Okay, if you wanted to build a bigger bike (maybe motorcycle or moped classification) which motor would you pick and what kinda setup would you do? I am just curious about these two motors, which seem to be the most popular mainstream big motors.
It seems the Predator 212cc is a little more popular than the Lifan but both are possible to mount on a bike. The Predator is half the price of the cheapest Lifan (manual) and there are kits specifically designed for the 212cc Predator. For the Lifan you will have to create mounting bolt holes yourself. The Lifan is designed for moped/small motorcycle use while the Predator is a general use engine. The Lifan also has 4 gears in its internal transmission while the Predator does not and has a higher RPM red line. Also, number wise, I couldn't find specifics about the Predator such as maximum net power @ its maximum RPM 3800. I know most people remove the governor on their Predators but I am not able to find any information.
Last point, while the Lifan is double the price of the Predator, remember that it does have an internal 4 gear transmission. To get the same for a Predator, you will have to buy a jackshaft kit which at the end of the day kinda balances out the price for both.
Lifan : ~$250 (manual)
Displacement : 123.77cc
Compression ratio : 9.5:1
Max. Net Power : 8.5 Kw DIN @ 9500 rpm
Rated Power : 6.5 Kw @ 7500 rpm
Min. Torque : at least 8.8 Nm @ 5500 rpm
Predator : $120
Displacement : 212cc
Compression ratio : ????
Max. Net Power : ????
Rated Power : ???? 4.84 Kw (6.5 mechanical hp) @ 3800 rpm???
Max. Torque : 10.98 Nm @ 2500 rpm
