"seconds" as in not the first or best or not quite to specification but willing to use them anyway to save on Mfg. costs.
Having personally had two brand new bikes of the same type within 7 mos of each other have the same issue while other models have not, causes me to draw that conclusion.
Having said that I realize that when in manufacturing, at times due to varying factors, bad runs of parts may occur and it is not feesible to check every part. It is assumed that as long as the part is within certain tolerances that there will be no major concerns as the part should function normaly within a normal expected lifespan.
I just happened to have two bikes with the same problem. I see from this forum that apparently many others have had the same or similar problem. But apparently the rotor problem was not widespread enough to warrant a recall by Triumph.
