I put Heritage softail bars on mine . I did opt to swap cables so they'd look right. So about 10''. If your looking for comfort it's a whole different story and you need to get measured. The stock bars on my 07 were killing my wrists and back.
Brake and throttle. I replaced my clutch cable as well as there was a wear spot through the vinyl where it lay up on the crash bar. At least all the cable all look matched in finish, LOL. The irony there is when they removed the Y pipe cover to route the cable the tech found the pipe severely cracked which is how I ended up with true duels. My buddy went with adjustable HeliBars for his 09 and was able to keep all cables though they are a bit tight in appearance.
