My insurers (bennetts) define garage as brick built, but maybe if you called one you might get some allowance as extra security or something?
as a fun side story, my friend lived in Westminster in an apartment block that had a private underground car park with gated entrance, CCTV and 24 hr security and his insurance company said as other people had access to it they classed it as street parking and quoted him NINETEEN THOUSAND POUNDS for his bike (brand new Kwak Z1000)
also good luck with mod2! remember your life savers and even if you think you've messed up keep going! often it's not as bad as you think!!
