Cosentino damping cartridges

Well based on the technical merits, I have placed an order for Chris Consentino's cartridges through NYCnorton.com. Chris is an engineer and knows what he is doing. Kenny Cummings and others race with them. Furthermore, having compression damping in one leg and rebound in the other is truely retro in my not so humble opinion, rather bi polar really. Our race team will be holding a memorial service for this retro concept and will highly recommend the bi polar conversion to our nearest competitors with the sincerest hope that they make the mistake of using them.
If you want true top line fork conversion performance, see Consentino.
I have no horse in this race.
 
Sorry my mistake, Showa are relocating in Thailand...and not china :oops:

All damping works on the resistance /control of compressed oil. i have showa internals with shims under the bench some where,they are quite basic i n the fact the shim simply uncovers a ring of holes.

If that is you interpretation of how a shim stack works you're either displaying an astonishingly low understanding of damper basics for somebody who offers a damper for sale or trying to bad-mouth a competing design. Fine tuning the shim stack gives a huge amount of control of damper characteristics and as I follow Chris' work for quite a few years now I'm sure he's able to exploit that potential very well and has done so.

Plus your "Chinese" comment is simply pathetic. There's actually a Showa damper manufacturing unit about 100 mi south of your place so if you wanted to imply sub-standard third world country quality that backfired slightly.

Thanks for making my decision on what to buy much easier once again, well done on that.

Retro is good! The New Air cooled Norton just fits that...retro! No fancy water cooling for them.
Plus dont forget the push rods :!: Might pop over to donnington and see if i can sell some Reto Lansdowne Damper's to go with their Reto bike :roll: Speaking of engineer's i was building 250 ton power press's 42 years ago. Dont doubt Chris knows what he is doing with forks...before i made dampers for fun..i produced 100 million pound fully robotic assembly plants...before that 20mm cannon for jump jets at the MOD ..now i sit on my laptop reading these posts...my how things have changed!

Would really like to know how yo'all test forks function. In my case its how easy they get me into recovering a hard crash by loss of front itself or the fork rebounds or lack there of, into whole chassis, [ignoring bar grip jarring over rough texture ]. Btw just spoke with a big Ohlin's vendor and they don't know of progressive dampening forks off hand just adjustable, so will have to contact Ohlin's direct for that detail. They also have no reports of downsides of asymmetric components-functions in retrograde designs. I've run into fork twisting delaying pilot action then over reacting as they un twist, in symmetric retro and modern forks, like trying to steer tugging or pushing on rubber bands. Its hard to impossible to feel these separate fork issues in too rigid or too flexy chassis though as tends to over lap with tires to frame to wind eddies feedbacks that confuse what's doing what. There may be a point where there is no difference among fork upgrades evaluations, as other things overwhelm any forks. If Peels power plant works out may have to dig up your Roadholder graves.
 
John - you have given great service to Norton owners with your dampers. They are a SIGNIFICANT improvement over the stock items. I can testify to this, because I bought a pair of Lansdowne dampers. However, you do yourself no service by criticising Cosentino. Comparing the Lansdowne with the Cosentino dampers would be like comparing Hagon shocks with Maxtons. You might pay twice the price for Maxtons but many people will not need a Maxton and are quite content with Hagons. Your market should not be affected. The main diiference is that the Cosentino dampers have so-caled reactive damping while your Lansdownes do not. And you pay more for that. Some customers are happy to pay the extra cost, while others might want a cheaper fork upgrade, which is where you come in.

@John. All good points and your system sounds like a cost effective/competitive improvement to Roadholders.

So rather than sit around the computer and make posts I suggest you get back to work.

As stated above by another, your nitch is certainly not Consentino's nitch......in my opinion.

Never meant to infer or suggest you do not know your stuff.
 
The Dampers i make ,where never intended to be world changing,infact they where designed to "just" be better than the clonky original items.with some adjustment.
I only wanted to produce a few to get my original costs back.
After a few sales to some well respected Norton men,with good feed back i took the plunge and had a few parts CNC made,100 parts was the min cost effective order.
Then Constant at Holland norton Works listed them on their site and fit them as a up-grade..after he rode from Holland to Itaily and back!
I wish Chris {consentino] all the best and i am sorry i got underhand this morning..havig a prostrate problem keeps me up all night..first thing i tend to be a bit "Gun Ho".
I would like to give all the lads on this great forun who have purchased the dampers a big thanks.

John,

A lot of people have made valuable contributions to improving the Norton. You are certainly among them, as is Cosentino. Much like the Ford or Chevy preference.
 
