Hi Folks,
2006 Dynas can use a 180 60 17 tire. For most, the kit is not necessary; it is used to change the direction of travail of the rear turn signal wires under the fender. The same thing is accomplished with the installation of the turn signal relocation kit, IIRC about $28.00 or the the installation of a sissy bar kit. Do check the service manual, I believe the information is in there or possibly in the accessory catalog.
BTW, the bike will perform better with the stock tire and get better gas millage, or so I was told by the service manager, less weight.
Best to all,
