Hi guys , just wondering I if any of you have done this Iv been playing with the idea of motarding my ttr for on road handeling an to Lower seat hight , but dont want to lose all the off road capability , so whrn looking around I found a couple of ideas , first was change the rims to a 19"-17" configuration which I supost to be good , also I read a couple of post that did a rear rim to front conversation 18"-18" on a xt , has anyone done ether of these , or a combo of both l 18"-17" ( I do like TW's OK) which Is where I'm leaning , this will probably b a was off if at all . also what's your thoughts on aluminum rims , durability , economy , performance. Any info would be greatly appreciated
