spedometer adjusted, so I don't know what my top speed unloaded is with them, probably in between 20-25mph.
Like SDMF mentioned, after the initial install, it takes about 45 minutes to install them and 30 or less minutes to switch back to tires.
I've pulled the portable over 36+" of snow and haven't gotten stuck. There are 2 negatives to the tracks. 1- they throw up a lot of snow, the under carriage of your atv will get pack with snow and ice, it helps to clean it out or park it inside a heated building after use. 2- they will make your machine work harder. I think my MPG goes down 50% or more with the tracks.
