Hey guys, I no longer have my banshee but do have a question on some tires im looking at buying. I am looking at the maxxis razr tires for my yfz. I am now riding my stockers which are 20". I am looking at both the 18 and 20 inch models. I ride mostly trails and little mx. What would be the advantage of 1 over another? What size should i go with? Thanks for your input.
