The Sidewinder design uses a motorcycle motor mounted along side the driver, generally on the right side of the chassis.
The reason for the side mounted design is to have the motors output sprocket line up with the rear suspension swing arm pivot point. This means that when the suspension arm arcs up & down the chain will remain a constant tension.
A side mounted motor will un-balance a buggy if the motor is either too heavy or the motor is positioned too far away from the chassis centre line.
With this in mind a single cylinder motor is the lightest design.
So what type of single cylinder motor suits the Sidewinder best?
Four stroke single cylinder trail bike motors are the most user friendly in terms of good power to weight ratio & lots of low end torque.
Most modern trail bike motors are also fitted with electric start, this is a big bonus to the driver as once you are strapped into your buggy the last thing you want to do is un-buckle & climb out to kick the motor over again.
Two stroke Moto X bike motors are very powerful & light weight. This type of motor in 500cc form produces a very powerful buggy, but the negative side is the intense vibration, lack of electric start & the temperamental nature of the two stroke motor.
