Why Consider a 2022 Honda Grom Engine Swap?

So, why would you even think about an engine swap? Well, the stock 125cc engine on the 2022 Honda Grom is pretty peppy for what it is, but let's be honest, it's not going to win any races. The beauty of the Grom, though, is its incredible aftermarket support. There's a whole world of possibilities when it comes to engine upgrades. A Grom engine swap can provide some serious benefits, including a massive increase in horsepower and torque, letting you leave your friends in the dust. You can hit higher top speeds, and experience faster acceleration. Beyond performance, some folks swap engines for increased reliability. Perhaps the original engine has seen better days, or maybe you're looking for something that can handle more aggressive riding. Then there's the 'cool' factor. Nothing turns heads like a Grom with a completely different engine under the hood. It's a statement piece, a testament to your passion for motorcycles, and your willingness to get your hands dirty. The 2022 Honda Grom engine swap scene is booming right now, with more and more kits and parts becoming available, making the process easier and more accessible than ever before. Another reason for the swap could be for longevity. Perhaps you are looking to create a Grom that will last you for years to come, and the engine swap allows you to have a greater appreciation for the bike.

Think about it: more power means more fun, whether you're cruising around town, hitting the track, or just showing off your ride at a bike night. The increased performance can dramatically change the way you experience your Grom. It's not just about speed; it's about the feeling of exhilaration, the thrill of the ride. Plus, a new engine can give your Grom a whole new personality, transforming it from a fun little commuter into a serious performance machine. And the best part? It's a project that you can tackle in your own garage, with the right tools and a little bit of know-how. Engine swaps are a way to customize your Grom to perfectly fit your needs and riding style. It's a chance to build something truly unique, something that reflects your personality and passion for motorcycles.

Engine Swap Options for Your 2022 Grom

Alright, so you're sold on the idea. Now comes the fun part: choosing your new engine! The 2022 Honda Grom engine swap market offers a variety of options, each with its own pros and cons. The most common swaps involve engines from other Honda models, as well as some aftermarket options. The goal is to find an engine that fits within the Grom's frame and provides the power and performance you are looking for. You'll need to consider factors like the engine's size, weight, and mounting points, as well as the supporting modifications required. You will also have to consider your budget, skill level, and intended use for the bike. Here are a few popular choices:

Honda Engines

• Honda CRF150R Engine Swap: The CRF150R engine is a popular choice for Honda Grom engine swaps because it's a direct upgrade, offering a significant boost in power. This engine is a single-cylinder, four-stroke engine that's known for its reliability and performance. It's a great option for those looking for a relatively straightforward swap that provides a noticeable power increase. However, you'll likely need to modify the frame or use a specialized kit to get it to fit properly. The CRF150R engine offers a good balance of power and reliability, making it a versatile choice for various riding styles.
• Honda CBR250R Engine Swap: If you're looking for even more power, the CBR250R engine is a step up. This engine provides a significant increase in horsepower and torque, transforming your Grom into a mini-sportbike. You'll need to be prepared for a more complex swap, as the CBR250R engine is larger and heavier than the stock Grom engine. However, the result is a Grom that can hang with the big boys. With this swap, you will also need to consider modifications to your frame, as well as electrical and cooling system. This will require some extra effort but the extra power is going to be worth it!
• Honda XR100/CRF100 Engine Swap: While not as common as other options, the XR100/CRF100 engines can be a budget-friendly option. This swap is great for those who want a simple performance upgrade without breaking the bank. The XR100/CRF100 is known for its reliability and ease of maintenance, and the engine swap kits can be found online. The performance boost isn't as dramatic as with some of the larger engines, but it's still a noticeable improvement. While a slightly less dramatic increase in power compared to the other options, this is a great starter engine swap for those looking to begin their journey.

Aftermarket Engine Options

• Big Bore Kits: Big bore kits are not a complete engine swap, but rather a way to increase the displacement of your existing engine. This involves replacing the cylinder, piston, and sometimes the cylinder head with larger components. Big bore kits are a relatively easy and cost-effective way to boost your Grom's power without having to completely replace the engine. They can provide a significant increase in horsepower and torque, and many kits include other performance upgrades like a new camshaft and exhaust. This is a great starting point for beginners as it's not as complex, and you can always go for a complete swap later on.
• Engine Swap Kits: There are companies that sell complete Honda Grom engine swap kits that include everything you need to swap out your engine, including the engine itself, mounting hardware, and all the necessary parts. These kits are a convenient option for those who want a hassle-free swap. It's a good idea to consider your mechanical skills, budget, and desired performance gains before choosing an engine. Research the various options, read reviews, and watch videos to get a good understanding of what each swap entails.

What You Need to Consider Before You Start

Before you dive into a 2022 Honda Grom engine swap, there are a few things you need to consider. The best approach is to fully understand the project before you get your hands dirty. This will involve the process, from the cost and skill level required, to the potential impact on your Grom's performance and reliability. Skipping the planning phase can lead to costly mistakes and a lot of frustration.

Budget

First and foremost, you need to establish a budget. Grom engine swaps can range in price depending on the engine you choose, the parts you need, and whether you do the work yourself or have a shop do it. Factor in the cost of the engine, the swap kit (if you're using one), any supporting modifications like an upgraded exhaust or fuel management system, and any tools or equipment you might need. Don't forget to include the cost of fluids, such as oil and coolant. The total cost can quickly add up, so it's essential to set a realistic budget from the start. Remember that a budget will also help you narrow down your engine options and help you make informed decisions.

