The R 18 is BMW Motorrad’s big-bore boxer cruiser built for riders who crave classic looks and torque-rich character with modern safety. If you’re cross-shopping heavyweight cruisers, the 2024 BMW R18 specs reveal a machine focused on feel, stability, and mechanical simplicity. This BMW R18 review highlights how its massive twin and low stance translate to real-world riding.
At the heart is an 1802 cm³ air/oil-cooled two-cylinder boxer with two chain-driven camshafts above the drive shaft. Output is a stout 67 kW (91 hp) at 4750 rpm, but it’s the 158 Nm at 3000 rpm that defines the R 18. In the city, that low-end torque lets you short-shift and surf the wave of grunt with minimal effort. On the highway, it settles into a relaxed lope, pulling cleanly for overtakes without frantic downshifts.
BMW pairs electronic intake pipe fuel injection with BMS-K+ engine management, twin-spark ignition, and e-gas (BMS-O) for crisp response and efficient combustion. A regulated three-way catalytic converter helps keep emissions in check, with CO2 listed at 129 g/km (based on WMTC). Fuel consumption is a claimed 5.6 l/100km, and fuel type is Super plus lead-free (max. 15% ethanol, E15) ROZ 95 90 AKI.
A 6-gear shifting claw transmission, single-disk dry clutch, and shaft drive deliver the traditional, connected feel cruiser riders want. Top speed is stated as over 110 mph, which suits its long-legged character.
The BMW R18 seat height is a very approachable 690 mm (27.17"). Shorter riders will appreciate the ability to flat-foot, while taller riders still get a roomy stance, aided by a rider step length of 1630 mm. Stability is a headline: a 1731 mm wheelbase, 57.3° steering head angle, and 150 mm castor underscore its relaxed geometry.
Suspension is straightforward and classic: a telescopic fork up front and a steel swinging fork with a central shock strut at the rear. Spring travel measures 120 mm front and 90 mm rear (4.72" / 3.54"), tuned for a composed ride. The BMW R18 weight is 345 kg (760.59 lbs) fully fueled, so low-speed maneuvers require deliberate inputs, but once rolling it feels planted and predictable. Dimensions reinforce its presence—length 2440 mm, width with mirrors 964 mm, height excluding mirrors 1126 mm.
Braking is handled by a twin 300 mm front disc setup with four-piston fixed calipers and a single 300 mm rear disc with a four-piston fixed caliper. BMW Motorrad Integral ABS (partially integral) adds confidence when stopping a large cruiser on varied surfaces.
Chassis hardware is solid: a double-cradle steel frame with screwed-on underbeams, shaft final drive, and spoke wheel (front only). Rim sizes are 3.5" x 19" at the front and 5.0" x 16" at the rear, wearing 120/70 R19 and 180/65 B16 tires respectively. Electrical capacity is robust thanks to a 600 W permanent magnet generator and a 12 V / 26 Ah maintenance-free battery.
Practical touches include an approx. 16 l usable tank with an approx. 4 l reserve. Unladen weight fully fueled is 345 kg, with a max permitted weight of 560 kg and a max load (with standard equipment) of 215 kg.
Experienced riders who value a torque-first power delivery, classic boxer character, and the low-maintenance appeal of shaft drive will feel right at home. It’s a natural fit for relaxed daily rides and weekend cruising, where stability and style matter more than razor-sharp agility. Newer riders may find the combination of height-friendly ergonomics enticing, but the mass and torque suggest it’s best suited to those comfortable with heavyweight cruisers.
The 2024 BMW R18 specs paint a clear picture: massive torque at low rpm, a low 690 mm seat, and the planted feel of a 1731 mm wheelbase. Add in BMW Motorrad Integral ABS, strong four-piston brakes, and shaft drive, and you get a cruiser that blends tradition with dependable modern safety. Fuel consumption of 5.6 l/100km and a 16 l tank support unhurried, long rides.
On the flip side, the BMW R18 weight of 345 kg means it’s not a flickable backroad scalpel, and riders should respect its size in tight spaces. If you’re after a characterful heavyweight with classic engineering, stable manners, and authentic boxer thump, the R 18 is a compelling choice.
