Chassis—The metal parts of the newer flip top trailers are much more rust resistant than the metal parts of the older ones.  That’s because starting with the 2009 models, we powder coat all metal parts instead of painting them.

Floor—The floors in the newer flip tops are much more durable than the floors in the early flip top motorcycle trailers.  We changed from ordinary OSB (oriented strand board) to ¾” Advantek.  Although it costs nearly three times as much, we believe it is worth every penny as it is much, much more resistance to moisture and consequently has a much longer useful life.  These days the floor is actually a sandwich with Advantek on the bottom, fiberglass in the middle and a gelcoat top, complete with a non-skid pattern molded into it.

Tail Lights—We replaced the two round LED tail lights on each fender of the older flip tops with one vertical LED light bar on the newer ones.  Not only did this update the look of the trailers, it cut the number of necessary connections, and hence potential corrosion points, from twelve to six.

Interior Lighting—We recently replaced the plastic light fixture mounted overhead about halfway to the rear on the flip tops with a new metal fixture light centered just over the top door jamb.  Since the plastic fixtures were prone to periodically “shed” their plastic cover, we replaced them with lights whose covers are held on by screws.

Tailgate—We added a retaining clip to the steel circle around the D-ring handle to keep the handle from dangling when the tailgate is lowered.  The problem on the earlier flip tops was that if the front end was raised enough, the D-ring handle would dig into the ground or pavement.  So when a bike was loaded with the D-ring dug in like that, there was way too much stress on the fiberglass near the handle. The result was predictable—patches of stress cracks about six inches 45 degrees downward and outward.  Now as long as you remember to secure the handle in the retaining clip, that can’t and won’t happen.

Wheels—The spoked aluminum wheels on the newer flip tops are much more rust resistant  than the chrome plated steel wheels on the early trailers.  A side benefit is that they use regular lugs which are less prone to surface cracking and other cosmetic problems than the chrome plated lugs we use on the original wheels.

  1. Id like to know how much it would cost for your one bike fiberglass shells. I have a BMW k1200 LT. Big heavy bike.I would need it shipped to Encino Ca. 91436.
    Thank you. This is just what I NEED

  2. I have a 2005 single flip top Ironhorse trailer and love it. My question is what would the cost be to upgrade to a 2015 single. Or a double.
    Price for both would maybe help make up my mind. Thanks
