Quick 60-Second Pre-Ride Checklist for the 2018 KTM RC 390 Motorcycle

  • Tires & wheels – visual check for pressure, cuts, and proper tread depth.
  • Brakes – lever feel and rear pedal pressure; confirm lights illuminate when applied.
  • Chain & sprockets – correct slack and a light layer of chain lube.
  • Fluids – oil level and coolant visible in the reservoir; no puddles under bike.
  • Controls & lights – smooth throttle return, clutch engagement, working headlamp/turns.
  • Suspension & frame – quick look for leaks, dents, or loose hardware.
  • Final check – mirrors set, kickstand up, and helmet/gear ready.

Tires and Wheels

The 2018 KTM RC 390 Motorcycle is a sport-oriented street bike that relies on correct tire pressure for predictable handling. Check pressures cold before you ride; the recommended front and rear pressures are tuned for street performance and should be close to what you normally run for solo riding.

Scan sidewalls for cuts, embedded debris, or visible cords. Tread wear indicators should stay above legal minimums — uneven wear can signal alignment or suspension issues. Spin each wheel to confirm the tire beads sit flush and there are no odd noises from bearings.

Brakes

Braking on the RC 390 must be crisp and reliable. Squeeze the front lever and press the rear pedal individually to confirm firm, consistent resistance. Spongy feel can indicate air in the line or low fluid.

Inspect visible brake pads through the caliper ports; if pad material is thin, plan replacement. Check the master cylinder reservoir level for both front and rear systems; fluid should be within the recommended sight lines and free of discoloration.

Chain / Drivetrain

The 2018 KTM RC 390 Motorcycle uses a conventional roller chain. With the bike on its sidestand or center stand, measure chain slack mid-span between sprockets. There should be a small amount of play but no excessive sag.

Lubricate the chain where rollers and pins meet, especially after wet rides. Rotate the rear wheel and look for tight spots, heavy rust, or sprocket tooth wear. Replace the chain or sprockets if teeth appear hooked or uneven.

Fluids

Glance at the engine oil sight glass or dipstick for level and color. The RC 390's single-cylinder engine runs hot; maintaining correct oil level protects internal components.

Coolant reservoir should be within marked levels and the fluid clear. Check brake fluid visibility in both reservoirs. Low levels often point to pad wear or a leak, which requires immediate attention.

Controls and Lights

Test throttle action for smooth, immediate return when you twist off. Any sticking or lag requires cleaning or cable adjustment. Pull the clutch lever to ensure full engagement and free play at the perch is within a comfortable range.

Switch on the headlight, low and high beam, then activate turn signals and hazard if equipped. Have someone confirm that brake light illuminates when pressing the rear brake; a failed bulb or connector reduces your visibility dramatically.

Suspension and General Condition

Look over the forks for oil seepage at the seals; any wetness calls for service. Compress the front and rear suspension to feel for binding, bottoming, or excessive play in the linkage.

Walk around the 2018 KTM RC 390 Motorcycle to inspect the frame, fairings, and fasteners. Tighten any loose bolts you can access easily, and note anything that looks bent, cracked, or out of place before heading out.

Final Safety Check Before Riding

  • Kickstand & mode – ensure the bike detects kickstand up if required for ignition and that it folds cleanly.
  • Mirrors – set for a clear rear view without shifting your riding position.
  • Gear readiness – helmet, gloves, jacket, and boots secured; remove items from pockets that might tangle with controls.
  • Quick engine idle – start the RC 390, listen for unusual noises, confirm charging lamp goes out, and let the bike warm briefly.

Conclusion

Make the PreRide Checklist for a 2018 KTM RC 390 Motorcycle a routine part of every ride. A disciplined, focused walkaround prevents unexpected failures and keeps the bike handling like it should. Consistent checks protect you and preserve the RC 390's performance ride after ride.
