The World’s Biggest Motorcycle – Meet The Leonhardt Gunbus 410

HFL -

It may have been around for a couple years but we’re still none the wiser as to why the Leonhardt Gunbus 410 was ever built or who it’s actually intended for, or if one has ever been sold.

The German manufacturer claims this massive motorcycle – the world’s largest – is road legal, but to our mind it will either make you look like a tiny human being from a distance or just plain weird close up.

The Leonhardt Gunbus 410 dwarf’s what should be viewed as a large motorcycle.

Leonhardt, based in Eppingen, is sticking to its guns and describes its creation as ‘the most perfect combination of performance potential and a well-balanced design’.

At 1,433 lbs it is immense. Overall length of the Gunbus is 11 foot with a seat height of 30 inches. There’s a V-twin engine of sorts, but because this is no ordinary motorcycle and according to Leonhardt it apparently produces 510 lb.-ft. of torque and a claimed 350 hp.

The 410 in the Gunbus name refers to the fact the engine has 410 cubic inches or a cubic capacity of 6,728cc. There’s a three-speed transmission and a reverse gear just in case you find yourself in a tight spot with the Gunbus and need to back out. It might take you a couple of hours though.

As you would expect the Gunbus rolls on massive rubber with a 38-inch front tire and a 42-inch rear.

Leonhardt is especially proud of the fact that the Gunbus 410 is entirely made in-house and assembled by hand and underlines this by stating that: “All components of this motorcycle are most precisely manufactured in solid manual labor.” Yeah we have no idea what that means either.

The good news is that if you really, really want a Gunbus 410 you can buy one now, but you will have to part with an immense $350,000.

We’ll leave the last word on this entire matter to Leonhardt: “It is the classical, clear and elegant shape of this motorcycle in prefect harmony with its distinctive, mechanical design which lets the Gunbus 410 appear to be an especially charismatic vehicle with an irresistible visual effect. And moreover, since the creation of Gunbus, terms such as size and performance have been given a completely different meaning.”

The Leonhardt Gunbus 410 is absolutely massive.

So there you have it. Big bike. Big money. We’re still none the wiser.

    I’m just curious how it’s steered — is that some kind of power steering setup behind the headlight?

    • ThruTheDunes

      Aw, c’mon, you know Ride apart is going to make us wait until they have one in their long-term fleet ;-)

    • Justin McClintock

      Can’t say for sure about the steering (although I believe it’s surprisingly conventional), but that setup behind the headlight is the suspension for it’s girder front end.

  • http://www.motopraxis.com/ Aakash

    I see where the “bus” comes in, but where are is the “gun”?

    • Jay Hartley

      Must be the sound, which I imagine is like artillery shells being fired from a battleship.

  • kevin

    The two wheeled equivalent of the massive pickup truck for insecure men? At least it’s visually more interesting than a Boss Hoss.

    • Mykola

      If the Boss Hoss is an F-450 Platinum, the Gunbus is an International CXT. Ridonkulous.

  • Brian

    I would be curious to ride it just for the heck of it. I think of machines like this in the same way I think of weird one off pigeon holed weapons built for no clear purpose. This is an answer to a question that no one has asked. That doesn’t mean it isn’t cool or neat or an exercise in engineering talent, it just isn’t mainstream. It is the freak that walks into a room and everyone one stops what they are doing to turn and gawk at. I think it would be interesting to sit off to the side and see peoples reactions to this rolling into town during one of the big bike week events, like Daytona, Laconia, or Sturgis.

    • runnermatt

      Sturgis, definately Sturgis. If I win that lottery I’ll buy one of these and take it to Sturgis. I think that would be the only way I would ever go to Sturgis.

  • Justin McClintock

    I’m waiting for the 510 since this one is clearly not large or exclusive enough.

  • Dan Kearney

    Think getting caught under a Goldwing is bad, imagine a parking lot slip-up with this monster! 8 foot long arms would be helpful in order to keep the turning radius down below 35′. Ha!

  • Send Margaritas

    I’d like to see someone drag a knee on this motorcycle.

    • Jeremy

      I’d like to see someone turn this thing.

    • Dyler_Turden

      I think they are more likely to drag their face. haha

  • Richard Gozinya

    I kind of want to ride it. I wouldn’t want to own it, but to ride that gargantuan hunk of two wheeled perversion just once would be a special kind of fun. Not fun like a CR700P, more the stupid kind of fun, like shooting collectible plates with a pellet gun.

  • stever

    I am so ashamed to be an American right now.

    • luxlamf

      It’s German, are you Ashamed that a USA Co didn’t make it?

