2-stroke motorized bicycle rider.
Even if you have your dream motorized bicycle assembled and ready to go, you may notice that it doesn’t perform as smoothly as you’d like. Sure, you’re getting the speed and power you want out of it, but you might also experience a bit of a rough ride. That can happen, especially when you take into account that you have a powerful 2-stroke engine pushing your bicycle forward.

If you want a smoother ride out of your motorized bicycle, you’ll be glad to know that there are 2-stroke performance parts that can give you exactly that. Some parts will help eliminate your engine’s vibration, while others will create a smoother motion so your rides aren’t as rough. We’ve compiled a list of the best performance upgrades to ensure a smoother ride on your 2-stroke motorized bike. Not only will these components give your motorized bike smoother performance, they’ll also provide more comfort and even a bit of added safety on the road. But first, let's talk a bit about why a smoother ride is about more than just comfort.


Benefits of a Smoother Motorized Bike Ride

2-stroke motorized bike used for commuting.
There are more benefits to smooth motorized bicycle performance than you'd think. Let's be real here: Comfort is a huge factor, and it's an important one. You don't want to be uncomfortable whether you have a long commute ahead of you or you're just going out for a joyride. Quality comfort aside, there are a few more reasons why you should get a smoother ride out of your motorized bike:
  • Better Performance — Better ride quality often means you'll get better performance out of your motorized bike. This is because a lot of high-performance parts that help create a smoother ride also reduce engine vibration and overheating. As such, an engine that runs smoother will also perform better, which is great whether you use your motorized bike for commuting, off-roading, or racing.
  • A Safer Ride — If you've got a shaky engine, different components are likely to rattle and vibrate a lot more. This could lead to a chain snapping off or another component becoming damaged, which could lead to injury if you're not careful. Not to mention, you have more control over your motorized bicycle when it performs more smoothly, which makes it a lot safer to operate.
  • Less Wear and Tear — A 2-stroke motorized bike that vibrates and bumps less than normal will typically experience less wear and tear than normal. Over time, too many rough rides can loosen or break engine studs, mounting hardware, and other parts, leading to excess wear on the engine and bike. If your bike performs better and smoother, you'll deal with a lot less maintenance and replacements in the long run.

As you can see, there are a benefits to a smoother motorized bicycle ride beyond comfort (though that's an important one, too). With that said, let's take a look at some of the best motorized bike parts you can equip your ride with for a smoother-running 2-stroke engine.

BBR Tuning 2-Stroke T Belt Drive Transmission Kit — Smoother Drivetrain

BBR Tuning 2-Stroke T Belt Drive Transmission Kit.Looking for both a smoother and quieter ride? If your motorized bicycle is making a lot of noise, you should consider the BBR Tuning 2-Stroke T Belt Drive Transmission Kit. 2-stroke engines are typically quite noisy — this is due to the chain drive that these motors use.

Chain drive transmissions can also require some maintenance over time. Thankfully, a belt drive transmission alleviates those issues. Instead of a chain, this BBR Tuning upgrade uses a belt with its two machined aluminum gears. The result is a quieter, smoother, and more comfortable ride. With this T belt transmission, you’ll notice a smoother increase in your engine’s torque, so acceleration is gradual rather than sudden when you twist the throttle. Plus, it’s way quieter than a metal chain and doesn’t accumulate as much dust, dirt, or debris. T belt transmissions require much less maintenance than chain drives, too, so you won’t have to deal with fumbling with a chain just to clean and lubricate it.

This transmission will work with a lot of different motorized bike builds and 2-stroke engines — it’s compatible with both 48cc engines and 66/80cc engines. It can also be used with a sprocket clamp assembly and mag wheel setup.


  • Eliminates noise you’d get from a chain drive transmission
  • Smooth, gradual acceleration versus sudden increase
  • Easy to install

BBR Tuning Racing Series DIO Cylinder Body & High Performance 21mm OKO Carburetor Assembly — Smoother Air Intake

BBR Tuning Racing Series DIO Cylinder Body & High Performance 21mm OKO Carburetor Assembly.The BBR Tuning Racing Series DIO Cylinder Body & High Performance 21mm OKO Carburetor Assembly is perfect for motorized bike riders looking for a smoother and more powerful ride. It’s the perfect high-performance upgrade if you’re a racing enthusiast or you’re just looking for a faster commute. What sets this cylinder apart is the way it’s ported for the best fuel and air mixing.

The attached reed valve allows for a much smoother flow of air and fuel into your 2-stroke engine. Reed valves allow your engine’s air-fuel mixture to move in one direction, preventing the mixture from moving back into the carburetor. This ensures that the combustion chamber is reloaded with only fresh air-fuel mixture, allowing for smoother operation even if you’re hitting top speeds. In addition, the “D” slide carburetor provides more effective jetting, airflow, and fuel atomization increases.

This 2-stroke carb is versatile, as well — whether you have a high-performance muffler or stock muffler, this upgrade will work with it. So if you’re looking for higher speeds, more torque, and smoother performance, this carb is as compatible and as powerful as it gets, and it makes a great upgrade for your 2-stroke racing engine.

Note: In order to use the cylinder included with this set, you’ll need a 2-stroke dual window piston, which is next on our list!


  • More power, torque, and speed
  • Better airflow and fuel-and-air mixture
  • Compatible with stock and high-performance mufflers

BBR Tuning DELUXE High Performance Expansion Chamber — Smoother Exhaust Flow

BBR Tuning DELUXE High Performance Expansion Chamber for 2-stroke engines.If you’re experiencing a bumpy ride on your motorized bicycle, your muffler could be the problem. The built-in baffle in most stock mufflers tends to hinder your bike’s performance because it limits the airflow coming out of the engine. Thankfully, the BBR Tuning DELUXE High Performance Expansion Chamber is baffle-less, allowing the max amount of airflow out of your engine.

The expansion chamber’s design helps circulate air through the muffler, giving you an all-around smoother — and faster — ride. With this upgrade, you’ll also avoid build-up in your 2-stroke engine. This is due in large part to the expansion chamber’s extended length, which expels more exhaust and allows it to flow from the chamber more smoothly.

In addition, the wrap-around design of the muffler means it comes up right next to the engine, so you don’t have to worry about it scraping or becoming damaged while you ride. If you’re got a motorized lowrider or chopper bike, this expansion chamber upgrade is the ideal choice. That said, it still works great with other bikes — in fact, it’s compatible with practically every motorized bike and 2-stroke engine!


  • Boost in speed thanks to increased airflow
  • Wrap-around design keeps muffler from dragging and scraping
  • Compatible with most 2-stroke motorized bicycles
