On my KZ 750 LTD it looks like the bars reach back 2 to 3 inches behind the gas tank filler cap and the brake lever is actually 4 to 5 inches behind the front forks. On your KZ 650 with the Flanders bars it looks like your bars reach back to the gas filler cap (or maybe just a bit beyond) and your brake levers are just about even with the front forks. That's a pretty big difference.
