My first pocket bike experience...


Guy on MTX Pocket Bike

I just got a new motorcycle. It was spankin' new, sporting 3 spoke rims, racing slicks, and shipped in my favorite K-dub green. It's not really a motorcycle. It's a mini moto. That's European for a one fast ride. Powered by a custom-built 47 mL race motor, this puppy screams. Stock? About 30 with a 200 lbs guy on it. Souped up? 50 mph plus.

Unadulterated torque. Amazing handling on the turns, making you lean in just like on the real thing. Gripping acceleration. One thing I can say is this pocket bike is definitely not a toy. It's a racing machine. My buddies are getting theirs too, and we are starting up a race club by my local track in Jersey.

I've had the pocket bike for a little over a month now. People always ask me, "what the heck is this thing?" I say, "it's my best birthday present ever." They don't call them crotch rockets for nothing. These bikes are swift, they run hot, and if you mod out the exhaust, are heard from a mile away.

When I first got the pocket bike, I didn't know anything about it. A month later, I've already put on a carb kit, a rocket key, and I'm saving up for a big bore kit to make it unstoppable. Understanding the ins and outs of the engine has really made me appreciate the bike, and the mini moto sport, so much more.

Gas Poweredpocket bikes: An introduction

Gas powered pocket bikes originated as small mini motorcycles built privately by hobbyists around the world, and have since evolved to fill a specialized mini racing niche, as opposed to their original incarnation as small gas powered bikes built from spare parts in garages.

Gas powered pocket bike racing itself originated in Japan in the early 1970's on small racing circuits originally designed for go-karts. The sport began with racers using one of a kind, low tech backyard models constructed from various used parts. By the 1980's the sport had found its way into many parts of Europe, and shortly thereafter, Pavel Blata and other outstanding engineers had begun the design and manufacture of ultra-high quality racing gas powered mini bikes. These became the first professionally engineered gas powered pocket bikes. By the 1990's the sport was spreading across the continent like wildfire, and a lot of pocket bike racing clubs were founded in several countries, with the Swiss at the head of the pack in terms of quantity of organized races and racing teams. Many of today's greatest Italian and Japanese full size motorcycle riders began to hone their skills at a young age due to the prevalence of gas powered pocketbike culture near their homes.

Gas powered pocket bikes in America

The sport has been slow to reach the United States, and as a result, many americans believe that the world of pocket bikes and pocket bike racing are a relatively new sport, but rest assured, the road has been well traveled. Most gas powered pocket bike models currently available in the United States today are powered by two stroke engines, generally from 39cc-110cc in size. Originally only used on private property, or country back roads, organized gas pocket rocket racing clubs can now be found in many states, with many local go-kart tracks providing the racing venues.

The future of Gas powered pocketbike racing

Gas powered pocket bikes prove to be an enduring sport due to the pure thrill of riding these little pocket rockets. Although smaller in scale than a real motorcycle, that slightness of size and mass increases the feeling of speed exponentially. Incredible acceleration and handling are the anvils on which a pocket bike hobbyist's love is forged. There's also something to be said about owning your own machine, maintaining it, and the freedom you feel on your gas powered mini bike. This, coupled with a wide price range, and the availability of after-market parts ensures that there is something for everyone, and thousands of combinations of performance parts for your bike means that almost no one will have identical bikes on race day. Gas powered pocket bikes are by far the most budget friendly way for you to get in the swing of racing real vehicles. From racing with friends, to the freedom of customization, and the excitement just before you start your bike for the first time with a new performance part, the hobby of gas powered pocket bikes is one of the most involved, and after time, your bike may just become an extension of you.

Safety Disclaimer: remember, pocket bikes are not real motorcycles, and should only be used on private property away from cars and other vehicles. They say, "for racing use only". They mean it.


As I mentioned earlier, if you have a pocket bike, you can't appreciate it to the fullest without putting on some performance parts. Here's a list of recommendations given to me for what will get you the most bang for your buck when it comes to upgrades:

Carburetor: Stock carbs on these engines are bit finicky. While they run good on a stock engine, once you start installing upgrades, you quickly exhaust the maximum capabilities of the carb. So it's a good idea to install a bigger carb from the very beginning. You'll need to get an aftermarket air filter as well, because the HP carbs don't work with the stock air box.
Exhaust: Be careful with this one. A high-flow pipe, combined with an upgraded carb, will boost your pocket bike into the extreme zone very quickly. The pipe lets the exhaust flow out easier, which helps suck more gas through the carb into the engine.
Fiberlass Reed Kit A pocket bike motor has little metal one-way flaps that let the gas/flow mixture into the crankcase (on its way to the head), but do not let it backfire into the carburetor. Laser-cut fiberglass replaces the stock metal reeds and increases engine response, and top RPM's. You get more compression per stroke, which means more POWER.
Rocket Key You need to do some engine work for this one, but considering how cheap the part is (about $12), it's well woth it. Take off your flywheel (located behind the pull start), and "advance" it forward by installing an offset woodruff key. The engine fires earlier and runs faster than ever.
Sprocket and pinion gear: If you're over 180lbs and want fast acceleration, consider changing your gearing to get more torque from your bike. You will take off faster and beat everyone around the turns. Likewise, if you are a speed fanatic and just want to go fast, you can get a larger countersprocket, a smaller rear sprocket, and turn your bike into a hyperfast bullet train.
Steering stabilizers Install a set of balance bars that reduce steering wobble. You'll be crusing just like on a large bike, you'll just get more looks like I do.
