BMW is preparing to add a new model to its 1,802cc boxer family, receiving type approval in Switzerland for a new variant called the R 18 Roctane.
The type approval data for the Roctane shows much in common with the existing R 18 models, but with some notable differences. For one, the R 18 Roctane has an internal model code of “0N61,” while the model codes for the R 18, R 18 Classic, R 18 B, and R 18 Transcontinental all have model codes beginning with “0L.” This suggests the Roctane differs from the other models in a fairly significant way, either with a chassis update or a different form factor. The variant’s name appears to be a combination of the “R” branding and “octane,” so a more performance-focused model may be in store.
This brings to mind the Concept R 18 /2, which BMW revealed in 2019. The “Slash Two” was presented as the stylistic opposite of the retro-inspired concept that eventually became the R 18. BMW described it as “a modern, dynamic custom cruiser with a performance appeal that is somewhat rougher round the edges” We’re not too crazy about the Roctane name, but it does seem a fit for the R 18 /2.
Performance focus or not, we do know the Roctane is powered by the same 1,802cc air-cooled Boxer as the rest of the R 18 range. The homologation filing confirms the same engine code and peak performance numbers as the other models: a maximum power output of 67 kW (90 hp) at 4,750 rpm, and 116 lb-ft. at 3,000 rpm. As with the rest of the range, BMW has also gained type approval for a 35 kW (47 hp) version suitable for European A2 licenses. The filing also confirms the Roctane has the same silencer code as the Classic, B, and Transcontinental models, so we can expect the same straight pipes and not the bulbous fishtail exhaust on the regular R 18.
