The Ax-25 blaster cannon represented a specific blaster cannon design manufactured by BlasTech Industries. The C-PH patrol speeder bikes, which were built by the Aratech Repulsor Company on behalf of the Galactic Empire, came standard with one forward-facing, permanently mounted Ax-25.
This Ax-25 blaster cannon was designed specifically for the 2018 movie Solo: A Star Wars Story, with its unveiling taking place earlier in that same year within the initial trailer that was launched for the film. The weapon's designation was confirmed in the reference publication Solo: A Star Wars Story The Official Guide, authored by Pablo Hidalgo and made available alongside the release of Solo.
