Built around Big Bear Choppers's custom - cruiser motorcycle platform, the 2009 Big Bear Choppers Devil´s Advocate ProStreet 100 EFI relies on a 1638.8 cc (100 cu in) v2, four-stroke powerplant. In factory specification, peak output is rated at 95 HP (69.3 kW) while maximum torque reaches 149.2 Nm (110 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 58 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Devil´s Advocate ProStreet 100 EFI measures 317.5 kg (700 lbs) dry, translating to a power-to-weight ratio of 0.3 HP/kg (3.34 kg per horsepower). Rider ergonomics and chassis geometry center around a 584 mm (23 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 2,108 mm (83 in) wheelbase engineered for planted straight-line stability. The 22.23-liter (5.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
