There are immense benefits to choosing a 4-stroke engine over a 2-stroke engine.
Buying a 4-Stroke Engine over a 2-Stroke means:
- More HP – Higher torque at lower RPMs.
- No need to mix oil with fuel – Less pollution and more convenient.
- Longer Life – Four-stroke engines tend to last longer, run cooler, and safely run for more extended periods.
- Quieter – 4-stroke engines make less noise than 2-stroke engines.
Fuel Costs for a 4-stroke bike
Consider a 4-cycle engine that can get far more than 100 miles per gallon. Now, let’s figure a hypothetical example. Let’s say fuel gets expensive, up to $3.00 a gallon, and you’re only getting the low end of 100 miles per gallon. So you’re looking at a low fuel cost of .03 per mile.
Most bike fuel tanks are 2-liters. Converting that to gallons, it’s approx .26 gallons or very close to a quarter gallon of fuel capacity. So having a full 2-liter gas tank works out to be over 25 miles of travel between refuels.
Not too bad, considering that some 4-stroke bike motor kits are capable of 35 MPH, your bike could go as fast as a small moped or scooter and keep up with traffic on many residential roads for pennies a mile. Well worth the engine’s cost, a cheap road or mountain bike, and a few hours of installation, in my opinion.
