Best explanation of suspension I've heard. You deserve a university teaching position.
I think for a part two of this video it would be interesting to show what some adjustments to the suspension do to the behavior of the bike. And what kind of changes you have to make to the suspension to solve some common problems experienced during racing.
Check out Dave Moss Tuning
mrSabic yeah I know him, it’s a paid account tho..
I agree, that's a great suggestion and a video I'd def watch
Now I understand what other 100 people were trying to explain me. Grazie!!!
Excellent video, but I have to correct you on one thing said @ 19:20. The total K value for 2 springs in parallel (side by side) is the sum of both K values, NOT the average of the two. If spring #1 has a k = 95, and spring #2 has a k = 100, the K_equivalent will be 195.
I can derive it for proof:
Spring 1 and Spring 2 are in parallel, so they will both be compressed the same distance x when a force is applied.
So the total force is F_total = F_1 + F_2
Recall for springs, the Force = k(x); (k value times distance x)
So we can substitute original F_total equation and say, F_total = k_1(x) + k_2(x); (remember distance compressed is the same x since they're parallel springs)
Factor out the x distance, we have:
F_total = (k_1 + k_2)(x)
Therefore, with the equation above, we can conclude that equivalent or total spring constant k for parallel springs is k_1 + k_2 = k_total
I remember you mentioned that you would of liked to be an engineer if you didn't choose racing in a past video, so thought you might of enjoyed this!
Cheers from California.
Yeah this was definitely the best suspension video I've seen. I watched a handful today and all the others started just rambling on about things that experienced folks would know, rather than INTRODUCING the concepts, despite the videos saying "all you need to know", "101", and "explained." Thank you very much!
You explain this better in english than anyone so far.... thank you so much.
Very informative video Naskaa👍
But I would like to say today that whole world stands with Italy in fight against Covid 2019😊Stay safe
Decisamente meglio della maggior parte dei professori che ho incontrato fin'ora a Ingegneria Meccanica...
genius engineering to have the wheel rotating together with the brake calipers
Using the rubber balloon and arm is a superb simple example. Never thought of this example.
Even for somewhat sportive road riding the suspension makes a lot of difference, at least in confidence. My bike as undersprung for my weight and riding style, and without knowing it the rear shock was damaged internally.
After having these issues fixed I found myself making naughty kneedowns on some of my favourite roads (which I only did on track before (and is probably smarter to only to there)).
Changes made: replacement rear shock with stronger spring. Stronger springs in front fork, adjusted compression shims.
Costs: ~100 euros for the rear spring, ~250 euros for the front end work.
(replacement shock under warranty)
Difference in confidence/joy: priceless.
Invest in your suspension before getting all kinds of louder exhausts (in fact, just don't do this...) and other shiny accessories.
Your English is BETTER, than many English only speaking people I know. So long!
Great job explaining the principles of this complicated topic. Thank you!
Fantastico Naska, Alcuni insegnati potrebbero imparare da te. Ti prego continua a fare video spettacolari come questo.
As usual, fantastic explanation Alberto. Lots of love from India.
This was really, really helpful. It would be nice if you mentioned something about how different setup changes affect the bike when commuting/racing. But understanding how the parts themselves work was really interesting. Thanks!!
The BEST AND MOST IN-DEPTH LOOK AT HOW SUSPENSIONS WORK I HAVE SEEN IN 30 YEARS....:)
Thank you for this. I learned a lot from this video. Now it will be interesting about the application when adjusting the compression and rebound on the motorbike.
One of my favorite UA-camrs at present. I'm learning so much from you, as you learn. It's such a benefit to so many who watch your videos, keep it up mate 💪😉
Thank you Naska for this video! It was excellent!
Absolutely fantastic video thanks so much.!!!
Great video. Thanks for the info. And, "bottoms out" is what everyone I know says...
Thank you for this video, I needed it for a project for my high school auto class and it really provided good information and was really helpful.
Thank you Alberto. I've just discovered you as I await my Andreani Misono Evo kit for my 2002 900ss ie. It is a very deep rabbit hole is motorcycle chassis dynamics, but your explanations are brilliant. Very generous of you to take the time to make these instructional vids and in your second language. Loved your Andreani factory tour by the way. Kid in a candy shop place indeed! Good luck with your racing.
Thanks Alberto.. great & very clear explanation on how suspension works 👍👌
That was the most educational video of a super-complicated topic (for us:). Niska, I LOVE your videos man. You pick the best topics too!
Brilliant! I had an idea this was going to be over my head... you did a wonderful job letting me know how correct I was!🤣
Thank you my brother... you did great.
Brilliant explanation, thanks!
You make it easy for me to understand a quite complicated subject.
Love your videos. I always learn a lot. Thanks for doing them.
Hi, that's brilliant. The explanation of the suspension was excellent and that is more than enough. Thank you
Naska, thanks for explaining how the suspension and shock absorbers work. Like all your videos you do an excellent job sharing your knowledge and make my motorcycling more fun. grazie
Great Video. Thank you. The quality of your channel has already been good but now it has become really great.
