RC 390 (MY2025)

The Featherweight Corner Weapon

The Machine's Character

The RC 390 is built around one idea: a small, hard-edged sportbike that lets a rider work on line, lean, and braking without ever feeling overwhelmed. The 373 cc liquid-cooled single makes 44 hp at 9,000 rpm and 27 lb-ft at 7,000 rpm, and the whole package is light enough that those numbers land harder than they read. Cornering ABS, traction control, and ride modes come standard, as does a slipper clutch, a TFT display, and suspension you can adjust at both ends. That is a genuinely serious spec sheet for a bike this size, and it puts the RC in the sharp end of the small-bore supersport class.

Ridden hard, this thing is all about direction changes. It leans deep, changes line mid-corner without drama, and holds a steady arc at speed instead of running wide. City work is easy, running costs stay low, and the aftermarket support means an owner can keep building on it for years. Who it suits: a rider who wants to sharpen technique on tight, twisting roads or a circuit, not one chasing straight-line speed. That single runs out of breath on a long highway slog, and the riding position is committed. Neither is a flaw, but both are real.

A winding two-lane asphalt road in the Appalachian mountains, photographed in dry daylight. Yellow double-center line markings guide through a series of tight left-hand curves. Dense deciduous and evergreen forest flanks both sides; a rock cut is visible on the right. The road surface and geometry suggest a technical, high-traffic riding corridor popular with motorcyclists.
