Indian Motorcycle: The Thunder Stroke 111
Take a look inside the Thunder Stroke 111™ engine. A forged single pin crankshaft, extensively tested for over 1 billion revolutions, is the heart of the 49 degree V-Twin. A three cam pushrod engine allows for a reduction in overall height, centralized mass, and maximum torque.
The six speed transmission features helical cut gears for smoothness, reliability, and easy shifting. The large clutch is designed to harness that power without a heavy clutch pull. One thing is for certain, The Thunder Stroke 111™ will never be mistaken for average.
Choice is Coming to American Motorcycles.

What a beautiful Motor!
Quick question about the engine. why does it need 3 cams for a total of 4 valves to operate? 1 for each cylinder. sure. but what does the 3rd do?
cool bikes tho! saw it on Jay leno's garage
. why not a performance bike? these are just heavy bikes for 50+ year old ppl.
really? Pushrods? Comeon! POS
1800cc ?
dreams are not that far away …….
So thats how they're assembled.
Looks good
Murica!!!
What a great motor. Had a chance to ride on of the new Indians and loved it.
It's a masterpiece of industrial design. I want one for my living room.
This is an extra-ordinary engine…very impressive torque…outstanding get up and go…supe smooth. Good job Polaris and Team for bringing the V-Twin motor to modern specs.— Motorcycle Marc. #Thunderstroke111
The one weak link, in this otherwise, well designed, engine, in my opinion, seems to be the use of a silent chain drive for operating the cams.
This engine should have used a gear drive, to drive the cams, instead, like the Harley Twin Cam engine, they use a PLASTIC chain tensioner to rub against a METAL chain, which means periodic inspection and replacement of the PLASTIC tensioner.
Imagine cruising at 3,000 rpm and the tensioner breaks up, could get sucked into the oil pump and then the crank case and cylinders and catastrophic engine failure can occur, like on the Harley Twin cam, which uses TWO, silent chain drives, and TWO PLASTIC tensioners, instead of one for the Indian 111 Thunder stroke.
Would be interested to see if Indian publishes an inspection interval, and replacement interval in their owner's manual or in their Service manual, as Harley does not, and most owners, don't even know about the tensioners, till their engine craters.
THERE ARE LOTS OF YOU TUBE VIDEOS ON THE HARLEY CAM TENSIONER PROBLEMS AND THEIR PRESSED TOGETHER, FLYWHEEL ASSEMBLIES WHICH WILL COME OUT OF TRUE, SOONER, RATHER, THAN LATER AND CAUSE CATOSTROPHIC ENGINE, FAILURE, THERE, AS WELL.
I really applaud Indian for making this video for all the Gearheads out there (like me). It's really cool to see all the internals come together and how they operate, while they highlight the different technologies they applied. For all you haters, this is what you might call, "RetroMod". It's not built for a Japanese race bike. It's a tribute to what people love and want from an American Cruiser, with newer and more reliable technology built in. They built it that way on purpose.
Great video. I friggin' LOVE my Chief Classic. It's a torque monster at any speed…and a damn tank. Solid.
muito maneiro
so kool
What a great video! The last 30 seconds takes the cake! Will buy.
I am drooling. This engine sounds so beefy. Can't wait to ride one.
Wow! Extremely complicated.
1:29 BLISS!
Harley Davidson released their new engine design recently. Here comes Indian trailing from behind. 🙂 Cool video tho.
HERMOSO
