Harley-Davidson Motor Co. has announced that it has gone to a higher level of motorcycle production through its latest Project Rushmore motorcycle line.

Since July, the company, including its plant in Springettsbury Township, has been producing eight new 2014 Harley-Davidson models for the Project Rushmore line.

They are Road King, Street Glide, Street Glide Special, Electra Glide Ultra Classic, Ultra Limited, Tri Glide Ultra, CVO Ultra Limited and CVO Road King.

"From tip to tail, we have transformed these motorcycles - the power, style, comfort, control and a whole new world-class infotainment system were the key areas of focus," Jennifer Hoyer, company spokeswoman said in a statement.

This is the largest-scale new model launch in the 110-year history of Harley-Davidson, based in Milwaukee, according to the company.

Customers can order them now, Hoyer said.

The Project Rushmore motorcycle line is a result of Harley-Davidson's getting input from customers on how to improve their riding experiences, according to the company's news release.

The motorcycles feature production improvements in control, infotainment, feel and style.

For control, the riding machines pass faster, stop quicker and see farther at night. The motorcycles feature a new color-screen infotainment system that includes voice recognition and touchscreen for music, GPS navigation and phone system. There also is text-to-speech technology.

There also are wide and deep passenger seats with new back and arm rests; large Tour-Pak and saddlebags; light aluminum wheels; and intuitive hand control switches, according to the company.

Project Rushmore is an expression of Harley-Davidson's relationship with its customers and a shared passion for motorcycle riding, said Mark-Hans Richer, the company's senior vice president and chief marketing officer.

"It's resulted in some outstanding innovations, but from day one we've been focused on taking the total rider and passenger experience to the next level," he said. "(We've) been saying that we ride with you. Project Rushmore elevates that devotion to a higher level."

Harley-Davidson also announced updates and improvements on its other motorcycles, including the restyled Fat Bob with black replacing chrome; the availability of anti-lock brakes on all five 2014 Sportster models; and the new Street Glide Special, a fully-loaded version of the Touring model.
