Okay, would appreciate a sanity check...
Short version... 190lb rider, 07/08 shock and adapter, max preload, 40mm of sag. Is this what I should expect, or did I screw something up?

They're coming to take me away . . .

I suspect that you and your machine geared up are a bit over the 190# rear loading. 40mm (1.6") is a bit on the high side for preload for the '07-08 spring.

It is possible that you have an '04-'06 spring. If your wet weight is near the 220# range you may need a heavier spring. Maybe not.

I suggest that you put at least 150 miles on the shock and adjust the damping settings for your riding style. Does it bottom frequently? On large bumps or hard cornering? The damping settings should eliminate the pogo-stick effect.

Unless you have some dirt-bike or track time, it is difficult to appreciate a spring matched to your weight. The bike should feel like it is 'floating' over bumps and pavement perturbations. The stock spring is quite stiff and transmits most of the amplitude directly to the riders bum if he/she is less than 240 or so.

Sanity is relative. In this group, it's not shocking to question the norm. Let your butt be the measure. Style is everything, some like it stiffer.

Satan666 - Tried to PM you man but it wont let me? How do I tell what year R1 shock I have? Also your adapter - how much higher does it rains the rear 1/4 an inch (I thought)

I lowered the front 3/4 of an inch, and also have a 1in lowering link, which I believe puts it about right with your adapter, thanks!

I assume that you have either an '04-'06 or an '07-'08 shock using the Version 4 adapter (does not use the upper R1 shock clevis).

The 04-06 shock adjusts the compression from the right side when installed. The '07-'08 has 2 compression adjusters (inner key and outer nut) on the left side.

The Version 4 adapter raises the rear approximately 20mm or 3/4" over stock with proper preload set (28-30mm 1 1/4 - 1 3/8"). Check the lowering link for clearance with the lower shock eye with the shock fully extended. Carefully lift the rear end with a ceiling hoist on the tail section or a jack under the exhaust toward the rear of thee engine.

If your lowering link (dogbone) makes contact with the shock, it is a dangerous condition. The lowering link should have a cut-out or relief at that point to prevent contact. Repeated contact while riding could result in the link breaking, the rear end collapsing and a broken link making contact with the ground. If this occurs while turning, you will have difficulty avoiding a crash.

I assume you wish to lower the seat level. Your approach is fine but may require adjustment (shortening) of the kickstand. Also, with the reduced ground clearance under the engine, negotiating curbs may be tricky with the exhaust making contact.

The FZ1 does benefit from raising the rear in relation to the front with a difference from 3/4 to 1". It gives the bike a quicker turn-in and reduces the amount of force required to counter-steer. Too much difference >1" may result in high speed instability and require a steering damper.

Satan666 - I've got a '04-'06 R1 shock coming. I weigh 175# all geared up, so going from older posts on this thread the '04-'06 should be right on the money. How important is it to get this shock freshened up before I install it? It seems like some people on here swear by having them gone over by a shock specialist. Is this necessary, in your opinion? Or can I just throw the used shock on, not worry about it, and have good results? Also, when I have a passenger am I going to need to crank the preload up? Is this easy to do? I bought my '09 used and it didn't come with the preload adjustment tool, so I guess I'd need to get one of those.

I PM'd you about getting on the notification list for your next batch of adapters but didn't get a reply, so I don't know if it went through.

Thanks

Followup on this, got another R1 shock cheap, measured the same, took bike to local suspension guru, and it was in the 30's with a a few preload steps left... So, either my process for measuring sag was off, or my assistant measured wrong...

I have purchased many used R1 shocks. All of them were clean and did not show signs of leakage. After removing the spring, I check the damping action. So far, I have not received a shock which needs a rebuild.

You should adjust preload for passenger transport. Remember that the GCW of the FZ1 is only a bit over 400#s with the stock spring which is significantly stronger than the R1. Even with preload adjustment you may experience bottoming and you should reduce cornering speeds to prevent that in turns.

Preload adjustment tools are common and available at places such as Cycle Gear. Before you install the R1 shock you should check the rotation collar for cleanliness and lubrication. The best would be removal of the spring. cleaning and greasing the collar and stay insert. At minimum, a dose of penetrating chain lubricant and light greasing of the ramp notches will make the adjustment job a lot easier.

You are on the list.Sorry, I must have missed the PM reply. Sent you the info.

Hey, thanks for the info, Satan666. The shock looked like it was in pretty good condition in the pics, so hopefully it proves to be in good condition when it's in my hands. No problem on the PM reply, thanks again.

Adapter=perfect, R1 shock not so much

Hi Richard, I installed your adapter no problem. Very impressive tolerances on the machining, everything fit just right.

