From Harley website:

Some bikes make history. Others rewrite it. In 1988 and 1989, Willie G. Davidson rode early Fat Boy® prototypes into Daytona, seeking direct feedback from riders and igniting a legacy that would span generations. By 1990, the Fat Boy was born, quickly becoming one of the most legendary models in Harley-Davidson history. Now, 35 years later, the new 2025 Fat Boy® Gray Ghost charges forward, bringing that legacy full circle. Inspired by the riders who made it an icon, this tribute honours the past while the next generation keeps the fire burning.

The original Fat Boy® set the standard, and the all-new 2025 Fat Boy® Gray Ghost takes it further. Its legendary silver and yellow color scheme returns, now with a stunning mirror-like finish created through an advanced Physical Vapor Deposition (PVD) process, plus full LED lighting for a bold, modern edge.
The Fat Boy® Gray Ghost blends classic style with modern power. The Milwaukee-Eight® 117 Custom V-Twin Engine and timeless round air cleaner give it the perfect mix of muscle and attitude.

All the benefits of Rider Safety Enhancements and Ride Modes are hidden in classic cruiser form and managed with intuitive, ergonomic hand controls.

Harley-Davidson’s Rider Safety Enhancements is all about giving you that extra peace of mind when things get a little unpredictable. It’s a set of smart tech that steps in during tricky situations, helping the bike handle traction while you’re accelerating, braking, or slowing down. With the Cornering Rider Safety Enhancements, the bike even adjusts for cornering, keeping things smooth and steady without you having to think twice.

ABS is designed to prevent the wheels from locking under braking and helps the rider maintain control when braking in a straight-line, urgent situation.

Drag-Torque Slip Control System (DSCS). DSCS is designed to reduce excessive rear-wheel slip and help prevent rear-wheel lock under powertrain-induced deceleration, which typically occurs when the rider makes an abrupt downshift gear change or quickly reduces the throttle while on wet or slippery road surfaces.

Traction Control System (TCS).The TCS is designed to keep the rear wheel from “spinning out” when the motorcycle is accelerating in a straight line and enhances rider confidence.
Tire Pressure Monitoring System (TPMS). TPMS alerts the rider through the information display to low or high tire air pressure. Maintaining proper tire air pressure is important both for vehicle performance and tire life.

Cornering Enhanced Anti-lock Brake System (C-ABS). C-ABS is a variant of ABS that takes into consideration the lean angle of a two-wheel motorcycle, or the lateral acceleration of a Trike model. The brake pressure required to limit wheel slip when cornering is typically or lower than the pressure required under straight line operation.

Cornering Enhanced Traction Control System (C-TCS). C-TCS is designed to prevent the rear wheel from excessive spinning under acceleration when going straight or cornering.

Cornering Drag-Torque Slip Control System (C-DSCS). On bikes equipped with C-DSCS, the system helps keep the rear wheel from slipping or locking up when you quickly downshift or let off the throttle, especially on wet or slippery roads. When turning, it can adjust based on how much a two-wheel bike is leaning or the side-to-side motion on a Trike.
