This switch has three modes mild, stock, and wild. On the mild setting the bike seems pretty slow and like it is not good for the bike to run it this way. I felt the same way about the Wild setting. I didn't trust the load it was putting on the engine. The main reason I didn't trust it was because when the switch is in the stock setting it does not ride the same as the actual "stock" electronics like if the switch were removed. The stock setting is not like stock. I was afraid it would hurt my bike. Instead I got "Wild" chip from KTM that you can install under the seat.