However, measuring the sag I get 50mm with the preload set to maximum. Sag is measured axle to frame from back wheel off the ground, fully extended shock position to position with myself all geared up on the bike, right? My free sag, just bike weight is 14mm. I got an '04-'06 shock and cleaned and greased it like you suggested. I'm wondering if someone put a lower stiffness spring on that shock. I rode my favorite bumpy back road to try it out and the settings are currently: two steps down from max preload, 13 clicks counterclockwise from full in on rebound, 7 clicks clockwise from full out on compression. It feels better in bumpy corners and more stable than the stock shock did, but I guess I expected it to be vastly different. I'm sure my front suspension could use adjusting as well, maybe that would make it handle better. Anyway, let me know if I'm missing something. Thanks

Down the road

First, just finished the production run, adapters are available, glad to hear they fit well. I always worry about the 2 french men (Toulouse and Tootite).

Preload is the measurement between static and loaded sag. Backlashphoenix1 is fairly close to the desired numbers (25-30) with 36mm (50mm loaded-14mm unloaded). While it is possible that the R1 spring has lost some of it's resilience, it is not likely the change has been significant.

Be aware that there is no one mod that transforms the FZ1 with vastly different characteristics, unless you do something really extreme. Replacing the rear shock with a 2x4 would qualify. The rear shock assembly has 2 major purposes, 1.) holding up the rear end and 2.) preventing the rear end from bouncing up & down, separating the rear wheel from the pavement.

The strength of the rear spring is matched to the loaded weight. The designing engineer(s) must select a number which they believe will be best for the target market of the motorcycle. Furthermore, the spring/shock assembly itself must cost the least amount to contribute to profit based upon the market value. In simple terms, less expensive bikes get less expensive shocks. The 'bottom' line, the spring strength (front & rear) must be matched to the individual rider and accessory loading. The shock must be able to accommodate the riding style.

In the case of the FZ1, the GEN II was designed to address a slightly different sport market than the GEN I, just as the FZ10 ups the ante from the GEN II. The spring rate on the original (2006) GEN II was very high likely emphasizing the market thought to carry a passenger and additional gear giving the bike a tacit touring capability. Feedback dictated a change in 2007 to lighten things up a bit. The stock shock has adjustment only on rebound likely because of the heavy spring and mostly to keep the cost down. The nonadjustable compression level is high to match the spring rate. The FZ1 was never intended to be 'exotic'.

Characteristics of a heavy spring for the load manifests in several ways. Small pavement irregularities (tar strips) are transmitted immediately to the seat. Medium irregularities (separations and potholes) are felt first on the rise then again when the rear wheel comes back into contact with the ground. High speed turns with irregularities cause the rear end to wander and kick out requiring steering correction. The lack of compression damping and insufficient (or too much) rebound damping exacerbates the effect.

Anybody who has ridden a stock GEN II can attest to those observations, even zaftig riders who match the spring strength experience the wallow effect.

Too light/weak a spring causes a dip effect over larger irregularities and potential bottoming on high speed terms. When the shock bottoms on the buffer, the effective spring strength skyrockets.

The 2004-2006 R1 spring is best for riders less than the 190# range. This does not take into account loading from gear on the rear end or even a tank bag. Needless to say, a passenger will make a major difference.

The R1 shock is very much better than the stock FZ1. The feeling in one's maximus should be noticeable after 20-30 minutes when it comes to the pounding from small to medium irregularities. I'm not saying that it turns the FZ1 into a FJR (or any other bike with adjustable spring rate), but it does make a difference. It will not eliminate discomfort from other factors such as the seat or bend of the knees.

A major difference should be noticed in high speed turns; however, put some miles on the shock before you attempt to drag things. Tuning the suspension takes feedback, especially since the original had only one octave. Making changes to the motorcycle does not make you a better rider. That takes information, approach and practice. If you are a street rider, better equates to control and a properly tuned rear end helps.

Finally, the R1 shock swap is an improvement solution based in economics. It is one tweak in the bigger scheme of things. Front suspension, tires, riding position, etc. all play a role in what you feel as you motor along, riding in your own particular zone. The FZ1 rider is a bit different than most riders as they/we are willing to actually take a wrench to the machine and change it a bit (or a lot). If you are going to ride at the extremes (over 8/10ths) then I suggest you invest a great deal more.

Thankfully, if you desire to experiment a bit further, you will not have mortgage the house. I suggest that after several hundred more miles you believe the spring is too soft, acquire a 2007-2008 shock ($50-$75), swap it out, ride it and see if you can tell the difference. I am right on the weight cusp and do it on a regular basis. So far, either vintage works well and I find it difficult to discern any difference.

Finally installed a 2008 R1 shock!!!

Initial Impression (50 miles to work, mainly highway):

Soaks up bumps and my bum appreciates it. Didn't notice the height change and I'm short at 5'6". I like it. Thank you Satan for these adapters.

Just installed mine today with the V4 adapter. Haven't been able to go on a ride yet so can't review the shock but the adapter was spot on. One of the bolts didn't want to push through it, but turning the bolt as if the adapter has threads worked. Used a textbook to hold the rear wheel up. I was afraid the rear wheel would be too heavy to move up and down but on the contrary, it was super light.
