Nope. I am pretty sure Hilderbanrd and Wolfmuller produced the worlds first production motorcycle between 1894 and 1897. Internal combustion engines of 1500cc. They built steam powered one's before that, but the Motard which went in to production, was internal combustion, and built five years before Laurent & Klement. They also built 2000 of them, or about ten times more than the L&K original run of their 1899 machine.

@M Bacon Thanks for explaining to the best fan!

These suck air through the petrol tank where it picks up a rich mixture. The rest of the parts lean out the mixture the required amount and also control the amount of throttle opening. There's a few operations required to ride this bike. And putting a lid on the fuel tank is required after riding. There are two cylinders with handles on. I guess one with the variable holes on top adjusts the mixture ratio, the other is the throttle opening, hence speed.

@M Bacon yes , there are multitude designs, including one's with wicks. I Googled these fuel tank types, and deduced from the appearance. I am a motorcycle mechanic by trade but never worked on these old bangers. Though I wouldn't mind a ride on one.

@M Bacon Oh, I fully agree with you there!
