Still not convinced. Because this still tells me it's 100% rider error and not due to the brake lines. You just don't grab a fist full of front brake on a sport bike. This is one of my gripes with the MSF classes. They tell you to use all four fingers on the brake lever. When with sport bikes you should only use two and I've seen some track guys and racers use one to finesse the application. And as I've said, stainless brake lines do improve the braking consistency and feel of the brakes but not by a large night and day difference. If you've said, he had just installed a new Brembo master or a set of Brembo monoblock calipers, then I would believe it more. It's just poor technique here and not knowing what the bike's brakes can do in a panic situation.
