Sorry for the stupid question, but I found nothing when I did a search...what are the stock sizes of the XR650R wheels? I have an 01 that has wheels that are stamped DOT and a Front that is 1.60 and a Rear that is 2.15! :applause: Is this correct, and stock wheel sizes, seems small.

The front wheel is a 21" and the rear is an 18"

the #s 1.60 and 2.15 refer to the rim widths. Whatever tires you mount would have to be tires consistent with 21x1.60 in the front, and 18x2.15 in the rear.

21" 100-90 front.
18" 120/80 rear.

Not sure if that is stock. But thats what you should ask for when buying replacement tires...

We are running 80/100 to 100/100 X 21 (3.00 X 21) and 140/80 to 100 X 17 (5.60 X 17) on the rear..Of course you would use 140/80 to 100 X 18 (5.60 X 18) if you have an 18" rear rim.Your only concern is swing arm clearance. A 140/80 is a lower profile tire than a 140/100

If I remember correctly the ones that came stock on mine were 110/100 rear and 100/90 front. Not 100% sure on the front though.

Hey Guys, thanks for all the replys!! The reason I ask is I thought the wheels seemed kinda small (widths), I know it is 21 front and 18 rear. So, I had my local Moto guy order me up some tires and mount them, he gives me a great deal and I needed some next day as I am leaving tommorow for a week long camping/riding trip in the Sierra's!

He said he had kind of a bear getting them on, I had him install heavy duty tubes, so maybe that was part of it, but the tires sizes are...Front 80/100-21 and the rear is a 120/100-18 they are Dunlop 739's....are these going to be a problem, the rear seems like it should be on a wider rim...but dont people run the 140 Terra-flex on these stock wheels??? Sorry for the confusiuon!!
