What is the 2002 harley sportster throttle grip size ?

The throttle grip size for a 2002 Harley-Davidson Sportster is typically designed to fit 1-inch (25.4 mm) handlebars, which is the standard handlebar diameter for most Harley-Davidson motorcycles of that era.

The throttle grip is directly in contact with the handlebar. 

If you're planning to replace or upgrade the grips, make sure they are specified for 1-inch handlebars and compatible with a Harley-Davidson throttle tube.
