The next major change came with the 1973 and 1974 T150V, with addition of a much-needed hydraulic front disk brake and the long-awaited 5-speed gearbox, which is what the "V" stands for in the model designation. Styling was cleaned up also, in keeping with the Bonneville line.

The worker strike the closed the Meriden plant and crippled the company occurred early in 1974, cutting '74 Bonneville and TR7 to a trickle. But Tridents were built in BSA's Small Heath factory alongside their Rocket 3, so production went on unabated. Of course, by this time, Triumph had ceased to exist as a company, along with parent company BSA, replaced by the worker-owned Meriden Co-op who were strapped for cash from the very start. They often didn't have enough money to pay for the parts needed to finish a shipment of bikes, bikes didn't get shipped, orders didn't get filled, the money from those sales didn't come in, and the Co-op's situation worsened by the day.

So, even though they were free to build Tridents at Small Heath, unfettered by the worker lockdown, they had neither the money to build them nor the customers to sell them to.
