Positioned in Harley-Davidson's enduro - offroad motorcycle lineup, the 1970 Harley-Davidson Baja 100SR pairs a 98 cc (6 cu in) single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 12.6 HP (9.2 kW) at 8,000 rpm while maximum torque reaches 12 Nm (8.9 lb-ft). With a specific output of 128.6 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Baja 100SR measures 84 kg (185 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 865 mm (34.1 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 110 km/h (68 mph).
