Triumph Thunderbird (1699cc, including Storm, LT, and Commander) Maintenance Schedule

This is the maintenance schedule with associated service intervals for the Triumph Thunderbird motorcycles with a 1699cc engine.

Triumph has been making Thunderbird motorcycles for ages. But they made their first 1699cc Thunderbird with the Triumph Thunderbird Storm in 2011.

The Triumph Thunderbird LT and Commander were produced between 2014-2018. They’re mechanically identical to each other (and to the Storm) except for external features.

  • The Storm is blacked out and tough looking
  • The Commander has more chrome and has a narrower front tyre, and a different rake angle.
  • The LT has a windscreen, floorboards, and bags.

Otherwise, mechanically, they’re the same. The Triumph Thunderbirds of this period share a 1,699cc (1,700cc, let’s say) liquid-cooled parallel twin, with dual overhead cams, 4 valves per cylinder, and drive the wheel through a 6-speed transmission and a belt drive.

Between the three, the Triumph Thunderbird LT was the more popular motorcycle. Reviewers said the Commander had poorer handling, and owners said the Commander was less comfortable. In the world of big cruisers, comfort is everything!

Oh yeah there was also the Triumph Thunderbird Nightstorm. Even more black!

General information about the Triumph Thunderbird LT and Commander

Triumph has always made a huge range of motorcycles. They make racy sportbikes, upright standards, and massive cruisers.

The Thunderbird made its appearance first in 2009 and it has been really popular ever since. They’re well-built, good-looking, and very reliable. From a maintenance perspective, I personally love having a parallel twin rather than a V — it’s just easier to get at the one cylinder head, and there are fewer gaskets to fail.

Triumph’s Thunderbird evolved into the Storm, and now to the LT and Commander. Both motorcycles push out 101 lb-ft of torque at 3,300 rpm, and some amount of horsepower that won’t matter to cruiser riders and won’t impress sport bike riders, so why mention it!
