2024 KTM RC390 Specs & Review

KTM’s small-bore supersport keeps the focus on lightweight thrills, sharp handling, and everyday usability. If you want a lively single-cylinder sportbike that’s as happy commuting as it is ripping backroads, the 2024 KTM RC390 specs deliver a compelling package. This KTM RC390 review breaks down the numbers and how they feel on the road.

Key Specs at a Glance

  • Engine type: 1-cylinder, 4-stroke engine
  • Displacement: 373 cm³ (22.8 in³)
  • Power: 32 kW (42.9 hp)
  • Torque: 37 Nm (27.3 lb-ft)
  • Wet weight: ~171.7 kg (379 lbs)
  • Seat height: 824 mm (32.44 in)

Engine & Performance

The RC390’s 373 cm³ single is the heart of its playful character. With 32 kW (42.9 hp) and 37 Nm, it’s eager off the line and responsive in the midrange—perfect for slicing through city traffic and blasting between corners. Bosch EFI with a 46 mm throttle valve and Bosch EMS with RBW (ride-by-wire) ensure precise fueling and crisp throttle response, while the liquid-cooled design keeps performance consistent lap after lap.

A 6-speed transmission paired with a PASC antihopping (slipper) clutch adds confidence when downshifting aggressively and smooths out hard corner entries. Fuel efficiency is a strong suit at 3.46 l/100 km (0.91 gal/100 miles), and CO2 emissions are listed at 81 g/km—useful if you care about running costs and a lighter footprint. Electric start convenience is standard, and the 520 X-Ring chain keeps drive reliable and low maintenance for daily use.

Handling, Comfort & KTM RC390 Seat Height

Chassis feel is a highlight. The steel trellis frame and steel trellis rear subframe are light yet rigid, feeding communicative feedback through the WP APEX 43 front end and WP APEX rear monoshock. Suspension travel is 120 mm up front and 150 mm at the rear—enough compliance for rougher urban streets while staying taut for sporty rides. A wheelbase of 1343 mm (52.87 in), a steering head angle of 66.5°, and ground clearance of 158 mm (6.22 in) give the RC390 a quick-turning yet stable nature.

The KTM RC390 seat height is 824 mm (32.44 in). Combined with the KTM RC390 weight of ~171.7 kg (379 lbs) wet, lower-speed maneuvering is friendly, making U-turns and tight parking a breeze. Steel clip-on handlebars set a sporty posture without going extreme; shorter riders should find it approachable, while taller riders still get enough room to move around on spirited rides.

Equipment & Features

Braking is a standout: a four-piston radial fixed caliper clamps a 320 mm front disc, while a single-piston floating caliper bites a 230 mm rear disc. Bosch 9.1MP Two Channel ABS (Supermoto ABS) adds security in the wet and lets you dial up fun by allowing controlled rear-wheel slide in Supermoto mode.

Other useful touches include:

  • Bosch EMS with RBW and Bosch EFI (46 mm throttle valve) for refined fueling
  • WP APEX suspension (43 mm fork, rear monoshock)
  • Cast aluminium wheels for low unsprung weight
  • 13.7 l (3.62 gal) tank capacity
  • Stainless steel primary and aluminium secondary silencer
  • Steel trellis frame, powder coated, with a steel trellis rear subframe

Cooling is liquid, the starter is electric, and the 6-speed box works with the PASC antihopping clutch to keep the RC390 composed under hard riding.

Who Is the 2024 KTM RC390 For?

  • New riders: Manageable power, a reasonable 824 mm seat height, ~171.7 kg wet weight, and ABS make it unintimidating while still exciting.
  • Daily commuters: Light clutch action, strong fuel efficiency (3.46 l/100 km), and agile manners excel in the city.
  • Weekend track or canyon riders: Responsive chassis, stout brakes, and communicative suspension deliver the precision that rewards skill progression.

If you’re cross-shopping lightweight sportbikes, the 2024 KTM RC390 specs hit a sweet spot of performance and accessibility.

Torquepedia Verdict

The RC390 brings big-bike features to the lightweight class: a trellis frame, WP APEX suspension, strong braking hardware, and sophisticated electronics like Bosch 9.1MP ABS and RBW. Its single-cylinder punch, 6-speed gearbox, and slipper clutch make it a willing partner for both daily duty and spirited rides.

Downsides? The clip-on ergonomics lean sporty, which some commuters may find less relaxed. But as an all-rounder that prioritizes fun, control, and value, this KTM RC390 review finds it one of the most engaging choices in its segment.
