KTM expand off-road family for 2025 with new 390 and 125 Enduro R models

1 of 10

KTM have lifted the lid on a pair of new small capacity dual sports, introducing the £5699 390 Enduro R and £4899 125 Enduro R, both of which are expected to arrive in UK dealers from March.

The reveal follows the earlier announcement of two SMC R supermoto equivalents released just days previously – suggesting that team orange have no intention of slowing down their roll out of fresh metal, despite the brand’s current economic challenges.

Thrust comes courtesy of the brand’s 399cc and 124.9cc LC4c engines borrowed from the current Duke range. This translates to power figures of 44bhp for the 390 and 14.8bhp for the learner legal 125.

These motors have undergone a few noteworthy changes for their new application, including a new 2kg lighter exhaust, revised cylinder head design, altered airbox, repositioned fuel injectors, and subtle gearbox changes – which is now paired with a slipper clutch as standard.

The new platform comes with updated service intervals – the first check being required at 600-miles, rising to 6200-miles between services thereafter. Valve inspections are called for every 12,400 miles.

Perhaps the biggest question on the lips of prospective buyers will be that of weight. However, KTM remain reticent about this figure at the time of writing.

The earlier announced 125 and 390 SMC R supermotos are quoted at 145kg and 154kg (dry) respectively so expect similar numbers from their dirt orientated siblings.

Aimed squarely at the A2 licence crowd, the 390 will need to be at least 164.2kg with its nine-litre tank brimmed to meet the 0.268bhp per kg restriction for the category – making its 690 Enduro stablemate not only significantly more powerful but also noticeably lighter too. 

On to the chassis and, like with the engine, the frame is largely based on the Duke models, although it does sport new subframe mounts, a revised steering head angle and a 25mm taller handlebar position to suit the off-road persona.

The footpeg location has also moved to accommodate stood up riding and the radiator has shifted to improve clearance.

Wheels for both bikes come in the traditional dual sport configuration of 18/21”, with the rear using a 140mm-section tyre. That unlocks the option to run practically any full on enduro knobblies – although road orientated choices will be limited somewhat.

Suspension comes courtesy of KTM’s WP brand partner and offers 230mm of travel available at either end.

Both bikes use 43mm USD Apex open cartridge forks paired to matching monoshocks. The 390 gets compression and rebound damping adjustability through 30-clicks upfront, but only rebound and preload are tuneable out back.

The more basic 125 makes do with fixed settings for all but rear preload adjustment.

Bodywork is expectedly minimalist, comprising of little more than the bare essentials. Those wanting more in the way of wind protection should look towards KTM’s 390 Adventure R which was revealed last year at the EICMA trade show in Milan as a pre-production model.

Despite the pared back looks, there’s plenty of electronic wizardry going under the surface, including two switchable riding modes for the 390, dual channel ABS on each bike, selectable traction control, and a 4.2” TFT dash providing speed, fuel level and gear position information.
