KTM is developing another off-road 390 model

Don’t read this prototype cosmetics too much KTM 390 — Found in tests at the company’s Austrian location — but looking underneath the cohesive bodywork, there’s a whole new frame and suspension. We see it as evidence of the ongoing development of future off-road bias single-cylinder models.

One of the reasons KTM prefers tubular steel trellis frames over aluminum chassis is that they can be easily modified. During bike development, engineers can easily cut and weld steel pipes when manipulating the shape of the bike. In this prototype, KTM doesn’t even need to paint the metal. The layer of rust on the surface may not look clean, but given the short life of the development chassis subject to continuous updates, no extra effort is clearly required for a sophisticated finish. did.

It’s the same story with minimal bodywork, thrown together from the parts bin components just to get the prototype out on the road, the company’s enduro series front fenders, 390 Adventure And an alloy fuel tank that is just a rectangular box. Under the engine, the alloy bash plate is an existing PowerParts option for the 390 Adventure. These parts are not important if your goal is to develop a chassis that goes one step further from the current design.

The new frame itself shares its overall design with the design of the next generation 390 Duke. Planned Husqvarna E-Pilen Electric Bike And the E-Duke version of the KTM brand.Compared to the current chassis used in 390 Duke 390 Adventure, the new design is a more traditional trellis design. Ducati Used for decades. Currently, both 390 models have thick upper frame tubes on either side from the swingarm pivot to the steering head, under which a thin tube of reinforced trellis hangs. In the new design, the upper and lower main tubes are the same thickness, with a triangular layout and slim metalworking between them for added rigidity.

This means that the trellis sections on both sides are higher than before, showing more of the engine and a unique alloy bracket that is much longer than that of the current model to reach the front mount of the engine. will be needed.We have just seen this design Next Generation 125, 250, 390 Duke Spy PhotosAnd it seems that it will be adopted in future off-road models.

The new aluminum swingarm and higher emissions to add ground clearance are also different from the 390 Duke prototype unit. (Bernhard M. Höhne / BMH-Images /)

It is in its swing arm that this machine is diverted from the next generation Duke. Duke’s prototype has already been seen in a near-production swingarm made from cast alloy with a fan-shaped design of external braces on a banana-style right arm that curves over the vent. However, in this prototype, the swingarm appears to be machined from billet aluminum and even more curved. Perhaps it adds the ground clearance and suspension travel required for off-road machines. Exhaust gas is also different, adding an end can so that the Prototype 390 Duke can exhaust gas directly from the collector box under the engine.

The 21-inch front and 18-inch rear wire wheels suggest either the new 390 Adventure or perhaps the 390 Enduro. (Bernhard M. Höhne / BMH-Images /)

If this prototype is for a future 390 adventure, KTM is pushing the bike more off-road, adding 21-inch front tires and 18-inch rear tires to the DID DirtStar wirewheels instead of the 19-inch 17-inch. Indicates that you are. -Existing model inch alloy.The same wheel design is used on other KTMs, including the current KTM 890 Adventure RAnd since both the 1290 and 890 adventure series feature road bias models of alloy wheels and R-flavored versions of wire wheels, it makes sense that the next 390 adventure lineup could include the same options. I am. Alternatively, this prototype could lead to another 390 enduro model. 690 Enduro R In the range as a street enduro with the style of the KTM competition model.

It is unlikely that this particular project will be completed on the 2023 model, as the bodywork remains in a minimal rough prototype format. (Bernhard M. Höhne / BMH-Images /)

In any case, the prototype is clearly still in the early stages of development, so it’s unlikely that you’ll consider the 2023 model here. Instead, KTM’s 390 range improvements will begin with the new 390 Duke in 2023, and the adventures that may have been derived from this prototype could follow the 2024 model.
