2018 KTM 790 Adventure R Prototype

The 2018 KTM 790 Adventure R Prototype marks the public debut of what would become KTM's mid-size adventure platform, shown to gauge reaction before anything reached a dealership floor. This isn't a motorcycle you could buy new in 2018 — it's the concept that previewed a parallel-twin adventure bike built to compete with the big-bore machines on tighter, rougher terrain where a lighter chassis actually matters. The riding position, suspension travel, and overall proportions signaled a machine meant for standing on the pegs through rutted trails, not just posing at gas stations, and that off-road-first character carried through when production finally started.

There was no 2018 production run. This prototype existed purely as a show and development model, with the actual 790 Adventure R reaching customers in 2019.

Interest in the 2018 KTM 790 Adventure R Prototype today comes mainly from KTM history followers and early adopters curious about the machine's origins rather than traditional collectors, since no production examples exist from this year to buy, ride, or restore.
