Triumph so far has gone above and beyond with warranty , as long as your dealer doesn't give you a problem you should be OK. I have heard of starter idlers being fixed at no cost out of warranty and thats quite the job seeing as it requires new cases. I just got a new rotor and bolts for Wendys bike under warranty at no cost and her bike is 2 years out of warranty and I have done all the service work from the day we bought it.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
