ramp kits work fine with trailers, heck i used to use just a plank no ramp kit to put bikes in my trailer. however, if you are using a truck, no matter what your bike will scrape, even if you dont have fairings, i can guarantee bubba that your f2 will scrape, remember puttin that one in the back of my s10 with a plank? yeah the next day i bought ramps cause i was so sick of doin that. but honestly, ill give you that ramp kit for like 10 bucks cause i paid like 20 for it, and you can make a real cheap ramp. but if you wanna protect the bike, cause your f2 looked really nice, i would get real ramps, its a good investment. like i said, mine were like 120 for 2 ramps, and im glad i have 2...one to walk up and one for the bike, makes it so easy.
