So I got the tires on yesterday. Just a note to anyone who might try the combo. Heidenau k60 and an arrow full exhaust on a first gen versys WILL have clearance issues! Normal riding is fine but when the suspension decompresses they will make contact. Nothing major but now there is about a 2~3 mm gouge in the right side of the block tread.:eek1 Just something to note. Other than that a tkc upfront with the heidenau in the back is great!
