Hey beryllium guys, remember one thing.
Unless you are a competitive Superbike rider, the bike you ride on the track is almost irrelevant.
I've killed lots of dealership racers on the track on my Busa, and I've also been killed by a 125 GP bike in the hands of a great rider. On a long track...Mosport.
I've been killed on the track by a 1200 Bandit, a BMW boxer, and all kinds of embarrassing old clunky bikes.
Fortunately, never by a Harley.
I lap Mosport (1:41) within about 10 seconds of current superbikes (1:28 qualifying, 1:31 racing) on my all-but-stock Busa. All the beryllium, carbon fiber, titanium and billet pieces in the world are not going to improve my times one tenth.
A fast rider can beat me on a Harley 750 flat tracker on my best day.
Stay humble. Beryllium is no substitute for riding skill.
