The Beta RR 50’s chassis is built for durability and agility, featuring a steel double cradle frame that enhances stability while keeping the bike lightweight at just 85 kg (187.4 pounds). The front suspension boasts a hydraulic fork with a 41 mm shaft, providing excellent shock absorption and handling on rough surfaces. Meanwhile, the rear monoshock with adjustable spring preload caters to rider preferences, ensuring a customized experience. With front and rear disc brakes—260 mm and 220 mm respectively—stopping power is reliable, allowing for confident descents and tight cornering. The bike's compact dimensions, including a seat height of 930 mm and a ground clearance of 360 mm, make it accessible for various rider heights and skill levels. ####
