I have an 2015 Outlander L 450 and I want to make it wider. The stock wheels seem really skinny and unstable when riding off camber trails. This thing is pretty easy to roll compared to my other quad with 27/12/12 tires.

I have heard wheel spacers are effective but pretty unsafe. I would get new rims and tires but I’m not sure what a good offset would be.

What would be the best way to make my machine more stable?
