I'm trying to set up my ttr125 le for supermoto on the cheap...I have bar end sliders installed, peg sliders made from hard skateboard wheels with 4 holes drilled in them and attached to pegs with 4 zip ties(may go with saftey wire) only way I could figure how to attach as there's no cross bar in pegs...can I mount a skateboard wheel to swingarm by drilling just ahead of axel and bolting straight thru? Will it weaken the swingarm..cant think of a way for front except to tap axels front and back but I've never done it..Where to mount catch can? as I have a battery and it's tight under there.....Last question, What's a good tire for stock rims? BT 45's..Kenda k671's? and what size..19"ft and 16"r ?
