2022 KTM RC 390 Overview

For 2022, KTM offers the RC 390 as a sport motorcycle with 373 cc on tap. The 2022 KTM RC 390 is built around a Four stroke, single cylinder, DOHC with finger followers, 4 valves per cylinder engine. Out on the road, the RC 390 delivers 32 kW @ 9500 rpm of peak power and 37 Nm of torque. In everyday use, the 2022 RC 390 tips the scales at 155 kg, carries a 13.7-litre fuel tank and offers a seat height of 824 mm. That's roughly 47.7 kg lighter than the average sport motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2022 KTM RC 390 spec sheet below.

2022 RC 390 - Pros & Cons

Strengths

Strong power output: Peak output on the RC 390 is 32 kW @ 9500 rpm and 37 Nm of torque - strong numbers for what it is.
Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.

Considerations

Tall seat height: A 824 mm seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.

Wear Points & Servicing Notes

Cooling system servicing

With Liquid Cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.

Fuelling & injector care

Fuelling on the RC 390 comes from Bosch Injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.

Brake disc and pad wear

Single 320 mm disc 4 piston radial fixed ByBre calliper up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by USD WP APEX 43 up front and WP APEX - Monoshock at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Frame & chassis check

The Steel trellis frame, powder coated and bolt-on subframe chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.

RC 390 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2022 KTM RC 390 should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept RC 390 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a RC 390's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.

Fuel system care

Injector systems like the RC 390's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
