Among the consumable items associated with a motorcycle, the tires probably have the most profound effect on performance and rider feel. This point was recently driven home, just two weeks after spooning on a new set on my sportbike. Murphy took up residence, puncturing and slashing the rear tire into submission. I repaired the puncture with an internal patch, but the cut was too much. Barely 800 miles had passed and I was now faced with shelling out yet more $$$ for a replacement. Grrrrr….
