The Savage project is all about building a bike from scratch, using the all-classic 1 cylinder 650cc Suzuki Savage engine. This big,\u00a0lazy carburetor driven\u00a0cylinder\u00a0allows smooth handling with limited weight and size, and is beautifully classic looking. Being easy on the budget, it was chosen as the preferred horsepower provider for this\u00a0project.<\/p>\n

The challenge started with the design of a fitting frame.\u00a0We think that the most\u00a0beautiful bike is a strong and smartly designed bike, which still has maximum elegance. So after sketching all wild frame shape ideas on paper, 2D (Ansys) and 3D (SolidWorks\/Cosmos) models were\u00a0built to check strength and strain under all applicable\u00a0load scenarios. This analysis was used to further optimize the frame design to ensure a high enough safety factor under all circumstances.<\/p>\n

     <\/p>\n

    The design is kept strong, pure and simple – the right lines\u00a0and angles were sought, to get the right looks while keeping the bike comfortable. Sitting positions were emulated in 3D and tested later on with the first rough frame build. Feel free to download the desktop background pictures!<\/p>\n

       <\/p>\n

      So, time to start building! Frame material was carried into the TUDelft workshop. Starting with\u00a0the bare bones: cutting\u00a0pipes and\u00a0bending them to\u00a0the main chassis angels. Preparing nice tube end fits so the welding can be done neatly later on.<\/p>\n

        Ok, so making the frame pieces was\u00a0a nice exercise. Time to start putting everything together and check how it fits. The extra time that was put into exact finishing and of the frame parts paid itself back allright – the tubes fit like a glove!<\/p>\n

          Well - there's the bare start of the project: the first tubes were put together to form the lower part of the frame. Everything fell smoothly in place at the first try - even the double 3D bends!<\/div><\/div><\/li>\n

          As soon as all main parts were fitted together, the front suspension and wheels were added to check the main aspects of the bike – real life sitting position, ground clearance and such. As a nice bonus the project was used as one of the showcases at the TUDelft. Nice \ud83d\ude42<\/p>\n

            After some necessary redesigning, the engine mounts and frame reinforcements were produced. Having all main parts on the shelf, it was time to put everything in place. To assure that all welds are neat and safe, our certified friend Anton the Weldmaster helped us by\u00a0laying\u00a0all main structural welds. Better safe than sorry!<\/p>\n

                Once the engine has found its place, the tank, front suspension\u00a0and wheels are put\u00a0in place to check if everything fits according to the design. This build is only temporary, the frame needs to be painted and many details need to be finalized, but the intended design lines which were optimized on a computer screen, already look even better in real life. That’s a relief \ud83d\ude42<\/p>\n

                  The rear wheel holding plates are put in place and kept at somewhat the right distance using a threaded rod of the same diameter as the rear axle. The plates were point-welded for the moment.<\/div><\/div><\/li>\n

                  The tank, engine and wheels are put in place to see if the overall shape and angles still correspond with our design. We have some space to play around with the tank position.<\/div><\/div><\/li>\n
                • \"\"
                  Here, the carburator is installed with the custom made cilinder inlet. We had to make a custom inlet because the original piece did not let enough room between carburator and upper frame tube. This one fits nice!!<\/div><\/div><\/li>\n

                  Now lets take a look at all details that need to be worked out. Starting to work on the saddle, brake, front suspension elongation and the exhaust for example. Piece by piece, parts are made and put in place.<\/p>\n

                    How'bout this home made exhaust pipe corner! Small sections cut off under the right angle. Looks cool allright. I don't think i'll paint them, like the way the welding looks on the stainless steel! Nice and conventional.<\/div><\/div><\/li>\n

                    Next let's try to fit in the self made gear links. The plan is to fit in a hand shifter on the right side of the bike, but for now the footshifter is built in. I'm curious on what feels better.. so why not try both ways \ud83d\ude42<\/div><\/div><\/li>\n

                          The mechanics are lifeless without proper wiring. So, time to install all necessary components. The Dutch law requires a lot of safety features to get the license plate, so a lot of wiring and components need to be placed.<\/p>\n

                            So this is it! Everything is installed, everything works. The first test ride is driven, the bike drives beautifully, handles easily and sounds nice and rough! Although there are some concerns about the sound levels, we ship off to RDW for the final technical checkup. Here all required features and functionalities are checked, before a license plate is issued. On a separate test track, the bike’s brakes are tested, handling is tested and\u00a0sound level measurements are carried out. Also, this is actually the first time that the bike is driven this much \ud83d\ude42\u00a0Test results: everything ok except one test result: the sound level is too high. We’ll have to fix that and return for a second test!<\/p>\n

                              So after installing some top-secret, self made sound level killing features, the bike is ready for the second RDW check up!<\/p>\n

                              And guess what: PASSED!<\/p>\n

                                This brings us almost to the end of this project. Some optical tweaks will be carried out\u00a0after the license plate is put place, but for now, we’ve done it!<\/p>\n

                                The Savage project is all about building a bike from scratch, using the all-classic 1 cylinder 650cc Suzuki Savage engine. This big,\u00a0lazy carburetor driven\u00a0cylinder\u00a0allows smooth handling with limited weight and size, and is beautifully classic looking. Being easy on the budget, it was chosen as the preferred horsepower provider for this\u00a0project.
