Valve Train:
SOHC (Single Overhead Camshaft), 4 valves
Horsepower:
Approximately 15-16 HP (at the crank, subject to specific tuning and market regulations).
Torque:
Approximately 16-17 Nm (at the crank).
Fuel Delivery:
Electronic Fuel Injection (EFI)
Fuel Type:
Unleaded gasoline
Crash Protection:
Notable for its enclosed 'safety cell' offering significantly more protection than a traditional scooter or motorcycle.
Braking System:
ABS (Anti-lock Braking System) was a key feature, particularly for the front wheel. Dual disc front, single disc rear.
Lighting:
Headlight, taillight, brake lights, turn signals (likely halogen or early LED depending on market). Reflectors integrated into bodywork.
Occupant Restraint:
Seatbelt integrated into the safety cell. Roll-over protection structure within the cage.
Windscreen:
Large, integrated windscreen providing significant wind protection.
Oil Change:
Typically every 5,000 - 7,500 km or annually, depending on usage (specific interval in manual).
Air Filter Replacement:
Every 10,000 - 15,000 km, or as indicated by performance decrease (specific interval in manual).
Spark Plug Replacement:
Every 20,000 - 30,000 km, depending on spark plug type (specific interval in manual).
Cvt Belt Inspection:
Inspection typically around 10,000-15,000 km, replacement as needed based on wear.
Engine Oil Type:
Synthetic SAE 5W-40 or 10W-40 motorcycle-specific oil (refer to manual for exact BMW specification).
Engine Oil Capacity:
Approximately 1.4 - 1.6 liters (check manual for exact capacity).
Coolant Type:
Ethylene glycol-based coolant, BMW approved (refer to manual for specific BMW part number/specification).
Brake Fluid Type:
DOT 4 brake fluid (refer to manual for specific BMW specification).
Electrical Gremlins:
Age-related issues with wiring harness connections and module failures can occur.
Cvt Wear:
The CVT belt and clutch components can wear over time, affecting performance and requiring replacement.
ABS Sensor Issues:
ABS sensors and wiring can be susceptible to damage or corrosion, impacting ABS functionality.
Water Ingress:
The unique bodywork design can sometimes lead to water ingress in certain electrical connectors if seals degrade.
Manufacturer:
BMW Motorrad, a division of BMW AG, known for its premium motorcycles and automotive engineering.
Predecessors:
No direct predecessor in this unique segment. Represents BMW's exploration into alternative personal mobility solutions.
Successors:
While the C1 concept was unique, BMW continued its scooter development with the later C series (C600 Sport, C650 GT).
Manufacturing Location:
Primarily manufactured in Italy by an Italian subsidiary or partner of BMW, taking advantage of existing scooter manufacturing expertise.
Production Span:
Covered a relatively short period, 2000-2003, indicating it was a niche product.
