# KTM RC 125 — Full Specifications 2026 > Complete technical specifications for the KTM RC 125. Source: https://indianautoforum.com/bikes/ktm/rc-125/specifications The KTM RC 125 is powered by a 124.7cc single-cylinder, liquid-cooled, 4-valve DOHC engine - the same bottom end that powers the KTM 125 Duke. It produces 14.5 PS at 9,250 rpm and 12 Nm of peak torque at 8,000 rpm, mated to a 6-speed gearbox. ARAI-certified fuel efficiency stands at 41 kmpl, and real-world city usage typically returns 36-39 kmpl depending on how hard you ride. What makes the RC 125's spec sheet special isn't the engine - it's everything around it. The front end gets 43mm WP APEX open-cartridge USD (upside-down) forks - the same units fitted to the RC 200. At the front wheel sits a 320mm petal disc gripped by a radially-mounted 4-piston BYBRE fixed caliper, a setup you'd more commonly see on mid-displacement sportbikes. The rear uses a 230mm disc with a single-piston caliper. Single-channel ABS is standard. The chassis is a steel trellis frame identical to the one used in the RC 200 and RC 390, giving the 125 genuinely responsive steering and composed mid-corner stability. Wheelbase is 1,340mm, rake is 22.5 degrees, and the overall geometry is race-oriented - this is not a comfort-first setup. Kerb weight is 160 kg and seat height is 824 mm, which makes it approachable for most Indian riders in the 5'5" - 6'0" range. The 13.7-litre fuel tank is inspired by KTM's RC4 race bike and is the largest in the 125cc class. Tyres are MRF Revz radials - 110/70 R17 front and 150/70 R17 rear - on 17-inch alloy wheels. ## Brakes & Wheels | Spec | Value | |------|-------| | ABS | Yes | | Front Brake | Disc Brakes | | Rear Brake | Disc Brakes | | Wheel Type | Alloy Wheels | ## Dimensions | Spec | Value | |------|-------| | Fuel Tank Capacity | 13.7 litres | | Kerb Weight | 160 kg | | Seat Height | 824 mm | ## Power & Performance | Spec | Value | |------|-------| | Displacement | 124.7 cc | | Emission Standard | BS6 | | Max Power | 14.34 bhp | | Mileage - Owner Reported | 39 kmpl | | Top Speed | 120 kmph | | Transmission Type | 6 Speed Manual | The RC 125's standout spec is its hardware-per-rupee equation on the chassis side. No other 125cc sportbike in India gives you USD forks, radial brakes and an RC390-derived trellis frame. The trade-off is ergonomics - the fully-faired, tucked-in position is true to the race-bike inspiration and will fatigue your wrists and back on long urban slogs. If you're planning to spend most miles on open roads or a track day, the RC 125 rewards you. If the bike mostly sits in Delhi traffic, your body will ask questions your brain won't want to answer. ## FAQs **What is the engine displacement of the KTM RC 125?** The KTM RC 125 uses a 124.7cc single-cylinder, liquid-cooled, 4-valve DOHC engine - the same unit found in the KTM 125 Duke. It produces 14.5 PS at 9,250 rpm and 12 Nm of torque at 8,000 rpm, mated to a 6-speed gearbox. **What is the fuel efficiency of the KTM RC 125?** The KTM RC 125 delivers an ARAI-certified fuel efficiency of 41 kmpl. In city riding conditions, real-world efficiency ranges between 36-39 kmpl, while highway cruising returns 42-45 kmpl. The 13.7-litre fuel tank gives an estimated range of approximately 500 km between fill-ups. **What are the dimensions and kerb weight of the KTM RC 125?** The KTM RC 125 has a kerb weight of 160 kg, a seat height of 824 mm, and a wheelbase of 1,340 mm. Overall dimensions are 1,988 mm (length) × 820 mm (width) × 1,098 mm (height). The 824 mm seat height is manageable for riders above 5'5" tall. **Does the KTM RC 125 get ABS?** Yes, the KTM RC 125 comes with single-channel ABS as standard. It operates on the front wheel, paired with a 320mm disc and a 4-piston radially-mounted BYBRE caliper. The rear uses a 230mm disc with a single-piston caliper but no ABS. **What suspension setup does the KTM RC 125 use?** The KTM RC 125 uses 43mm WP APEX open-cartridge USD (upside-down) forks at the front - the same units fitted to the RC 200 - with 150mm of travel. The rear gets a WP APEX monoshock with adjustable preload. This hardware is shared with higher-displacement RC siblings and is the single biggest differentiator versus Japanese 125cc rivals. ## More - [Overview](/bikes/ktm/rc-125) - [Variants & Prices](/bikes/ktm/rc-125/variants) - [Price in India](/bikes/ktm/rc-125/price)
