Drag style handlebars are a great fit for motorcycles running taller risers.  For an aggressive feel, trim a few inches off each end and narrow them up a bit.  These are 1" diameter bars and available without dimpled for pre-1982 Harley Davidson controls or with dimpled for 1982 and later Harley models. Chrome-plated.

Measurements:

• 1” diameter
• 26” wide
