Plastic gas tank has expanded. Likely due to ethanol in fuel causing water absorption in plastic. Tank is very difficult to install after removal. Stress on tank because of improper fit could cause cracks and leaks.

What 2001 Triumph Sprint ST owners say
Most recent owner complaints, unedited.
Fuel tank was removed from motorcycle to install a new throttle cable. When fuel tank was reinstalled, the mounting holes for the fuel tank no longer lined up, the fuel tank didn't fit between the frame rails and to mount the fuel tank a considerable amount of pressure needed to be applied to force the mounting holes to line up. This puts the whole tank under severe stress and could cause leaks. The next time it is removed, I do not believe the tank will go back into the motorcycle. This seems to be a common problem with any of the plastic tanks due to ethanol fuel that is required here in the us on many makes/models of the motorcycles.
Starter cross shaft outboard support bearings in transmission and crankcase. Intake/exhaust valves beyond minimum lash, caused by faulty engine ecu. Faulty ecu, can not be "read" or accessed by factory diagnostic tool , creating excessive exhaust heat burning holes in bodywork, possible fires and burning legs of rider. Dealer will only agree to customer payment of complete overhaul and replacement of faulty ecu which has had this problem since new. Estimates exceed vehicle value. Certified letters, phone calls and emails to north american distributor go unanswered.
Fuel quick-disconnect failure. On a triumph sprint st. This part failed and was required to be replaced.
Plastic, quick-connect fuel fitting at the gas tank cracked and was leaking large amounts of fuel down the back side of the engine, along wiring, and straight on to the exhaust.
Defective fuel fitting on 2001 955 sprint s/t started leaking.*mr dealer was notified.
