I thought I would re-post this review on this forum for those who have not seen it and are interested in adding a bit more leg room to their Chief platform bikes.

Thoughts on the install and impressions of the Aeromach floorboard lowering kit I got for my Dark Horse.

First some context - I am a shade over 6'1 and I found that I could do with a bit more length in the leg room department, it felt a bit cramped,  so I ordered the Aeromach kit. At the time I had a couple of thousand clicks on the bike and perhaps I would have got more and more used to it over time but I do like the new position.

Really the install is dead simple and you only need handful of tools.
  • 8mm allen key
  • 17 mm spanner
  • 10mm spanner (open ended)
  • 11mm spanner (open ended)
Don't forget lock tight on the bolts but not on the heim joints. I used some lubricant on them so they turn easily for adjusting the shift rod.

 In theory the install should have taken around an hour and I figured I had enough time to knock out it over on Sunday. The estimate was probably right but there were was a quality issue with the thread for the replacement gear linkage being dodgy and it took me just as long to solve this (left hand thread so I could not just run a die over it). Others have reported a similar issue.

Install is simple, I did the right side first and it was quick and easy. Hardest part was supporting the floorboard so that I didn't damage the brake line while I installed the bracket.

I used the original bolts with the nuts from the kit to fit the floorboard to the bracket as the supplied bolts are way too long IMO.

For those who are interested I have attached a picture of how the reduction in height at the floorboard (scraping point) so you can see how much corner lean you might lose. Most people say it is not noticeable but if you scrape with the stock set up it is something to be wary of. The pic is when it is on the stand so it is higher than riding position but the change would be relative. Oh and this is the second position, there is a mounting position with less lowering.

 I finished the job mid week. I planned to take the bike during the week, opened the shed to find bike that was not ready to go. I didn't have a plan B so I had to knock it over smartish.

Fitting was quick and easy, same as the right side but with the addition of the shift rod.

Make sure the heim joints screw on easily that way you can adjust the gear lever position by turning the shift rod. One end of the shift rod is left hand thread so it acts like a turn buckle, turn the shift rod one way to shorten and the other to lengthen. This will raise or lower the gear lever.
Turns out that the left hand thread is the rear one, I didn't pay attention to the instructions on this and put the shift rod in backwards. No real issue it just means the direction of turn for adjusting the gear lever is reveresed.
First impressions
Instantly seemed more comfortable and the difference was clear. I no longer felt like I needed to sit up on the back of the seat. I think it needs different handle bars to fully resolve the comfort for me but it is still a good improvement for small $, $220 at my door from Meancycles in the US. I think Zorro's has them in available locally.
It didn't take long to get used to and after a very short time it was hard to tell that I had made a change as the general feel of the bike was not changed (which I am pleased about).
Here are some before and after pics that I found on the US forum (credit to Enzo5000 for the photos).

My thoughts are that if you are thinking your Indian could use more leg room then give this some thought, it had made a noticeable improvement for me. It is definitely more comfortable but I did manage to find the road with the floorboard bracket. Although to be fair it was a road more suited to a super sport than to a cruiser and it was the first time I had ridden it on the Indian so l may well have scraped anyway. I bit pretty hard because the mates I was riding with said they heard the crunch. On a positive note; for a cruiser the Dark Horse handles the twisty stuff really well.
I will give it some more time and see if I get too much scrape but so far only once each side on a very twisty road, one was a minor touch on slow speed turn where I just dipped in too far.

I have now ridden on some pretty twisty roads in the South west and chased a Sport bike at up to 140km/h with no scraping so I am happy with the change, I am still a little nervous about when it might hit but it has not happened very often. There is no doubt you can find the ground but it has made me improve my riding style to compensate. I also adjusted the rear preload to the correct position (which was up for me) and that has helped buy some clearance.

Thanks Robbo
I did install this on my Dark Horse with the help of Chief10 as he had previously fitted them to his Dark Horse
Had no troubles fitting mine as threads were all good as well as helm fittings however Chief10s threads were tight and awkward and had to be replaced
Both of us are 6' and a bit and the extra leg room is welcomed with this Aeromach floorboard lowering kit
I ordered it from the USA and it came within a week
$200aud all up I think..☺

Any issues with scraping since you put them on?

I'm a cornering aggressive type rider and I know I would scrape my boards if I lowered them.

I am not sure how much clearance is changed really. the geometry of the lean angle means that the clearance on the turn is less than would be measured from the vertical lowering of the floorboards.

I find the biggest difference in low speed corners when you can tend to dig in to a corner rather than flow into it if that makes sense. Although there is one bend that I bit hard at speed but that was really sharp and steep camber bend on a really windy road that is an "On any Sunday" type run for Sport bikes and was before I adjusted my preload properly (it was actually a road called Obrien Road where Peter Brock was killed).

