Yamaha R1 7075 alloy rear wheel axle
As we all know 7075 alloy is not recommended for rear wheel spindles. The added forces from the drive can be too much for them. But this is for a track bike, it will never see the open road, on top of that it will be removed after every meeting for tyre change so can be inspected and checked before every outing. Even so i can give no guarantees as to how long it will last or the manner in which it will fail should it do so.
Its very nice though…..
