This is my first official post on the board, although I have posted first in the "Welcome Forum".
I have been seeking an answer regarding the changes needed, if any, in throttle control during riding spiritedly with a pillion. As near I as I can tell, there does not seem to be much information out there regarding this technology. Given that the placement of weight on a motorcycle is critical to consistency and directly related to suspension set-up, it would be a logical conclusion to suspect that there are far more forces to compensate for given the added aft weight being applied to the rear of the bike. It is understood that there must be compensation in the preload of the rear shock to help the bike manage the added sprung weight, but how does this also impact the front suspension during heavy braking? These are all questions that I believe to be related.
So to elaborate, I am asking if throttle control must be altered in some way? It is established that the optimal weight distribution ratio in a turn is roughly 40/60. However, that ratio has been established on the principles of a solo rider and where his/her weight is likely placed. The amount of weight, say 140lbs, to the far aft section of the bike seems as though it would already alter the static balance of a bike. If this is the case, then it should, in theory, take far less throttle to achieve the 40/60 rule to achieve optimal traction. Since one must be on the gas enough to overcome the forces of cornering just to maintain a constant speed, and also give enough additional throttle to achieve 40/60, should there be much less roll on to achieve the 40/60 rule because there is a large amount of weight already added to the rear?
I have noticed that when standing the bike up out of a hard corner, that the front is already much lighter than when solo. I have had the front chatter excessively with a pillion aboard when it normally would not under solo conditions. This leads me to believe that the bikes limits were being pushed. The question is, was it my over aggression, suspension not set up properly or a force that cannot be compensated for as though it was just a much heavier rider sitting in the solo section?
If it CAN be compensated for through suspension, then that is another question. How? If it cannot be compensated for with hardware, then what must I change with the throttle to achieve maximum optimal traction? This question is based on clean dry pavement but it should apply over directly, as when solo, to hitting sand, gravel or the unexpected wet spot.
