Swing Arm

[Team-Ty]

Well here is Paul's swing arm I made for him. He ran it at maple shade and worked mint weighs 6.6lbs with the carrier and has 14 plus inches of travel (depending where me mounts the shock). Just wondering your thoughts on this

[Team-Ty]

another

[STRAUBMAN]

looks nice whats the price for one gonna be?

[Team-Ty]

I don't have price yet on this, it was a concept that worked very well. Before I went any farther with it I wanted to know if you guys liked it or would be interested in it.

WOW Shawn ( THAT THING IS SICK:eek: ) AGAIN WOW Where did you come from with this amazing stuff your pulling out of your sleeve keep it comming. Do you know MAGIC? Nice Job Shawn is it DS MODZ? Great Job Again!!!!!

[marsrace2]

I need one, and that carrier and that rear axel assembly.

[born2ride14]

I like the adjustbility of it. no other swing arm features that

[jandjracing]

I have seen one out there like that about 8 years ago on a Polaris 50. It did not have the adjustable lower shock mount though. MX riding took its toll on it. Looks good though.

[Team-Ty]

yeah I know the swing arm you are talking about it was mig welded not tig welded plus, the one I had all the welds were starting to crack. Plus where the gussets were, was not the stress points on that one. I will be testing it some more before the final product is done but this is pretty close to final design.

[WOLFPACK]

Very nice! I really hope it test out well! The swingers on the mini's really take a beating.

[skyeryder]

where that angles back to the rear is it above the rear sprocket or below the sprocket. I guess my ?? is could that rail be used as a skid for xc or a piece of flat stock welded on for a skid?

[Team-Ty]

Well yes it could be done. If that was to do bone I would use a thin piece of aluminum that was screwed on. Lets say something like a 1/16" piece of flat aluminum sheet so it wasn't heavy. Then on the bottom of the side rails drill and tap 10-32 holes and bolt the piece on with button head cap screws. This way hear if you hit somehting hard and bend it you could take it off and flaten it back out or if it was real bad just get another piece. Good idea!

[skyeryder]

you get the bugs worked out pm me, I think that would be idea for us as we are gonna race xc and flat track should give him lot's of possible ride heights....

[Reimer Racing]

We ran Zacks quad for the first time last week and had no issues at all with are new swingarm. Like Sean was saying it weighs only 6.6 lbs including the carrier. Combined with the gocart axle and hubs I have really shaved off alot of weight.

I am glad I took the time to polish it and then I had it powder coated clear. It really looks sharp on the quad.

Thanks Sean!!!!!!

Can't wait for my TT swingarm to get finnished. ;)

Here are a couple of more pics.

Very nice!!

[etondaddy]

We were at Mapleshade this past Sunday and had a chance to look at the swing arm close up in Pauls trailer********WOW*********sweet, this sucks we've been out of the CVT's for two years now and they have come out with some really trick stuff that's also functional. When we were in it you were limited to were you could get stuff now people have choices and that drives the price down so Joe the plumber’s kid can race with some trick safe pieces on his or her machine. Great job on the swing arm it's going to be a big seller.

very nice arm and great thinking, i just thought though how long till some one copies it, i have seen a similar thing in the UK but no where near the finished product yet, yours really does look fantastic

[backinsaddle]

great looking piece, lots of great ideas in that design. my only concern would be side-to-side movement...land a jump sideways, bump off a tree, etc. that's pretty beefy aluminum, but i'd still be a bit nervous. every think about some lattice work to join the two sides of the swingarm?

[Team-Ty]

Well there is some. If you look there is 2 3/4" round braces just before the axle carrier that are welded in, up from that there is the shock which is bolted with one bolt straight through holding it together then there is the main pivot tube that is welded and the gussets that are welded on the main tube connecting the side rails. I guess there could be more, but the key thing here is light weight. It will hold up to jumping and take a pretty decent side impact, but there is that one time like always where it may fail, what that is yet I do not know. With any part there is the breaking point, we have not came accross that yet. If your going into a corner throttle on and slam into a tree with the rear tire I would say somethig might happen to it, but nothing is designed to take a hit like that.

[Reimer Racing]

Glad you guys think its sweet. As for landing sideways I think it will be ok it has 2 soild bars welded in and the shock mounting bolt should hold it. Plus 3 gussets in the front. As for a tree depending how fast he is going and how big the tree is. Plus I would bet the axle would bend before the swingarm would. We only MX with this bike no trail riding.

I do know that Sean ran it thru a computer simulater to test the stress it would take to bend it. It will start to bend at 850 pounds. That is with out the shock. Now factor in the shock and and I dont think Zack will ever bend it. Sean is designer / machinest by day and a idea thinking nut at nite. ;)

[raidernut]

aluminum bearing carriers, aluminum swingarms, go cart axles, all this leads up to a very light rear end. But how about the bias in the bike? I know our bike is already nose heavy, without running any aluminum rear components. I would be kind of leary of hitting a big double or something with the *** end of the bike so light. I know that weight bias plays an important role in the handling of these little machines, and i dont know if this direction would help matters any. Just a thought, let me know what you think.

[Team-Ty]

Well now that Paul can answer that one becuase my son doesn't jump high enough yet, but i am working on stuff for the front end. Not going to say to much at this point but about 10lbs off the front I am shooting for with this one idea. It is coming, not as quick as I want but it will be here soon!

[Reimer Racing]

The swingarm that I asked Sean to desin and build was going to be for Zacks Flattrack/TT bike. Where weight matters alot. But then I bought a long travel shock for his MX bike and needed a new swinarm.

