The A2 supermoto class finally matters again

For a decade the small supermoto class was one bike deep. In 2025 the KTM 390 SMC R and the reborn Suzuki DR-Z4SM turned it into a real fight. Here is how to choose.

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.
