In a way good news. I guess it is the only viable solution. So frustrating when having hiked for a couple hours and think you are away from everything and then hear a few noisy motorbikes at several kms distance.
I feel sorry for those who do just slowly cruise around on their larger motorbikes without noisy exhausts, just enjoying nature and respecting the wildlife.
After all, there are also cars with very noisy exhausts, road raging through the parks and causing equal disturbance to the wildlife and other visitors.
As well as small motorbikes that produce quite a lot of noise too.
But to equip every national park entrance with decibel meters and roller banks to test each vehicle prior entry is not a real option either I am afraid.
I guess in this case the percentage of 'trouble makers' amongst this group of vehicles has been too large.
