Triumph Sprint ST 1050.
I loved the bike when it ran right. Sadly it did not do so all that often.
Coolant hoses poped off and bulged. Rear axle bearings dried up and failed. Bike was an unbearable furnace in 90F+ weather even in full leathers. Getting it started in the cold was a chore. The fuel gauge would stop working in the cold as well. Right heated grip stopped working. Sometimes the engine would stall when cutting the throttle. All this in less than 16k miles.
I loved riding the bike. I hated the clueless dealers, expensive parts with long wait time (5 weeks for wheel bearings).