      • eddi

        He though only Americans were that crazy when it comes to bike design and the worship of the holy cubic inch. After Honda’s 130 mph lawnmower, I think this sort of crazy is universal.

        • luxlamf

          Well He is being Very American in that starts talking about something without actually reading the article 1st, Thats American of him.

          • http://www.racetrackstyle.com/ Racetrack Style

            Can you write more generalizations?

            • luxlamf

              Yes I can, I also take credit for my posts, unlike Postie here who is now back tracking and pretending he was “Joking”. Come one Postie own up to it, You posted it it’s yours.

          • stever

            You’re really stupid. I joked that I ashamed that America didn’t build the biggest motorcycle.

            • Jason Paul

              I knew what you meant. You’d think we’d have come up with this, in light of Boss Hog and all, but we have clearly been 1-upped. I hang my American flag trucker hat in shame.

          • stever

            but what’s more american than showing up to a webpage where people speak a language you don’t understand that well and then insulting strangers because you can’t understand what’s going on?

  • Terry Hershner

    I’m pretty sure mine is bigger. 150 pounds lighter, but definitely longer. https://www.facebook.com/lifeoffthegrid/posts/507623722666770

  • Harve Mil

    I imagine a high side with this thing could propel you over the safety fence and into the skybox.

  • lysdexia

    I’ll stick with my Super Cub.

  • Mitchel Durnell

    I think this project catalyzed around the motor, which is two jugs cut off a radial airplane engine.

  • chad west

    Can it even corner?

  • Mr. White

    Ummmmm…what’s the point?

    • eddi

      I think the point is engineers gotta engineer. I assume some brave volunteer was strapped onto the beast and fired down the Autobahn at some point. If they sucessfully paved over the scorch marks it was considered a proof that the bike was a viable concept.

      • Mr. White

        Just because you CAN, doesn’t mean you SHOULD.

        • eddi

          What are you? Sane and sensible? :-) I’ve known a couple of people like this; an idea is either physically impossible or it’s a work in progress in their garage/den/ lab.

    • Denise Leitzel

      It’s the Hummer of motorcycles.

  • Robert Horn

    Finally: The Prius resistant motorcycle! Any Prius driver that attempts to cut it off will merely get punted into opposing traffic. Cool!

    • eddi

      Heck it looks like it could flatten an old-school Lincoln Continental.

  • Ducati Monster

    Faciarossaegunbusiphobia; the facial phenomenon associated with the fear of dropping this bike in front of a huge crowd.

    I’d love to see the worlds biggest guy (not tall & lanky & not obese but proportionally correct & fit) riding this monstrosity. Any candidates?

  • Mr G

    You’d never want to turn this thing around on a steep hill.
    If it fell over you’d need a tow truck to pick it up!

    • eddi

      Assuming it didn’t land on you. In which case the EMTs should bring a spatula.

  • appliance5000

    Are they making aftermarket pipes yet?

  • runnermatt

    The first cruiser that doesn’t need a faring or windsheild for wind protection.

  • Timothy Gammey

    can I get it with ape hangers?

    • eddi

      Those are ape hangers. They’re just horizontally oriented. I suppose some mad genius could weld up some clip-on version.

  • Blixa

    Looks like the vehicle of a Final Fantasy hero.

  • David Magallon

    I want to see a movie with Hellboy riding this.

  • Guest

    The Guiness World Record folks seem to disagree:

    http://www.guinnessworldrecords.com/tallest-rideable-motorcycle/

    • eddi

      Bigger, yes. But the tires are wide enough to keep it stable without rider input. That leaves room for a long boring debate degenerating into a flame war. I’ll just be leaving now.

  • charlie

    I wouldn’t want to lay that sucker down

  • Guzzto

    Dude looks like the cops from THX1138

  • Chris Cope

    Because sometimes a guy’s penis is so small that a Harley just won’t compensate.

  • Ayabe

    I’ll wait for the version with Whale Penis leather accents.

    There are also rumors of a diesel version, runs on liquified koalas.

  • http://www.racetrackstyle.com/ Racetrack Style

    I just want to hear it idle & I think a complete bike around it is necessary for that complete experience.

    • Tim Watson

      This might give you an idea…. http://www.youtube.com/watch?v=tG-MSRjgzhY

      • http://www.racetrackstyle.com/ Racetrack Style

        Thanks! Nice find. It was very smooth sounding for such a large 2 cylinder motor but it was a bit of a let down. I was expecting a deeper sound. The cooling find are incredible

      • frankfan42

        Amazing engine. It really does look a lot like they use the jugs from a couple of old radial engines, amazing stuff.
