The Triumph Rocket 3 R and Triumph Rocket 3 GT are two versions of the same model with some key differences. The Rocket 3 R is designed as a powerful roadster, highlighting raw performance and a sporty riding experience. On the other hand, the Rocket 3 GT is designed as a grand riding bike, prioritizing long-distance comfort and touring capabilities with features like a more relaxed riding position, adjustable footpegs, and a touring-oriented windscreen.
