 It would be cheap to build, seems viable, and doesn't adversely affect ground clearance..... Any thoughts? | ||
| Malott442 |
This one is more tucked, but I need to find out the spring rate of a stock tuber shock and come up with a shackle ratio and matching shock from another OEM.......  | ||
| Smoke |
search hyperpro or wilbur's shock here on Badweb. both have had a push shock setup for the tubers. tim | ||
| Spiderman |
you missed that train by a decade fellas  | ||
| Jos51700 |
John Britten beat 'em all to that one. | ||
| Malott442 |
No, I dodged that 1200 dollar train. I feel that 1200 bucks is a ridiculous price. I can match up a nice used shock on ebay for less than 100 bucks, and spend less than 100 in heim joints, links, and a little trial and error........ Maybe I'm trying to start my own train. or at least a trolley! haha | ||
| Texastechx1 |
Thats the spirit! | ||
| Thejuicer |
agree 1200.00 is a &%$#load of cash for a shock...cant be worth it...ill prolly save some cash and put an aftermarket one on my X1 this summer...Josh. | ||
| Jstfrfun |
Yea it's do-able, but why? | ||
| Malott442 |
Because.... a good penske is too damn much... Good used shocks, are becoming a rarity... I agree, on the principle, that, a more universal UJM shock would be a cheaper, avenue, along with spring selection, etc... Imagine, an Ohlins rear shock... I know where he is coming from on this, and, I will attempt to put this into a viable solution... Short term benefit.... who knows... long term....... who knows... This IS Chase, posting form Matt's comp, at some resort in the mountains(we are getting drunk, and getting our women drunk)... while drinking my last official night in the Navy... my 10 years ends at midnight... | ||

With a re-buildable version of any pull style shock why would you want to put all that hardware under your already low center rocket? I just don't see the benefit unless you change the geometry completely. | ||
| Malott442 |
That's exactly the thought. By changing the geometry of the link (rear shackle with 3 holes) The stiffness and rate can be modified, as well as the rate slope. You could change a track bike over to a street bike in 5 minutes with a simple shackle change.......... | ||
| Jstfrfun |
Shure but your average guy wouldn't have any use for such a thing. The availability of other shocks and versatility in that respect I can see, but those of us who run frfun, can't or shouldn't need a system like that. I'll never put my precious on the track, but it's a hoot to ride frfun. BTW it ran on the dyno @90hp last saturday, with a rich condition in the 35-5000 rpm range then @ 6000rpm it went lean so I'll have to do some tuning in the fuel map. | ||
| Malott442 |
It wouldn't just be for track. Imagine a link replacing a spring changeout..... Yeah! Riding passenger? No problem. Lowering it? No problem. Going from a 150 rider to a 300 rider? NO PROBLEM> The rear linkages are where the magic will occur. The first linkage controls ride height. The swivel linkage controls spring overall rate. Madness you say? Rubbish! It'll work, I know it in my heart. Also, the weight is not going to be a major issue. It will be less than 2 pounds of heft added. I did some exhaustive research, and the perfect shock was sitting in my Triumph the whole time! It is only 14" long, it has a spring rate of 13.6kg/mm (s1 is 9.8) and the OD is almost 1/2" less than showa. Plus the eyebolt mounts aren't fat. Now, I am rigging up some scrap steel today to begin the experiments! Laugh all you want, skeptics, if this works I will save tons and other people tons. I've been doing trig all morning trying to get the link length, angle for ramp up, and overall angle just right for a very aggressive yet stable geometry./.... Will update with pictures....

