You think you’ve seen the biggest, baddest, meanest machines? You think you’ve seen them all? The most ominous ones there are? Then try and chew on this! The Leonhardt Gunbus – a monster of a motorcycle, quite literally. This would make a Triumph Rocket III look like a toddler with a candy in its hand.

Without wasting much time, let us give you the vital stats first – its powered by a, wait for it, 6.7 liter 45 degree V twin with 350 horses and 710 nm of torque produced at 1900 rpm. All of it is functional – you can ride this thing, legally, if you have a heart big enough and a pair of family jewels tough enough.

Standing at 3.47 meters length, the GUNBUS 410 can rival many a car for size. A well-balanced design when looked at as a standalone product, the Gunbus menaces you with its girth the moment you put a rider on top, and things in perspective. Made of steel and aluminium the concept demanded great mechanical and technical expertise, but Leonhardt with its expertise in engineering, pulled the feat in style.

We wouldn’t dare ask the acceleration and top speed of this mammoth, for we wonder whether one would ever dare to take this beast to those limits. However, if you fancy riding this one you’ll have to shell out no less than $3.5 lakh. Add to it the duties and transportation costs, and you’re looking at an amount that should be in the region of $ 5 lakh (or Rs 3 crore)
