What Is a Good Size Engine for a Go-kart?

Best Go-Kart Engines

Small block engines produce enough power for most go-karts. But some use over 20 hp engines. These are too much for most drivers. So 13-16 hp engines are best for more power.

  • Match engine to driver’s skill level.
  • Kids require 5-7 hp engines. Adults prefer 13-16 hp engines.

Engine Types and Top Options

2-stroke engines excel in sprint karting due to quick acceleration, while 4-stroke engines offer better fuel efficiency for endurance karting. Top engine options include:

  • Predator 212cc
  • DuroMax XP7HPE 208cc
  • AlphaWorks 212cc
  • XtremepowerUS 212cc

Engine Tuning and Maintenance

Consult mechanics for assistance in tuning the engine and chassis to optimize power delivery, grip, and stability. Tuning is an ongoing process to adjust to changing conditions.

  • Torque converters are recommended for heavier karts.
  • Centrifugal clutches maintain gear ratios and can handle up to 50 hp.
  • Ensure the belt is tight on the pulley for proper function.

Go-Kart Rental Engines

Rental go-karts typically feature engines ranging from 150-250cc with power outputs between 5-16 hp. Some of the most powerful rental karts may have engines with 20-48 hp ratings. Horizontal shaft engines are commonly used in go-karts, with a 3/4" shaft size being standard.
