Being retired has its perks beside not having to report for work every day. Being able to take spur of the moment trips is one of them. Spending most of my career as a Machine Tool Builder, I find learning how things are built interesting. A few days ago, I got to thinking, Cobra Moto the builder of the best, most state of the art youth 50cc and 65cc motorcycles in the world builds their bikes at their facility in Hillsdale, Michigan only 2 hours away from my home near Niles.
I sent an email to Sean Hilbert, the President of Cobra and asked him if it would be possible for myself and a few other old retired guys to get a tour of their facility to see how their motorcycles were built. Sean graciously extended an invitation. My thinking was it would be a nice outing for myself and 3 other retired buddies. All of us were motocross racers back in the day and keep up with the sport today as well and still ride motorcycles. Three of us are former Machine Tool Builders and one has his own welding and fabrication business.
The ride to Hillsdale and the Cobra facility was a nice two hour ride, combined with a stop in Coldwater for lunch, the shop tour and a two hour ride home made for a great afternoon. The temperatures were in the 60's and there was a bit of rain spitting but not enough to really get anyone wet.
Sean met with us and brought us up to speed on the history of Cobra motorcycles and explained how he became involved with the brand. With that as a foundation he lead us into the production facility. He showed us one of the original models from the first year of production then lead us to where the new electric bikes were going through final assembly.

The gasoline engine assembly area was next and we watched a builder carefully putting an engine together, piece by piece. Cobra builds all of their engines in house. There are no assembly lines at Cobra. Most motorcycle manufacturers use an assembly line as a means to streamline assembly which allows unskilled workers to add a component or series of components in the minute or two as the work piece passes by their station. The engine builders here at Cobra are craftsman who have an intimate knowledge of each component and hand build each engine from start to finish. Myself, being a Machine Tool Builder, can appreciate that since that's the way we built machines that our companies sold for hundreds of thousands of dollars.
Next was the final assembly of the 50cc motorcycles followed by the 65cc assembly area. Again, there are no assembly lines here. Various sub-assemblies are put together at other stations, again by skilled craftsmen/craftswomen and brought to the final assembly stations where a single worker will fully integrate all of the components into a complete finished motorcycle. These motorcycles are truly hand built.

Next Sean took us through the machining area where we saw an array of CNC machining centers turning out parts. Sean explained many of the improvements in manufacturing they've incorporated to improve quality and increase productivity which helps to keep the price of the machines in line. He showed us the dynamometer where they test the engines, the Quality Control area with it's coordinate measuring machine and other test equipment. They even have a test chamber that, if I recall correctly, can be adjusted from -30 to +150 degrees to test machines/components at extreme temperatures for extreme environments. R&D in ongoing and always moving forward at Cobra.

Cobra also designs and builds their own, Card Performance brand of suspension. High end components that offer greater adjustability and tuneability over what's available even by the leading Japanese suspension companies. They also design and build all of their frames in house as well. Clutches, transmissions, braking systems, levers all designed and built in house. I found that amazing! These are truly American made motorcycles!
Cobra has diversified and has branched out into other areas including building an improved portable water pump used by Firefighters. Sean showed us a portable pump that Firefighters were using until recently that weighed 75# and the one that they've created that pumps out a higher volume of water but only weighs 45#!
They also are working with the US Military supplying propulsion systems for unmanned aircraft (drones) both fuel injected and hybrid units. He showed us several different configurations from single cylinder air cooled units to 3 cylinder liquid cooled, fuel injected engines that can be held in the palm of your hand. The cylinders and crankcase are both 3D printed from an aluminum alloy. Very cool stuff indeed.

I don't want this to sound like a commercial but I came away really impressed with my visit! Cobra's tagline "Champions Start Here" is more than a tagline, it's a documented history. If you look at the riders who started on Cobra's it reads like a who's who of AMA Champions. Names like Millsaps, Baggett, Izzy, Canard, Durham, Tomac, Sipes, Dungey, Alessi, Cianciarulo, Webb, Osborne, Bell, Bowers, Chisholm and Hackley all raced and won on Cobra's early in their career. Champions truly do start here!
Awesome write up.
They really are great bikes
That was a fantastic write up. Good for you guys. I'm a little jealous. I would love to do that tour!
Nice write up and sounds like a good time for you guys, props to Cobra for making themselves available.
Really cool little bikes and operation.
Interesting on the drone motors, I see Rotax have been supplying them to a lot of people (some definitely not favourable by our standards) so cool to see an upstanding alternative 👍

Are they actually Chinese motors touched up in Michigan?
Nice
FilthyGrungy asked "Are they actually Chinese motors touched up in Michigan?"
Answer, NO! These engines start out with castings made locally or 3D printed from aluminum alloy in house at Cobra. They are all machined in house. I didn't see any pistons being machined so I don't know if they machine their own pistons in house or if they buy them from a supplier like Wiseco which might make sense. Anyway, I can attest to the fact that the engines are 100% made by Cobra in house. I saw plenty of raw castings as well as in process castings that were going through the machining process.
Very cool, thanks!
Awesome write up and thank you for sharing!
I wanted a cobra so bad. Dad went with ktm’s then polinis for some reason? Such badass little bikes.
Not to change the subject but I would truly like to know how many SX/MX champions rode a PW50/80 as their first bike.
Probably everyone since 1981.
Any info on the possible 125 ?
I asked Sean about that, asking him if they had any plans to produce larger motorcycles? He said that, yes the interest is there, however they understand their position in the sport. Young riders come up through ranks and as they develop and start to show promise their equipment must improve as the young riders place more demands on it. Parents may choose to provide better equipment which likely means Cobra motorcycles. Elite equipment for elite riders which helps the riders get the best out of their talents.
You typically don't see a mid-pack, weekend warrior riding a Cobra, you'll usually see them on a more production based Japanese or Austrian built bike. You typically see the more elite riders on the Cobra brand bikes. When these elite riders establish themselves and show promise as a potential upcoming prospect, they get snatched up and signed to factory contracts by Team Green, Orange Brigade, Blu Cru, etc. Sean said that their elite riders get snatched away from them and being a small company they can't compete with the Big 5 by extending contracts to the best elite riders. I'm not quite sure if making larger displacement motorcycles would make sense or not for Cobra.
If you think about it, the Cobra motorcycles are the closest thing to having a factory bike that most kids will ever have an opportunity to ride. Both the Japanese bikes, YZ & KX, made in Japan and the KTM, Gas Gas & Husqvarna bikes, made in India, are assembled on assembly lines. Assembly lines allows factories to hire unskilled workers to perform simple tasks to attach components to a motorcycle chassis as it passes through their work station. The assembly line workers only need to know how to perform their assigned task and most do a pretty good job. I'm not knocking assembly line workers. Assembly lines are not bad. They keep the cost of things we buy lower and allow for mass production.
As I mentioned previously, Cobra doesn't use assembly lines. Let's take a look at how Chase Sexton's or any other factory riders bike is built. Honda supplies Chase with an engine guy, a suspension guy and a mechanic to intergrade all the components together and do the final assembly of his race bike. That's exactly how Cobra builds a motorcycle.
What's amazing to me is the Cobra motorcycles don't cost much more than a comparable KTM. Prices I found online show a 2023 KTM 65SX listing for $5499 and a 2024 Cobra CX65 listing for $5898.
Getting deep in here
That's a bummer they want to stay small. If they had a decent 125 they'd have a new market segment. Vets and guys who don't want an Austrian bike.
Rick,
Thanks for making the ride over...We always enjoy giving folks a tour of our plant. For anyone that is interest in doing the same, all we ask is that you contact us ahead of time, so that we can plan properly.
