   A SOLID FOUNDATION: THE NEW HARLEY-DAVIDSON TOURING CHASSIS
   Enhanced Comfort, Increased Capacity and Refined Maneuverability for the Road

   MILWAUKEE (July 22, 2008) – The new chassis that underpins the 2009 Touring motorcycles from Harley-Davidson improves comfort and functionality of these legendary machines, while preserving the timeless character that makes a Harley-Davidson Touring bike the King of the American road.

   The Touring frame, triple clamps, swingarm, engine mounts, exhaust system, rear fender, wheels and tires have been redesigned, and together provide the foundation for what are truly all-new motorcycles. Key styling elements – including the front end, fuel tank, saddlebags and Tour-Pak – are essentially unchanged, so that these Touring models are visually similar to those distinctive motorcycles that precede them. Ride quality remains smooth, while maneuverability is precise and responsive.

   The Frame
   Forming the core of the 2009 Touring chassis is a new frame with a single-spar, rigid backbone designed to sustain the demands of long-haul touring riders and today’s powerful engines. The new frame provides a strong foundation that supports a 70 pound increase in carrying capacity. The storage compartments have a 15-pound increase in rated cargo capacity (five pounds per saddlebag, and five pounds in the Tour-Pak).

   The frame is engineered to be manufactured with the latest coordinated motion robotic welding process, which offers outstanding dimensional accuracy and weld quality. The frame design results in a 50 percent reduction in parts, and a 50 percent reduction in the total length of welds. T-studs have been eliminated, and the components of the new frame are joined with cast and forged node-tube joints.

   A separate bolt-on tail section isolates the main frame from the tail frame, providing better quality-control during manufacturing and more product-design flexibility. The new tail section improves the fit-and-finish of the rear area of the motorcycle through more-precise alignment of the rear fender over the rear wheel.

   A new swingarm is formed with a two-piece, deep-drawn shell with a forged pivot section. The new swingarm contributes significantly to the overall system.

   The engine-isolation system has also been revised, resulting in reduced engine and vehicle vibration at idle speed. The new system replaces a single front isolator with twin front isolators with a single tie link. The front and rear mounts are designed to provide optimal balance between stiffness and isolation, and are intended to be very durable. Finally, new asymmetric snubbers provide improved control of the clearance between the engine and frame during extreme bump events.

   Wheels, Tires and Suspension
   A new wheel-and-tire combination plays a key role in the responsive performance of the 2009 Touring chassis. Front wheel diameter is increased to 17 inches from 16 inches (except for the Road King Classic, which has 16-inch Laced chrome steel wheels front and rear), while the width of the 16-inch rear wheel is increased to five inches from three inches. New 28-spoke cast aluminum wheels were designed using finite element analysis for maximal stiffness with minimal weight. The Street Glide has restyled Slotted Disc cast aluminum wheels that have also been engineered for maximum stiffness with minimal weight.

   All 2009 Touring models will be equipped with new Dunlop D407 Multi-Tread rear tires designed specifically for the new Harley-Davidson Touring chassis. The construction of the tires and the distribution of a longer life center tread compound and more aggressive shoulder compound enhance straight line performance and will deliver up to 25 percent more rear-tire tread life than the previous tire. The wider rear wheel accommodates a new 180/65-16 rear tire that is wider and has a lower aspect ratio than the MU85B16 tire it replaces. The new rear tire size contributes to the increase in cargo capacity. The new front tire, a 130/80-17, also has a lower aspect ratio for a more modern look and responsive handling. Front and rear suspension has been recalibrated to match the dynamics of the new chassis, wheels and tires. Steering head rake and fork angle are unchanged at 26 degrees and 29.25 degrees respectively, but trail has been increased by 0.5 inch to 6.9 inches. Wheelbase is increased by .556 inches, to 63.54 inches.

   Powertrain
   All 2009 Touring models are powered by the Twin Cam 96 V-Twin engine with Electronic Throttle Control (ETC) mated to the 6-speed Cruise Drive transmission. A new one-piece welded exhaust header features a 2-into-1-into-2 design and features new routing to enhance rider and passenger comfort. On models so equipped, the exhaust catalyst is located in the collector. The rear pipe is restyled and now curves forward of the transmission. A new single-piece front exhaust shield replaces the previous two-piece shield and eliminates a gap that exposed the exhaust pipe on the previous exhaust system.

   Acceleration performance is improved on all 2009 Touring models due to a lower final drive ratio, as a 68-tooth rear sprocket replaces the previous 66-tooth sprocket. The Isolated Drive System has been redesigned, and the compensator is now integrated into the rear wheel hub, eliminating the bolt-on bowl for more integrated design.

   Styling, Comfort and Convenience
   The increase in wheelbase allowed the saddlebags to be moved rearward a corresponding distance (.556 inches) to increase passenger legroom in front of the saddlebags. The elimination of the left-rear exhaust pipe, and the new routing of the right-rear exhaust pipe, reduces the heat exposure to the rider’s thighs and the passenger’s calves.

   The rear fender has been re-shaped to accommodate the new 180 mm rear tire, and is also designed to work with 18-inch custom rear wheels from Harley-Davidson Genuine Motor Accessories. On models not equipped with a Tour-Pak, the license plate has been relocated below the tail light and is illuminated by an LED located in an eyebrow on the turn signal lightbar, except on the Road King Classic. Finally, the rear “hoop” over the fender has been eliminated from models not equipped with a Tour-Pak. The combination of these elements results in a striking new look to the rear end, with perfect proportions that are especially evident on Touring models that are not equipped with the Tour-Pak.

   The new Tour-Pak support rack has no holes in the tubes for Tour-Pak attachment. The new design uses fewer fasteners and hardware, and makes it easier to adjust the Tour-Pak fore and aft for passenger comfort. Tour-Pak capacity is increased by five pounds. Saddlebag capacity is increased by five pounds per side.

   Shorty dual antennas replace the previous whip antennas. With no loss of performance, both the radio and CB antennas now clear a seven-foot garage door.

   A new LED rear-fender tip light on the Electra Glide Classic and Ultra Classic Electra Glide is brighter and more attractive than the incandescent bulb it replaces.

   The revised exhaust routing and other new features combine to deliver comfort for the long haul in a variety of environments.
