Introduction: Dirt Bike/ Motorcycle

About: I'm an apprentice toolmaker based in Swindon, UK

this was my project i did for my college assignment. With me wanting to do something odd and different compared to the standard project which people were doing like altering the play station remote or modifying there computers.

I came up with the idea when i wanted something to use to get around the farm with which was also cheep and on a budget.

I also wanted to make the bike experimental by using box steel instead of conventional tubing. i also thought it would be easier to weld up with it being square.

Step 1: The Build

I started the build by playing around with what shapes to do to fit the engine and also what would work and look good

once i was happy i then tack welded it so any modification could be done quickly and easily.

i also added tobe on the inside of the frame to mount the engine onto.

Step 2: Adding the Wheels, Etc...

the wheels i used from a mountain bike which i got off eBay for £25.00 in Bristol

i then cut off what i didn't need then tied on the parts to get an ideas of what it would look like before welding it all together.

Step 3: Paint Job

now the frame is together and welded up i decided to paint the bike Saturn black as i though that color suited the bike with the grey seat which was from a center part of a rear seat in a jaguar which i got from the scrap yard

Step 4: Gearing

this was by far the most complex part of the build to make sure everything was in line to prevent the chain snapping or getting caught

Step 5: The Electrics

I decided to add some electrics to the bike which consisted of a horn and alarm just to make life harder for myself.

I built the circuit first on bread board then on strip board.

Step 6: Completion and Test Run

this the bike in action and completed photos

Enjoy =D

The bike in total cost £152.94 which is pretty cheep to be fair for what you would pay for a normal dirt bike.
