I have a 2008 R1200 GSA with the tire pressure monitoring system. Although the tires are correctly inflated when I first start out on a ride everything is fine. Approximately 10-15 minutes into riding the tire pressure system alerts that both from and rear tires have no tire pressure. The yellow warning light illuminates and on the gauge the pressures read as dashes. After another 20 minutes and sometimes a stop or two it resets itself and everything is fine.
Any ideas why this is happening?
Thanks for your help.
