Technical Overview

2024 GAS GAS RX 450F Replica Technical Analysis & Specification Breakdown

Engineered by GAS GAS for the enduro - offroad motorcycle segment, the 2024 GAS GAS RX 450F Replica relies on a 449.3 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 95.0 x 63.4 mm (3.7 x 2.5 inches).

On the scales, the RX 450F Replica measures 100 kg (220 lbs) dry. Rider ergonomics and chassis geometry center around a 950 mm (37.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 35-liter (9.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
