Dino Maltoni of Mendoza, Argentina sent us this build of a Kawasaki Zephyr 550. Below he tells us in his own words about the build.
Basically it had to cut and to manufacture a subchasis to measure since originally it brings a base of chassis type delta, to be able to give a more retro aspect and at the same time to obtain lines more according to a racer cafe. Glass of artisan way conservando a.aspecto similar to the one that brings of factory but of minor dimensions. To the same one was introduced to him a double light back light. In the front we adapted a copulino somewhat modified, was placed semimanillares, the whole painting was painted with powder paint as it came from the factory. Was made tailor made escapes and stainless steel. The pinto with a combination of green trikes and a kawasaki engine was given a glossy black color. The upholstery is also handmade which combines different textures and threads.

Marc Roissette sent us a time lapse video of the entire build. Below is a story behind the build, in his own words.
I bought this GSX 750 last year as the other owner had some issues with it not running well and also a fuel float / leak flooding the cylinders. I was able to negotiate a fairly good deal on the bike and this is where the project started. After picking up the bike and getting it home, I decided the first step was to sort out the carbies and get the bike running to have a sense of things I needed to change before going into the modification side. After a strip down and re-build of the carbs I found the last person to build͟d had left some parts out causing 1 of the two issues.
Watch his time lapse video to see the entire process.
The second problem to solve before getting it running right was tank pet cock not closing when shut off causing constant fuel drain into the engine. I installed an inline fuel tap to solve this issue in the short term. Taking it down to a track day in stock form and cutting a few laps I decided the whole front end needed replacing as the front suspension was like a trampoline and the brakes were wooden and just did not stop in the way I wanted, the rear sets were rubber and had no feel and the exhaust did not have the note or look I wanted, it was also time to re-jet the carbs and get some nice K&N filters. The bike went home and was stripped back to just the frame, engine out, carbs off and front end off to the shelf. The frame was then taken to with a grinder to remove all the old and un-used tabs to clean up the look of the bike, a new rear hoop welded onto improve rigidity and sent off to be powder coated. After searching around for a GSXR front end locally I was unable to get the parts required which would have made for a nice easy front end bearing conversion. I was though lucky enough to get a Ducati 996 front end off a good friend at Vendetta Racing which then needed some more work to the frame to get it attached due to the 35mm head stem.
Whilst all this work was going on a tail piece was ordered from Norway and I manufactured seat pan and tail plate to store all the wiring, battery etc and have a seat pad made up. Once completed the tank and tail piece were sent off for paint in a scheme I had designed in photoshop.More parts were ordered for the bike such as new chain, sprockets, rears sets, levers, gauge cluster, filters, short throttle and others to get the look and feel I wanted for the bike.
The wiring harness was stripped back to bare and re-run causing some minor headaches as finding a workshop manual for a GSXF 750 was near impossible! Once the freshly powder coated frame was back the install of parts could start once again. First the engine was re-installed after a good degrease and clean then the wiring harness fed through the bike before the rear swing arm was re-attached. Getting the new front end on the bike was difficult without the required hoist to lift the bike up but I was able to use a step ladder and some bike tie downs to get the job done. With front end on the bike was stable and rest of the work for re-assembly could be completed. Once the wiring harness was all re-connected to controls it was time to balance the carbs. Now this is tricky, being my first time working with in line carbs I was a little clueless as to how to go about the task, after much time spent looking through a manual for a Bandit 600 and youtube videos I got the basics sorted out and balancing tool on the carbs to complete the job. After about 3 hours of work on and off the balance and pilots were adjusted a level that worked and the rest of the parts could be installed!
Spencer Ashburn wrote to us about a project that he and his dad started together. The two watched all our Cafe Racer TV videos and from that experience they were inspired to start building café racers.
“We loved the idea of taking everything off the bike and making it go as fast as it could for starters, but then to add to the style of the bike to make it our own design. To go along with that we made the bike with whatever we had laying around the shop. We embodied this idea about two years ago,” said Spencer.
What started out as a father and son bike build turned into a father and son bike collection.
“We both found that we enjoyed working on bikes and creating our own design but we also loved working together and adding to each others ideas and visions. We loved it so much that we ended up having Friday bike nights, where we would spend the remainder of Friday evenings working on the bikes and grilling out. My dad, Troy, started as a mechanic and is now a painter. So we do have some tools to work with, but we don’t have this big elaborate shop with all the tools in the world.
