| The question is whether aftermarket lines are a significant improvement over Ducati’s OEM lines - and enough of an improvement to warrant the cost. If better stopping power is your goal, the answer is no. If better lever feel is your objective, the answer is maybe, but probably not.
The only reason to replace the OEM lines with aftermarket lines is to try to improve the feel of the brakes at the lever. If a hydraulic line is allowed to expand and stretch, you get a spongy feel at the lever just, like when you have air in the line, but not as severe. In other words you loose the direct relationship between the force that you apply to the lever and the force that is applied to the caliper.
Do stock Ducati lines stretch and expand much different than the aftermarket lines?
No.
It’s exactly the same effect that you would get if you placed a stiff spring in series between the lever and caliper pistons. When you pull the lever the spring compresses a little before the force is applied to the brakes. It’s a feeling that you accommodate to quickly when you ride an unfamiliar bike. In a panic stop it’s actually a beneficial characteristic that helps you to avoid accidentally locking your brakes.  |
