I've 12500km on my 21011 speed triple, and my coolant reservoir, when it was new, was between the MIN and MAX mark. Now, it is at the MIN mark. Is it normal?? No white smoke by the exhaust, no white deposite on the oil dipstick.
But,somes time during hot days, when i'am stoping at traffic light, some coolant fall on the ground by the hose under the bike....
