Search Results (Searched for: ZRX shocks)
wade.long@dominoeffect2.com
So my let me tell you a story (and it's not about "Bertha Butt"). I am going to post this on some of the motorcycle forums I am a member of, as quite a lot of the time, I see many more suppliers affixed with the dog eye for maybe not the greatest quality parts or service, while there don't seem to be as many props given on the good side.
This has to do with Hagon Shocks based in the UK. Full disclosure, I have purchased 5 sets of shocks from them, dating back ~15 years to a monoshock for an '88 FZ750 my son and I were restoring, a 2003 ZRX1200R, aso.
I originally ordered some standard Road-series shocks for my KZ1000A1 build, but as time progressed, I decided the build deserved an upgrade to the 2820 series that have adjustable dampening (Road-series are for sale on EB for a decent price...or make me an offer).
Received the 2820's...two problems: 1) From talking with Hagon sales & tech peeps (great people), one of the shocks had a defective dampening adjuster, it was only supposed to rotate ~3.25 turns lock-to-lock, and this one rotated 5+ turns.
The second issue was that the 2820 design is kinda upside-down, in that the spring is down low on the shock, with the unsprung length on the top. This in itself created an interference with the chain guard on the left side, pushing it into contact with the chain. And these shocks were the recommended p/n’s from their ordering spec pages.
Long story short, Hagon sent me a new set of 2820 shocks gratis, and these were built in a "custom" style that they had done previously in some cases i.e. the non-spring area was on the bottom, with the adjuster on top, and they fit perfectly. Prior to deciding to do this, the person that was helping me at Hagon (Dave D.) sent me a photo of the custom 2820 style installed on an H2 (he also owns an H2...cool!).
So that's it, just a little shock saga and props for a suspension company that stands behind their product and application specs. Cheers.

Using nylon spark plug dividers and M4 rivet nuts to make a neat brake line and throttle cable guide for the neck of the frame.
Last touch, the custom Bitubo decals for the shocks that Dennis (Kazman) made for me back in 2016!
That is it for now.....

Cory, did you have to modify anything on the frame or swingarm to install the shocks? I too have a ZRX swap going on. Thanks for any info

I have finally got the ZRX swingarm installed in the 78' frame. It looks like the shocks will be at a bit of an inward position. Does any one that has done this have any info they can offer? Thanks

Or you can try Race Tech.

Looks like they do Ohlin shock and many others, so try give them a call or email?
Not for my KZ, but I did have them rebuild my 89 ZX-7 shock. Actually, it was for FZR (forgot which model) NOS unit I scored cheap and send it to them for rebuild. Before sending the shock, you need to fill in the spec sheet, such as your weight and what the use for (like street or race) and they rebuilded accordingly. I now have really nice shock. Stock ZX-7 shock is too stiff and bouncing all over the place. I'm still in the process of putting the bike together so no ride report yet, but just sitting on the bike can tell the difference.
After I get the KZ back on the road, I'm sending them my ZRX shocks to have them rebuild it.

Well, here we are in January 2024. Where have all the years gone . . . Over Xmas, I decided to upgrade my PC from Linux Mint 20.3 to Mint 21.3. and as I prefer to do a clean install, rather than an incremental upgrade, I wiped the HDD and started from scratch.
After the operating system was loaded, I restored my recent back-up files, and during that process I came across an old CD with some really old files on it, including an old password file I had quiet forgotten about. And, guess what, it would seem that my KZR user-id and password still works.
A lot has happened since my last visit 19 years ago. A lot of the old members I knew way back seem to have "disappeared", although I do see some that some are still active, and it is especially pleasing to see that a "new" KZR generation is picking up where the old guard has left off.
I sold my ZRX1200 about 4 years ago with about 150,000 km on the clock. It was a fantastic bike and never let me down, but it was probably in need of a complete strip down and re-build, which the gentleman I sold it to proceeded to do. A 1224 over-bore, ZZR cams, a 6 speed transmission and USD forks gave it a new lease on life. It already had a full Akrapovic exhaust, larger CVK 40mm carbs and reworked rear shocks.
I sold my KZ650 about 2 years ago because I very rarely rode it anymore and a friend wanted a "classic" to ride to the coffee shop every Sunday.
In their places, I bought a new 2019 Ninja 1000 SX, which now has about 25,000 km. No more carbs, or points, or marginal brakes or . . . .
But just like my KZ650 and ZRX, I could not leave the N1K "stock". It now also has a full Akrapovi exhaust, and custom ECU tune, RaceTech forks and rear shock, revised steering geometry and a few cosmetic changes. Unfortunately, the 2019 N1K did not come in green, so it is a stealthy gross black.
Good luck to the new generation of KZR members, the KZ, in its various forms, is a great platform to work on.

