Thanks so much. I wanted a lower rate mono shock coil spring for my 2012 Honda NC700X and there is so little information. Now I just need to figure out the exact or close enough dimensions to pick a rate that is less than 600 lbs / inch of the stock coil. While some people said just by a YSS complete shock - you don't know what the coil spring rate is and you can't order a custom coil. I want to test a coil with a lower spring rate and if I like it I might get a YSS or other shock and then swap the spring.
You're a wise man. Shocks be expensive and the springs (relatively) cheap. Plus, it's not overly difficult to swap out a spring. Good luck on your quest for a better ride and enjoy that NC700X!👍😀
That's a great tutorial, I have watched most of your videos as I am doing a similar build. Thank you for the time and effort to put the information out to the public. Now, looking back at your project, do you think you could have made it work with the stock CBR600 shock? ( I have seen a lot of cafe racers on youtube that have straight on bolted shocks - most of them without rebound or compensation built in the shock). Disregard the shaft clearance..
Good luck with your build! I certainly could have used another shock. Basically any one that I wanted once I realized I could swap out the spring for whatever weight I needed. I also could have spent less time calculating :) as I tried to make the swingarm, etc. to fit the spring rate on the shock - waste of time. It also would of allowed me to use the gas tank w/o cutting it. I still think the linkage was a good idea as it controls wheel travel and stress on the drive shaft joint. Also of note is that it works great. The suspension works great! I think that the linkage contributes to the smooth ride. Are you doing a Goldwing build, or something else?
@@HooptieDoodle Thank you for the quick reply. I am doing a conversion to mono shock. It is a gv650. The difference is that I started to cut & weld without too much thought into the process of rebuilding it(I am new to all of this). At the beginning I thought that it would be simple and almost any strong shock would do it, but now I realized (after watching your videos) that there are also other factors and forces.. I think I need ether a very stiff spring/shock or some kind of linkage that would keep the rear wheel from excess travel. This would be a Sunday morning solo riding kinda bike when complete
Hi. I have a mind to do the same or similar bobber conversion to my ‘84 GW. Did you ultimately keep the CBR 600 f4i rear shock? I noticed the red spring swap to yellow in this video but not sure you kept the same damper unit. Or would you recommend a different rear suspension unit considering you discovered you could have gone without cutting the fuel tank etc? By the way, I am learning so much from watching these build and fabrication videos!!! You’re taking my fears out of the equation. Thank you, thank you, thank you!!!
Great minds think alike! Right? :) Yeah I started with the 4Fi shock, switched to a GSXR shock, cut the gas tank, then realized I could just swap out the spring for a different spring rate and wished I had gone with the 4Fi shock with a different spring. th-cam.com/video/DJWB_tors1g/w-d-xo.html Here is the finished suspension going down the road (super fun!) th-cam.com/video/nU5PXZtt_S0/w-d-xo.html Thanks for the comment, my man! I am very glad to hear that the videos are helping someone :) That's really the reason for sharing them - so that others can see this is not rocket science. For me it just took the willingness to make a mistake and waste some money and time in exchange for lessons learned and the potential to have a functioning bike at the end. You can totally do it! Best of luck!
That shock that you showing, is it mono or regular shock that you converting to mono by swapping to the stronger spring? Just want to figure out if mono shocks are built differently except stronger springs. Thanks for the video!
I used a monoshock off a Suzuki gsxr. I am not a shock engineer and do not know what critical differences there may or may not be between shocks. For this bike I chose a shock off a bike of similar weight to try and ensure adequate engineering for my application.
In theory, yes. That's how it's commonly done on cars. On bikes, it seems more common to make small adjustments via the preload adjuster, swapping out dog bones, or swapping out the entire shock. The geometry of a bike is different than a car, and so there are more considerations. I don't have all the answers, sorry.
I don't have any experience with air ride shocks and don't understand the physics of them, but my broad understanding is that an air ride shock has a variable spring rate depending upon how much air ya pump into it. Don't know if that answers yr question, but I'm also uncertain as to what your question was 😀

Can you also only change the spring to adjust the height of the bike?
In theory, yes. That's how it's commonly done on cars. On bikes, it seems more common to make small adjustments via the preload adjuster, swapping out dog bones, or swapping out the entire shock. The geometry of a bike is different than a car, and so there are more considerations. I don't have all the answers, sorry.
Could an air ride shock work with this set up. My thinking you could adjust the ride with a blue m unit to power it
