Inspiring Honda CB77 Cafe Racer Builds You Should See
The Honda CB77 has inspired many builders to create unique cafe racers. These projects showcase the bike’s potential for customization.
Mid Life Cycles Build
Mid Life Cycles, based in Australia, crafted a CB77 cafe racer that blends 1960s style with modern touches. They retained the original fuel tank and added a fiberglass seat resembling the Ducati 750SS. The bike features Tingate clip-ons, Brooks leather grips, and Tomaselli rearsets. A rare Aprilia headlight from the early 1960s and Borrani alloy wheels complete the vintage look. The exhaust pipes were ceramic-coated in black for durability and style. This build won the Just Bikes Build Off in 2012.
Oni Motorworks Build
Len Higa of Oni Motorworks in California transformed a 1961 Honda CB77 into a cafe racer with handcrafted aluminum bodywork. He designed the fuel tank and seat from aluminum sheets, giving the bike a sleek appearance. The build includes Magura clip-on handlebars, Avon Roadrunner tires, and a CB160 headlight bucket modified to fit CB77 gauges. The engine was upgraded with high-performance cams and 27mm Keihin carburetors. This motorcycle won the Best Original Award at the Born Free 2 Show.
Pipeburn Feature
Hill Hudson, an illustrator from Portland, Oregon, built a CB77 cafe racer after discovering the bike had been unused for decades. He rebuilt the engine, adjusting the gear ratios for better acceleration. The frame was stripped of unnecessary parts and repainted. Hudson kept the tank, fenders, and seat in raw steel for an industrial look. He crafted the seat hump from an extra CB77 tank and had it upholstered by New Church Moto. This project highlights the creativity possible with a CB77 base.
What Are the Best Modifications for a Honda CB77 Cafe Racer?
Performance Upgrades
Upgrading the engine improves both speed and ride quality. Many builders install high-compression pistons to increase power. Larger carburetors also help the engine breathe better. A free-flowing exhaust system improves throttle response. These changes allow the Honda CB77 to perform closer to modern bikes. They also make the ride more engaging on short city rides and open roads.
Aesthetic and Functional Enhancements
Clip-on handlebars are a common upgrade. They lower the rider’s position for a sportier feel. Rearsets replace the original foot controls. These parts give better ground clearance and help with cornering. Builders often choose a single-seat unit to follow the cafe racer look. Custom seat pans, either fiberglass or aluminum, reduce weight and improve design.
Lighting also plays a role in both safety and style. Swapping out bulky factory lights for LED headlamps and tail lights gives a cleaner finish. Builders also add bar-end indicators or hidden turn signals to keep the design minimal.
Electrical and Instrumentation
Many Honda CB77s come with old or worn wiring. Replacing the wiring harness increases reliability. Some builds include modern ignition systems. These systems provide faster starts and better fuel use. Lightweight lithium-ion batteries help reduce bulk under the seat.
Digital gauges are also becoming common. Builders install compact speedometers or combo meters with basic functions. These tools help track performance without cluttering the handlebar area. Overall, the goal is to blend modern function with vintage form. Each upgrade adds purpose and improves the riding experience.
Common Problems Builders Face with the CB77 Cafe Racer
Finding Original or Fit-Compatible Parts
The Honda CB77 was produced in the 1960s. Many of its original parts are now hard to find. Components like side covers, exhaust systems, and switchgear often require long searches. Some builders buy second-hand parts from online marketplaces or swap meets. Others use reproduction parts that match the size and fit of the originals. Even so, not all replacement parts work perfectly, and adjustments are sometimes needed.
Restoring the Engine and Drivetrain
Most CB77 engines are over 50 years old. Wear and age affect performance and reliability. Builders often face problems like worn pistons, leaky gaskets, and noisy gearboxes. Fixing these issues requires patience and basic mechanical knowledge. Some owners rebuild the engines fully using new seals, rings, and bearings. Access to technical manuals helps during this process. In many cases, tuning the carburetors and adjusting the timing also improves performance.
Upgrading the Electrical System
The stock electrical system on the CB77 is outdated. Old wires can crack or short. The charging system may not support modern accessories like LED lighting. Upgrading the system with new wiring, a modern rectifier, and a better battery is a common step. But this can be difficult for beginners. Some builds also require changing the ignition type to improve start-up and stability. Careful planning and clear wiring diagrams are needed to avoid future problems.
Balancing Style and Function
Every builder wants a clean and stylish finish. But removing too many parts can reduce safety and comfort. Some changes make maintenance harder. For example, hiding the battery or electrical units may look better but can limit access. Builders must balance visual design with rider comfort and long-term use. Proper planning helps avoid mistakes. Measuring the space before cutting or welding any part saves time and prevents frame damage.
Budget and Time Management
Building a cafe racer takes both time and money. A clean base bike can cost more at the start but saves money later. In contrast, cheaper bikes may need full restoration. Each part, tool, and modification adds to the cost. Time also adds up. Even a simple build can take several months to complete. Builders must stay organized, plan each stage, and avoid rushing. Careful steps lead to better results and fewer regrets later.
Resources and Communities
Online Forums and Communities
Several online forums support builders working on the Honda CB77. These platforms provide helpful advice, shared experiences, and detailed guides. Honda Twins Forum is a trusted space where members discuss restoration tips, engine repairs, and wiring upgrades. Do The Ton focuses more on custom cafe racer projects. It includes build logs, part reviews, and problem-solving threads. Both forums have active users who give honest, practical support.
Parts Suppliers and Shops
Finding the right parts is key to a smooth build. Many builders turn to trusted vintage suppliers. Common Motor Collective offers parts for older Honda models, including engine kits and electrical upgrades. 4into1.com stocks a wide range of replacement parts and accessories. For rare items, eBay and motorcycle swap meets are useful. Some custom shops also create handcrafted parts like seats, brackets, and tanks tailored for the Honda CB77.
Video Tutorials and Technical Guides
Watching the process helps builders understand each step. YouTube channels like Hugh’s HandBuilt and Classic Octane show detailed builds from start to finish. These videos explain tools, installation steps, and common issues. Technical manuals and original service books are also important. They give clear specifications, torque settings, and wiring diagrams. Builders can often find digital copies online or buy print versions from parts suppliers.
Local Motorcycle Clubs and Events
Offline support is also helpful. Local vintage motorcycle clubs often include CB77 owners. These clubs organize group rides, tech days, and meet-ups. Some events feature bike shows where builders can display their work. Talking in person with other builders allows the sharing of advice, tools, and inspiration. Clubs also help riders stay connected with the broader vintage motorcycle scene.
