Battery cover lost?

[T-Selwyn-Davis]

Tody after Uni I came to climb on my motorcylce to get home and I found that the plastic cover that hides the battery was missing.
Wether it was stolen or just fell off whilst riding, i dont know!

I have tried looking online for a replacment but tbh i dont really know what its called. Any one know?
Another thing i was worried about is my motorbike's safety against theives. Is it possible to hot wire it with the battery exposed? Or would you recomend finding an alternative way to commute? :??:
