MOTORIZED REAR END
MOTORIZED REAR END is a custom rear end that fits our drift trikes that have
removable rear ends. MOTORIZED REAR END uses a 6.5hp go kart engine to
make your regular drift trike into a motorized one. This is a simple straight forward
build that uses common parts that are regularly available. We have drawn this rear
end with a 40mm go kart rear axle but we have also included measurements and
instructions if you choose to use other popular go kart axle sizes like 1 ¼” and 1”
(25mm).
SPECIFCATIONS
Frame: Mild steel RHS
Brakes: Go kart rear disc brake hub and caliper. Must be 190mm in diameter for
ground clearance.
Rear wheels: Front go kart wheels.
Rear axle: Go kart 1”, 1 ¼” or 40mm rear axle.
Sprocket: Go kart sprocket and hub. Must be 65 tooth or less for ground clearance.
Engine: 6.5hp four stroke go kart engine. An engine based off a Honda GX200 is
what will work best. These engines are widely available due to them being copied
from many different Chinese engine manufacturers.
Clutch: Go kart centrifugal clutch to suit engine.
Chain guard: Custom 1.6mm sheet metal guard. We have included fabrication plans
for this.
Bearings: Pillow block bearings. If using 40mm rear axle then two UPC 208 – 40mm
bearings needed. If using 1 ¼” rear axle two UPC 206 – 20 bearings needed. If using
25mm (1”) rear axle then two UPC 205 – 25mm bearing needed.

SAFETY
IMPORTANT: PLEASE READ THE FOLLOWING BEFORE RIDING
DRIFT TRIKE BUILD PLANS wish to advise in the intrust of your enjoyment, some
safety features which will enable you to enjoy riding your trike and minimise the risks
to yourself and others.
HELMET
Always wear a good crash helmet, a full face helmet offers more protection than an
open face. Remember to buckle up the chin strap.
CLOTHING
Always wear paints, long sleeved shirts and clothed in foot wear.
PROTECTIVE GEAR
It is advisable to wear knee and elbow pads to minimise injury if and accident was to
occur. Gloves are also and essential part of protective gear.
DRINKING, DRUGS AND RIDING
DO NOT consume alcohol and ride any type of trike, bike or vehicle. Drinking and
riding is dangerous to both yourself and others. The nature of drift trike riding is
demanding and unpredictable so you need to be alert and focused on what you are
doing at all times. Drugs and alcohol dull your senses and concentration.
SHARP OBJECTS
Make sure the frame or any parts of the drift trike that you have fabricated is to
design specs and all sharp edges and burrs have been removed.
BRAKES
Good brakes are essential. Braking is relative to speed; the faster you go, the better
your brakes should be. Always maintain your brakes so that they are always in good
working order.
STEERING
Steering is an important safety area, without it you have lost control. Always make
sure that steering components are in good condition and check for loose bolts/parts.
The more responsible you are, the better it will be for all of us and the better an
image for the sport of trike drifting you will create, guaranteeing for all of us
acceptance and respect from the general public.

PLANS have no control over how or where an individual chooses to use their drift
trike.

TOOLS AND EQUIPMENT
Some basic equipment will be needed to fabricate the drift trike frame. Here is a list
of basic tools and equipment needed.
WELDER
A ‘Mig Welder’ is the most preferred as it can be used by most novice welders with
the minimum of experience. Another type of welder is the ‘Arc Welder’, this can be
used just as readily but needing more skill and practice to produce clean tidy welds.
Other forms of welding suitable for construction are ‘Tig’ and ‘Gas’ welding (brazing).
The form of welding used depends on what your personally have available and what
your skills are best suited to.
CUT OFF SAW
Ether a grinding type ‘Drop Saw’ or a ‘Power Hacksaw’, or ‘Bandsaw’ may be used.
If either of these are not available a ‘Hand Hacksaw or ‘Angle Grinder’ may be used
with a sturdy vice.
DRILL PRESS
A drill press of 5/8” (16mm) capacity is the more suitable but you may use a hand
power drill either in a drill press stand or on its own.
SQUARES
A large fabrication square, a one meter rule and protractor bevel for marking out and
setting up the frame and angles will be required. A tape measure for measuring tube
lengths.
GENERAL HAND TOOLS
Adjustable spanners, pliers, angle grinders (4” or 5”), socket set, hand files, bench
vice and a sturdy bench will all come in handy.

TIPS ON CONSTUCTING
BEFORE BUYING PARTS DECIDE ON THE FOLLOWING
There are three popular sized rear go kart axles that you can choose from for this
build (25mm or 1”, 1 ¼” and 40mm). All axles should be 1050mm long. A 25mm / 1”
axle will be lighter and cheaper but a 40mm axle will be stronger. Parts so suit a 1 ¼”
might be more widely available and cheaper in your area. A 25mm / 1” axle will give
you a little more ground clearance than a 1 ¼” and 40mm. So before buying a
certain size axle weigh up the pro’s and con’s of each size. Parts needed to suit your
axle size are: AXLE, Pillow block bearings x 2, disc brake hub, sprocket hub and
wheel hub x 2. Some stores sell all this in a package, this is usually the cheapest
option. Make sure you shop around for best price.
PURCHASE OF PARTS
Purchase of second hand parts will bring the cost of the build down considerably.
The design of this trike incorporates widely available parts that can be easily found
from many suppliers.
WHEELS
Front go kart wheels and tyres are used in this design because they are easily found
and second hand items are usually sold cheap or just thrown in the trash. Wheels
with a hub to suit your axle size choice.
GEOMETRY
Take extra time and care to ensure all the steering components are true and square
before fully welding.
BRAKES
You will need a go kart rear disc brake, disc brake caliper, brake leaver and a disc
hub to suit you axle choice. We recommend using a 190mm diameter disc brake,
any larger than this will give you very little ground clearance.
8
SPROCKET
A go kart rear sprocket and hub to suit you axle choice will be needed. A 65 tooth
sprocket is the largest sprocket you will be able to use to still have enough ground
clearance. We recommend getting a sprocket to suit a #35 chain.
CLUTCH
Buy a clutch that suits your engine and sprocket choice. We recommend buying a
clutch, sprocket and chain together in a package.
GEARING AND DRIVE RAITO
There is a lot of information on the internet about drift trike gear ratios. There is no 1
size fits all answer when considering gear ratio. If your small and light you might get
away with a taller gear ratio than a larger overweight bloke. We recommend doing a
little research into pro’s and con’s of gearing before buying your rear sprocket and
clutch/sprocket. In saying that something like a 1 to 5 or 1 to 6 ratio is usually a good
fit. So shop for something like a 10 and 60 tooth or a 12 and 60 tooth package.
ENGINE
A quick eBay search for 6.5hp engine will come up with hundreds of engines. Some
will be better quality than others. Some will have an electric start. Some might have a
2 to 1 drive ratio. Some will come with a package including throttle controls,
exhausts, mounting plates and other extra goodies. We recommend shopping
around and buying a mid price ranged engine off a seller with a good returns policy.
The Honda GX200 OHV four stroke engine that has been copied many times over by
Chinese manufactures is a good robust engine that makes for an excellent go kart
and drift trike engine.
