Mark “Makr” Atkinson has felt the “need for speed” since he was a small child, first attending Speed Week at the Bonneville Salt Flats in 1971 with his family. He went on to become a custom builder of race components and cars before eventually finding his true love: motorcycles.

Check out more of Makr’s story below.

Video transcript: Company of Enthusiasts: We’re Into Custom Bike Engines

I’m Mark Maker Atkinson. I’m into creating. So my name’s Mark Atkinson. My friends call me Maker.

We’re in Woods Cross, Utah, just north of Salt Lake City in an airport, and we’re in an airport hangar. And this is my shop. So come on in. Let me show you around.

So I have a CNC machine shop, and I do mostly custom automotive motorcycle stuff. I’ve done, you know, a few cars, but motorcycles are mostly my thing. Probably the best known one is the BMW* Alpha, which was very artistic. It’s not necessarily much of a rider.

I mean, I’ve got all sorts of bikes here that are riders. But I wanted to do something that really stretched my own abilities, and what I saw a motorcycle could be. And that Racer-X electric bike is kind of the same way. I approached it from the standpoint of what I would do if I didn’t have any idea of what a motorcycle was supposed to look like.

So, yeah. It was just a fun project. For the most part, we have CNC equipment. And this is, in fact, right now set up — setting up doing these feet, which is a JackDaddy jack for those razor side-by-sides.

If you have a flat tire or you need to change tires, you just basically drive up on it. So it’s just super simple and easy and kind of an elegant little piece. The other thing we make over here is I have a piston, a really cool two-piece two-stroke piston. It has a trapped ring that doesn’t allow it to expand all the way.

Like a normal ring that’s kind of floating around, my ring doesn’t do that. It’s trapped, and it doesn’t allow it to go all the way out. It’s kind of an ongoing project. It’s what I’m running in my land speed bike.

Hopefully, over this speed week, we’ll really prove how well they work. So Speed Week on the Bonneville Salt Flats 2019 starts really today. It rained last night, so my guess is that we’re probably going to be delayed a day in racing because I think it’s really wet out there. Bonneville Salt Flats, I race every year and have — well, I mean, my first year on the salt was 1971, so I was just a little teeny kid.

It was a family affair. So I’ve been racing this motorcycle since ’06. So what are we talking about, 13 years? This is a mid-’70s Yamaha* RD400, and so I’ve kind of stuck with racing these and building them.

Obviously, I’ve got one, two, three, four of them. And, basically, I’ve just got to do a little bit of wiring and put the tank on and we’ll be ready to go. This particular engine I build entirely myself. The case is stock.

It keeps me in my class. I have to keep the stock case. But crankshaft, connecting rods, pistons, the entire engine, everything is all manufactured by me. So I designed my own assembly, and the first year I built my own was 2013 and went out and it ran like a top, set a record at 140 and a half or whatever.

And now this is now on the third revision of my particular builds. And this thing makes world-class power. I get on my dyno 140 horsepower out of this little 500cc engine. The Bonneville Salt Flats is kind of a surreal environment.

The scenery and everything it’s just — it’s just mind-blowing. We’re out on the famous Bonneville Salt Flats, 2019 Speed Week. One great thing about and why we race there is — besides that it’s a nice flat surface is it holds the moisture up at the surface. The thing about land speed racing is that you don’t just go that speed.

You have to hold that speed for a full mile. You can’t keep a rubber tire cool enough on any other surface. Even dirt gets too hot. So the salt is just kind of the perfect surface.

I think that the racing is just the cherry on top. I like the engineering and the building part of it. That’s really where I get the kick out of it. You know, it’s the freedom and the ability to do anything.

I don’t — I don’t have any limitations other than what’s in my mind. [ Music ]

Self-taught in fabricating, welding and painting, Atkinson’s talent and experience have produced some of the most unique and sought-after builds on two wheels. Below are some of his builds that headline articles, reside in museums and can also be seen in the video above.

BMW Alpha

BMW* Alpha

Atkinson’s most famous build started as a computer rendering his father posted on Facebook. After contacting the Turkish designer, Mehmet Doruk Erdem, with no response, Atkinson decided he needed to build the bike.

He envisioned traditional classic style with go-fast streamliner lines. Based on the BMW K75 Triple, an elegant rolling chassis highlights the Alpha, with components fabricated from scratch by Atkinson.

Racer X

Racer X

Seeing electric bikes as an opportunity to push the limits of design (while not having to work around a gas tank), Atkinson decided to think outside the tank.

“What would I build if I had no preconceived idea of how a motorcycle is supposed to look?”

Mark Atkinson

Using an FIM record-holding motor inside a unique aluminum X frame, this one-of-a-kind bike was named “Racer X” after its unique shape.

Makr Atkinson RD400

RD 400

Atkinson takes to the Bonneville Salt Flats in a mid-70s Yamaha* RD 400 that he built from scratch. Atkinson manufactures the entire engine himself, minus the stock case he must use to fulfill class rules.

In 2013 he built his first assembly and broke a world record in that same run. On his third revision of the engine, Atkinson set out in September 2019 to once again attempt a land-speed record. Unfortunately rain forced the cancelation of Speed Week, forcing him to wait another year to defy the clock.
