Ha! I've had the same thing with Harley-Davidson & a charity event I ran. It's only a set back, gotta think outside the box..
How about a generic vee-twin engine logo? Or the letters MOG? presumably they would be concerned about M3W too..
Pistons & crank in a vee?
Malverns Malt?
Just writing as I think here...if that's the problem you need a solution, so get those thinking caps on, team!!
