Breaking News. Indian Motorcycle Just Unveiled The Thunder Stroke 111 To Power The 2014 New Indian Line Up.

1-Thunder-Stroke-111--right-side-12Thunder-Stroke-111A much larger crowd than usual on Daytona Main Street. All bikers gathering in & around the Dirty Harry’s bar for the very exciting unveiling of the new Indian Motorcycle engine to power the upcoming line up. And I must say, for me, my fellow media members and the public present at this event a terrific surprise. I must say that the Indian team succeeds way beyond my expectations in honoring the past to power the future. The all-new 111-Cubic Inch V-Twin Power Plant Unifies Iconic Past and Advanced Engineering and is another critical milestone in the company’s drive towards a full launch later this year.

0Thunder-Stroke-111It is quite remarkable that this Thunder Stroke 111 is born less than 2 years (April 2011) after the acquisition of Indian Motorcycle by Polaris Industries. It demonstrates the unprecedented commitment of time, resources and passion that Polaris has put into the design this the all-new power plant. The goal was to capture the iconic design and styling aspects of the 112-year old brand’s most historic models and fuse that heritage with state-of-the-art technology and progressive design elements. The new design reflects an unparalleled investment into researching the complete history of Indian Motorcycle power train development, including the review of volumes of historical documentation, miles of riding vintage motorcycles, and studying and dissecting a broad array of legendary Indian Motorcycle models.

With parallel pushrod tubes, finned heads, down firing exhausts, left side air intake, and the proportions and layout familiar to Indian Motorcycle fans around the world. The 1948 Indian Chief was an inspiration for designers.

    Love the gear drive cams! Harley take note, we don’t want a twin cam!

    If you only have one chance to make a first impression – – I admit I’m impressed. After years of being disappointed by HD whenever they launch a “new model’, this motor is the real deal. Indian has teased me enough so that I look forward to Cyril’s posts whenever he reveals the complete bike. BTW, nice scoop Cyril. (Can’t understand why Polaris hooked-up with the Wolfe picker-dude though. That guy just screams fake to me; not a good association IMHO).

    Beautiful motor. Congratulations to the Indian staff for retaining classic Americana styling and ethos. I’m definitely looking forward to the new bikes. As for the nay sayers I am at this moment putting my hand up to my forehead and making that “L” sign at you……

    PS. That motor video blew the doors out. Really great presentation.

    @ McGillicutty, if you were a fan of his show you’d know what a genuine Indian aficionado he is. No spoksperson will be all things to everybody but it’s hard to argue the authenticity of a guy with a popular show whose spent a couple decades hunting for those Indian “barn finds”. He’s a bit of an oddball, but he is popular and his love of all things Indian is real…At least they didn’t hire Danica Patrick and Paris Hilton to sex it up pretending they get aroused at the mere sight of some ad product.

    Certainly good looking. Some really good comments too, but was this topic about the new Indian motor or blah-blah HD? If you aren’t a fan then leave it at that. All you loudmouth cheerleader types detract from the quality of Cyril’s site.

    Anybody know if this is direct injection like the cross country? Engine looks great but the air filter had to go.

    Bringing back the HD-vs-Indian rivalry would grab a bunch of attention.
    Great move for the industry…. “Leverage The Legacy”…. Win-win all the way around.

    IMHO any way…

    A feat of engineering to have kept the vintage feel to this motor and made it a performer as well. I tend to be more aesthetically bent than most, and the first thing I noticed was iconic native american shapes throughout. Arrowhead, hatchet etc….. subtle but apparent.

  12. 12 Lyle Mar 14th, 2013 at 8:29 am

    I know Polaris would do it good. I’m still trying to see where the similarities to the X-Wedge are? Indian used twin cams and parallel push rod tubes well before there ever was the S&S company. And Indian always had a smaller primary cover than Harley.

    The Harley Killer

    Best looking new motor out there

  15. 15 Tod Apr 12th, 2013 at 5:30 pm

    The big question that you are all dodging, new rear plunger and sprung seat? I’ll have one.

  16. 16 Rod Jun 5th, 2013 at 8:17 am

    I used to own a Harley. I understand the “hook-line-and sinker” Harley owners give them. That being said…time to quit bashing every bike that shows the potential to give HD a run for their money. Old technology vs new, more efficient technology. Do the math and have an open mind. Welcome to Indian and Victory – both a breath of fresh air.

  17. 17 John Jun 11th, 2013 at 8:18 pm

    Yes they need to put this in a cheep bike to rebuild the brand. But for 12 or 14 grand your only going to get a motor. If they take the same motor make it a 600 cc size and put it on slim bobber. They maybe would have a 15,000 dollar bike that people would take a chance on.

  18. 18 Scott Aug 1st, 2013 at 7:31 am

    I’m hoping it’s as easy relatively inexpensive to get big (yet rideable) power gains like the Freedom 106– Hopefully Lloydz will start whipping up their magic…
