Safety Ratings:
Motorcycles typically do not receive NHTSA or Euro NCAP ratings; safety is primarily judged by design and component quality.
Braking System:
Front: Single disc brake with dual-piston caliper. Rear: Disc brake with single-piston caliper. ABS was not typically offered on this model.
Lighting:
Halogen headlight, taillight, brake light, turn signals.
Tires:
Sportbike-oriented tire sizes. Front: 110/70-17. Rear: 130/70-17 or 140/70-17. Specifics in manual.
Infotainment System:
None. This is a 1990s era sportbike focused on mechanicals and performance.
Assistance Features:
None. Focus is on rider input and basic functionality.
Connectivity Features:
None.
Gauge Cluster:
Analog speedometer, tachometer, odometer, trip meter, fuel gauge (if equipped), warning lights.
Oil Change Interval:
Typically every 3,000-5,000 km or 6-12 months, whichever comes first. Manual will provide precise intervals.
Spark Plug Replacement:
Every 10,000-15,000 km. Manual will specify plug type and gap.
Chain Adjustment:
Check and adjust every 1,000-2,000 km. Manual will detail slack specification.
