the older models 2007-2011 have from the factory what was called a 2nd,3rd gear restrictor. On those models a couple of wires could be cut that went to the gear box that disabled the restrictor , then those bikes would wheelie and go a bit harder(no restriction)Someone chime in on that one ya.
And if this doesn't let me power wheelie I'm selling the bike lol. Well prob not but c'mon right.
On the 2012 it seemed the bikes didnt have the gear restrictor and the ECU was new.
Its very very possible the 2016 and up uses the gear sensor to reduce loop time.
And maybe some evidence might be that an out of control wheelie lift may not give the appropriate protection with the wheel sensors considering the clutch can have a role. But a gear restrictor seemed to work very well on the early models.
theres probably 3 wires going to gearbox.
