The Guerrilla 450 is Royal Enfield's modern roadster, launched in 2024 on the same liquid-cooled 452 cc Sherpa engine as the Himalayan 450 but in a lighter, shorter-travel chassis. It rides on 17-inch wire wheels with wide road tyres and a steel twin-spar frame. It was sold in Analogue, Dash and Flash trims and is badged GRR 450 in much of Latin America.
