Cafe Racer Honda CB750: Build, Mods, And History

The Honda CB750 is a motorcycle that is synonymous with the cafe racer culture. This iconic bike, first introduced in 1969, revolutionized the motorcycle industry and quickly became a favorite among custom builders and enthusiasts. In this guide, we'll dive deep into the world of cafe racer Honda CB750s, exploring their history, modifications, and the process of building your own.

What is a Cafe Racer?

Before diving into the specifics of the CB750, it's important to understand what a cafe racer actually is. The cafe racer culture originated in 1960s England, where motorcycle enthusiasts modified their bikes to resemble the sleek, minimalist machines used in Grand Prix racing. These bikes were built for speed and handling, designed for quick dashes between cafes – hence the name.

Key characteristics of a cafe racer include:

• Stripped-down design: Minimal bodywork, removing any unnecessary parts.
• Low handlebars: Clip-ons or clubman bars for an aggressive riding position.
• Rear-set footpegs: Positioning the rider further back for better control.
• Single seat: Emphasizing the solo riding experience.
• Fuel tank: Often a classic, streamlined design.

It was the first mass-produced motorcycle with an inline-four-cylinder engine and a front disc brake, setting a new standard for performance and reliability. Its robust engine and readily available parts made it an ideal platform for customization, quickly becoming a favorite for cafe racer conversions.

Why the CB750 is Perfect for Cafe Racers:

• Engine: The 750cc inline-four engine is powerful and reliable, providing ample performance for a cafe racer.
• Availability: CB750s are readily available and relatively affordable, making them accessible to a wide range of builders.

Building Your Own Cafe Racer Honda CB750

Building a cafe racer is a rewarding but challenging project. It requires a combination of mechanical skills, design sense, and patience. Here's a step-by-step guide to the process:

1. Finding a Donor Bike

The first step is to find a suitable CB750 to use as a donor bike. Look for a bike that is in relatively good mechanical condition, as this will save you time and money in the long run. Common CB750 models used for cafe racer builds include the K models (K0-K8) from the 1969-1978 era. Websites like Cycle Trader and eBay are good places to start your search.

2. Planning Your Build

Before you start wrenching, take the time to plan your build. This includes:

• Design: Sketch out your vision for the bike. Consider the overall look, color scheme, and specific modifications you want to make.
• Budget: Set a realistic budget for the project. Cafe racer builds can range from a few thousand dollars to significantly more, depending on the level of customization.
• Timeline: Estimate how long the build will take. Be realistic, as these projects often take longer than anticipated.

3. Stripping the Bike

Once you have a plan, it's time to strip the bike down to its bare frame. This involves removing all the bodywork, seat, fuel tank, and other unnecessary parts. This process will give you a clear view of the bike's core components and allow you to identify any issues that need to be addressed.

4. Frame Modifications

Many cafe racer builds involve modifications to the frame. This can include:

• Removing unnecessary tabs and brackets: Cleaning up the frame for a cleaner look.
• Hoop modification: Adding a rear hoop to support the seat and create a classic cafe racer profile.
• Bracing: Adding bracing to the frame for increased rigidity and handling.

5. Engine Rebuild and Upgrades

The CB750 engine is robust, but it's a good idea to rebuild it during a cafe racer build. This ensures that the engine is in top condition and allows you to address any wear and tear. Common engine upgrades include:

• High-compression pistons: Increasing power and torque.
• Performance camshafts: Optimizing valve timing for better performance.
• Carburetor upgrades: Installing Mikuni or Keihin carburetors for improved fuel delivery.
• Electronic ignition: Replacing the points ignition system with a more reliable electronic system.

6. Suspension Upgrades

Upgrading the suspension is crucial for improving the handling of your cafe racer. Common upgrades include:

• Fork modifications: Installing stiffer springs and emulators in the front forks.
• Rear shocks: Replacing the stock shocks with high-performance aftermarket units.
• Steering damper: Adding a steering damper to reduce wobble and improve stability.

7. Brakes

Stopping power is just as important as performance. Upgrading the brakes is essential for a safe and enjoyable ride. Common brake upgrades include: — South Alabama Vs. Louisiana-Monroe: A Deep Dive

• Stainless steel brake lines: Providing a firmer brake feel.
• Brake pads: Upgrading to performance brake pads for increased stopping power.

8. Wheels and Tires

The wheels and tires play a significant role in the look and handling of your cafe racer. Common upgrades include:

• Aluminum rims: Lighter and stronger than the stock steel rims.
• Tires: Selecting tires that match your riding style and the look you're going for. Common choices include Avon Roadrider and Bridgestone Battlax.

9. Bodywork and Styling

The bodywork is what gives your cafe racer its distinctive look. Common modifications include:

• Fuel tank: Replacing the stock fuel tank with a classic cafe racer tank, such as a Manx or a Bates style tank.
• Seat: Installing a solo seat, often with a rear cowl.
• Fairings: Adding a front fairing, such as a Dunstall or a Rickman fairing.
• Rearsets: Installing rear-set footpegs for an aggressive riding position.
• Clip-ons or clubman bars: Replacing the stock handlebars with low-profile clip-ons or clubman bars.

10. Electrical System

The electrical system is often overlooked in cafe racer builds, but it's crucial for reliability. Consider:

• Wiring harness: Replacing the old wiring harness with a new one.
• Battery: Using a lightweight lithium-ion battery.
• Charging system: Upgrading the charging system if necessary.
• Lighting: Installing minimalist lighting, such as LED taillights and turn signals.

11. Exhaust System

The exhaust system is not only functional but also a key styling element. Common upgrades include:

• 4-into-1 exhaust: Providing better performance and a classic cafe racer look.
• Muffler: Selecting a muffler that matches your desired sound level and style.

The final touches are what make your cafe racer truly unique. This includes:

• Paint: Choosing a paint scheme that reflects your personal style.
• Polishing: Polishing the engine cases and other components for a clean look.
• Details: Adding small details, such as bar-end mirrors and custom grips, to complete the look.
