GRID STEP. You can print out the base construction lines and start drawing on tracing paper, or you can draw the grid layout yourself using the following steps.1) Draw a rectangle that will define the conditional proportions and boundaries of the chosen drawing. 2) From the middle of the rectangle, draw one vertical and one horizontal line equally dividing the shape. 3) Draw another horizontal line equally dividing the upper half of the rectangle. Similarly, draw a horizontal line equally dividing the bottom half of the rectangle. 4) Draw a vertical line equally dividing the left half of the rectangle. Similarly, draw a vertical line equally dividing the right half of the rectangle.

STEP 1. Mark off the width and height of the chopper motorbike. Draw two ovals for wheels and a slant line for a telescopic fork.

STEP 2. Define, with two ovals, the wheel rims and add the general shape of the body.

STEP 4. Outline the telescopic fork, engine and exhaust pipes. Add the shape for a chopper motorbike seat.

STEP 5. Draw the general shapes of the engine and handlebars. Show the motorbike frame.

STEP 6. Add more details.

STEP 7. Work on the figure, paying special attention to parts and components.

STEP 8. Contour the chopper motorbike, trying to vary the thickness and blackness of the line. Add more details and trees. Erase all guidelines.
