The long and short is it is a mechanical device. At any point it can and some point will- fail.
All bike have issues- my Honda's (both) ended up with flat cams, Yamaha had starter issue, Concourse (Kawai) leaked oil from the input shaft of the shifter- every 10k miles need a reseal.
these appear to be grat bikes. Triumph ranks at the top in overall lowest operational costs. Mine is a yerar old. so far only the speedo cable has been as issue.
