Power Output and Torque Delivery Characteristics
The engine produces 127 horsepower at 4,900 revolutions per minute and 145 foot-pounds of torque at 4,000 revolutions per minute. These figures indicate a strong midrange torque curve, allowing consistent acceleration without requiring high engine speeds. Torque delivery at a relatively low rpm improves throttle response during acceleration and passing maneuvers. The engine torque measurement follows the J1349 standard, ensuring consistency in reported performance values.
The drivetrain includes a six-speed Cruise Drive® transmission. Gear ratios range from 10.233 in first gear to 3.067 in sixth gear, providing a broad spread between low-speed control and highway cruising efficiency. The clutch is a mechanically actuated 10-plate wet design with Assist and Slip functionality, which reduces lever effort and manages rear wheel behavior during downshifts. The primary drive uses a chain with a 34 to 46 ratio, while the final drive uses a belt with a 30 to 68 ratio. This combination supports durability and smooth power transfer.
Structural Frame and Chassis Composition
The frame is constructed from mild steel using a tubular structure with a two-piece stamped and welded backbone. Cast and forged junctions are integrated into the frame to improve strength at critical connection points. The chassis includes twin down tubes and a bolt-on rear frame section with forged fender supports. The swingarm is also constructed from mild steel with a two-piece drawn and welded design and forged junctions. These construction methods support rigidity and load distribution during operation.
The 2026 Harley-Davidson® CVO™ Road Glide® ST has a running order weight of 838 pounds and a gross vehicle weight rating of 1,360 pounds. Front axle weight rating is 500 pounds, while the rear axle rating is 927 pounds. These figures define load capacity and distribution limits. Ground clearance is measured at 5.1 inches, which supports lean angle capability while maintaining underbody clearance.
Suspension System with Multi-Axis Adjustability
The front suspension consists of 47 mm inverted 1x1 forks with adjustable preload, compression damping, and rebound damping. This configuration allows riders to adjust the suspension based on load conditions and road surface variations. Rear suspension uses an emulsion shock system with adjustable preload, compression damping, and rebound damping. This provides a consistent damping response and allows for tuning across different riding scenarios.
Front suspension travel is 4.6 inches, and rear suspension travel is 3 inches. These values support a balance between ride compliance and chassis control. The suspension system is designed to maintain tire contact and stability during braking, acceleration, and cornering inputs. The adjustability enables fine-tuning without requiring component replacement.
