I have water-proof overtrousers but the problem is that if I ride in heavy rain or the roads are quite dirty, the bottoms of my trousers get a bit wet/dirty. This has never been a problem before as I have always worked in a factory and went to work in grubby clothes anyway so it didn't matter. Also my coat is only "shower-proof" and if I am in heavy rain I get a triangle of wet in the middle of my chest area. Obviously this is no good on an expensive suit so I would like to know what bikers do if they have to wear a suit to work but also go to work on a bike.
Thanks for any suggestions as I am totally at a loss.

Cheers

PS: Have Honda bought out a silver Firestorm? I swear I have seen two in the last week - didn't get to look close though but they looked new with a slightly modified shape - definately Firestorm-shaped though (looked really nice).
