All are available via Triumph Motorcycle Finance, provided by industry experts Black Horse Limited, and you can finance all or part of your next new or used Triumph, including any accessories that you've added.

Triumph TriStar Finance Plans | Lings Triumph

Riders love control. So if you like to control your motorcycling expenditure and would also like a brand new Triumph every two or three years, you should be considering a TriStar PCP (Personal Contract Purchase) for your next bike. This is how it works:

Decide on your Triumph and pay a deposit, agree affordable monthly payments based on your proposed annual mileage and ride away.

You will be given a guaranteed future value for the bike at the time of purchase, so at the end of the agreement, you have three options, either:

  • part exchange it for a new Triumph,
  • pay the final payment and own the bike,
  • or, return the bike*

You have the option of taking the finance over two or three years to suit your budget.

And your Triumph dealer arranges the finance documentation. You just check the paperwork, sign on the dotted line and ride away.
