Friend of mine bought a new Thunderbird LT, broke it in, then rode to RAA at the Hub. Engine light came on on the way back to Michigan. The dealer couldn't seem to diagnose it right away. After a few test rides something let loose in the motor. Triumph authorized a tear down. They felt it was in the lower end of the motor. He wasn't comfortable with a rebuild on a bike with 3000 miles, so after more weeks of triumph not responding to calls and emails the dealer said that triumph was sending a new motor. Next thing few weeks later the motor supposedly was lost in India. By this time he has had it with triumph corporate. We left RAA X beginning of May, triumph finally did reimburse him in full plus the add ons and tax, but not until late September early October. No bike and poor communication for 5 months and really never offered up a new bike. The dealer was then told to rebuild it and put it on the floor. He was also told no lemon law on motorcycles. Seems really uncommon for that motor, I would go buy another one, but he's not. I always wondered what that 1700cc motor ended up on in India.
