Compare motorcycles. The numbers decide.

I score every bike out of 100 from its published specs, and I show the working. No sponsors, no press trips, no home-crowd calls.

How the points work

100 points, six categories, fixed weights. Every input is normalized within the bike's class, so a commuter is never punished for lacking superbike power. No editorial thumb on the scale: same data in, same score out. Boring, exactly the way a referee should be.
