Change the status automatically after the add of a revision

I have 2 forms, the first is the form motorbikes with 3 fields (matriculation, number_motorbike, status).

Then, we have the form revisions with 4 fields (date_revision_start, date_revision_end, garage, fk_motorbike)

Here in the form motorbikes the status of the number motorbike must to be automatically unavailable.

I must to work on which controller to automate the availability status of the motorbike?

Motorbike Controller

    public function index()
    {
        $motorbikes = Motorbike::latest()->paginate(5);
        return view('admin.motorbikes.index', compact('motorbikes'))
          ->with('i', (request()->input('page',1) -1)*5);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
   public function create()
    {
        return view('admin.motorbikes.create', compact('motorbikes'));
    }

    /**
    * Store a newly created resource in storage.
    *
    * @param  \Illuminate\Http\Request  $request
    * @return \Illuminate\Http\Response
    */

    public function store(Request $request)
    {      
       $exists = Motorbike::where('matriculation', $request->get('matriculation'))->where('number_motorbike', $request->get('number_motorbike'))->where('status', $request->get('status'))->count();

       if (!$exists){
            Motorbike::create($request->all());
            return redirect()->route('motorbikes.index')
                ->with('success', 'new data created successfully');
        }

        else{
            return redirect()->route('motorbikes.index')
                ->with('error', 'doublon');

        }   

    }

Revision Controller

class RevisionController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $revisions = Revision::oldest()->paginate(5);
        return view('admin.revisions.index', compact('revisions'))
          ->with('i', (request()->input('page',1) -1)*5);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()            
    {

        $motorbikes = Motorbike::all();
        return view('admin.revisions.create', compact('motorbikes','revisions'));
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
                'date_revision_start' => 'required|date',
                'date_revision_end' => 'required|date',
                'garage' => 'required',
                'fk_motorbike' => 'required'

        ]);

        $exists = Revision::where('date_revision_start', $request->get('date_revision_start'))->where('date_revision_end', $request->get('date_revision_end'))->where('garage', $request->get('garage'))->where('fk_motorbike', $request->get('fk_motorbike'))->count();

        if (!$exists){
            Revision::create($request->all());
            return redirect()->route('revisions.index')
                ->with('success', 'new data created successfully');
        }

        else{
            return redirect()->route('revisions.index')
                ->with('error', 'duplicata');

        }   
    }
