The Oem Bars are a great fit. and very solid....
My only worry, is repeated fitment, but in use they are great...
I missed out on 3-4 sets in a week on ebay for 50-60 notes due to work so ended up paying over the odds on a pir really, but they were brand new with 4 keys etc from aewilcox ebay and they just do the job
3 sets of thule 591's and jobs a good'un for the bikes....
