All our 450s sounded loud for the first 1000-2000Km These scooters must be brand new. Maybe that’s why the sound?
But it’s already run many kms in test rides itself. Noise is irritating to drive.
Means it’s 450 scooter with wrap mode ?
Correct called for warp mode trial.
When I picked that scooter up, ODO was 178kms only. But compared to 450 it’s noise is high.
