Salt is probably not terribly corrosive.
Howdy, y'all in the GTA.
I ride a lot in Toronto, but not in the months that are Brrrrr and Airy, thank you.
I have a 1984 Honda CM250 that was my daily ride, all year, in Toronto from 1985 through 1989. I rode it from Lawrence to Steeles and back just about every day, and I probably didn't wash it all winter. I recall chilly days when the cars were skidding worse than I was. Pedestrians were having a rough time, but I sloshed and slurped my way to work, and I was the only person in my department to reach work on time.
The bike is still with me, and has 40000 kilometers on it, and I ride it at least every week. I had to replace the exhaust system, for about US$250, because it rusted away in several spots. The rest of the bike is a tad rusty, but I could wash it thoroughly, brush the loose rust away, and make the frame look almost new with Tremclad paint.
If you ride your Strom through Toronto's winter, expect some alloy parts of the engine to show pitting, and make sure you put some grease on moving parts such as the gearshift linkage and the sidestand. Apart from minor pitting, your bike will probably not show any noticeable corrosion from the salt.
A suggestion: get a tin can and a magnet, and fashion some armour for your exposed oil filter if you have a 650. A fellow in New England had some debris pierce his oil filter! The loss of oil and the decrease in traction would not help you ride, especially in the winter!
I say GO FOR IT ... but of course I am saying it in Florida.
