The engines from all three bikes featured an air-based cooling system.

Weight

• Despite their different engine sizes, the FLH 1200 Electra Glide and FLH 1340 Electra Glide both had a gross weight (the mass of the bike with full oil and fuel tanks) of 760.6 pounds. However, the FLHC 1340 Electra Glide Classic was slightly more massive, weighing in at 767.2 pounds.
  
  

Speed

Fuel Capacity

• Riders who chose the FLH 1200 over either of the FLH 1340 models may not have had as much speed or horsepower, but they didn't have to stop at the gas station as often. The FLH 1200's 6.6-gallon fuel capacity was over 25% larger than the 5.0-gallon capacity of the FLH 1340 bikes.