We made this bike with a couple of hammers, a torch, a welder, and some hair brained idea that we could make a bike of our own. Although this bike isn’t completely finished. It still needs to be pulled apart and properly cleaned and painted,” said Spencer.
That didn’t stop the two from showing it off at the Slimmey Crud Run in Wisconsin, where it drew a lot of attention. Net, they took it to Rockerbox in Wisconsin and put it in the show, and successfully cameg away with a win.
“This bike may not be the simple café racer that you may very well know, but the café racer isn’t just about the bike itself, it’s the history behind the bike in how you made it your own. It’s how you took the bike and made it faster and better then the next guy. And if you were to ask me, I think this bike embodies that to the fullest”, Spencer told us.

This build comes to us from Loen Montefusco from Stockholm. Below is his story of the build in his own words.
I kept the stock tank and just did the dents on it. I shortened the rear end of the frame to add the loop and gave it an angle. I removed the engine and changed some gaskets on it, then washed it of course. The top clamp was a major league job but was very fun to do. I removed the risers and drilled a big hole for the stock fuel gauge and it wasn’t easy.
The springs on the fork are cut down to lower the whole bike. The rear shocks and harley as well as the pipes. The stock pipes of the Suzuki are just out of proportion, way too big for the Cafe Racer. I bought the seat but modified it a lot to get the shape I wanted, short and low but still comfortable. The front fender is stock but shortened and modified to get the brackets close to the tire. The back fender is from an old Swedish Husqvarna Rödmyra from 42′. The speedos are the smallest possible for the cafe. The headlight is stock. It’s just upside down to get it as close as possible to the frame. Avon tires are the biggest possible for the rims.
The whole build took three months.
This build comes to us from Bernie Blackwell in Melbourne, Australia. He tells you about it in his own words.
This 1973 Honda 750.4 cylinder completed its early life in the early 1980’s racing at weekends as a Hillclimber in country Victoria. Rumour has its name as the Bucking Bronco! Discovered in a Leongatha farmshed in early 2011,she was resurrected over 3 1/2 years. The battered original was stripped of 11kg of extraneous parts and fittings….with an industrial angle grinder!
The desired build was to achieve a Manx Nortonlike look(circa 1960)…. organic, brutal, muscular and yet elegant….with a minimal bare hungry look.
The handmade fuel tank,oil tank and tailpiece were fabricated by Bernie Willett of Eltham. Every nut, bolt, washer and bracket has been replaced or fabricated by hand.and its all been mastered by Greg Cook of Leongatha.
Some 40 years after its appearance at the World Exhibition in Tokyo (note the Souvenir coin on the tailpiece) this once mass produced modern classic has been given a full stripped down makeover.
Bucking Bronco lives on!…as CB73.
This story comes to us from our friends at Atlanta Motorcycle Works. The team recently completed a build for a loyal customer who lost his father in the middle of a restoration project. This is the story in their own words.
Jared Morris ins’t your average “motorcycle guy.” Jared gets extremely passionate and involved in what he’s riding, this is especially the case with his father’s Yamaha RD400. The project with his father became a “ride as you work” type project. We could often hear Jared tearing down the street of his nearby neighborhood. While working on the project Jared’s dad fell ill, leaving him unable to assist Jared with the project. As life became more hectic for Jared, the bike became hard to make time for. Jared had been a long time friend and customer of Atlanta Motorcycle Works. We had helped Jared with small stuff all over his bike, but this time he had a different request. Jared wanted a completely custom motorcycle to honor his father who recently passed. From that point on we gave this bike everything we had in order to deliver something amazing to our friend.
Jared and his family were blown away with the end result. There’s a long list of things that set this bike apart from a stock RD400, but the most notable things would be the RD400 Daytona fork swap as well RZ350 swing arm swap and wheels. There’s a custom bracket allowing for an RZ Brembo front caliper. The Carbs have been vapor honed and re-jetted to work with the new DG exhaust and pod filters. The motor has been vapor honed, and the case covers have been powder coated. A new halo headlight has been fitted with new brackets. Updated hand controls were added with a pair of blast from the past rear sets to match. The front fender is an item off an XS750 that has been modified to fit this bike. The paint work was done with what Jared’s dad had planned for the bike. Jared’s Dad, Bob, was a flat track racer in his younger days. The bike has his old racing numbers as well as his nick name “Bullet Bob.”
