TECHNOLOGY ENRICHES THE
HARLEY-DAVIDSON ADVENTURE TOURING EXPERIENCE

Pan America 1250 Special with adaptive seat height and semi-active chassis

With the models Pan America 1250 and Pan America 1250 Special presented Harley-Davidson two brand new adventure touring bikes. The company has mobilized all its engineering resources to equip the new models with state-of-the-art technology that enriches the riding experience.

Semi-active suspension

The Pan America 1250 Special features electronically adjustable semi-active suspension at the front and rear. Based on data stream from the vehicle sensors, this suspension automatically adjusts the damping to the ground conditions and riding activity. The semi-active suspension components are from Showa, while the control software is from Harley-Davidson itself.

• The suspension travel is 191 mm at the front and rear.
• The front fork is a Showaa BFF (Balance Free Forks) upside-down fork with a 47-millimeter stanchion diameter and semi-active damping control.
• The rear suspension element is a Showa BFRC (Balanced Free Rear Cushion-lite) central shock absorber with electronically controlled preload and semi-active damping control. It supports the swing arm against the rear frame via a progressive lever system. This progressive system ensures a high degree of directional stability and riding comfort on the road, as well as impressive off-road handling characteristics.
• The Vehicle Loading Control System registers the weight of the driver, passenger, and luggage and automatically adjusts the spring preload of the rear shock absorber.
• The semi-active suspension reacts to suspension compression, driving speed, vertical acceleration of the motorcycle, lean angle and the speed at which it changes, as well as the engine load specified by the rider on the throttle grip and any braking forces, in order to maintain the preselected comfort level. The control is dependent on the selected riding mode.
• The semi-active suspension has five pre-programmed profiles that are incorporated into each driving mode program:
• Comfort: maximizes driving comfort with softer damping and comfortably absorbs road irregularities.
• Balanced: balanced ratio of comfort and stability for general driving tasks.
• Sport: maximum directional stability with firmer damping for an engaging driving style.
• off-road Soft: Reduced damping at the beginning of the compression phase absorbs hard impacts even more efficiently and at the same time minimizes handlebar bumps. Ideal for forest trails, washboard tracks and rocky terrain.
• Off-Road Firm: increased damping at the beginning of the compression phase for sporty driving or when more even suspension is desired. Ideal for soft or clayey soils.
• The profile of the semi-active suspension cannot be changed within a pre-programmed driving mode. However, a preferred suspension profile can also be saved in the freely programmable custom driving modes.

The Automatic chassis lowering (Adaptive Ride Height, ARH) is available as an option for the Pan America 1250 Special. Harley-Davidson is the first motorcycle manufacturer worldwide to offer this new technology. The chassis is automatically lowered when the bike is stopped and raised to the optimal position for riding when the bike is started. This allows the rider to comfortably mount the Pan America 1250 Special while stationary and have secure ground contact with their feet. The lowering range is 25 to 50 millimeters, depending on the automatically adjusted spring preload on the rear wheel.

• Suspension travel, lean angle, ground clearance, and ride comfort remain unaffected while driving.
• The automatic chassis lowering system offers four selectable modes:
• mode CarThe system automatically sets the lowering speed based on the braking force in order to fully lower the seat height in good time when stopping.
• Short Delay and Long Delay modes: In these modes, the lowering is delayed to keep the seat height high at low speeds, such as when driving slowly in a parking lot.
• Locked mode: Automatic lowering of the seat height is deactivated. This mode is intended, for example, for tall riders who do not want the seat to lower when stationary, or for off-road riding at low speeds.

Driver assistance systems – RDRS Safety Enhancements

The Pan America 1250 and Pan America 1250 Special are equipped with a technology package that adjusts acceleration and deceleration forces to the available tire grip. The RDRS Safety Enhancements support the rider both when riding straight ahead and when cornering. Unnoticeable during normal riding, they prove particularly helpful in difficult road conditions and dangerous situations. They are electronically controlled and based on the latest chassis, brake, and drive control technology.

Some RDRS Safety Enhancements also work when leaning - a motorcycle-specific technology. Harley-Davidson motorcycles with RDRS Safety Enhancements have a sensor system (Inertial Measurement Unit, IMU) that measures the angle of inclination of the two-wheeler when cornering and transmits this information to the RDRS system. As the size of the front and rear wheels differs on many motorcycles, the two wheels rotate at slightly different speeds when cornering. The contact patch of the tire also changes as soon as the motorcycle into the bend. The cornering technology takes these factors into account and considers the lean angle when making its interventions.

• Reflex braking system with curve-optimized electronic brake force distribution (Cornering Enhanced Electronically Linked Braking, C-ELB)

The Reflex braking system with curve-optimized electronic brake force distribution ensures balanced deceleration at the front and rear wheels simultaneously during a variety of braking manoeuvres. The system couples the front and rear brakes more strongly the more braking force the rider applies. During light braking and at low speeds, the brakes work almost independently of each other. In combined mode, the system automatically applies braking force to the rear wheel when the handbrake lever is actuated. C-ELB takes the lean angle into account when controlling the braking force and modulates the braking force ratio with the aim of allowing the motorcycle to follow the line selected by the rider with the greatest possible directional stability. In the Off-Road Plus and Custom Off-Road Plus, the C-ELB is deactivated.

