My BSA Super Rocket had a chain guard which shielded both runs of the chain from any wash off the tyre. I added a pipe from the oil tank breather onto the lower run of the chain, and any vapours kept the chain nicely oiled. Only a little marking the ground. The chain stayed happy long term, little adjusting needed.
I would like to shield the lower run of the chain on my Rapide similarly, but it does not look easy.
