Warning! - floor board extenders are bad idea

I installed the 1" floorboard extenders (moving floorboards out 1") over the winter. They did come with a warning about losing some of the ground clearance in corners. Today was the first chance I had to get the bike out in a couple months. I made it exactly two blocks from my house, and making the last turn to leave my neighborhood... I ended up slammed to the ground and the bike slid for approximately 15 feet (I was doing a california roll through a stop sign so I was going less than 10 mph). I now have a bruised shoulder and knee, my neck and back feel a little tweaked as well. Luckily my leathers took all the road rash. The bike on the other hand... well it is F'ed up. Right side highway peg, crash guard, lower fairing, muffler and floorboard are all scratched pretty bad. The front fender got scratched pretty bad but the saddlebag took it the worst. Not only is it REALLY scratched, it cracked it vertically on the front side of the bag. Two big nasty cracks running top to bottom of the bag.

The $45 spent on the extensions was definitely not worth the couple thousand it is going to take to put the bike back together.

I am sure there will be someone pipe in here with "I have had those extensions for 2 years without a problem" but this is not for you guys... This is just a warning to the people that are thinking of purchasing the extenders.

Good day to you all and ride safe!

Wow.... first, glad you're basically ok, I don't have extenders, but if I ever think about getting them, I'll remember your thread. Keep us updated on the repair of your bike.

I was thinking of getting those(before). thanks so saving me several thousand. I have CVO paint so I'm sure it would have been an even bigger mistake for me. Glad you are going to recover and I hope you find some good deals (or some great mods) as you fix the bike.

Before we get too far down this road, I've got to say that there must be more to this story. I can't imagine that one inch board extensions are the sole cause of this. Even with the extensions, the boards still touch down first and they're still hinged.

As a disclaimer, yes I actually have been running the extensions for two years with no issues. Then again, I'm also running Banana Boards, which I think are slightly narrower than stock, so maybe my setup is a wash.

Anyway, glad you're ok.

I'd have to say you are right on the money. I've had them for almost as long as I have had the bike (a bit over 3 years now), and I have put over 65,000 miles on them. I do have some scraping on really severe leans (scraped them 1 time on the Dragon), but always at the bottom outer edge of the board, and it always flips up on contact. I would have to say they are probably one of the most comfortable upgrades I have done.

I'm curios as well, I've had them on a couple of my HD's - when you have size 13's they truly help, never had an issue - put well over 100K with them on - was the board locked somehow, like the other post why did it not bend?

I have them on my RGU for three years and did some pretty good leans and never had a issue with the one inch extender. Doing low speed there is no lean and I don't get it. If you lived in the snow belt I would say you hit a patch of road sand. Not many of us are riding since we have another month poor riding conditions. How can the extenders be the problem?

Man that really sucks. HOpe you get the bike fixed and you heal quickly!

Ive had footboard extensions on 2 bikes, my 06 Street Glide and now on my 2010 road Glide.
Because both of these bikes have lowered rear suspensions, with the extensions on, the boards scrape all the time. And not just the boards, the actual arm or mount of the floorboards scrape.
This was especially scary for me on the tail of the dragon on my 06 street glide, as i darn near lifted the rear tire off the ground as my back end slid out by scraping the footboard mounts.

So dont assume its only your footboard dragging or scraping. It could be the footboard mount too, and could make you slide out, as TitusPollo is saying.

So because of this, ive been thinking about how to make different footboard mounts and a thinner footboard. thats what i want!

Glad your not too banged up. Like others said , bike can be fixed. I still don't get how your leaning that far over at 10 mph. You sure you didn't hit some loose sand ?

Had extenders on the last three bikes. But they were the type that moves the board only, not the mounts. On my 08 Ultra, I sliced the tabs off the floorpans and re-welded them to put the board where I wanted it. I could see how moving the mounts out could be an issue but the board should fold up first and give some warning.

As others have said, there must be more to this story.

Another data point: Since 2006 I've put 1" floorboard extenders on my last three touring bikes for over a combined mileage of 60K. When I ride I don't corner hard like a sportbike, but on occasion have slightly scrapped my boards while turning. Never once have I experienced what the OP has related.

regards,

Slow speed corners

You can scrape boards at sub 10mph without extenders fairly easily. Watch some of the bike rodeo vid's , especially the LEO competitions. I have one bike with and one without the extensions. Scrape the hell outs the boards on both. It's a non issue. Merely a heads up your approaching the max lean angle before grief begins. Problems begin when you run out of board movement and start to scrape the hard bit's. i.e. the board mounting arm.
Any extenders I've seen would still let the board pivot up and detract close to zero from allowed lean angle before hard bit hit's.
Sincerely sorry to hear about damage to bike and yourself, however really doubt the root cause was the extenders.

First off...glad your were not seriously injured...sh*t happens sometimes.. but as others have stated, I don't think the extenders were the root cause of the wreck. I have had mine on for over 30k currently with no problems. Seriously check the area of the accident for the true cause...sand, gravel, sticks, holes..etc.
Good luck on you and your bikes recovery!!

I am with the few others...I have had them on previous Ultras I have owned. I have scraped them, and it took some leaning to do it, but turning at a stop sign at 10 MPH?
Bad to hear you went down, but I balk at the idea it was the extenders only that caused it. I may be wrong. I wasn't there.
I do not have them on my current bike, except on the on the passenger
boards because they do decrease some of the heat felt on my wifes legs when at a stop.
