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, and the Thunderbird range fits into this last category.
The Thunderbird 1699 cc range made its appearance first in 2009 and it has been really popular ever since. They’re well-built, good-looking, and very reliable. (Purely 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. All of the Thunderbird motorcycles share the same basic platform of a 1699cc parallel twin with a 270-degree crankshaft. The engine is a DOHC 4-valve-per-cylinder motor that’s liquid-cooled, and it puts power down through a belt (much like many other big cruisers).
The engine puts down 73 kW (98 hp) @ 5,200 rpm, but what’s more impressive is the torque figure — 156 Nm (115 ft-lb), peaking at a low, low 2950 rpm. A lot of torque is available earlier than that, too. So the Triumph Thunderbird definitely has the ability to spin the wheels and make a lot of noise, just like the big V-twin cruisers from which it’s trying to take attention.
Like other cruisers, the Thunderbird has a very low 700mm (27.6 in) seat height, which makes it very easy to ride for a broad spectrum of uers.
