As  KTM fanboys eagerly await the launch of KTM’s 1390 Super Duke range in 2024, the Austrian motorcycle manufacturer is also giving its loyal off-road and supermoto market a taste of what’s to come.

• Recent sightings of prototype versions for the 690 SMC R and 690 Enduro R suggest significant updates are on the horizon.
• the 2025 model year is expected to also feature a heavily revised 692.7cc single cylinder engine. 

A Sleek New Look

At first glance, the prototypes sport matte black finishes, indicating their pre-production status. While their overarching aesthetic closely mirrors their current counterparts, closer examination reveals noticeable changes in bodywork.

Shared features between the SMC R and Enduro R models, such as styling, remain consistent, but modifications have been made to the front nose cowl and fender. Interestingly, the new fender is borrowed from the GasGas ES 700 and SM 700 models. 

Revamped side panels encasing the tank have also been redesigned for a more aerodynamic feel, seeming to envelop a larger radiator—hinting at significant engine modifications.

Under the Hood: More Than a Facelift

The engines of these prototypes appear to have undergone a comprehensive overhaul. While still based on the 692.7cc engine, there are cues that suggest an expansion beyond the 700cc mark. Observations reveal new billet alloy covers for both the clutch and generator, redesigned main engine castings, and changes to the cylinder bracing.

Though the cylinder head looks relatively unchanged, these alterations imply that the engine could offer a longer stroke and potentially a larger bore, aiming for a more robust performance.

Chassis and Frame Tweaks

The frame architecture remains largely similar to existing models but features a modified plate for the front engine bracket to accommodate the revamped engine. Additionally, the footpeg hangers for passengers have been extended, shifting backward and upward in their positioning.

Tail-end Changes

On the rear end, both models appear to feature redesigned bodywork. While side bags obscured the changes on the Enduro R in the spy photos, visible adjustments were made to the lower rear side panels of the SMC R, revealing more of the exhaust. This is in line with a potentially upgraded engine, as the exhaust exhibits a hand-welded finish. 

What’s Being Retained?

Not everything is changing. Elements like the swingarm, WP shocks, forks, brake calipers, and wheels seem to be carryovers from the current 690 series models.

A 2025 Arrival?

While KTM is known for its somewhat lax approach to hiding prototypes, the state of these spotted models suggests they are more likely to hit the market for the 2025 model year rather than in 2024. Following suit, KTM’s sister companies, GasGas and Husqvarna, are expected to launch their own versions, offering a stylistic alternative for consumers.