Skill Level

Next, assess your mechanical skills. Engine swaps are not for the faint of heart. If you're not comfortable working on engines, it might be a good idea to seek professional help. There are a lot of steps involved, from removing the old engine to installing the new one, and everything in between. You'll need to be able to understand wiring diagrams, work with hand tools, and have a good understanding of how engines work. If you're a beginner, it might be a good idea to start with a less complex swap or have a friend or professional guide you through the process.

Tools and Equipment

Make sure you have all the necessary tools and equipment before you start. You'll need a basic set of hand tools, including sockets, wrenches, screwdrivers, and pliers. You'll also need some specialized tools, such as a torque wrench, an engine stand, and possibly a lift. You might also need a welder, depending on the engine and swap kit. Having the right tools will make the process much easier and safer. Don't forget to gather all the necessary tools and equipment, so you don't have to stop mid-project to make a run to the hardware store.

Supporting Modifications

Consider what other modifications you might need to make to support the new engine. This can include an upgraded exhaust system, a fuel management system, a new air intake, and even a new cooling system. These modifications are often necessary to get the most out of your new engine and to ensure that it runs properly. Make sure you do your research and plan for any additional modifications you might need. These modifications will help you maximize the potential of your engine swap and ensure that your Grom runs smoothly and efficiently.

Legal Considerations

Before you start, check your local laws and regulations regarding engine swaps. Some jurisdictions have restrictions on engine swaps, especially if the new engine is significantly larger or modifies the emissions systems. Ensure you are familiar with your local laws. It's important to make sure that your 2022 Honda Grom engine swap is legal before you start. Make sure your motorcycle complies with all applicable regulations. This will save you time and money. Failing to comply can result in fines, and other issues. Ensure you are familiar with local laws to avoid any issues down the road.

The Engine Swap Process: A Step-by-Step Guide

Alright, you've done your research, chosen your engine, and you're ready to get started. Here's a general overview of the engine swap process. The steps will vary depending on the engine you choose and the specific kit you're using, but this will give you a good starting point. Engine swaps are a lot of fun, and the feeling of accomplishment once you're done is second to none.

Step 1: Preparation

• Gather all the necessary tools, parts, and equipment. Make sure you have everything you need before you start. You don't want to get stuck halfway through the process.
• Drain the oil and coolant from the old engine. This is a messy but necessary step.
• Disconnect the battery and remove any body panels or components that might be in the way. This includes the seat, fairings, and any other parts that might interfere with the swap.
• Take pictures of everything before you remove it, so you can remember how it all goes back together. This will be invaluable when you are reassembling your bike.

Step 2: Removing the Old Engine

• Disconnect all the wiring harnesses, fuel lines, and any other connections to the old engine. Be sure to label everything.
• Remove the exhaust system. This will make it easier to remove the engine.
• Unbolt the engine from the frame. It is recommended that you have a friend help you at this stage because it can be heavy.
• Carefully lift the old engine out of the frame. An engine stand can be useful here.

Step 3: Installing the New Engine

• Install the new engine into the frame. This may require some modifications to the frame or the use of an engine swap kit.
• Bolt the engine to the frame using the appropriate mounting hardware. Make sure everything is secure.
• Connect all the wiring harnesses, fuel lines, and any other connections to the new engine. Follow the wiring diagrams carefully.
• Install the exhaust system.

Step 4: Supporting Modifications

• Install any necessary supporting modifications, such as an upgraded exhaust, fuel management system, or air intake. This will help you get the most out of your new engine.
• Install the new cooling system if required. This is essential for preventing the engine from overheating.
• Install any necessary body panels or components that you removed in the first step.

Step 5: Final Steps

• Fill the engine with oil and coolant. Follow the manufacturer's recommendations.
• Check for leaks. Make sure there are no leaks before you start the engine.
• Start the engine and let it run for a while, checking for any issues. This is an exciting moment.
• Test ride your Grom and enjoy the new power! Take it easy at first and gradually increase the throttle as the engine breaks in.

Tips and Tricks for a Successful Grom Engine Swap

• Do your research: Before you start any project, thoroughly research your engine swap, and read the reviews. This will help you understand what's involved and avoid any surprises. There are tons of resources available online, including forums, YouTube videos, and articles. These resources are designed to help you, so use them.
• Use a high-quality kit: If you're using an engine swap kit, make sure it's from a reputable manufacturer. This will ensure that all the parts fit properly and that you have everything you need. Quality kits will save you time, money, and headaches.
• Take your time: Don't rush the process. Engine swaps can be time-consuming, so take your time and do the job right. Rushing can lead to mistakes. Rushing will result in frustration, and more money out of your pocket. Give yourself plenty of time.
• Label everything: As you remove parts, label them clearly. This will make reassembly much easier. You can use masking tape and a marker to label wires, hoses, and any other components. This will keep you organized and prevent any confusion.
• Take pictures: Take pictures of every step of the process. This will help you remember how everything goes back together, and it can be a lifesaver if you get stuck. Pictures can save the day. They will assist you with remembering how to put everything back together. They are essential to ensure you are putting everything back in the right position.
• Ask for help: Don't be afraid to ask for help from friends, online forums, or even a professional mechanic. There are plenty of people who are willing to share their knowledge and expertise. Asking for help is not a sign of weakness; it's a sign of wisdom.
• Test and tune: After the swap, test ride your Grom and make sure everything is working correctly. You might need to adjust the fuel management system or make other adjustments to optimize performance.
