So, you're thinking about transforming your Triumph Speed Twin 900 into a scrambler, huh? Awesome choice! The Speed Twin 900 is already a fantastic bike, blending classic style with modern performance, but giving it that scrambler edge opens up a whole new world of possibilities. Whether you're dreaming of tackling gravel roads, cruising through urban landscapes with a rugged vibe, or just want a bike that stands out from the crowd, this conversion can be a game-changer. This guide will walk you through everything you need to consider, from the initial planning stages to the final tweaks, ensuring you create a scrambler that perfectly matches your vision and riding style.

Planning Your Scrambler Build

Before you even touch a wrench, careful planning is crucial. This stage is all about defining your goals, setting a budget, and understanding the modifications involved. Proper planning will save you time, money, and potential headaches down the road. It's like laying the foundation for a house – a solid plan ensures a sturdy and successful build. Consider these essential aspects:

Defining Your Scrambler Style

What kind of scrambler are you envisioning? Is it a vintage-inspired machine with classic lines and retro tires, or a more modern take with aggressive styling and high-performance components? Maybe you're aiming for a practical adventure bike capable of tackling serious off-road terrain, or perhaps a stylish urban scrambler that looks just as good parked outside a coffee shop as it does tearing up a dirt trail.

  • Vintage Scrambler: Think classic Triumph scramblers of the 1960s. Key elements include a high-mounted exhaust, retro-style tires, a simple seat, and minimal instrumentation. The focus is on aesthetics and capturing the essence of the original scrambler era.
  • Modern Scrambler: This style blends classic scrambler elements with modern technology and design. Expect to see features like LED lighting, digital gauges, and more aggressive tires. The overall look is often more refined and performance-oriented.
  • Adventure Scrambler: Built for serious off-road adventures, this type of scrambler prioritizes functionality and durability. Key upgrades include long-travel suspension, skid plates, handguards, and luggage racks. The focus is on tackling challenging terrain and long-distance riding.
  • Urban Scrambler: This style emphasizes urban practicality and style. Look for features like comfortable seating, practical luggage options, and a balance between off-road capability and on-road performance. The goal is to create a bike that's both stylish and functional for city riding.

Setting a Realistic Budget

Scrambler conversions can range from relatively inexpensive to surprisingly costly, depending on the depth of the modifications and the quality of the parts you choose. It's essential to set a realistic budget early on to avoid overspending and ensure you can complete the project without cutting corners.

Start by listing all the modifications you want to make, then research the cost of each component. Don't forget to factor in the cost of labor if you're not doing the work yourself, as well as any potential unforeseen expenses.

  • Parts: Research the prices of tires, exhaust systems, seats, handlebars, lighting, and other components.
  • Labor: Get quotes from local shops for any work you're not comfortable doing yourself.
  • Unexpected Costs: Set aside a contingency fund for unexpected expenses, such as damaged parts or additional modifications.

Understanding the Modifications

Familiarize yourself with the various modifications involved in a scrambler conversion. This will help you make informed decisions about which modifications are right for you and ensure you have the skills and tools necessary to complete the project. Research each modification thoroughly, watch tutorial videos, and read online forums to learn from other builders' experiences. Understanding the complexities of each modification will help you avoid common mistakes and ensure a successful build.

  • Exhaust System: High-mounted exhausts are a signature scrambler feature, but they can also be one of the most expensive and complex modifications. Research different exhaust options, consider the impact on performance and sound, and ensure the exhaust is compatible with your bike.
  • Tires: Swapping the stock tires for knobby off-road tires is a must for any serious scrambler conversion. Research different tire options, consider the type of terrain you'll be riding on, and ensure the tires are the correct size for your wheels.
  • Suspension: Upgrading the suspension can significantly improve off-road performance and handling. Research different suspension options, consider your riding style and the type of terrain you'll be riding on, and ensure the suspension is compatible with your bike.

Key Modifications for Your Speed Twin 900 Scrambler

Now, let's dive into the specific modifications that will transform your Speed Twin 900 into a scrambler. These modifications cover everything from aesthetics to performance, ensuring your bike looks the part and performs flawlessly on any terrain.

High-Mounted Exhaust System

A high-mounted exhaust system is perhaps the most defining feature of a scrambler. Not only does it give the bike that classic scrambler look, but it also improves ground clearance and protects the exhaust from damage when riding off-road. Several aftermarket options are available for the Speed Twin 900, ranging from full systems to slip-on mufflers.

