I looked but couldn't find an answer I have a 03 fat boy that I am putting 18" apes on how much longer cables and brake line do I need. Thanks

 

Best place to ask is the company that makes the bars. They should know how much over the stock length you will need. Or you can do it the old fashion way and measure the rise you have now, subtract that from the 18" and there's you starting point.

 

Are you going with internal wiring or not? That makes a slight difference too. I also agree with TheTroupe, if anyone knows what you need, the place where you got the bars from should know. The BEST way to go before you order them is to mount your bars then measure them yourself and see if that number also matches up with what that particular vendor has recommended to you. It's an expensive lesson to learn to be a single inch or less off.
