Testing out Yamaha's "LIF Control" system which is essentially wheelie control. Whilst I don't personally use the system, this test demonstrates that it is actually a really good system and that it is also rather sophisticated when compared to other "wheelie control" systems available today. Unlike some crude systems found on other motorcycles, power is not cut, but rather it is metered to maintain control and forward momentum.
The system uses the inertial measurement unit (IMU) to detect the angle of attack of the motorcycle (i.e. a wheelie) and the rate of climb of the front wheel, it then introduces intervention (closing the throttle butterflys, retarding ignition timing) to control the rate at which the front wheel climbs, and also the maximum allowable angle of attack. Note the system will not allow the bike to reach "balance point", nor will the system permit "clutch up" wheelies. The intervention is adjustable through levels 1-3 and OFF (our favorite). Level 1 representing the least amount of intervention in the ON setting.
The intervention also appears to be mapped for each gear, introducing more intervention (lower angle of attack, slower rate of climb) as speeds rise (probably for safety reasons).
it would be interesting to compare 0-60 & 0-100 times with the system on and off... Maybe a future video.
