This is a brand new motorcycle. It builds upon the knowledge gained with my previous bikes, but where those were a proof of concept, this is the final product.
This 1/8 size Racing Motorcycle is far more advanced and has been completely redesigned with knowledge gained from actual RC motorcycle designers and racing enthusiasts whose invaluable input was incorporated into the design. This is not meant to be a good 3d printed RC motorcycle, but a serious new RC Motorcycle variant that people can build, design and race at the track.
Built and Engineered by:
Step 1: Overview
NOT JUST BIGGER, BUT BETTER—COMPLETELY REENGINEERED AND REDESINGED!!
Every part of the bike has been redesigned, and re-imagined to make this bike stronger, more robust, more realistic, to make this RC motorcycle drive, lean, and use rubber tires.
Building this bike to an industry standard size allows the use of off the shelf parts, dampers, shocks, wheels, and tires.
Different color combinations that mimic the rear Suzuki race bike livrey.
CHOOSE YOUR RIDER
You have two choices of number plates #25 (Maverick Viñales) and #41 (Alex Villà), so you get to decide who you want to represent!
The body was redesigned to make the bottom of the bike narrower to allow maximum lean.
DESIGNED TO BALANCE
All of the weight is tucked in towards the center of the bike to allow it to easily balance.
THE STEERING HAS BEEN CHANGED
A spring loaded servo linkage has been added along with a dampener for smooth steering input.
BOLTS NOT GLUE
Unlike my other 3d vehicles, this bike relies on bolts rather than glue. This makes the bike easier to build and maintain, and it aids in the bikes strength.
BUILT IN THREADS
Fusion360 gave me the ability to add threads to the design so the holes print with holes already tapped. (cleaning up the treads with a tap is still recommended)
This bike was built with crashing in mind. Parts are bigger and the body parts are one piece so it can withstand crashing and rolling over.
This new bikes has a chassis that the body parts bolt onto just like a real bike. The bike can be broken down to the chassis in less than 5 minutes by only removing 9 bolts. This allows easy maintenance, tuning, and testing.
55MM REAR ADUSTABLE SHOCK
Bigger rear shock for better dampening.
You can adjust the ride height, steering angle, rear shock ride height, rear shock mounting position, front fork angle, and even the camber of the rear wheel.
METAL RACING FRONT DAMPNER
Racing front dampers are used in the front forks because this bike was meant to use serious racing parts.
WIDE SELECTION OF RUBBER TIRES AND WHEELS
The last bikes suffered in the lack of available rubber motorcycle tires, not this bike… any 1/8 tire or rim will fit and can be used. From 3d printed rims with Kyosho rubber Tires, to GPV-1 tires, to even GRP’s carbon rims and super sticky tires. The bike can be configured in with a regular rear rim or even use a mechanical gyro in the rear if you are new to driving an RC motorcycle.
Weight 770 grams/1.7 pounds
Step 2: Parts List
Step 3: Manual
Step 4: 3D STL Files
Step 5: Printing
It's recommended that you use a 3d Slicer that allows you to place your supports like Simplify3d.
The parts are orientated so that the print layers align so you get a nice finish.
If you have a heated bed:
Print PLA @ 60-70 C
If no Printed Bed:
Use a bed material like Printinz Bed Plate, build tack.
All printed parts were printed at 100% infill to add to the robustness of the bike.
Print Time with 1 printer: 2-3 Days
Assembly time: 1-3 hours
Real Blue, Real Black, Transparent Yellow, Real Red, Real White, Metallic Grey/Metal
I used Solutech Filament because I find that their colors are very true and very rich.

Hitec HS-311 Servo
Servo Arm (Main)
Servo Arm (desired degree 62.2, 64.7, or 67.2 degrees)
Motor: 5500 kv or higher
Step 8: Assembly: Motor
Step 9: Assembly: Transmission, Belt, Pinion Gear, Rear Shock, and Rear Swing Arm
Step 10: Assembly: Rear Wheel and Drive Gear
Step 11: Assembly: Front Wheel
Step 12: Assembly: Front Fork and Fork Stem
Step 13: Assembly: Build Stand
Step 14: Assembly: Tripple Trees, and Finishing Body Frame
Step 15: Body Fairings
Step 16: Assembly: Radiator, ESC, and Receiver
Step 17: Assembly: Cut Servo Wires and Add in Another Connnetor
*Step only needed if using Movable Rider
Step 18: Assembly: Steering Linkage and Install Damper
Steering Link Assembly - GPV1
Printed Steering Link Servo Mount
Racer's Edge Aluminum Pro Single-Sided Servo Horn for HiTec (Blue or Black)
Step 19: Assembly: Install Body Fairings
Screw in the main body fairing with (4) m3 x 16 set screws.
Tank with m3 x10 flat screw
Rear Fender with (2) m3 x 8 button heads
Front Fairing with (2) m3 x 8 button heads
Step 20: Assembly: Install Battery
Step 21: Finished Bike
Step 22: Check Alignment, Rear Wheel Camber and Balance
Check that the wheels are inline by placing it on a ruler or a line, adjust the wheels with different spacers if needed.
Rear Wheel Camber
Check that the rear wheel is not angled... If it is adjust the rear wheel camber by adjusting the two m3 x 8 button heads screws and adjusting until it is completely vertical.
Balance the bike on the floor. Check and see if the bike can stand up and hold itself without falling over. If it cannot stand, check the wheels alignment and rear wheel camber.
Step 23: Wheel Choice: Printed, Carbon, Or/and Mechanical Gyro
Wide Selection of Rubber Tires
The last bikes suffered in the lack of available rubber motorcycle tires, not this bike… any 1/8 tire or rim will fit and can be used. From 3d printed rims with Kyosho rubber Tires, to GPV-1 tires, to even GRP’s carbon rims and super sticky tires. The bike can be configured in advanced configuration, or if you are new to rc motorcycles a rear mechanical gyro can be used as the rear tire.
Step 24: Rider
Because this build is about the bike and the rider has remained the same, I'm going to leave the assembly of the rider to the manual pdf above, and keep the focus of this Instructable to the new 1:8 bike.
Step 25: Using the Stand to Start
The Stand was designed to both hold the bike during service as well as holding it standing when you are attempting to start the bike.
Step 26: Go Riding!