Im a believer, if you can do it i want to see. push type shock are way more common and lots more choices are out there for them. | ||

Surprised this hasn't been posted up yet... http://badweatherbikers.com/buell/messages/47623/349877.html?1207504837 Looking at the ready-made kits, I gotta say, "Like I said, Britten got there first:"  | ||
| Malott442 |
Where are his kits? UMMMMM, I'm not trying to be original. I'm trying to stick it to the corps. that make huge amounts of money by exploiting the talents and hard work of underpaid employees. I only buy what I can't build. And Britten's design would not work with an existing tube frame in my opinion because of the additional stresses that would be introduced that were not taken into the factor of the original design. Not to mention the increased weight of the swingarm assembly (slower reactions from shock) and blockage of the exhaust. | ||
| Malott442 |
BTW for the people not aiming negative energies, the first two links are done, now working on the swivel link. Will be operational tomorrow, ugly, but operational. | ||

post pics asap! | ||

Don't let anyone rain on your parade. Just cause someone made one already doesn't mean you can't improve the design. If nothing else, its a good experience.Part of what makes Buells special is that they are different from everything else out there. | ||
| Buellsrule |
Go for it Matt. I'll try one on mine. Frank. | ||
| Jos51700 |
For the record, I'm not trying to rain on anyone's parade. Sorry if that's the case. | ||
| Malott442 |
right on. Well, nature is literally raining my parade today, with a mixture of sleet and snow here and there. I pulled the shock out of the Triumph, and am soon to go outside and pull the X1 shock and mount up the experiment. I now have reconfigured my setup to be stronger, more compact, and less strain on the existing hardware. The front shock mount has to be reworked, but the swingarm mount remains unmolested. I took pictures, but the lighting is horrible. Maybe the sun will shine tomorrow. | ||

 1. Swingarm mount. OEM 2. Swingarm linkage. Round solid steel, Heim joints. Solid steel is replaceable with different links to alter overall ride height. Will not affect overall geometry of shock in any way. But keep in mind that swingarm geometry changes with ride height slightly. 3. Pivot linkages. Round solid steel, heim joints. Replaceable to accomadate different length shocks. Also adjustable in miniature amounts to alter ramp up of shock for style of riding. 4. Swivel linkage. Solid flat steel. Replaceable for adjustment of spring rate. Miniature adjustments cause drastic changes in spring rate, so if making your own, be PRECISE in holes drilled.  Rough draft of how it will sit underneath. Ride height loss will be less than an inch with aftermarket exhaust (front mount) Stock exhaust ride height will be unchanged. | ||

 Its right at 14.75 eye to eye, looks so much better than that ugly space can. BTW it is a Showa unit as well.  SUCESS! I used it at a 1:1 ratio for a starting point.... and the angle was close to 90. I tell you what, you do NOT want a 13.6 kg/mm shock under a buell!!! It is STIFF! Of course with the final design, I will be able to adjust the angle as well as replace the ratio with a new pivot.... I'm starting to feel really excited! Well, now that I've got that unpleasantry out of the way, its time to do some further measuring, as well as some ordering and a little more thinking. I'm starting to think that aluminum can be used for some of the parts. Safety first, of course. If sunshine permits, will attempt a video tomorrow of the magic........ | ||
| Malott442 |
Oh yeah, I did have to run it upside down for this test, because the front shock mount remains unchanged. I am going to have to lengthen the front mount by 1 to 2 inches to make clearance around the engine to tuck the shock upwards. And yes, this is all scrap steel, so give me a break on the aesthetics.! | ||
| Buellsrule |
Hey Matt, I'm getting excited! Go for it! Frank. | ||
| Thejuicer |
Keep us posted Matt...great job already!!! | ||
| Phelan |
Very nice Matt. I'll be looking to do a similar piece soon thanks to your research. I hope you don't mind... My shock is a giant pogo stick and I don't feel like getting anutha stocker. | ||
| Malott442 |
If you don't want to do it, I'll probably end up jigging up about 10 of these and selling them off for a small labor profit.... Can't say how much it would cost right now due to material considerations, but I plan on getting these done and out the door for less than 300 including the rear shock..... Plus I will try to include a spare set of links to change the rate from soft to firm and a lowering link just so everyone can know how cool it feels to sit low on a hooligan. Plus drag racing on a lowered unit is WAY easier. Who knows, I might even re-introduce my lowering link for a tuber that I produced two years ago, for anyone that remembered. A shockingly low number of people actually ordered them (2) and they loved em. Didn't actually sell any here, they were locals in Va Bch. They actually saw the link up close, and I think they got jealous of the fact I could drop the clutch at 3k from a redlight with no wheelie. Made for a wicked fast bike. I only sold em for 25 bucks. |
