+1 :clapping:I wouldn't worry about replacing the lines on an '05 for a couple more years.
BUT, I would flush and replace the brake fluid every year, which is just good practice on any bike.
No need to replace lines yet...just replace the fluid.
My 2004 is going strong with no sign of any issues with the stock lines. My bud's 03 is the same way.
