We ran stock brakes on my husband's KTM 450 supermoto conversion and they had pretty good stopping power (good enough for frisky Appalachian riding on and off pavement). Our Husky 510 SMR had throw you over the handlebars stopping power with the oversized stock setup. As for tires, I liked the 150s best because there was less rubbing on the chain...Avon Distanzias were my personal favorite for 85/15 on/off road riding. Have you looked to see if you could find any SMR partouts on fleabay? The stock stuff from a Husky SMR should bolt right up. I'd like to get a SMR setup going on my TXC 250, but haven't gotten around to it yet.
