Most motorized bikes cap out at 30 to 35 MPH. With the proper performance parts, however, you can see increases in top end speed up 40 to 50 MPH.
So if you need more speed out of your engine than you're getting, it might be time to swap out some parts. Thankfully, there are plenty of high performance upgrades that will give you the desired top end speed you're looking for.
Whether you're thinking of hitting the racing circuit or just want to get that maximum speed while riding, we know exactly what can give your bike's engine the improved top end speed you're looking for.
Should You Install 2-Stroke Performance Parts on Your Motorized Bike?
Maybe you’re comfortable with the speed you’re getting out of your 2-stroke motorized bike. Perhaps you just have a short commute to work or the grocery store and you don't need anything more from your bike. If that’s the case, you might not need a super powerful bike. That said, there are plenty of reasons motorized bicycle riders want — and in some cases need — to achieve faster top end speeds.- Motorized Bike Racing — 2-stroke engines are massively popular due to how customizable they are. You can take a stock 2-stroke engine and swap out the majority of its small parts to turn it into a high-speed performance engine. As such, the 2-stroke motorized bike racing circuit has a large community of enthusiasts. If you’re looking to join a local racing club, you’re going to want to install 2-stroke performance parts on your motorized bicycle so you can leave your opponents behind.
- Off-Roading — Just like 2-stroke motorized bikes are great for racing, they also make good dirt bikes. If you want to get a bit more top end speed while taking on dirt roads and other off-road obstacles, installing high performance parts on your 2-stroke engine will give you exactly what you’re looking for.
- Tackling Long Commutes — A motorized bicycle with high top end speed means you can get from point A to point B a lot quicker. If you’re not looking for an adrenaline rush and just need an improvement in speed to get across town to work or school, high performance 2-stroke parts are the right call. Just make sure you’re following local traffic regulations and are familiar with your state’s motorized bike laws.

If you’re looking to upgrade your motorized bike’s speed, you’ll definitely find a high performance component on this list that’s sure to fit your riding needs and give you that boost you can feel when you hit the throttle.

36 Tooth Rear Sprocket — Decreases Drive Ratio for Faster Top End Speed
If you want an instant dose of extra top end speed out of your motorized bike, all it takes is a simple sprocket change. A 36 Tooth Rear Sprocket is a great choice because it’ll allow you to reach faster speeds on your motorized bike with no issues — and it's one of the simpler upgrades to install.
Typically, larger sprockets with more teeth will give you increased torque at the cost of top speeds. Alternatively, a 36 Tooth Rear Sprocket — which is relatively small with a lower number of teeth — will give you lower torque, but with the added benefit of faster top speeds.
Though it’s decent on its own, a 36 Tooth Rear Sprocket really makes an excellent companion if you pair it up with any of the other 2-stroke performance parts on this list.
2-Stroke Upgrade Features:
- Higher top end speeds than larger sprockets
- Compatible with most motorized bikes
- Easy installation
