This is the maintenance schedule for the Indian Chief range of motorcycles sold between 2014-2020 with the Thunder Stroke 111 engine, replacing the earlier pre-Polaris Chief which had the PowerPlus 105 c.i. engine.
The Indian Chief is one of the new Polaris-owned Indian’s big cruisers. It’s based on the same platform as a few other motorcycles of the era, using the big Thunder Stroke 111 engine, an impressively modern, reliable, and capable air/oil-cooled V-twin — the format of engine that the original Indian invented over a hundred years ago.
The Indian Chief line between 2014-2020 included a few variants on the same motorcycle:
- The base model Indian Chief, a stripped-back cruiser
- The Indian Chief Vintage
- Indian Chief Classic
- The Indian Chief Dark Horse
All these Indian Chief models had a lot in common, fundamentally the same chassis and the same 1811 cc (111 cu.in.) air-cooled V-twin engine. They make peak torque of 119 ft-lb (139 Nm) at a low 3000 rpm, putting it down via a six-speed transmission and belt final drive.
Indian took a hiatus on the Chief in 2021 (though still made the similar Chieftain), but revitalised the Indian Chief completely with the 2022+ Indian Chief, blessing the new model with the Thunder Stroke 116.

Indian Chief (2014-2020) Service Intervals
At its base, like many air/oil-cooled Indian motorcycles, the Indian Chief motorcycles have 5000 mile / 8000 km service intervals, at which point you change the oil and filter and do a bunch of other checks for leaks, correct lubrication, and wear.
As the Thunder Stroke engine has self-adjusting hydraulic valve lash adjusters, there is no valve service interval for the Indian Chief.
However, there are a few unusual bits about maintaining Indian bikes. For one thing, they recommend changing the fork oil periodically — every 15000 miles (24000 km) or two years, whichever comes first. The same interval applies for changing the spark plugs and air filter.
As it has a belt drive, you should also regularly maintain the belt, checking its condition and tension. Adjust tension and replace it as necessary.
Aside from that, keep your brake fluid up to spec and make sure your brake pads don’t wear out. There’s little else to do on your Indian Chief.
Maintenance schedule for the Indian Chief
Below is the maintenance schedule for the Indian Chief.
For clarity it’s broken up into two parts:
- The standard inspection checklist — to be done at every service interval
- The scheduled service list, including a few long-term service items

Drive belt maintenance
You should periodically look at the drive belt’s condition. Make sure that it’s clean and not excessively worn.
Below you can see some examples of wear that mean it’s time to replace the drive belt, and maybe the other final drive components.
Indian also says you should check and adjust the drive belt tension. For the Indian Chief (including the Chief Dark Horse and Vintage), the appropriate drive belt deflection with 10 lbs of force is 1.1 inches or 28 mm.
To adjust the belt tension on the Indian Chief, get the motorcycle in an upright position. Loosen the axle nut, and tighten it slightly to “adjustment spec” (20 Nm / 15 ft-lbs).
Use the right side adjuster to get to the right belt tension. You might have to tap the axle to get both sides of it to move.
Use the left side adjuster to get final adjustments to belt alignment. Then tighten up the axle nut again to 65 ft-lbs / 88 Nm.
Wheels and tire pressure specs for the Indian Chief

About the Indian Chief (2014-2020)
The Chief has been a mainstay of Indian motorcycles for as long as the brand has existed in its many forms.
When Polaris bought the Indian brand in 2011, Indian already had an Indian Chief in their lineup. But it was powered by an older motor, the 105 c.i. PowerPlus.
The Polaris-owned Indian replaced the PowerPlus 105 with the Thunder Stroke 111, also written Thunderstroke (even Indian changes the way its written, but usually has a space). It’s a completely different motor, one that the new Indian implemented for more torque, more reliability, and even better feel.
The Thunder Stroke 111 engine is very well-loved, even though it hasn’t been around for long. It has quite an old-fashioned design. Just two valves per cylinder, pushrod-actuated valves, and air-cooling (with an oil cooler fitted too). This is a far cry from many more advanced bikes these days that have multiple valves, variable valve timing, and of course advanced cooling to keep everything in spec for even longer.
But what the TS 111 does is produced a lot of low-down torque and a very familiar vibey feel that cruiser owners have come to appreciate. Harley-Davidson has done it best for a long time. Other manufacturers have struggled to replicate it, but Indian has come the closest so far — to the point where a lot of cruiser diehards have been won over.
The rest of the 2014-2020 Indian Chief is almost as you’d expect. It’s a big, heavy, comfortable motorcycle, with nothing astoundingly high-spec. But some parts are surprising.
For brakes, there isn’t just one, but two front rotors with four-piston calipers on them. And while the front fork is a non-adjustable unit as you’d expect, at the rear there’s a monoshock rather than twin shocks like you might expect on a cruiser.
Finally, the Chief has come standard with ABS since Polaris launched it.
Indian didn’t make any changes to the drivetrain of the Indian Chief motorcycles during their tenure, but there were some changes to style and even technology.
In 2017, Indian motorcycles started getting the Ride Command system as an option — an LED screen with GPS and access to your phone, as well as control of your sound gear (if you have any fitted).
In 2018, Indian had to improve the performance of the Thunder Stroke 111 engine to keep it interesting while keeping it EU4 compliant. Indian managed to improve the exhaust tone at the same time. The 2014-2017 Thunder Stroke 111 engine made a peak of 103 ft-lb (139 Nm) at 2600 rpm, whereas the 2017-onward Thunder Stroke 111 makes 119 ft-lb (162 Nm) at 3000 rpm. It’s a slight bump in torque, compensating for the fact that it doesn’t come on quite so early.
The Indian Chief has come in a range of variants, including the Vintage, the Classic, and the Dark Horse. They all have the same fundamental drivetrain and the same maintenance schedule.
Indian made a huge number of structural and spec changes to the Indian Chief for the 2022 version, starting with the chassis, as well as giving the new 2022+ Indian Chief the Thunderstroke 116 engine (the only option in many markets).
