Introducing Motorcycle Foot Anchors

I think it would be a completely different riding experience, and that it would probably be cool transitioning side to side.
However, personally I would feel that my knees and/or feet, and ankles would for sure take a good injury in a crash.
I wouldn't want to have my feet somewhat anchored. Again that's just me personally. I rode dirtbikes for many years and a couple seasons of 250B mx. About 19 years of street riding, and stunting/wheelieing that just transitioned from dirtbikes.
So knowing how many times I've been down over the years on dirt:laugh: the idea of being stuck to the bike gives me the creeps. I much prefer to be flung throught the air or slide across the ground:laugh:
Anything can happen and/or kill you in a crash, but having something to help keep you on the bike could keep you on it during the crash. And enough to cause you much more injury than you likely would have sustained had you been easily thrown off the bike.
Considering it is designed to help you corner, it may increase a riders confidance much quicker than their ability, resulting in a higher crash rate.
That's just my two cents, if it's worth that.
I'm not trying to be negative, criticize, or bash your idea either.
I think it's great that you came up with the idea, designed it, machined it and have them on the bike.
That in itself is a noteable accomplishment.:beerchug:
I wish you well with your project.

Hey sixpack577, what you are describing is absolutely a valid concern, and don't worry I don't take it the wrong way. I devoted a lot of time researching the safety aspect, analyzing videos of various crashes, highsides, lowsides, and a lot went into the design to make sure the rider's foot would not get stuck in a crash. I'd like to point out a few major factors virtually preventing a rider's foot being stuck under the foot anchor.

1. The distance between the footpeg and the foot anchor is a lot smaller than the rider's foot, so even trying to get your foot stuck there on purpose is virtually impossible.

2. When the position of a foot anchor is correctly adjusted, and a rider places his/her foot between a foot anchor and the shifter/brake pedal, there is a bit of a play for the foot so that the rider's foot can stay there freely without exerting any upward pressure on the foot anchor and without exerting any downward pressure on the shifter/brake pedal.

3. The indentation on foot anchor surface makes it very slippery in forward-back-forward direction or in upward-downward-upward direction, even with some upward pressure on the foot anchor.

4. If you hook your foot under a foot anchor in a turn, muscles of your foot/lower leg is the only thing which effectively holds your foot in place under the foot anchor. The moment you relax it, either consciously or as a reflex (when a rider is about to crash), the foot simply slides out from under the anchor.

Having said that, I recognize that my projections is merely an educated guess as I honestly don't have crash data to support my contention. And as I was joking earlier, when utilizing foot anchors, the bike is so stable that no matter what I do it just wouldn't crash. However, I put my money where my mouth is, so to speak, and have enough confidence in my safety to ride with foot anchors for almost a year, both on the street and on the track, and can attest in doing so faster than ever before. For example, a turn I used to take at 90 (and of course, we are talking about the track, officer), I easily take at 105-110, and have a feeling that could go up to 120 easily. There are some turns which are quite bumpy. Before, I always felt uneasy in those turns, but now I simply shrug it off, let the bike handle it, while I am hanging in there having nothing else to do but to wait when the turn is over.

Oh, and thank you for the compliment! I've never imagined I would be machining stuff in my garage, LOL...

I don't usually say anything negative about things, everyone has their own plan, but it's,,,,,,,,,An answer to a question nobody asked.

I usually understand what I read right away, but I read it three times, and still not sure. There is also saying that if you don't have anything good to say...
 
never felt the need for such a thing myself. wore out a few sets of pucks at the dragon without it. but to each their own
 
Rossi, Stoner, Marquez don't use Carbon Fibre wheels either. I think we should let BST and Dymag know that they probably don't work... what's the use in trying... Oh heck, let's go back to drum brakes...!

LOL
 
So that's why Rossi, Stoner, Marquez etc are all so slow, no Foot Anchors.

Those guys have massive talent, which we don't have. The point is can things like the anchor pegs make it easier for us mortals to go faster safer and easier. Where is Tuff on this issue? We have a lot of track guys on the site - would be cool to do a test.
 
Based on my discussions with fast guys, many of them feel there is no need for foot anchors. They can go fast anyway. Except for a few, they also seem to be very close to the idea - there is one right way of doing it, and the case is closed. However, when I start pointing to specifics how foot anchors work and how they could be going faster, they seem to be unable to give a meaningful answer and resort to things like I am too slow and have no idea what I am talking about. To me, this is a red flag, because if someone understands the dynamics of riding, they could easily explain why foot anchors wouldn't work.

