Factory racing colours

The National Motorcycle Museum documents the first XR750’s orange and black bodywork. Individual race teams used their own numbers and liveries.

  • BlackContrasting bodywork and frame

Screen swatches are a colouring guide rather than exact paint matches.

In the photographs

The gallery consistently shows orange-red tanks and tails with black seats and chassis, plus white panels on some racers. The first three views are a 1980 alloy-engine XR750, ten years later than the book model. The remaining race bikes have unconfirmed years and team specifications. Their graphics and numbers are not a fixed 1970 factory template.

  • Orange-red
  • Black
  • White number panels

Visual colour guide only. These are not additional factory paint options.

In the coloured example

The orange tail fits the XR750 racing colour theme. The cream tank inset and pale number plates are creative choices; the museum documents orange and black bodywork for the early XR750.

04 / Useful tips

Make the details count.

01

Leave the number plates and shield emblem blank.

02

Use alternating light and dark strokes on the V-twin cooling fins.
