I am having a hard time getting ahold of Timbersled to ask this question. I am looking at buying a used 2016 with TSS and fit kit for a ktm (not sure model). I will be putting this on a 2012 kx450f. Does the TSS shock fit standard. Do I just need to buy a basic $300 fit kit for a kawi then or what. Also what would I be losing the air filter that comes with the TSS kit?