Here is a picture from Sport Rider magazine newsletter I got in my email a couple of days ago, and you can find other similar pictures printed on SR cover over the years:

Here is another one:

You would think the pictures show pretty fast guys. This is a typical body position I see in many riders, including fast ones: while the butt is hanging off, the upper body goes right back to the bike with the head atop the tank. I had such riding position. Now, don't tell me that if a rider in those picture moves his upper body to the inside of the turn and down so that his head faces the inside mirror or even farther away from the bike, that would not reduce the lean angle of the bike, or would not tighten his line, or would not allow him to go faster for the same line/lean angle! And if you say it wouldn't then please explain why not, and at the same time please explain why riders hang off the bike in the first place.

The deeper question is why isn't the rider moving his upper body so far to the inside of the turn? Simple: he would fall off if he attempts to do so because he has no way to hold on to the bike. That's where foot anchors make it possible. And you really have to experience such effect to appreciate it. The bike starts pulling to the inside as if you ride on the banking of a track with positive camber.

Now, I do recognize that some riders with long legs, and/or being in great athletic shape, and having tons of track time can figure out how to accomplish it without foot anchors, and I've been shown pictures/videos of such guys somewhat close to the body position I am talking about. There is only one problem: there are very few of them. The rest of us will never achieve this.

Tony, comparing one rider to another is useless. The claim is that the same rider will go faster than before, and yes this includes the racers you mentioned. I've experienced such leap jump myself. I ride faster, safer, with more confidence, and stability than ever before. And that's a fact, my friends, which I cannot ignore!

Here is the picture of Rossi from some years ago.

And here is the photoshop of the same picture showing his body position if he deployed foot anchors.

Don't tell me he wouldn't be able to take the same turn faster! When I presented similar argument to fast guys, they said: Oh, he must've been on a cool down lap. Yeah, right! As if I didn't watch so much MotoGP footage over the years.

And BTW, remember instances when a rider falls off or almost falls off the bike during shakes/slides in the same MotoGP footage (I researched 2011 footage in detail)? Notice how the outside foot/leg goes up first. Why? Because it has nothing to hold on to. During shakes/slides the rider's body starts moving around and bouncing on the bike, creating unwanted inputs, and promoting the instability. This would've never happened with foot anchors. Many crashes could've been avoided in the first place!
 
Side car guys demonstrate really well the principle promoted by foot anchors because one of the riders doesn't need to hold the handlebars, but rather devotes all effort to shifting the combined CG of bike/rider system to the inside of a turn.

And before anyone jumps in saying that it's the whole different ball game because the bike is never leaned in a turn, then I will ask what is the effective lean angle of the entire bike/rider system relative to the ground? Hint: it ain't 90 degrees.

A short time ago, I sent out kits to 3 separate members who indicated their desire to give this a shot. Hopefully, we will get their feedback within a few weeks.

I'll take a free test kit for a 2006 GSXR 1000. You know for my all knowing feedback :laugh:
 
I do think the new style of riding has riders way off the centerline of the bike. When I turn my head is usually at the grip, and I'm no athelete. The bike just feels better turning that way.

Tires they ride on have so much grip that the bike will take pretty much any lean angle... until the inside leg is right between the bike and the road. What then? The only logical choice is to try moving the rider's body way to the inside to gain a bit of advantage against the next guy.

If you are serious about it, and willing to give this a shot based on what you read on the website, we can make it happen. PM me. I have a design for last gen K1, I think 2008 - 2014. Not sure whether yours fits that, but I am sure we can figure it out. I could make a kit for you in a few days once I know the dimensions and layout of the footpeg area.
 
If anyone watched today's MotoGP, around lap 8, Rossi lost his foot grip on the outside peg and it went up in the air, but luckily he managed to get back and didn't go down. Similar loss of foot grip happened to another rider just minutes later. In both instances, shake/slide caused it.
 
I have yet to meet a rider who had a good grip on body position who had an issue maintaining that body position throughout a corner. The ball of my foot is always on the footpeg unless the shifter or brake pedal is needed.

If the rear spins up on corner exit, how does the rider react? Yes, he quickly lifts his arse off the seat which is tough to do with the peg in the arch of the foot.

I wouldn't be interested in these things and my guess is not many well schooled riders would be either. :dunno:

Can't teach old farts new tricks. :laugh:
Neither are they willing to try new things. I bet you still have a flip phone. :moon:
