“bulletproofing” a 570

I bought a 570 back in may and have really enjoyed it! but my main concern is what should i be concerned of and be ready for. i hear that the stock axles are a little weak when you upgrade tires etc…. id like to bulletproof mine and save the trouble. already looking into Rhino axles because i plan on putting mayhem tires or something similar in the new year. Also, i store my atv in a enclosed barn, ive opened my airbox to find loads of nests, any tips to keep the mice away? Thanks in advance :D:hand:
