This is a Harley Davidson based street style drag bike. I used a thinner wall than I would use with chromoly because of the additional strength and durability of the Docol material thus saving weight. We purchase our Docol Tube R8 from AED Motorsports.
I like the Docol for the potential weight savings, added durability, additional welding options and the clean surface finish ( Does not need buffed off before use). The area around the welds seem to be a lot stronger than the old material allowing us to use more mounting options for drivetrain and accessories. Overall this stuff is better suited to our application.
