The 4-stroke engines have proven to be more reliable and durable than the 2-stroke engines. Chain Transmission and Pull Start provides much easier control and handling for little kids and gives the rider the great convenience in the event of a stall. Additionally with the 4-stroke you get：
More torque:In general, 4 stroke engines always make extra torque than 2 stroke engine at low RPM.More fuel efficiency:4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes.EPA Approved:As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.More durability:We all know that more the engine runs, quicker it wears out. 2 stroke engines are designed for high RPM. If an engine can go for 10000 rpm’s before it wears out; a 4 stroke engine with 100 rpm will run for 100 minutes than the other 2 stroke engine which has a higher rpm of 500 & will run for only 20 minutes.No extra addition of oil:Only the moving parts need lubrication intermediately. No extra oil or lubricant is added to fuel.
