easy there big guy...16's are junk. rims are expensive and not many good tires. i never even saw 15s. if you are dropping stupid money on rims and whatnot i would run 12s or 17s.
I would have to agree 100%. I run 2.5"x17" Front, 2.75"x17" Rear, with either Bridgestone super soft, or Dunlop soft 125 gp rubber. I have 16" wheels with cheng shin rubber for the rain.Having owned an xr100 with 12's and currently running one with 17's, I can safely say no to 12's. Impossible to get adequate cornering clearance! If money is not an object lace up some 17's. On a budget, use the 16 off an xr80.
