That would have been for the service I hope but it's still expensive, I don't know what year his bike is, maybe it's out of warranty so had to pay for the work on the mount.
If it's in warranty still it's a bit much...

1600km service $415

Bike running 100% better. Added some Rush slip ons and power vision tune 2302 today big difference. Auto tune it over the wknd

this bike was disgraceful in stock trim majorly muffled and detuned to the max.
