In its home market, the 390 Duke's engine size and weight place it in the mid-range category, and it sells for more than three times the average price of a motorcycle in India. The Duke 390 in India gained new features and updates. The Duke 390 comes with a daytime running light, and is on Euro IV emission standards. 2020 update The bike was made BS6 compliant and a bi-directional quickshifter was added. 2022 update 3 new colors are available for the 2022 Duke, which was launched in Egypt at an ex-showroom price of .

The new engine, called the LC4c, was 399cc compared to the old 373cc and also made more power and torque with peak power being approximately and peak torque now being . The chassis and subframe were also entirely new. To allow for a bigger airbox, KTM moved the rear monoshock to the right which also allowed them to reduce the seat height from 820mm in the older models to a more accessible 800mm. However, an accessory 820mm seat is still offered by KTM. Due to these changes, the ground clearance too went up significantly from 150mm to 183mm. And this was the first time the Duke 390 received fully adjustable suspensions at both the front and rear. The girl tank capacity also went up from 13.5L to 15L. The brakes received a significant upgrade as well with the front brake now being a wheel mounted disc over the regular, hub-mounted disc unit on the old bike. 2025 update The LC4c engine still made and but received an improved transmission and optimized cylinder head for a smoother power delivery and lighter weight. A 5″ bonded-glass TFT display with turn-by-turn navigation, music, and call integration was offered. The three ride modes - Street, Rain, Track - were still on offer. Launch Control is standard and has been so since 2023 but is unlocked only after covering the first 1000kms. Cruise control also became a standard and three new buttons on the left side switch gears were added for the dedicated cruise control mode with pedal switches to increase or decrease the cruise control speed on the fly. 2026 update After India brought revised GST rates in September 2025 which increased the GST rates of bikes above 350cc from 28% to 40%, KTM-Bajaj decided to launch sub-350cc KTM models which would be sold alongside the existing 399 cc models. A new moniker, the Duke 390 R, was created by KTM to denote the 399cc bikes while the Duke 390 moniker went to the new, sub-350cc engine which now made less power and torque than their 399cc counterparts. Earlier in this year, KTM also decided to switch from a ByBre brakes setup to a WP brakes setup. ==390 SMC R==

The KTM 390 Adventure is an Adventure Touring motorcycle produced by KTM, first introduced in 2020. It was essentially the 373cc, 390 Duke with added features and refined dimensions. The engine produced approximately 31 kW (43 hp) at 9,000 rpm; maximum torque was 37 Nm at 7,000 rpm. Power was transmitted to the rear wheel via a 6-speed gearbox and a chain. From 2020 to 2023 it came with 19" front and 17" rear cast aluminum rims. The suspension consists of a 43 mm WP upside-down fork and a monoshock rear suspension system, both of which are adjustable. The 2024 Adventure had 19/17 wire spoked wheels. The speed, rpm, gear, and fuel level of the KTM 390 Adventure were displayed on a TFT display. Other features include cornering ABS, dynamic traction control, and Bluetooth connectivity to a smartphone. The motorcycle was available in orange and black or gray and white. One particular 390 Adventure, assembled in January of 2023 at the Indian cooperation partner Bajaj Auto, was the 1,000,000th KTM motorcycle made since production began there in 2007. In 2025, KTM replaced the 390 Adventure in the lineup with the 390 Adventure X, now sporting the new 398.6 cc LC4c motor. The Adventure X is a stripped down version of the more well equipped KTM 390 Adventure R. The X gets 19-inch front and 17-inch rear cast wheels. The KTM 390 Enduro R is released in 2025 sporting the new 398.6 cc LC4c motor previously introduced in the 390 Duke. Premimum features include better seated and standing positions, a 4.2” TFT display, electronic fuel injection, ride-by-wire throttle, a balancer shaft, slipper clutch, traction control (street / offroad) and ABS. The redesigned "trellis" frame and improved subframe allows for 21"/18" wire spoke wheels and a 35 inch seat height. The Dual Sport version of the 390 designated as the 390 Enduro R and the Adventure Touring versions designated the 390 Adventure R and 390 Adventure X are all derived of the 390 Duke. The differences between the street-biased X and off-road-focused R primarily involves the wheels, tires, and suspension. Each model has tires suitable for the bikes intended use. ==Notes==
