Off a 2007 DL650........both measure way above the min thickness of 4.5mm. I checked Ebay, lowest price I saw there was $46 for one, shipped. If you have many, many miles on your Strom, you might want to check the thickness of your existing disc's to make sure they are within spec?? Price is $55 shipped for the pair, Lower USA. Paypal Gift (or add the 3%) or personal check works too. If you want the rotor bolts, add $5.
