3. Optimal front–rear braking
In racing motorcycles the role and the importance of rear
braking is very debated as, in practice, during a hard
braking on a straight line, most of the drivers make no use
at all of the rear brake. This brake is typically used for
better managing the attitude and the stability of the
motorbike during a bend. The reason is threefold:
  •  Due to the (almost) total load transfer to the front tire at
    mid-low speed in a hard-braking maneuver, the braking
    capability of the rear tire is comparatively small.
    
  • The simultaneous optimal management of the front and
    rear brake is a very hard task even for a professional
    driver.
    
  • If the engine is engaged during braking, the load torque
    of the engine (especially on high-performance highcompression 4-stroke engines) in many cases is high
    enough to lock the rear wheel; this phenomenon can be
    alleviated using mechanical devices called ‘‘anti-hopping’’ clutches, which can be considered as a raw antilock braking system acting on the engine-induced
    braking torque.

Pro-racers have problems accurately modulating both brakes but n00bs in a 2 day program can learn it easily right?

So which is it MSF the program is so basic and the riders skills are so low that you don't have time to teach things like trail braking.

Or the program is so good that it can teach "advanced skills" like accurate rear brake usage?

Or your program is so cruiser oriented that it's under serving the sport bike community.


The study shows that both brakes provide .3 seconds better braking performance from 300km/h which is about 23ft. That's entirely because at high speeds aerodynamic forces. The cross over point occurs at 200km/h above 200km/h the aerodynamic forces keep the rear down and front tire traction is the limiting factor, below that speed rear wheel lift is the limiting issue.
