FZ-07 Stunt Build Guide: Essential Mods & Recommendations

Hey guys! So, you're looking to turn your FZ-07 into a stunt machine? Awesome! The FZ-07 (now MT-07) is a fantastic bike for stunting – it's lightweight, torquey, and super agile. But transforming it into a reliable stunt bike requires some key modifications. Let's dive into the must-have upgrades and recommendations to help you build the ultimate FZ-07 stunt rig.

1. Essential Crash Protection

When it comes to stunting, crashing is part of the learning curve, so crash protection is absolutely paramount. This isn't just about saving your bike; it's about preventing serious damage that could sideline you for weeks. Think of crash protection as an investment in your stunting future – it'll pay for itself in saved repairs and downtime. So, where do you start with crash protection for your FZ-07 stunt build? The bare minimum should include a sturdy cage, axle sliders, and handguards. Let's break these down:

1.1 Stunt Cage

The stunt cage is arguably the most crucial piece of protection. It's a structural framework that wraps around the engine and frame, absorbing impact during drops and crashes. A good cage will protect vital components like the engine casings, frame, and coolant reservoir. There are a ton of options out there, but look for a cage made from high-strength steel tubing with multiple mounting points for maximum rigidity. You want something that can withstand repeated hits without bending or breaking. Installation can be a bit involved, often requiring the removal of fairings and some careful bolting, but it's a job you can definitely tackle in your garage with the right tools. Don't skimp on the cage – this is your bike's first line of defense.

1.2 Axle Sliders

Next up are axle sliders. These little guys mount to the axles on your front and rear wheels and are designed to take the brunt of a slide. They prevent the wheels, forks, and swingarm from grinding directly on the pavement, which can save you from costly repairs. Axle sliders are relatively inexpensive and super easy to install – usually just a matter of unscrewing the axle nut, sliding the slider in place, and re-torquing the nut. There are different styles available, some with a simple mushroom-shaped slider and others with a more elaborate cage design. Choose a style that fits your aesthetic preference, but make sure they're made from a durable material like delrin or aluminum.

1.3 Handguards

Don't forget about your hands! Handguards protect your levers and, more importantly, your hands and fingers in the event of a spill. Broken levers can stop a session in its tracks, and injured hands can keep you off the bike for even longer. There are two main types of handguards: full-wrap and flag-style. Full-wrap handguards offer the most protection, as they have a metal backbone that attaches to both the handlebar and the bar end. Flag-style handguards are more minimalist and offer less protection, but they can still deflect debris and prevent lever damage. For stunting, full-wrap handguards are the way to go. They provide a solid barrier against impacts and can even help prevent the handlebars from bending in a crash.

Choosing the right crash protection is like picking the right armor for battle. It needs to be strong, reliable, and able to take a beating. Don't cheap out on this – your bike (and your body) will thank you for it!

2. Gearing and Control Modifications

The stock gearing on the FZ-07 is fine for street riding, but for stunting, you'll want to make some changes to improve low-speed control and wheelie performance. The goal here is to get the bike into the powerband quicker and make it easier to loft the front wheel. We're also going to look at modifications that enhance your control over the bike, giving you the confidence you need to push your limits. Let's break down the key gearing and control mods for an FZ-07 stunt build.

2.1 Gearing Changes

The most common gearing modification for stunting is to increase the size of the rear sprocket. This effectively lowers the overall gear ratio, giving you more torque at the rear wheel. A larger rear sprocket will make it easier to clutch up wheelies and maintain control at low speeds. The general rule of thumb is to go up 6-10 teeth on the rear sprocket. For example, if your stock rear sprocket is a 43-tooth, you might try a 49-tooth or 53-tooth sprocket. This might sound like a big change, but it makes a world of difference in stunting performance. When you're choosing a new sprocket, make sure it's made from a durable material like steel or aluminum. Steel sprockets are heavier but more resistant to wear, while aluminum sprockets are lighter but may need to be replaced more often. You'll also need to adjust your chain length to accommodate the larger sprocket. It's a good idea to replace your chain and sprockets as a set to ensure proper wear and performance.

2.2 Handbrake

A handbrake is an essential modification for advanced stunting maneuvers like rolling stoppies and drifts. It allows you to independently control the rear brake with your hand, freeing up your foot for other inputs. There are several ways to install a handbrake on an FZ-07. Some kits replace the stock rear master cylinder with a dual-caliper setup, while others add a second caliper to the rear rotor. Dual-caliper systems are generally preferred for their superior braking power and modulation. Installing a handbrake can be a bit more complex than other modifications, as it involves hydraulic lines and bleeding the brakes. If you're not comfortable working with hydraulic systems, it's best to have a professional install it. But trust me, once you get used to a handbrake, you'll wonder how you ever stunted without one. It opens up a whole new world of possibilities.

2.3 12 O'Clock Bar

A 12 o'clock bar is a steel bar that extends upwards from the rear subframe, providing a contact point for when you're riding wheelies at the 12 o'clock position (fully vertical). It prevents the bike from looping out and protects the tail section in case of a crash. A good 12 o'clock bar will be made from thick-walled steel tubing and securely mounted to the subframe. Some bars also incorporate a scrape plate, which is a replaceable metal plate that takes the brunt of the wear when you're dragging the bar. Installing a 12 o'clock bar usually requires some modification to the rear fairings, and you may need to drill holes in the subframe. But it's a worthwhile investment if you plan on pushing your wheelies to the limit. Not only does it protect your bike, but it also gives you a sense of confidence knowing you have a safety net.

