After market springs are always labeled their rate on end of the spring. Stock springs usually don't have any markings. Just FYI.

Thank you! That was what I have been reading and I have the stock VFR springs and they are not labeled :) I will take a look at the ZX10 springs later, after I have finished out the bike.

After looking at your film i went in to my vfr -99. Have original fork and have just given it a total rebuild. Having the bike on the central stand give me about the same travel as you. Take it down and swing a leg over it and measure. Dont have sag numbers in my head but measure max extension by take weight of front then sit on the bike compress a couple of times and sit normal on the bike. The diff here i THINK should be around 35mm..

Will do, thank you👍

It sure looks to me like the fork tubes are bent. Considering how the bike was crashed, it would not be surprising.

Those forks are not original to the bike. Sure they could be bent from some other mc crash, but he would be able to see that for the most part.

For the interim, wind out the preload and see if that gets you any more travel... 👍

Have you considered that there might be too much oil in the forks?
@HooptieDoodle2 күн бұрын
That's a good thought 👍. I plan to delve into these forks and, likely, swap springs and change fluid. Hopefully all that will improve things.

I'm a big guy, carry gear for long distance riding, and use 1.0 spring rate on my VFR original forks. I also ride aggressively in the twisties here in the PNW and like the stiffness they provide. I'm guessing you're around 200-220lbs? and if so, you probably need .95 springs which isn't enough to matter. 200lbs or less and you'll want .90 springs approximately. On a slightly different, yet related matter, you really need to figure out the centerline of those forks and the centerline of the originals in the triple tree to compare how far off they are from one another and do some geometry calculations which I assumed you had already done when getting the forks. You shouldn't have to use shims if that wheel is original to the forks and if your triple tree is making the forks sit narrower or wider than they should be then your forks will be bowed and not compressing and releasing properly. I hope that all makes sense? But the bottom line is to pull the springs first and find out what rate they are which should be marked on one end. Worse case scenario there are spring rate calculators that will get you pretty close depending on your measurements. Once you figure out the rate, you can then make sure your forks are aligned side to side all the way down, from top to bottom and not bowed causing binding.

Some GREAT recommendations - thank you. I will pull the springs and see what we got. I can determine the centerline of my current setup with the ZX10 forks in the CBR triple clamps, but I don't have the ZX10 clamps to compare to, so I can't get that spec here. I will try to find it on the internet somewhere. Great idea>

@@HooptieDoodle as Naptownstreetsquid mentioned below, stock fork springs may not have the rates marked on the end, but it's easy enough to do research and find out what rate they put in the forks, either through a G search or that particular fork (bike's) forum. Oh, and I forgot to mention that you weren't getting much travel in this video because the bike was on the centerstand and really needs to come off it in order to get your sag measurements correct. I'm making the assumption that based on your initial ride you just thought they were too stiff, which they very well could be for any number of reasons. Lots to consider but I'm sure you'll figure it all out.

Reducing the surface friction of the disc from the entire wheel hub to small washers is a VERY bad idea. The bolts are not designed to endure the sheering force involved in hard braking... Very dangerous and i suggest you take down this video of make a disclaimer next time...
