We know. Like several of the following items, this one seems too obvious. And for riders who keep a close eye on such things, it is. But proper tire inflation--along with routine tread-wear check--is key to a fine-handling motorcycle. It's also cheap insurance that can keep you from stepping off your bike in an unplanned way. Always be sure your bike's tires are inflated to the correct pressure(s). That doesn't mean the max pressure number listed on the tire's sidewall; that number is reserved for heavy-duty riding (two-up, loaded with luggage, etc.). We've always found the mid-30s (34-38 psi) to be a good overall pressure range. Slightly lower pressures (low 30s) typically result in more grip (and more wear), while higher pressures equal less wear and firmer ride qualities. Also, check the tread for wear, especially the uneven sort. Cupping around the edges or a flat-spotted tread crown can adversely affect handling. If you find these conditions, replace the tire.
