The Yamaha SR400 Cafe Racer: is it made by aliens?

The Yamaha SR400 Cafe Racer: is it a machine made by aliens?

Is it a Concept bike? Cafe racer? Is it a Racer? Or is it a Space ship in disguise?

Whatever it may be, Markus Pintzinger from Omega Racer claims his Sunmaster 14 SR 400 Cafe Racer isn’t one but in a world where people are quick to label unusual things, there’s no escape for him and he has stopped arguing about the classification of his bike is.

Built in Thailand, Markus Pintzinger started out with the SR400 as his base bike platform to start this project. Sorry, conspiracy theorists but this bike was made by a man with a dream and enough determination to see his project see the light of day.

The most obvious feature on this Yamaha SR400 Cafe Racer is the aluminum fairing that encompasses the majority of the front area on this bike.

This is a totally hand built feature which makes it more impressive.

Now, the front fairing may have added some noticeable bulk to the entire bike but that doesn’t mean the builders got lazy. In fact, a lot of effort was placed on keeping everything slim.

Everything was hand built from scratch so you’re going to have a hard time looking for these exact items on any manufacturers’ product catalog. Much emphasis was put into achieving a slim profile.

So, if you view this bike from the top, you’ll see that it looks like a bullet with a tapered end.

The Yamaha SR400 Cafe Racer’s frame received very minimal modifications.

Most of the components found in the rear section came from Omega Racer’s catalog.

This includes the polished aluminum swing arm that, for the time being, you can only order from Markus’ company. Ohlins shocks were put in place to give it a comfortable ride.

Because the Yamaha SR400 Cafe Racer had to make sure it had the power to back up its racer looks, Markus completely rebuilt the engine and then fitted a Keihin FCR39 Carb to give it that much needed “oomph” each time he throttled the bike.

Although this bike looks fancy at first glance, a more thorough examination will reveal the no-frills approach the owner took with this machine.

Up front, there is a very simple dash with toggles and switches enough to inform him about the bike’s condition as he is riding without being too distracting.

The only thing that looks slightly out of place with this racing machine is the side mirror that sticks straight up from the handlebar. But then again, if you’re going to ride your bike in Thailand, you really need side mirrors!

So is this Yamaha SR400 project bike what it really is? Or is it something off the pages of a sci-fi novel that only Isaac Asimov could have originally thought of?

Whatever the case may be, Markus Pintzinger surely has a winner in his hands as having one of the most beautiful Yamaha SR400 Cafe Racers in existence today!
