BMW C1 redefines mobility
With the C1 the BMW Group introduced a vehicle concept that redefines
urban mobility.The C1 combines the typical comfort and safety features
of an automobile with the driving characteristics and environmental
advantages of a 2-wheel vehicle. Following its market launch in spring
2000, the C1 has attracted attention in many southern and western
European countries.

Engine and emission control
The C1 is equipped with a single-cylinder, four-stroke
engine (125 ccm) based on a design developed by
Bombardier-Rotax.This engine features an innovative
electronic engine management system with a combined
microprocessor timing system for ignition, fuel injection,
oxygen sensor, and idle speed regulation. Like all BMW
two-wheel vehicles, the C1 concept was developed to
include a regulated 3-way catalytic converter for reduced
emissions.This results in a CO 2 output of less than
64 grams per kilometer. At a constant speed of 90 km/h,
fuel economy averages over 2.9 liters per 100 km.
Exhaust system
The exhaust system was adapted for the 3-way catalytic
converter and is designed to comply with noise level
restrictions (77 dB, A) specified for motorcycles in this
class.
Safety
The C1 safety concept essentially includes five modules:
The crash deformation shroud above the front wheel, the
BMWTelelever as an additional energy absorbing assembly,
the main frame that serves as a safety cell for the driver,
a special seat with head restraints, and a 3-point/2-point
seat belt. BMW C1 drivers are not legally required to wear
a helmet in many European countries.