2.4 Seat Modifications

Seat modifications might seem like a minor detail, but they can significantly impact your comfort and control while stunting. A grippier seat cover will prevent you from sliding around on the seat, giving you more stability and control. You can either purchase a pre-made gripper seat cover or have your stock seat reupholstered with a gripper material. Some stunt riders also prefer to modify the shape of the seat, making it flatter or adding a step to lock them in place during wheelies. This is a matter of personal preference, so experiment with different options to see what works best for you. A comfortable and secure seat will allow you to focus on your riding without worrying about slipping and sliding.

3. Suspension Upgrades

The stock suspension on the FZ-07 is adequate for street riding, but it's not ideal for the demands of stunting. Stunt riding puts a lot of stress on the suspension, and the stock components can quickly become overwhelmed. Upgrading your suspension will improve your bike's handling, stability, and overall performance. It'll also make your bike more predictable and easier to control, which is crucial when you're pushing your limits. Let's take a look at the key suspension upgrades for an FZ-07 stunt build.

3.1 Fork Upgrades

The front forks are the most critical area to upgrade for stunting. The stock forks are soft and lack adjustability, which can lead to a mushy and unpredictable front end. There are several options for upgrading your forks, ranging from simple modifications to complete replacements. The most common upgrade is to install stiffer fork springs and heavier fork oil. This will improve the fork's resistance to bottoming out and provide a more stable feel. You can also install cartridge emulators, which replace the stock damper rods with adjustable cartridges. Cartridge emulators offer improved damping performance and allow you to fine-tune the fork's behavior. For the ultimate in performance, you can replace the entire fork with cartridge forks from a higher-spec bike, such as a Yamaha R6. This is the most expensive option, but it offers the best possible performance and adjustability. No matter which option you choose, upgrading your forks will make a huge difference in your bike's handling and control.

3.2 Rear Shock

The rear shock also plays a crucial role in your bike's handling. The stock shock is similar to the forks – it's soft and lacks adjustability. Upgrading the rear shock will improve your bike's stability and prevent it from wallowing during wheelies and stoppies. There are several aftermarket shocks available for the FZ-07, ranging from basic replacements to fully adjustable units. A basic replacement shock will offer improved damping performance over the stock unit, while an adjustable shock will allow you to fine-tune the ride height, compression, and rebound damping. A fully adjustable shock is the best option for stunting, as it allows you to dial in the suspension to your specific riding style and preferences. When choosing a rear shock, look for one with a remote reservoir, which helps to dissipate heat and maintain consistent damping performance.

4. Other Important Mods

Beyond the essential crash protection, gearing, control modifications, and suspension upgrades, there are a few other mods that can enhance your FZ-07 stunt build. These mods aren't strictly necessary, but they can make your bike more comfortable, reliable, and perform better overall. Let's take a look at some of these additional mods.

4.1 Radiator Guard

A radiator guard is a simple but effective way to protect your radiator from damage. Stunt riding often involves close proximity to other bikes and the ground, and the radiator is vulnerable to rocks, debris, and impacts. A punctured radiator can lead to overheating and engine damage, so a radiator guard is a worthwhile investment. They're relatively inexpensive and easy to install, typically bolting directly to the radiator mounts. Choose a radiator guard made from durable materials like aluminum or stainless steel for maximum protection.

4.2 Steel Braided Brake Lines

Steel braided brake lines are a popular upgrade for any motorcycle, and they're especially beneficial for stunting. Steel braided lines replace the stock rubber brake lines, which can expand under pressure, leading to a spongy brake feel. Steel braided lines don't expand, providing a firmer and more consistent brake feel. This is crucial for precise braking during stoppies and other maneuvers. They're also more resistant to wear and tear than rubber lines, making them a durable upgrade. Installing steel braided brake lines is a relatively straightforward process, but you'll need to bleed the brakes afterwards to remove any air from the system.

4.3 Upgraded Clutch

The clutch takes a beating during stunting, especially if you're doing a lot of clutch-up wheelies. The stock clutch can wear out quickly under these conditions, leading to slipping and poor performance. Upgrading to a heavy-duty clutch with stronger springs and friction plates will improve your clutch's durability and performance. There are several aftermarket clutch kits available for the FZ-07, ranging from simple spring upgrades to complete clutch replacements. A stronger clutch will give you more consistent engagement and prevent slippage, allowing you to launch wheelies with confidence. If you're serious about stunting, an upgraded clutch is a must-have.

4.4 Pegs

Some stunt riders choose to install modified pegs for better grip, and more secure footing.

Conclusion

Building an FZ-07 stunt bike is a rewarding project. By focusing on crash protection, gearing and control, suspension, and other key modifications, you can transform your FZ-07 into a wheelie machine. Remember, safety first! Always wear proper gear and practice in a safe environment. With the right setup and some practice, you'll be stunting like a pro in no time. Good luck, and have fun!