• Cornering Enhanced Antilock Braking System (C-ABS)

ABS prevents the wheels from locking during braking and helps the rider maintain control during emergency braking while riding straight ahead. It controls the front and rear brakes independently of each other. The cornering anti-lock braking system (C-ABS) also takes the lean angle into account in this control. When cornering, not all of the road grip is available for transmitting the braking force. C-ABS automatically takes this into account.

The cornering ABS also includes a wheel lift mitigation (RLM) function, which is based on the C-ABS sensors and a six-axis motion sensor system to counteract rear wheel lift during heavy braking, thereby optimally matching the deceleration forces to the driver's braking commands. The height and duration of rear wheel lift permitted by RLM depends on the selected riding mode. Intervention is strongest in Rain mode and weakest in Off-Road mode. In Off-Road Plus and Custom Off-Road Plus riding modes, both RLM and rear wheel ABS are deactivated..

• Cornering Enhanced Traction Control System (C-TCS)

Traction Control System (TCS) prevents excessive rear wheel slip during acceleration, thereby supporting the rider, especially in situations where tire grip is limited, such as in wet conditions, on suddenly changing road surfaces, or on unpaved roads. Cornering traction control (C-TCS) takes the current lean angle into account and thus also prevents excessive rear wheel slip when accelerating in corners. In each of the pre-programmed driving modes, the traction control and cornering traction control intervene to varying degrees. In the freely programmable driving modes, the driver can preselect the strength of the C-TCS interventions in three stages.

In addition, C-TCS can be deactivated in any driving mode when the vehicle is stationary and the engine is running. When switching to Rain mode, C-TCS is automatically reactivated, but can then be deactivated again. C-TCS can be switched off by pressing a button on the right-hand side of the handlebar.

TCS also includes wheelie control (Front-Wheel Lift Mitigation, FLM), which limits the height and duration of a front wheel lift during acceleration (wheelie). The strength of this intervention also varies between the different driving modes, with Rain being the most restrictive mode and Sport/Off-Road having the weakest intervention. When traction control is deactivated, the FLM function is also deactivated.

In Off-Road Plus and Custom Off-Road Plus modes, traction control operates without taking lean angle into account. This allows the rider to accelerate powerfully out of ruts, banked corners, and embankments. In Off-Road Plus mode, TCS allows even more slip at the rear wheel, which is only useful in pure off-road operation. At the same time, the FLM function is deactivated so that advanced riders can lift the front wheel over obstacles using the throttle.

• Cornering Enhanced Drag-Torque Slip Control System (, C-DSCS)

If the Cornering Drive Slip Control System (C-DSCS) detects excessive slip at the rear wheel during coasting, it adjusts the wheel's circumferential speed to the driving speed by regulating the engine torque. The system also takes the lean angle into account. Since the function is based on the ABS, it is naturally inactive in the Off-Road Plus and Custom Off-Road Plus riding modes. In addition, traction control may be impaired when traction control is deactivated.

• Hill Hold Control (HHC))

When activated, the Hill Hold Control (HHC) system holds the brakes for the rider to prevent the motorcycle from rolling away on a hill after the rider has released the brakes. This is mainly for stopping and waiting in traffic, such as uphill at a stop sign, downhill in slow-moving traffic, or on a steep parking garage ramp. In such traffic situations, HHC makes confident starting a breeze: the system automatically holds the motorcycle with the brakes until the rider accelerates and engages the clutch. HHC can also be activated on level ground if the rider wants to maintain their position without applying the brakes themselves.

The driver activates HHC after stopping with a short brake pulse using the handbrake lever or the foot brake pedal. If the driver continues to maintain brake pressure after heavy braking to a standstill, HHC is activated without an additional brake pulse. An HHC control LED informs the rider as soon as the system is active and the ABS automatically continues to apply brake pressure after the brake is released. If the rider attempts to activate HHC when it is not available—for example, when the side stand is extended—the indicator light flashes. To automatically deactivate the HHC function, the rider simply needs to start from a standstill or apply the brakes again.

HHC is not intended as a parking brake and therefore automatically releases the brakes when the side stand is extended or the engine is turned off. In most situations, the indicator light will start flashing after five minutes and HHC will automatically release the brakes shortly thereafter if no further input is received from the rider. HHC is not a substitute for a parking brake in any situation.

The driver can switch the HHC function off and on again via the display as desired.

• Tire Pressure Monitoring System (TPMS)

The TPMS tire pressure monitoring system displays tire pressures on the color display and warns the rider if tire pressure is too low. It comes standard on the Pan America 1250 Special and can be retrofitted to the Pan America 1250 at a specialist workshop on request.

driving modes

Various selectable riding modes electronically control the machine's riding dynamics and determine the intensity of the electronic interventions. Five modes are available for the base model, four of which are pre-programmed and one of which can be customized. In addition, the Pan America 1250 Special has two additional modes that can also be freely defined by the rider.

