2016 Suzuki GSX-RR 1:8 Racing RC MotoGP




About: I am passionate about racing cars and racing technology. I build designs that hopefully shock and amaze the 3d printing world, in an attempt to push the limits

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:

Brett Turnage



Step 1: Overview


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.

1/8 SIZE

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.


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.


All of the weight is tucked in towards the center of the bike to allow it to easily balance.


A spring loaded servo linkage has been added along with a dampener for smooth steering input.


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.


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.


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.


Racing front dampers are used in the front forks because this bike was meant to use serious racing parts.


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.

Step 6: Bike Assembly Overview

Step 7: Assembly: Body Frame

Parts Needed:

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!

    Hugely detailed, how much work went into design in hours for like the front forK does the software say? or did you keep a record?

    I want to get a model to design a front end but I need someone with drawing and machinery to build parts skills.

    No all you need to do is update it with Andrea Iannone's 29 and not put it together so it looks like it crashed!

    Seriously, this is totally cool and really rad. Will be writing about it on 3D- Racetracks This is an awesome instructable.

    Thanks man. I guess a person could build it and throw it against a wall a couple of time to get the right patina of race damage. Although I'm pretty sure it affect the drivability, to some degree.

    Really cool stuff your doing there. I checked out your site and followed you guys on twitter. For race fans, having replicas of tracks is super cool.

    I know right I wish I could have two printers or even one for that fact! This is extremely impressive and I wonder how fast you can push it?


    Reply 2 years ago

    you should try to build your own 3d printers... I've been many, but you can get a good printer for $200 now days. There are some really good ones for cheap.

    Thank you. It took a lot of work and it's always continuing to refine it. It's pretty durable, 3d is not fragile if the parts are designed and checked in stress analysis. I designed it to be robust, so it can take the hits, roll overs and still be okay—crashing is a fact of life in RC so it has to be able to survive it. As far for speed, I currently have it geared where it theoretically it might hit 40mph, but haven't clocked it yet. Hope to get videos of it up soon.

    Thanks! I've won one printer in one contest. Who knows the what final results will be. I think there are some really good builds in the competition, especially your hand which I thought was amazing... I left a comment a few weeks ago when you posted it... I thought your Fusion work was great and the print quality was amazing... I think it's clear that you can quickly become a master of Fusion and CAD... it's very impressive work for a first build. I'm still a relatively newbie to CAD... I've been working with CAD for 1 year last month, so I think your future is bright and I'll be watching to see what you can do and come up with next. I think you definitely have the skills to really be amazing at CAD and pushing 3d printing and design forward which is the whole point of all of this... pushing a new consumer industry into new areas, and inspiring others to use and see the benefits of CAD and 3d printing in prototyping, design, and manufacturing.
