KTM 390 SMC R: The 2025 KTM 390 SMC R is here to shake up the supermoto segment with its aggressive pricing, punchy performance, and hooligan-friendly character. This bike undercuts rivals like the Suzuki DR-Z400SM by nearly 40%, making it one of the most accessible supermotos on the market. But does it deliver where it counts? We put it through its paces on city streets, twisty backroads, and even a track to find out.
Engine & Performance: Small but Mighty
- At the heart of the 390 SMC R lies a 398cc LC4c single-cylinder engine (up from 373cc), delivering:
- 44 hp @ 8,500 rpm
- 28.8 lb-ft torque @ 7,000 rpm (+1.8 lb-ft over last gen)
- 6-speed gearbox with optional quickshifter
Real-World Ride Impressions:
- 0–60 mph: ~5 seconds (estimate)
- Top speed: 92 mph (indicated)
- Fuel efficiency: ~55 mpg (2.4-gallon tank = ~120-mile range)
Chassis & Handling: Supermoto DNA Unleashed
- KTM borrowed the steel trellis frame from the 390 Duke but tweaked it for supermoto duty:
- WP Apex 43mm forks (30-click adjustable compression/rebound)
- WP Apex rear shock (preload + rebound adjustable)
- Michelin Power 6 tires (110/70-17 front, 150/60-17 rear)
On the Road:
- Flickable like a dirt bike but stable at speed
- Soft suspension soaks up potholes (great for street, soft for track)
- Nimble steering thanks to the narrow 110-section front tire
Weight?
Also Read
- 339.5 lbs (wet, no fuel)
- 354 lbs fueled (heavier than the DR-Z400SM but lighter than most nakeds)
Electronics: Simple but Effective
- 4.2-inch TFT dash (Bluetooth, turn-by-turn nav via KTM app)
- ABS with Supermoto Mode (disables rear ABS for slides)
- Traction control (on/off—no lean-angle wizardry)
- Street & Sport ride modes (throttle response tweaks)
Brakes & Stoppies: One-Finger Power
- Front: 4-piston radial caliper + 320mm disc (strong bite, non-defeatable ABS)
- Rear: Single-piston caliper + 240mm disc (ABS defeatable)
Comfort & Ergonomics: Not for Touring
- Seat height: 33.8 inches (tall for riders under 5’8″)
- Seat padding: Firm (okay for 1–2 hours, painful beyond)
- Riding position: Upright dirt-bike stance (great for control, bad for wind protection)
