Sunday Fun at Glen Helen Raceway: 2025 Triumph TF 450-RC Laps

Rare Sunday sessions at The Glen are the best! Good friends, great track, and proper practice days are tough to beat. At eleven hours, the Triumph is the best it's been through break-in: Light in action, predictable, and confidence inspiring, the addition of a Dunlop MX3S front tire and a few small clicker changes had me feeling the flow. #Dialed
