This is for adding a 140mm disc brake to bikes without them.Its original intent was for adding front brakes to small electric kids motorcycles for better stopping power.Designed for the MX350 to use the MX650/RSF350 brake calipers or regular bike calipers with the appropriate adapter (without the cone washers).Of course you can use larger discs by using different adapters.

I am including instructions for uploading to SendCutSend for getting manufactured.

Dimensions:

• Thickness: 3mm
• Axle hole: 10mm
• Adjacent to axle hole: 4.2mm (M5 tap)
• Fork fastener holes: 3x 5.1mm (M5 clearance)

I dont recommend braking while going in reverse as you are relying on the threads or rivets to not pull out of potentially thin-walled steel tube. This is strongest in the direction of the normal braking forces.You can also skip bolting and riveting by welding if it is made from mild-steel

Models:

• .dxf of the mount for cutting and bending
• .stl of the mount for mock-up
• .stl of a version of the 160f/140r caliper adapter
• .stl of a couple spacers
