FAQ: Why does the engine sound different with the brakes on?
This falls into the category of "they all do that".

While idling, the engine noise (and associated vibration) changes when the rear brake is applied because the rear wheel is being clamped to the engine via the brake calipers. This allows vibration to travel through the frame via different paths, and also provides additional dampening that otherwise doesn't occur very efficiently through the axle alone.

The change in engine noise and vibration is not because of additional load being put on the engine. Stopped is stopped, and the centrifugal clutch is disengaged regardless.
