The Sidewinder Plus
Independent fronts, monoshock in the rear...
Independent front & monoshocks rear suspension gives this beast awesome handling over rough tracks at high speeds. Designed for 350cc - 650cc single cylinder enduro or motocross bike motors. Tops 120kph with 0 - 100kph in 6.5 seconds.
Nimble and compact...
The Sidewinder is the most nimble and compact of The Edge Products range of off road buggies.
Side mounted motor...
Power comes from a trail or motocross bike motor mounted alongside the driver. Front Suspension is Single ‘A’ Arm with coilover shock absorbers. Rear Suspension is a durable swingarm with solid axle and single coilover mono-shock.
Precise control on rough terrain..
Drive is chain direct from the motor to the axle, with the motor’s sprocket positioned inline with the suspension arm pivot point for reliable and precise chain tension. Steering is via a car-type rack & pinion to eliminate bump-steer and give precise control on rough terrain.
Easy & Comprehensive Plans
The Sidewinder Plus plans is comprehensive with over 90 pages including lots of 3D images. They can be purchased in a printed book or in digital form ready for immediate download (and at a discounted price).
These detail every chassis & suspension part that needs to be made along with parts lists, nuts & bolts lists & material lists. Laid out in 3D views with 2D dimensioned detailed drawings the Sidewinder Plus plans detail the complete chassis, front & rear suspension, brakes, pedals, all brackets, fuel tank, floor pan, roof plate, nose plate, bonnet, bulkhead plate, engine bash plate, complete steering including rack mount & steering column & gearshift setup. In fact, every single part that needs to be made.
The Sidewinder plans explain the chassis construction in a "step by step" format starting with the base frame & building the chassis from the ground up to make construction easier for the home builder. Suspension arms & components are broken down into their individual parts for ease of manufacture.

Suitable Engine Types
The Sidewinder design uses a motorcycle motor mounted along side the driver, generally on the right-hand side of the chassis.
The side-mounted motor's output sprocket lines up with the rear suspension swing arm pivot point. This means that when the suspension arm arcs up & down the chain will keep a constant tension.
The weight of the motor is counterbalanced by the fuel tank on the opposite side - but a motor which is too heavy or too wide can still upset the Sidewinder's handling.
With this in mind a single cylinder motor is the best choice.
But where to from here?
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. Trail bikes usually have the bonus of electric start - it's no fun needing to unbuckle from the driver harness and climb out every time the engine needs starting!
Bikes like the Kawasaki KLR650, Suzuki DR650 and Honda XR650 are no-fuss workhorses which will haul all day long without hitting the service budget hard.
More advanced engines such as the KTM 690-family up the horsepower further for a true off-road weapon.
Modern high-strung 450cc motocross motors are also capable of wheel-spinning performance in the Sidewinder, such as the Honda CRF450, Yamaha WR450F and Kawasaki KX450F.
Finally, don't forget ATV / quad-bike powerplants like a Yamaha Raptor 660 which often include a reverse gear.
Kawasaki KLR650 Engine
Looking for something exotic? Two stroke motocross 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.
Some of the best models (we believe) of motorcycle engine are as follows:
660 Yamaha Raptor
690 KTM Enduro
Double A-Arm Front Suspension Upgrade
The Sidewinder Plus can be upgraded to use the Piranha III Double A-Arm front suspension. See here for further information and to purchase plans and parts.