Good point Mark I was worried about that also being very front end heavy with the jumping. Rocky and I went back and forth for a week on this issue. I kept saying that Zack is a big kid and his weight would off set the loss of weight in the back. I took a chance and it worked. When Zack is jumping the nose looked just the same as last year.

I asked Zack if he could tell the difference from last year to this year. He said yes the landings are alot softer. He said nothing about landing or taking off differently this year. I did not put it in his "ear" about being frontend heavy because that's all he would have been thinking about and not driving it to the best of his abilty.

All in all I took a chance and it worked. Looks good and shaved off alot of weight. The only thing I would do differnt is not so many adjustment holes but it does give me the ablity to put on a 18inch snowmobile shock. And i would have asked sean to send me the peices before he welded them all up that sanding and polishing s**ked it took me 2 days. But it looks great now

[Team-Ty]

Ok well we are putting some final touches on the design, after playing with it last night again, we lost another 1/2lb and made it 35% stronger in side load force (its not the material that makes it strong its the design). So it is getting there, hopefuuly by next week I will have a couple to test out again. Now I am going to make this in 2 sizes a regular length and a plus 3", let me know if this sounds good to you guys.

Hey Shawn the weight of these are awsome. They are the sweetest swinger Ive ever seen keep up these great products!!!!! DS MODZ :D :D :D

[Dave_DS-MODZ]

Hello everyone. I guess I'd like to introduce myself. I'm Dave, Shawn's partner at DS Modz. I'm the Engineer who has to put up with Shawn's overwhelming amount of ideas for new products and deadlines! I've been working on the swingarm's design and improving it. Our goal is durability and ease of machinability making it more affordable not only for us to make but for the enthusiast looking for an edge over the competition. I personally am confident in the prototype we made for Paul, and I am very enthused to see all the positive feedback! Shawn and I thank you!

I’m new to the mini-quad sport, but I’m no rookie to motorsports. The fundamentals are the same! Shawn’s passion for the sport is contagious! My son is only 15 months… but I think I know what we’ll be doing in the future! Well anyway, that’s my spiel… back to work on the swingarm!

[skyeryder]

welcome to the site, I want the XC version, with skidzzzzz. :D

[Logan #34's Dad]

That thing is real nice. I've got the carrier and I am pleased. It is definately lighter than the stocker. I will have this swingarm next and we'll let Logan jump through the air to check the bias. I'm thinking that he will just have to learn how to position himself on the quad for it to fly right. IMO.
The rolling resistance will be alot lower which should equal better acceleration and more speed. We'll see next weekend at Steel City! Race YA!
You TT guys should gobble this thing up!
Hey Paul, I noticed the video camera on the handle bar. How's it work there?

Although we are saving a substantial amount of weight over stock, it is not enough to see any noticable "flight" characteristics while jumping. The inertia of the rear wheels rotating will correct the pitch of the quad while in the air anyways... the ol' give her gas and bring up the front thing.

If your gut instinct still doesn't agree, you could always buy an extended "lighter" swingarm and move the mass in the rear further back. This will shift the center-of-mass back resolving any undesired weight distribution you may be concerned about when lightening up the rear-end.

I wish that Brad Loomis would chime in on this subject, as he has a lot of knowledge with weight bias on the minis front to rear, as he has tested with his carbon fiber axles. I think that he would agree with my concerns.??

[Team-Ty]

Well Reimer is racing today at Mapleshade again. I will hear from him later today on how things went. I will get a buddies weight system from his outlaw car and put the bike on it and see where it is when there is a 100lb rider on it. Will post the data when we get done testing it. We have done some more changes and hopefuly have somehting done here soon. I have to get the reed spacers finalized. Already made 50 or so and ran out, so have to make more here very soon.

[Team-Ty]

Well it did great again, Reimer took pictures of Zack in the air jumping the bike so would love to see them. He said he would post them on here. Anyways If anyone is going to Steel City, Reimer is racing there. Let me kow what you guys think when you see it close up and on the track.

[Logan #34's Dad]

Hey Shawn, Do you mean Steel City?

[Team-Ty]

Welll yes Steel City. Paul keeps calling it Oil City LOL. Now he has me doing it.

Thats because we are going to Oil City for the EDT. Nat. on June 19 after Steel City MX Nat. ;)

The wifey did take some pics of Zack. Again we had no problems
Zack flys though the air nose up on the landings. I would not change a thing.

Nate the owner of Mcnett Racing was there with a couple of his pro riders testing shocks for Steel City. I had him take a look at are shock setup. He had zack on the practice track hitting some jumps and adjusting the shocks. I asked him if he thought Zack was flying through the air ok or not. He did not seemed think there was a prooblem. After some adjusments and Zack said the bike was landing and going though the woops better than ever.

Great pics Paul...........;) . Mapleshade's a great track Kyle loves it there. We have five more trips scheduled for there I hope we can make them all. See yea at Steel City.


Mike Kozura

[Team-Ty]

Nice Pictures Paul! Looks like he is as level as you'd want! Nice job Zack, will have something else soon for your bike to try out for us.

[Team-Ty]

Paul Reimer called me Sunday and reported that the swing arm worked great again, no problems. Let me know if you seen it at Steel City and your thoughts on it.

[Bowhunter69]

We seen Zacks swing arm in the staging. Looks like a nice piece. I liked the way he painted the letters you engraved in to it. If I ordered on can I have my kids name engraved on it.

[Team-Ty]

Well at this point since I am making them as ordered yes it can be done for now. Name of rider or anything else you can think of as long as its not to long.
