KTM RC 390 has shorter wheelbase of 1340 mm while Ninja 300 is significantly longer at 1405 mm. Hence KTM RC 390 could be easily manoeuvrable in city traffic. Ground clearance of RC 390 is 157 mm, which will come in handy while running into rough patch, while Ninja 300 has only 140 mm, which is more urban focused. KTM RC 390 has 830 mm rider seat height and Kawasaki Ninja 300’s seat is 785 mm from ground, almost as short as commuter bikes.
Engine – KTM RC 390 uses same engine driving Duke 390, single cylinder 373.27 cc naturally aspirated petrol engine with 4 valves and Dual Over Head Camshaft (DOHC) producing 43.5 PS max. power at 9,000 rpm and 35 Nm peak torque at 7,000 rpm. Whereas, power house in Kawasaki Ninja 300 is a parallel twin cylinder 296 cc unit with 8 valves and DOHC, generating 39 PS at 11,000 rpm and 27 Nm at 10,000 rpm. Both engines are mated to 6 speed claw shift type transmission. KTM RC 390 remarkable outperforms Ninja 300 with 262 PS / tonne power to weight ratio, while latter sports only 227 PS / tonne.
Technology – KTM RC 390 has contact-less, controlled, fully electronic ignition system with digital ignition timing adjustment, while Ninja 300 has Transistor Controlled Breakerless Ignition (TCBI) with digital advance. Electronic Fuel Injection (EFI) system of KTM RC390 is developed by Bosch and Kawasaki Ninja 300 has Dia 32 mm x 2 (Keihin) injector, with dual throttle valves. Engine cooling system in KTM RC 390 is primarily liquid cooling system (water-cooled) with continuous circulation of cooling liquid with water pump, but front fairing houses special sir deflectors to promote air cooling for better heat dissipation. This is claimed to be more efficient than same engine in KTM Duke 390, in which high heating is often addressed as an inconvenience. Kawasaki Ninja 300 has similar Kawasaki Air Management System (KAMS) and liquid cooling system.
Suspension – On front, KTM RC390 has Up Side Down (USD) fork from WP Suspension which is 43 mm in diameter and has travel of 125 mm. Rear swing arm in RC 390 has WP monoshock with 150 mm travel.
