• A new KTM RC 390 was spotted undergoing road tests.

• Introduced in 2014, it needs an upgrade/redesign.

• The new bike may be introduced for 2021.

As we speculated, all manufacturers are hard at work to produce new models by 2020 and 2021. But one bike which has gone under the radar for a long time is the KTM RC 390.

The bike made huge waves and sold like hotcakes when it was introduced back in 2014. Soon, they were everywhere. There were also RC 390-exclusive racing series and some owners took it to track days.

The bike was last updated in 2017. But 5 years is a long time (maybe too long) for the model’s product cycle in that cut throat segment.

So, as with the KTM 390 Duke test bike caught testing months ago, a prototype RC 390 was also spied over the weekend.

According to RideApart, the new bike will debut in 2021.

Changes to the new bike is immediately noticeable as KTM redesigned the bike: the front fairing has a similar profile, but the rest of the bodywork are different. Even the rear seat is different and takes a contemporary design instead of the current single-seat look.

Also gone is the lattice work of the rear subframe. The handlebars appear to be mounted higher for more comfortable ergonomics.

The new bike will of course be Euro 5 compliant, but there are no details yet if there are any power upgrades.
