ok , you're both wrong , t100c is a trophy , t100r is the daytona and t100s was the tiger .
there was also a t100t daytona tiger .
a little rough for a bike that supposedly was only ridden for 3 years then garaged . worth $600 sure up to maybe $1200 or so if the motors ok .
how mechanically inclined are you ? it's going to take a bit of work to make it worth a bunch more .
btw those are the wrong pipes for a t100c .
theres a picture of what that bike should look like here plus an explanation on the various t100's .
