R 18 Transcontinental (MY2021)
Big Boxer Goes Full Dress
The Machine's Character
The Transcontinental takes BMW's 1802 cc air/oil-cooled boxer and wraps it in a full touring shell. Peak output is 91 hp at 4,750 rpm, but the figure that actually shapes the bike is 117 lb-ft at 3,000 rpm, fed through a six-speed box and a shaft. Everything built around it serves distance: a fixed fairing, a factory luggage system, a large TFT screen with full map navigation, keyless operation, heated grips and cruise control, all standard. This is BMW doing the full-dress bagger on its own hardware, with its own idea of finish and its own electronics.
On the road it behaves the way the numbers promise. A 66.7 in wheelbase and 944 lb wet settle the bike into a lane and hold it there, and the low 29.1 in seat gets most riders both boots down at a stop. It is made for people who measure a good day in states crossed rather than corners strung together. The honest caveat is mass. Below walking pace you feel every one of those pounds, and parking on a camber takes a plan. The telescopic fork carries no adjustment at all, and the rear shock's preload is automatic — an electro-hydraulic load-compensation system, not a knob you turn yourself.

Known issues
-
Reverse gear control unit seal may leak and overheat
The seal of the reverse gear control unit can deteriorate, allowing moisture ingress that may cause the unit to overheat and create a fire risk. NHTSA campaign 24V-716 covers certain 2021-2024 BMW R18 motorcycles fitted with the reverse gear; the remedy replaces the control unit.
-
Headlight low‑beam reflector may detach
Attachment points of the low‑beam reflector can break, causing the reflector to shift out of position, reducing road illumination and potentially causing glare for oncoming traffic. A recall (NHTSA 23V-884) covers all 2021‑2024 R 18 B and Transcontinental models; a remedy is still under development.
