I just spoke to my brother and he told me that a bunch of his friends at work have the 1800C model and he's pretty much sold on their advise. I've told him I'd put it out on this board and he can hear it from the guys and gals that have the 1300. He rode mine and the 1800. I briefly told him about the differences so I put it out to all of you. Don't want him to regret his choice if he chooses the 1800. Thanks all for your input. No matter what his choice, well have another member on this board. Ride safe.
