BMW R 18: the largest boxer engine, versions and what to check
BMW R 18 (from 2020) — BMW cruiser with the largest series boxer engine — 1802 cm³ twin-cylinder engine. We look at what sets apart the R 18, R 18 Classic, R 18 B and R 18 Transcontinental, what the engine offers and what to check when buying used.
R 18 in brief
The R 18 is designed as a BMW motorcycle inspired by the vintage R5 and R 50 models. It features a large boxer engine, an open driveshaft, a classic look and modern electronics.
This is a cruiser designed for relaxed, comfortable riding, not for sport. It's heavy, but stable and makes a striking impression with its appearance.
Versions — what sets them apart
The first version is the R 18 (2020), often referred to as the “First Edition”. Later came the R 18 Classic with a larger windshield and saddlebags, the R 18 B (Bagger) and the R 18 Transcontinental with a full fairing and touring equipment.
Differences — fairing, saddlebags, comfort and safety features. When buying, check which specific version and what equipment it has.
Engine and running gear
Engine — 1802 cm³ twin-cylinder boxer, around 91 hp, torque — around 158 N·m. It pulls strongly from low revs and sounds distinctive.
Gearbox — six-speed, rear wheel driven by driveshaft. The motorcycle is heavy, yet stable. There are several riding modes, traction control and ABS.
What to check when buying a used R 18
Request the service history and check if manufacturer recalls have been carried out based on the VIN. Inspect the chrome details, boot, paintwork, and exhaust system for any signs of corrosion or scratches.
Check the operation of the electronics, ABS, brakes, driveshaft, and rear differential. Pay attention to the oil level, leaks around the engine, and the condition of the driveshaft joints. Additional equipment (fog lights, roof rack) should be in good condition and working.
