Chassis Design:
Aluminum frame contributes to rigidity and precise handling. Rubber mounting of the engine reduces rider fatigue.
Instrumentation:
Digital LCD instrument cluster with tachometer, speedometer, odometer, trip meters, clock, and warning lights. Some models may have a lap timer or fuel level indicator.
ABS:
ABS (Anti-lock Braking System) was generally an optional feature on many Buell models, including potentially the 2005 Firebolt. Manual would specify if equipped.
Diagnostic Ports:
Likely equipped with a diagnostic connector for electronic troubleshooting using specialized tools or software.
Oil Change:
Typically every 2,500-5,000 miles or annually. Specific interval depends on riding conditions and Buell recommendations.
Belt Tension Check:
Regular checks recommended, typically every 2,500 miles. Belt replacement interval varies.
Spark Plug Replacement:
Check/replace per manual schedule, often around 5,000-10,000 miles.
Engine Oil Type:
Varies, but often a high-quality motorcycle-specific synthetic oil meeting Harley-Davidson or Buell specifications (e.g., SAE 20W-50 or SAE 10W-40). Refer to manual for precise grade.
Brake Fluid Type:
DOT 4 or DOT 5.1 hydraulic brake fluid.
Coolant Type:
