Project Jibril: this project consists of two 3d printed RC motorcycles: the 2016 Ducati Draxter Concept Drag Bike RC and the 2016 Suzuki GSX-RR MotoGP RC motorcycle.
This project includes two bikes because the motorcycle world is very diverse. I hope that everyone can find one that appeals to them.
My friend Jibril is crazy about motorcycles, so this project was named after him as he was the inspiration for it. RC motorcycles are almost like black magic, the fact that they can ride and balance themselves is accomplished with gyroscopes (either passive or active), and kits like the Kyosho Hang on Rider brought realism by having a rider that actually moved.
This project remakes that magic for the 3d world with two 2016 bikes that were designed not as chassis, but as the individual motorcycles with unique parts that aim to recreate the realism of the actual bike.
Both the Ducati and Suzuki feature a 3d printed functional front fork, adjustable rear suspension, and drivetrain that translates power from gears to a belt drive system which turns the rear wheel. They stay upright by using a weighted front wheel which acts as a passive gyroscope, and both bikes have to option run either TPU 3d printed rear tires or a rubber F1 RC tires for better grip. This is just some of the beauty and engineering that went into the bikes, but in order to really make these motorcycles come to life, the rider has to move.
The Rider which is a 3d wonder in its own right. It works by having a brain, backbone, and pelvis. The brain is a super tiny ultra micro servo which is located in the head of the rider. It attaches to the backbone that is a metal rod which runs through the body and is attached to the pelvis, translating the movement of the servo.
More than just realism, The Rider steers the bike. The lower left arm is attached to the main servo, and it moves the arm forward and backwards. This movement turns the handlebars which steers the bike. When both bike and rider are married together, you get an amazing experience of two futuristic race bikes that were never available to the public with a rider who’s sitting on the bikes in the way an actual rider would.
This project has taken me over 5-months of work, lots of iterations, multiple different bikes, many older versions that will never be released, and months of testing. These two bikes are the result of all of that hard work. I hope you enjoy it, I hope you are inspired by it, and I hope that in turn you inspire others.
