I am considering installing the "new" HD touring pull back handle bar kit (part #55914-98). It recommends new clutch cable, brake line kit, and throttle/idle cables. The bars supposedly come back 2" from stock. Has anyone done this and know if you really need all the new cables or if there is enough play in any of the existing cables to retain them?

 

I installed those (the first time) without using different cables.
I didnt like the angle they put your wrists, too twisted. That is to say your thumbs point too forward, not comfortable. But some people must like em so...
I ended up installing Kromeworks Sweepers. And used a longer clutch cable. p/n 38649-08

 

I am going to be installing the Khrome Werks Sweepers +2 PN 300515 on a 08 SG. A longer clutch cable is needed, unless you want to route it outside of the fairing. Looking at the stock clutch cable, it is already very snug. I ordered a +4" clutch cable PN 38624-08. The stock non-abs brake line should work but may need a slight bend put into it. Some have said the stock throttle cables will work but tend to bind when the bars are turned all the way. So it's a good idea to go with longer throttle cables.
