Honda SP2 7075 alloy wheel spindles
7075 alloy is not recommended for rear wheel axles, the forces produced by the drive train on top of the forces produced by riding can be too much even for 7075. But this one is going on a bike that is rarely ridden and only then on track days with promises of regular inspections. Even so I can take no responsibility whatsoever for the outcome.
These 7075 alloy wheel spindles are for a Honda SP2 and are coated with Surtek 650
