+1 for it being personal preference, but I cannot figure out why anyone would have standard as their personal preference! lol
Not many cons, other than getting mixed up.
1.) It makes so much sense when you're riding!
2.) You never downshift when you're leaned over, but you do upshift while leaned over. Now you don't have to try to move your foot and get it UNDER the lever in order to shift.
3.) on high speed straights you can stay in a full tuck and use the least amount of effort to upshift.
4.) Downshifts occur when you're sitting up typically anyway, so it's easy to get your foot under the lever to downshift.
I'm sure there are more, but I'm still sleepy :)
Gonna play devil's advocate here for an explanation why GP shift is not standard and standard shift is, well, standard. Most are taught and it's enshrined in MSF instruction to do all your shifting and braking before turning. Also taught in emergency stopping to do the same things with both hands and feet. Pull in on both hand levers and tapping down on both foot levers. For general purpose motorcycle riding this is all very logical. There are more occasions for fast downshifting than upshifting. It's only racers or performance oriented riders who would want to upshift while mid corner. In other riding you would enter a corner in a gear appropriate to see you all the way through and there's plenty of time to upshift when you're back mostly upright. It would make sense though for regular track riders and racers to run GP shift on the street as it facilitates one mode of muscle memory.
Two awesome replies from a track and dirt perspective.
