2017 KTM RC 390 Overview

KTM RC 390 is a sport motorcycle, displacing 373 cc. Power comes from a Four stroke, single cylinder, DOHC with finger followers, 4 Valve per cylinder engine, a compression ratio of 12.6:1. On the performance side, it delivers 32 kW @ 9500 rpm of peak power and 35.3 Nm of torque. On the road, the 2017 RC 390 tips the scales at 149 kg, carries a 10-litre fuel tank, offers a seat height of 820 mm and spans a 1340 mm wheelbase. That's roughly 53.7 kg lighter than the average sport motorcycle in our database. The full 2017 KTM RC 390 spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2017 RC 390 - Pros & Cons

Strengths

Strong power output: With 32 kW @ 9500 rpm and 35.3 Nm of torque on tap, the RC 390 is no slouch for its class.
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.

Considerations

Tall seat height: At 820 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
Modest fuel capacity: Range between stops is limited by the 10-litre tank - plan fuel stops accordingly on longer routes.
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.

Wear Points & Servicing Notes

Cooling system servicing

RC 390's Liquid Cooled setup is low-maintenance provided the coolant interval is kept - old, acidic coolant is the main cause of long-term corrosion in the water passages.

Fuelling & injector care

The Bosch Injection on the RC 390 needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Brake disc and pad wear

Braking up front comes from Single 320 mm disc 4 piston radial caliper - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The RC 390's suspension runs WP Suspension Up Side Down at the front. The rear uses WP Monoshock. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The RC 390 uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.

Frame & chassis check

Built around a Tubular space frame made from steel, powder-coated, the RC 390's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

RC 390 - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2017 KTM RC 390, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy RC 390 should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a RC 390's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Fuel system care

Fuel injection on the RC 390 needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