Finally took a longer drive today after reinstalling the head with a new gasket and viton o-ring. Did as Gamma adviced and used RTV to keep it in place. It is sealing now, what a relief!
I had to adjust the pilot screw after the first test run, from 2,75 out to 3 out (I also did 2,5 as I first tought it was an air screw, but the idle got really upset
). At 3 it is pretty good, but I need to do some more adjustments when I do the vacuum syncing. Also ordered new clamps and plugs for the carb to insure its not leaking.
It was quite nice riding, pulls strong and pretty quiet from the camchain and valves department. It did have some issues. At 5-6k rpm it stutters before it continues to rev. I think this is because in an attempt last year (before tear down) to rule out pinging, I raised the main needles. I will revert that. One of the cam caps is also leaking pretty badly and one a little. I read someone here advicing that you can pull them down with a fastener after you apply RTV to get them to seal. Will try that!
I also bought new shocks, I went for YSS ZRX 1100/1200 shocks as they are bolt on but 360 mm instead of the standard around 350 mm. The old Girling copies where 335 mm and I could not use the center stand without risking of dropping it. The travel lenght increased alot and I like the look with more air between the tire and rear frame:

To re-launch BOTM we are starting with a heavily modified 650/1170 from Lee (Bevelhead) in the UK. The intention is to use BOTM to showcase the passion and hard work of our members in their quest to preserve KHI’s finest from the “glory days”. With this in mind I am looking to feature a mix of modified/stock/restored and survivor bikes of the era, if it “has a story” drop me a line. I don’t intend this to be a haven only for mega buck show winners (although they are also welcome) I want BOTM to inspire other members around the world to get out in the garage and smother their rides in love and attention.
The project started with a badly 'bobbed' 1978 Z650 frame, GPz1100B1 engine cases, Z1000 tank, and not much else. The project belonged to a good friend, who'd already cut the rear part of the frame to widen it to accommodate a wider modern rear wheel and tyre, without the need for spacers on the shock top mount. The frame has now been braced to cope with the extra power and now uses a 20mm swingarm spindle.<br />Since the frame had been widened, a standard seat and ducktail would not fit, therefore a new seat base had to be made in fibreglass and the tail piece widened. The seat then went to specialist upholsterer who did a good job, except he'd got front and back mixed up!! the assumption was made (don’t ever do that) that it was obvious which was the front and which the back, but apparently not.<br /> Bodywork is early Z1, but the tank is from a Z1000. Paint is similar to OE, but with a few changes. For example the upper tank stripe is dark mica blue, not black, to match the blue of the front callipers. The plan originally was to fit a cockpit fairing, but the BMW R90S fairing that was purchased didn't look quite right, so wasn't used. Lee has a “Z900RS café” fairing on his Z1000A1 build which would look much better on the 1170.. perhaps something for the future.<br />The rear sets were made long before the engine was ready, and turned out to be too low, so Lee had to make new mounts to raise the pegs and clear the exhaust. The latter is a Delkevic, whose 4 into 1 collector had to be cut and widened to clear the now wider back end of the bike. Since it had to be cut, Lee also altered the silencer to a jauntier angle.<br />The front end consists of forks and brakes from a 2001 Yamaha R6, in one off billet yokes. The back end uses ZRX 1200 swing arm, Brembo rear calliper on a one-off mount, along with K-Tech shocks built for the bike by the factory. Wheels are also one off split rims, made for Lee’s old drag bike by a friend (the one who sold Lee the project).<br />The engine was taken out to 1170 cc using Wossner forged pistons, the crank has been balanced and welded, while carbs are Mikuni RS34s. Clutch and points cover are home made, as are the rear sets.. levers pivot on roller bearings, hydraulic clutch conversion, and an gearbox output sprocket outrigger. The latter has been causing Lee problems as it has an oil leak, but then he had to use a “home-made” gasket, and that could be the problem.. Lee is still working on that. That's why in some pics the chain has been removed, as Lee was working on the outrigger inner plate at the time.<br />Wiring is done by Lee using a “Moto-Gadget M-Unit” which helps simplify the wiring, along with their matching switchgear. Ignition is Dyna S with Dyna coils. It has an electronic Daytona Velona combined tacho/speedo gauge. <br />Brake and clutch master cylinders are by a UK company HEL, as are the brake lines.<br /><br />Once the outrigger oil leak is fixed and the engine is run in, Lee will take it to a dyno and have the carbs dialled in, but it was snowing at the time of writing, so that will have to wait until the spring.<br />The build was without doubt the most frustrating Lee has done, as there were countless problems, while Covid lockdown didn't help. The engine case was found to be cracked, after they had been ceramically coated at great expense. Thankfully they were repairable.<br />

That’s a beautiful job to where the zrx shocks look out of place.
Who would leave such a bike in the weather?

I was tempted to buy a 2022 Z650rs.
RS are my initials.
There is 22 years between my 1978 KZ650 and 2000 ZRX, so another 22 years would be a 2022 model.
The lack of twin shocks, and no adjustable suspension and being a twin engine turned me off.
The z900rs has adjustable suspension and a 4 cylinder that appeals to me.