The pre-programmed riding modes for both models are Road, Sport, Rain, Off-Road, and Off-Road Plus. Each mode affects power delivery, engine braking, Cornering Enhanced Antilock Braking System (C-ABS), and Cornering Enhanced Traction Control System (C-TCS). On the Pan America Special, the modes also affect the function of the semi-active suspension.

The rider can select the riding mode using the Mode button on the right side of the handlebar, with a few exceptions, both when stationary and while riding. The selected mode is indicated by a separate symbol on the color display.

With the exception of Road mode, the driver can deactivate the driving modes in the Settings menu of the touchscreen display. The freely configurable modes can only be selected during operation using the Mode button once they have been activated in the Settings menu.

Overview of available driving modes

• Sport mode: Sport mode offers the most unfiltered interaction possible between rider and machine. The rider experiences the full performance potential of the motorcycle directly and with maximum precision, with unlimited peak power and full revving pleasure. The C-TCS operates at the lowest level that makes sense in road use and with an increased engine braking effect in coasting mode. On the Pan America 1250 Special, the damping is also increased in Sport mode more Feedback with a committed driving style.

• Road mode: The balanced Road mode is designed for everyday use and commuting. The engine delivers less peak power than in Sport mode, and C-ABS and C-TCS intervene earlier. On the Pan America 1250 Special, Road mode also activates a more comfortable suspension setting.

• Rain mode: This mode is designed for rain or other conditions that limit traction. This makes Rain mode ideal for riders who are still getting used to their motorcycle. Engine speed and power are significantly reduced in favor of controllable acceleration, as is the engine braking effect, while C-ABS and C-TCS operate at their highest levels. On the Pan America 1250 Special, the suspension is also tuned for maximum comfort in Rain mode.

• Off-road mode: This mode is intended for unpaved roads and moderate off-road use. Power output is limited to a medium level and the torque characteristics are optimized for off-road use with less torque and power in the upper rev range. In Off-Road mode, C-ABS operates on both wheels, but with characteristics specifically tailored to gravel and similar surfaces. C-TCS is active at the same level as in Sport mode. On the Pan America 1250 Special, Off-Road mode also sets the semi-active suspension to light off-road mode.

• Off-Road Plus mode: This mode supports experienced off-road riders in difficult terrain, ideally using off-road tires from the Harley-Davidson accessories range. The aim is to give the rider as much control as possible over the drive and brakes on slippery surfaces and obstacles, so that they can, for example, lock the rear wheel with the brake for controlled slides or lift the front wheel over obstacles with the throttle. The engine characteristics are the same as in Off-Road mode. Rear wheel ABS, combined braking, and DSCS traction control are deactivated, and traction control intervenes as little as possible. FLM and RLM functions are also deactivated, as is the lean-angle-dependent control of traction control and ABS, so that these systems always operate at a consistent level regardless of the current lean angle. On the Pan America 1250 Special, the semi-active suspension is programmed in Off-Road Plus mode to initially reduce damping during compression in order to more effectively absorb hard impacts, such as bumps, obstacles, or landing after jumps.

Note: Off-Road Plus mode can only be selected from Off-Road mode when the vehicle is stationary and the engine is running. To do this, the driver must press and hold the Mode button briefly. Off-Road Plus mode can be exited at any time by pressing the Mode button. This reactivates Off-Road mode, from which the driver can then select any other driving mode as usual using the Mode button.

• Custom mode: Freely programmable, this mode allows the rider to select a mode specifically tailored to their personal preferences or certain Events characteristics, such as for race training. Within certain limits, the rider can specify the engine characteristics, braking effect and torque as well as the intensity of the C-TCS and C-ABS interventions and, on the Pan America 1250 Special model with semi-active suspension, the damping. On the Pan America 1250 Special with optional automatic suspension lowering, the rider can set the time delay until the lowering kicks in or deactivate the function. A freely programmable custom mode is available for the Pan America 1250 and up to three different modes (Custom A, Custom B and Custom Off-Road) for the Pan America 1250 Special (see table above).

• Custom Off-Road and Custom Off-Road Plus modes*: Just like Off-Road Plus mode, the Pan America 1250 Special's Custom Off-Road Plus mode is designed for experienced riders and the most demanding terrain, ideally in combination with Harley-Davidson off-road tires with deep tread, which are available through the original accessories program. In this mode, the drive operates with the same power characteristics that the driver has selected for Custom Off-Road mode and combines them with the remaining settings of Off-Road Plus mode.

Note: Custom Off-Road Plus mode can only be selected from Custom Off-Road mode when the vehicle is stationary and the engine is running. To do this, the driver must press and hold the Mode button briefly. Custom Off-Road Plus mode can be exited at any time by pressing the Mode button. This reactivates Custom Off-Road mode, from which the driver can then select any other driving mode as usual using the Mode button.
