just a quick question have just bought a 2003 cbr600rr seems to run great but the digital temp gauge is reading up to 108c while sitting in traffic is this normal and will it go evan higher in summer

 

is the fan turning on? and sport bikes don't like sitting still so they will run hot until you get moving. your good as long as the fan kicks in.I would recommend changing your coolant and oil. I use water wetter instead of coolant and my bike's fan rarely turns on unless its a hot day.