When choosing an exhaust system, consider the following factors:

  • Sound: Do you want a loud and aggressive exhaust note, or something more subtle and refined?
  • Performance: Will the exhaust system improve horsepower and torque, or is it primarily for aesthetics?
  • Price: Exhaust systems can range from a few hundred dollars to several thousand, so set a budget and stick to it.
  • Installation: Are you comfortable installing the exhaust yourself, or will you need to take it to a professional?

Knobby Tires

Swapping the stock tires for knobby off-road tires is essential for improving traction and handling on loose surfaces. Look for tires with an aggressive tread pattern and a durable construction. Several brands offer tires specifically designed for scrambler conversions, so do your research and choose a set that's right for your riding style and the type of terrain you'll be tackling.

Consider these tire characteristics:

  • Tread Pattern: An aggressive tread pattern will provide better traction on loose surfaces, while a smoother tread pattern will offer better on-road performance.
  • Size: Ensure the tires are the correct size for your wheels and that they won't rub against the swingarm or fender.
  • Durability: Choose tires with a durable construction that can withstand the rigors of off-road riding.

Upgraded Suspension

While the Speed Twin 900's stock suspension is decent for street riding, it's not ideal for off-road use. Upgrading the suspension with longer travel forks and shocks will improve handling and comfort on rough terrain. Several aftermarket options are available, ranging from basic spring and damper upgrades to full cartridge kits.

When choosing suspension upgrades, consider the following:

  • Travel: Longer travel suspension will provide better off-road performance, but it can also raise the bike's ride height and make it more difficult to handle on the street.
  • Adjustability: Adjustable suspension allows you to fine-tune the ride to your preferences and the type of terrain you're riding on.
  • Quality: Invest in high-quality suspension components from a reputable brand to ensure they'll last and perform well.

Scrambler Seat

A flat, minimalist seat is another defining feature of a scrambler. It not only looks the part, but it also provides more freedom of movement when riding off-road. Several aftermarket options are available for the Speed Twin 900, ranging from simple flat seats to more sculpted and comfortable designs.

Think about these seat features:

  • Comfort: Choose a seat that's comfortable for long rides, especially if you plan on using your scrambler for touring.
  • Style: Select a seat that matches the overall aesthetic of your scrambler build.
  • Fit: Ensure the seat fits properly on your bike and doesn't interfere with any other components.

Minimalist Lighting

To complete the scrambler look, consider swapping the stock lighting for smaller, more minimalist units. LED headlights, taillights, and turn signals are a popular choice, as they're brighter, more energy-efficient, and more durable than traditional incandescent bulbs. This can seriously change the look of your bike. There are many designs out there, pick what will fit your needs.

Additional Modifications and Considerations

Beyond the core modifications, several other upgrades can enhance your Speed Twin 900 scrambler. These modifications can improve performance, comfort, and aesthetics, allowing you to create a truly unique and personalized machine.

Handlebars and Controls

Swapping the stock handlebars for wider, flatter bars can improve control and comfort when riding off-road. Consider adding bar risers to raise the handlebars and further improve ergonomics. Upgrading the grips and levers can also enhance comfort and control.

Skid Plate

A skid plate is essential for protecting the engine and exhaust from damage when riding off-road. Look for a skid plate that's made from durable materials and provides adequate coverage. Some skid plates also include integrated engine guards for added protection.

Handguards

Handguards protect your hands from the elements and prevent damage to the levers in the event of a fall. Look for handguards that are easy to install and provide adequate coverage. Some handguards also include integrated turn signals for added functionality.

Luggage Options

If you plan on using your scrambler for touring or adventure riding, consider adding luggage options such as panniers or a top box. Several aftermarket options are available, ranging from soft bags to hard cases. Choose luggage options that are durable, waterproof, and easy to install.

Custom Paint and Graphics

Finally, consider adding custom paint and graphics to personalize your Speed Twin 900 scrambler. This is a great way to make your bike stand out from the crowd and reflect your unique style. Work with a professional painter to create a design that's both eye-catching and durable.

Conclusion

Converting your Triumph Speed Twin 900 into a scrambler is a rewarding project that can transform your bike into a unique and capable machine. By carefully planning your build, choosing the right modifications, and paying attention to detail, you can create a scrambler that perfectly matches your vision and riding style. So, get wrenching and enjoy the ride!
