The BMW R12 is a motorcycle manufactured by BMW Motorrad, which is offered as the cruiser motorcycle R12 and as the roadster R12 nineT (with the English pronunciation ['naɪnti]). The name "R12", which had already been used by BMW for a motorcycle model from the 1930s, was re-protected by the manufacturer in 2021 in Germany and internationally in 2022.^[1] Both models were presented at the end of November 2023 as the successor to the R nineT introduced ten years earlier.^[2]^[3]

Construction

Both R12 models have an air and oil-cooled four-valve two-cylinder engine with 1170 cm³ displacement^[2] and a balance shaft. The stroke is 73 mm,^[4] the compression ratio is 12.0:1.^[1] It has an engine drag torque control and was tuned differently for the two models: the R 12 has an output of 70 kW at 6500 rpm and a maximum torque of 110 Nm at 6000 rpm,^[2] the nineT has an output of 80 kW at 7000 rpm and a torque of 115 Nm at 6500 rpm.^[5] The engine of both models can be throttled to 35 kW at 5250 rpm;^[2] then the torque is 98 Nm at 3000 rpm.^[6] An airbox is installed under the seat.^[1] The machine can be started with a radio key (Keyless Ride).^[2] Similar to the R18, the R12 offers the driving modes Roll (standard) and Rock with a more direct response when turning the throttle;^[4] the nineT has three settings: Road, Rain and Dynamic.^[5] The engine meets the Euro 5+ emissions requirements.^[5] The steel tank holds 14 liters, the aluminum tank of the nineT 16 liters.^[2] According to the World Motorcycle Test Cycle (WMTC), the consumption of both models is 5.1 liters/100 km.^[4]^[6]

Chassis

The R12 has a steel tubular space frame with an aluminum swing arm at the rear. At the front, the motorcycle has a 45 mm upside-down fork, which is only adjustable on the nineT model. The suspension travel on the R 12 is 90 mm front and rear, on the nineT it is 30 mm more. The models also differ in tire size: the R 12 has a 19-inch wheel at the front and a 16-inch wheel at the rear, while the R 12 nineT has two 17-inch wheels. This gives the nineT a 41 mm higher seat height of 795 mm. Cast aluminum is used for the wheels, and spoked wheels are available on request; the tires are tubeless, which also saves weight.^[2] The brakes are supported by ABS with lean angle consideration (partially integrated ABS).^[2] The handbrake lever operates the front and rear brakes simultaneously.^[5]

Other

In addition to other special equipment and accessories, cornering lights are offered. A tachometer (standard equipment on the nineT) can be added to the R 12. Both models can also be equipped with a digital instrument cluster (display with a diagonal of 3.5 inches).^[2]
