Just to kick this thread back from the dead, I installed some Fren Tubo lines from PJ
PJ's Parts - Accessories For Every Bike And Rider and what a HUGE difference it makes in braking feel. I felt from the beginning that the bike's brakes were lacking. Spongy feel, not really up to the standard I'd expected. Changing out the brake lines (front and rear) made all the difference. After changing the lines and using a high quality silicon brake fluid the brakes are transformed. No more much in the controls. When I squeeze two finger fulls of brake I get a firm, consistent feel with lots of feedback and the bike stops right freaking now.
Not a particularly flashy mod and nobody's going to be hanging on your elbow at the local watering hole in amazement at your hot zoot brake lines. Women, or men for that matter, won't be hurling themselves at your feet, swooning with unrequited lust at the glory of those tubey things hanging out of your calipers. But by Zeus you'll have a bike that'll stop like it was supposed to and that will give you consistent feel and fine control like it should have had from the factory.
