Clearly that is not true. Marketing-speak.

They've always contended HD's door bars do nothing. Obvious in this thread it's not true. Sure it bolts in only two places but it triangulates the door and rear bulkhead openings. Now they have theirs and it bolts in four places. It may be better but it sure looks fugly and a whole lot tougher for entry and exit.

Nice idea from a purely mechanical standpoint but I do not like the look at all especially with the lettering cutouts. I still prefer the ones I have.

OK read the description..

I Recall reading that boss frog was against the idea of door bars. I guess not anymore.... They call them frog ribs :giggle:

I realize this thread is older then dirt, but I've got questions.
Has anyone tried bossfrogs door bars, are they better then the hard dog door bars? Would they even fit since I've already got a HD rollbar?
How do door bars effect handling? Do they promote/diminish oversteer or understeer?

The mounting point on the BF door bar does not match the HD rollbar and vice versa. BF has two bolts and HD has three.

Thanks.

Any comparison of the HD Doorbars vs the DIY Roadster Bars?

I read over at m.net, the roadster bars are easier to get in and out of. However, it has a larger outside diameter.

Any interference with driver seating position?

Does the DIY Roadster bars bolt directly to hard dog roll bar mounting plates?

Yes, they do. I found them pretty easy to get in/out with stock seats. You slider over them and seat bottom is almost level. Because they angle out, I'd think there is more space with the DIY ones, but have not seen a HD bar in person. Also keep in mind the DIY ones will interfere with NB door pockets, again due to the bend. You can notch the plastic.

Good to know, on my bucket list of things to buy.