The other thing is getting used to the clearance and where it hits, I think that once you have ground in once there is an ongoing paranoia about when it is going to happen again.

I'm getting these but before I commit to the American site (about $200 USD delivered), is there an Aussie retailer?

I have them and they made my bike much more comfortable for me. I got mine from the US but they are now available from the Indian Dealer. At least they are available at the Perth Dealership.

Sounds like a plan. Are you going to the shop ride on the 25th?
Only the install pics are my bike the finished left and right side of the shiny chief came from Enzo on the US forum.
I also don't have Dark Horse 1.0 anymore sure to an unfortunate incident a year ago but 2.0 is going strong.

Hey Robbo, a question please.  Do you think this kit could be used to move the floorboards forward but NOT lower?  In one of your pics, I see you scraped the mount cornering.  I value cornering clearance so I do not want to lower them.

Hi V - No they are designed for forward and down so it would need a different shape to achieve just forward relocation and I am not sure that the configuration of the floorboard attachment to the frame lends itself to achieving a forward only relocation. It would need at least a minor downward adjustment to allow the bolts to clear the frame. The extensions have 2 positions to choose from so you can have a half way option.

However in respect to the scrape you noticed, that was actually done pre install on the stock height floorboards but it was on a very twisty heavily cambered curve chasing a sport bike (trying to anyway, the sport bike was still way ahead of me) . It was a hard scrape and the others riding around me heard it.

After putting the extensions on I adjusted the rear preload to specs and it gave me back some clearance, I only scraped a couple of times after that and mostly on slow sharp corners where you kind of dig in a bit as you turn in rather than flowing in to the turn at speed (that makes sense to me because I know what I am trying to portray). Oh that and when I crashed 1.0 but even with stock height floor boards I was going to scrape then. 2.0 has also been given a slightly heavier preload on the recommendation of the shop so it should help further.

I have yet to put them on to 2.0 but I will get to that soon (I have to put new bushes in the Shovelhead swing arm as the next priority) as they do make the bike more comfortable. Space was an issue for me and it felt a bit cramped . I notice that I ride with my foot over the end of the floorboard and it feels like it would be better positioning if I was sitting up on the back of the set, the extensions really help to sort that out.  I have to say that the Beach Bars on 2.0 have also made a difference so the urgency to put the floorboard extensions on is less.

I am not sure what they cost but I got mine from  the US in the early days (some of the dealers carry them now) and it was under $150 from memory so is well worth a try for the cost.

Thanks Robbo for your detailed reply.  We must be about the same height.  I'm 6'2" and when cruising, my heels are positioned just at the front edge of the floorboards.  I too ride with pre-load set firmer than many and my rear tyre is slightly higher profile than factory.  I still scrape from time to time and it is not a pleasant feeling.  If I could, I will raise my floorboards and inch or so... not sure when I will start to scrape the exhausts after that.

Hey Robbo and V_Twin, im 6'1" and like u guyz i pondered the question of leg room and asked at the shop, they only had the lowering kits,so i came up with my version, which is the whole assembly 2 and 3 inches forward with the ability to tilt the heel down, im still working on moving the floorboards themselves 2 or 3 inches more as i scrape when i get excited, ill get on my puter 2 nite an do some pics

That might work for some... for me, it would be uncomfortable to hold on to the handlebar on a long trip.

I hear you

Handlebar pull backs?

The only reason I say this is because I think pushing the floorboards too far forward might look odd.

What about highway pegs?

oki doki lets give this a shot20171130_185905.jpg 20171130_190332.jpg 20171130_190959.jpg 20171130_191009.jpg 20180110_090853.jpg 
so from the 1st shot standard position, to the bracket, to the shifted floorboard, then angled down on the heel and thats shifting the whole floorboard and gear shift and on the other side the whole brake assembly, luckily the brake line is long enuff, you also have to lengthen the gear linkage. I also dont have crash bars otherwise id have to redesign them as well. Our perth mechanic said he didnt like them for around town, but would be great on a long ride,but i love them, i also ride in the rain and there is nothing worse than your foot sliding forward under heavy braking, but with the angle your on, they dont move, I do need to move just the boards forward though, just cause my feet hang over the end lolol. So just a basic bracket with 2" and 3" forward adjustments, and you will scrap the floorboards on the steepest angle, the other reason I did this was cause i wear ankle boots and the way they were, they dug into the back of my ankle, now no probs

yeah Robbo I will be going on the ride on the 25th. hope to catch you then, im easy to spot, long haired lout on a DH and probably the only Kiwi lolol

Love your work Cloud.
I had wondered how to get around the frame for a forward only movement but now I see what you have done it makes perfect sense.
I reckon there would be a market for these if you wanted to cash in.
See you on the 25th. I am easy to spot also

Remibds me of pegs because of the angle. I have actually asked the question about swapping to pegs instead of floorboards.
