ive dragged my stand to hell and back - even the pivot bracket that bolts onto the frame - ive dragged that as well, the center stand has never touched down for me, on the my first track day last weekend i never had a problem with either stand or center stand, i do however have a ohlins rear shock
which i dunno but has made the bike stiffer, more straight line accuracy and easier/quicker turn in, somehow i think the stiffer rear shock has less compression in turns and doesnt allow the swingarm to compress as much as it did with the OEM shock.
