KTM RC 125: 125 cm³ sport bike, A1 category
KTM RC 125 (from 2014) — a fully faired 125 cm³ sport bike, designed for A1 category riders and younger motorcyclists. We look at what sets the RC 125 apart, its engine and chassis, and what to check when buying used.
RC 125 in brief
RC 125 — the smallest KTM sport bike, styled and spirited like its bigger RC siblings. It features full fairings, a tubular steel frame, and a sporty, yet not overly extreme riding position.
This bike is for those with an A1 licence or just starting out, but who want the look and feel of a sport bike. It's light, agile, and easy to handle, but not very comfortable for longer journeys due to its modest power.
Generations — what's the difference
The first generation (2014–2021) has the distinctive KTM design with open frame elements and bold colours. Over the years, the bike underwent several updates: changes in colours, graphics, and minor details.
The new generation introduced around 2022: features a new design, updated frame, and more modern equipment. Before buying, check which generation a specific example belongs to, as parts and equipment may vary.
Engine and chassis
The engine is a 124.7 cm³ single-cylinder, liquid-cooled, with around 15 hp, which meets the A1 category limit. It pulls strongly, but is weaker at lower revs, so it's worth keeping the revs higher while riding.
Gearbox — six-speed, rear wheel driven by chain. ABS is used, and the handling is stable and precise, making it great for cornering and learning sporty driving.
What to check when buying a used RC 125
Due to its low power, it often runs at high revs, so ask for the service history: regular oil changes and valve adjustments are very important. Listen to the engine — it should start easily when cold and run smoothly.
Check the chain and sprockets, brakes, ABS operation, cooling system, and fork seals. Small sport bikes are often dropped while learning to ride, so inspect the fairing, handlebars, and frame for any dents, cracks, or signs of repair.
Trims and versions
Names and equipment vary by market and year; we list the versions most commonly found in Europe.
