Overview
The Triumph Rocket 3 GT is a cruiser produced from 2020 to 2024. The 2024 model has a naturally aspirated, liquid-cooled 2,458 cm³ inline three-cylinder engine producing 180 hp (134 kW) and 225 Nm at 4,000 rpm; its wet weight is 320 kg.
A 750 mm seat height gives the bike a low seating position, while its 320 kg wet weight can make low-speed maneuvering demanding. The 18 L tank provides a calculated range of about 265 km, and the shaft final drive avoids chain cleaning and adjustment. Showa suspension is adjustable at both ends, including remote hydraulic rear preload adjustment.

Pros and cons
Advantages
Strong low-rpm torque
The engine delivers 225 Nm at 4,000 rpm, giving it substantial pulling force without needing high engine speed.
Shaft final drive
The shaft drive eliminates routine chain cleaning and adjustment.
Adjustable suspension
Compression and rebound adjustments at the front and remote hydraulic preload adjustment at the rear let riders tailor the suspension.
Things to consider
Heavy at low speeds
At 320 kg wet, the Rocket 3 GT can take effort to maneuver when moving slowly or backing up.
Limited distance between fuel stops
Its 18 L tank and calculated range of about 265 km mean fuel stops come around sooner on longer rides.
