The Beta EVO 80 Sr is the larger-scale youth trials machine designed for riders ages 11 to 15 who have outgrown the Junior model but aren't quite ready for a full-size 125. It utilizes the same reliable 79.6cc liquid-cooled 2-stroke engine and 6-speed transmission as the Junior, but upgrades to a full-size wheel configuration with a 21-inch front and 18-inch rear. This change increases the seat height to 26 inches and provides significantly more ground clearance for tackling larger rocks and logs. Weighing 145 pounds, the Senior model features enhanced 38mm hydraulic forks and a chassis geometry that mimics Beta's adult competition bikes, making it the definitive stepping stone for young competitors serious about advancing their trials skills.
