Tie strap - tank
A tie strap that helps secure the petrol tank on OIF-era Triumph twins with the 2.8 or 4 gallon tank.
This is the tie strap that helps hold the petrol tank steady on OIF-era Triumph twins, appearing across the gas tank and twinseat figures for both the 2.8 gallon and 4 gallon tank variants in the parts books. It works alongside the tank's mounting brackets to keep the tank from flexing or shifting under vibration, which was a known headache once tanks went to the slimmer, split-halve construction used on these frames.

The part shows up in catalog listings spanning the mid-1970s into the mid-1980s, so it's a long-lived item across that OIF tank lineup rather than tied to one single year. If you're replacing a cracked or worn strap, it's worth checking the tank mounting bracket and rubber isolators at the same time since they all work together to keep the tank secure.
Call the shop if you're not sure which tank size or mounting setup your bike has - matching the strap to the correct tank figure in the parts book will save you a return trip.
