Yamaha R1 titanium swinging arm spindle
This is a Yamaha R1 swinging arm spindle with nuts and washers I made. The shaft was a bit of a challenge, but i’m pleased with the way its come out. The main trickiness of it was getting the fat thread right, without the frame to try it in i had to cut the thread to match the OEM nut, so i expect it will be a bit slack in the frame, which is better as it will allow alignment.
