What tire pressure does everyone have in there tires ? I was told to run 40

 

Are you running the stock OEM tires? The correct pressure in listed on the Owners Manual. Sorry, I don't have a 48 OM.
Tire air pressures vary based on the tire manufacture, not the bike manufacturer, so if you've replaced the stock tires with something else, you need to refer to the tire manufacturer (website) for correct inflation pressures.
