I always use the front bumper and the rear hitch bkt. holes in the side by the diff.
My concern is mainly the rolling effect. I've got a 5' x 8' trailer and with the front tires pressed against the front rail of the trailer I can just close the back gate with no rubbing. Definitely going to need a bigger trailer but if the shoe fits...Keep in mind that your strap on the front if pulled straight down wont keep your bike from rolling back and forth and will work your rear straps loose. I did mine the exact same way a couple times and realized that my rear straps were always coming loose. You have to "pull the bike apart" to strap it securely.
I used to pull my wheeler all the way forward and pull the front down, this didnt work. I now have to leave a little space (1' or so) between my front tires and my tie down point to get the "stretch" factor i need. And i could actually use a little more trailer, i may have to take my divider out.
Hope this helps in any way.
**Edit** Note: my strap isnt tied to bumper, but my excess is.
Sounds like it could be a good time if you don't tell herI run through the wheels as well. I've never had a strap come loose even once since doing it this way. The bike doesn't even move.
Just make sure if you ask your wife\girlfriend to pull the bike off the trailer she knows she still has to undo the front straps.... She left some nice black rubber marks on the trailer before she realized she was still tied down![]()
