You’ll be grand. The only things I can’t get in my Vito are Multistradas, even with mirrors & screen removed.
I used to pop my GasGas ec300 in my Vito for Green laning. Other bikes included a 749, Monster, KTM 790 the most awkward was a Honda Transalp which required mirror removal.
It’s the mounts the screen fixes to, they, and the brake reservoir are just too high by about 50mm to get in.
