Lemme tell you about rain
Picked my B'man up on a friday evening in a light shower. Rode it 94 miles home. More nervous 'bout a new bike and not having ridden in three years but the B'man handled it better than I did.
I made an appointment to have the 600 mile service done the following saturday, 8 days away. Rode to Jacksonville the morning after I picked it up, 250+ miles. Rode home on Sunday. Rode to work all week.
Saturday morning, 5AM, morning of my 600 (850 mile) service, WOW, monsoon! Suited up, rode from Charleston to Sumter, SC.... 94 miles, hard rain every inch of the way. Did it in 1 hour, 50 minutes. The bike has no problem with the rain. The tires are excellent in the Rain. But the windshield wass a little low, rain came off it, right onto my helmet visor.
I have since changed out the windshield to a GIVI, and it took care of the blow back from the windshield. I would venture to say that I am more of a liability in the rain than the B'man. It handles the rain fine! Me, my knees hurt.