Here's a pretty good fork function test video. Can you spot by vision or ears the things that imply corner cripple. If ya can't, then ponder why its so obvious a fork issue to me. If ya think he's attacking turns, he is, for a corner cripple. At least he's pressing the dangerous green thing to get a few short tire howls and chirps, after the harder part of turns, is behind him. Bet the chassis behavior makes a steering damper nessecary to even do this good.

Cool video. I'd luv a few laps on that track. Except I'm so slow, I'd probably be able to read the graffiti on the ground. I'm kind of a nube, so I'm not sure what corner cripple means.?

Oh yes its scary fast track video to me too, feeling the balloon tires get gooey while shaken on edge. Best camera set up for revealing what's going on. Must be on a gimble on a stalk. But put two or more of these brave pilots and powerful bikes in neck and neck contest and the real issues show up. Certainly hotter handling than vintage seems up to so water cooling needed. Strange but addictive state to get into, going so fast you don't have time to get scared so nothing controlling the throttle but how much more ya can get away with it. When the forks begin to vibrate that's time to either top off the loads or prep for a sudden change of handling behavior. This green thingy video shows typical inline 4 character of fork fight to to stay down, while V-twin tend to fall over but then suddenly fight through forks to get back up in time. I mean we is talking best maxing out devices, not just sane thrills aren't we.
 
My rebuilt fork sucks. I guess I'm used to the Fox suspension on my Santa Cruzs'. Anybody bust for a set of these recently?
 
Just finnished my 356 th set,I am not saying the Lansdowne kit is state of the Art,but ..good enough to up-grade the Basic Roadholder design.
I was given a Challange 4 years ago to produce a system that prevented the famous norton top out clonk.
Local fork restorer "Fitforx ltd" asked if a damper could be designed to get rid of this Knock.
After a few prototypes i made a " Oil tuneable" system, Duncan Fitchett, LANSDOWNE race series tested them, His report can be read on my web www.lansdowne-engineering.com .
The first type was not a great success, so a MK 2 was made.
Based on the modern triumph design REBOUND and COMPRESSION resistance with a adjustment.

Since then 10 Manx racers have found the system "Much better than the originals "

Manx racer as two bikes ,and last year did a head to head on the IOM .

He told me the Lansdowne equiped manx responded much better than the Stock Norton , his words " there's a long straight with a sharp bend at the end, heavy braking
cause's the front end to dive and the forks start to go "all over the place" With the Lansdowne its much better controlled"

Duncan Fitchett 's testimonal , After filling the forks with 140 gear oil .heated on a stove before the race this was the only way to stop the forks from Bottoming out, with johns i simply dial in what i want and get on racing.

Lab and Reggie [forum members] where the first to use them on the road, again their feed back can be read on here.

John Dunn, Nortons tec adviser tried a set..Read his feed back ,again a very happy customer.

Not every one is happy, John Tickle and his two freinds in Belgi where not impressed and a lad in scotland . The first sets where restrictive, But changes have been made since the original design..was that allways the case with early commandos....let the customer do the testing then the factory modified the bikes :lol:

My goal was to make a simple effective Drop in system that is AFFORDABLE....4 out of 350 aint a bade result...Didnt every widow maker frame get recalled :?:
and nealy all combat's .
Not to mention all the other commando quirks.

Not saying the LANSDOWNE kits are all singing stack shimed sytem....But when set up they give good reliable results, after all 10 sucessful racers all carnt be wrong.
Austin Kear, Jack Ebb, Peter Crew, Stu Tonge, Duncan Fitchett, John Jones Mark Parrot, and super bike rider J Mcwilliams ,who set the second fastest lap at goodwood .

Featured in the Norton owners club mag as a great up-grade after a good testing.

Lastly Constant Trossel HOLLAND NORTON WORKS recommends and lists them as a Up grade...in fact as supplied 12 sets to his customers two on order as we speak.

Now please dont think i am looking for more orders...i have enough!

Were they the ones I payed for end of December ? :wink:
 
Paid for in Dec. comment implies some distrust in producer but its only because its such an improvement with such demand you got to get in line to get yours so just cool your jets and let us know later how well worth the wait is. You ain't dealing with the New Norton Inc. but a real man of his word devoted to improving the breed and saving bike and pilots bad ju ju. To make a go of the scale of expanding market means volumes to process. We don't know how long the supply will continues so thank lucky starts is exists for now.

Excellent deduction HoboT but a tad off centre/center. :D

I was thinking given the website says around a three week wait period for the dampers construction (perhaps) plus a week or so for posting they might very well be on their way or very close to being here.
Don't need to wonder any more,the sound of a CT110 postie bike 5 or so minutes back and here they are all the way from the UK.
Set 356 will be for another lucky punter.
