The new G4 picks up where the famous G3 left off — three consecutive appearances in the Dirt 100 issue, as well as countless World Cup and FMB podiums made it the most sought after full-featured guide on the market. Upgrades to the G4 include a new co-molded upper guide that utilizes a softer durometer TPU material on the interior walls and ceiling to silence drivetrain chatter. An improved material formula is utilized in the updated skid — making the best even better.
