’32 on a 32

A Fluke Ti32 thermal imager, using IR-Fusion® and SmartView® analysis and reporting software to blend visible and infrared images, reveals the unseen temperature changes that occur during a five-mile test ride of a classic motorcycle.

Brighter colors in these images usually mean warmer temperatures (as indicated by the temperature scale on the right side of each thermal image), but because different surfaces emit and reflect heat differently, more exact measurements require some interpretation. Visit the Fluke Thermal Imaging Training Center to learn more about using thermal images.

The fully restored 1932 Harley Davidson.


Before the test ride, with the engine at the ambient temperature.


Just fired up, the motorcycle quickly heats its exhaust pipes.


After the ride, the rear brake temperature has climbed.


The front brake appears to be running cooler than the rear, possibly because of better air flow.


The intake side of motor.


Infrared image reveals that the rear cylinder is hotter than the front cylinder.