Hey Alberto, Excellent video! I 3d modeling & diagrams of the various suspension components combined with your photos of the actual physical components was very helpful, but the high quality digital simulations you used to help identify and explain the different components that a modern suspension system is made up of, how they function when in use and the effect that they can have on the performance and handling characteristics of a motorcycle were awesome!! All of the visual aids, combined with you're great explanations of all of the different parts of the system; their features, characteristics and even how to adjust them, def makes this one of the best mc suspension videos I've seen yet!! Thank you👍👍
Great Job & best of luck to you this season!!!🙌
Btw, I'd also be interested in seeing a part 2 as Elmer suggested.
Very clear explanation brother. Thanks you.
nice and easy...great explainasion
That was a really good video. It really helped to understand how the needles and discs worked and how the rebound and compression damping can be adjust differently.
Best explanation ever.Thanks Albero awesome vid.
i love how you explain it well . Your number no. FAN from Philippines!!!♥
very good explanation of this complex theme
Very good video and I let to say you'are daring, trying to explained a so difficult subject!!!!
Congrats!!!!
Thank you very much my friend .
I love your videos, one of the best suspension videos i have seen
Excellent explanation, thanks buddy
Thanks a lot bro for the videos you have posted! Very informative! Thanks for always sharing your knowledge!!
this is slowly becoming my favourite youtube channel. keep it up
Very good explanation! Now i understand a little bit better how it works, thx for that Alberto! ✌️👍
Thanks very much
Very, very good information. Looking forward to seeing the part 2 which is adjusting rebound and compression. Cheers 🍻
Great explanation, thanks. 👍👍
That's great information, thank-you
Brilliant!!Thanks man!
Bravo! Nice informative video with good visuals 👍🏽
Very useful info, thank u.
Thanks Alberto ! Excellent explanation. Your video made things clear :-)
Superb explanation!
I clearly understood about the suspension was very useful
This video is the best thing i've watched so far in 2020
I'm already familiar with bike suspension, but i have to say you have made an excellent video here - i will be sending it to some of my nebie friends. Get video, and great explanations and graphics. Much appreciated.
Great job amigo. Very interesting! Thanks.
Interesting and very informative! Always great content☺️ keep it up
You are a university of racing mechanics ... Your explanations make everything so simple to understand .. feel blessed to have subscribed here ..thnxx a lot 👍
Great explanation!
Love the video Alberto think I'll have to watch it a few times to really have it :D thanks Love your content
Former AFM, CCS, WHERRA Member.
The best... seek out experts. It is sooo complicated.
2 clicks at the track by me, disaster.
2 clicks by a pro suspension guy that knows what he is doing..
Priceless.
P.S. how are things in Italy ???
Locking down in Tucson Az.
Peace annnnd Go !
awesome video man. keep up the good work.
yes, definitely it's helpful
Your explanation was very clear and simple to understand. I would like a video where you explain what you would chane on bike for trackday riding. thanks
This is the best video ever!!
Awesome video keep them coming, your the best UA-camr out there
great video !!!! thanks
great explanation
Very clever, thank you.
very good video for people hardly understand anything like me , make more videos for technical knowledge like this pls
I'm a mechanical engineering student, and I've learned that both gases and fluids are compressible, but in the cases of most fluids, the amount of energy needed to compress them (by little!) is huge. That's why it is a good approximation to say they are uncompressible. Anyway, I'm sure that in such serious cases they calculate with it.
The explanations in the video were professional, thank you for working with it!
best utubers moto!! i love it
Excellent!
You are just amazing 😍
Great animation
Nice video, thx br0!
HO204 + NIX30 for my RC51 sp1
^^
Very good!
Very interesting enjoyed that
Very informative🤗
Thanks 😊
Very nice and clear explanation. This answer my years of question, why kawasaki made Showa BPF Fork Big Piston. Why The fork had different function not like other conventional fork. And now, i know why.
I hope you will cover something more about the forks in the next video, Spero che coprirai qualcosa in più sulle forcelle nel prossimo video. ♥️
Another informative video!!
My question is what bike shoud you buy to start going to the track..i see the pros practicing on mini gp, on Motocross,on big bikes and any type of bikes...
Should i get a small bike and start practicing on small tracks(go kart tracks) etc or i should start practicing with my 600
❤Love from india 😍 big bro 😇
Hi Alberto, thank you for your videos. I think your content is one of the best in youtube, I learn a lot from you! I know you get a lot of comments, but who knows maybe you will notice mine... I have just bought a Kawasaki H2SXSE and I have heard a lot of comments that it really needs a steering damper. I don't ride on the track that often, but I do ride a lot in Germany with no speed limit. Do you think its worth to install it? Or its useless outside of the track? Thank you!
Love from India 😍😍😍
I think the bicycle suspension does have the shims at 16:25, they are located just above the bypass, do you see? The animation even has them open during compression on the left :-) On the other hand, the rebound shim seems much thicker, not opening much it looks like.
make a video on who to setup suspension!
Something I need to clear out:
- Adjusting rebound and commpression does change the speed of the spring. But when we apply a fix amount of force but in 2 different periods: very long and very short time; the suspension will travel differently
- Adjust preload doesn't change the spring stiffness; the only way is to change the spring.
Or I have a miscomception.
Very very helpful video, bro!!
Shout out men., thanks
Bottom out is correct!
Hey man, honestly, great content and crucial for motorbikers to understand. But unfortunally most of the riders dont care about these things. You surely deserve more views and followers. Hope you are doing well.
Woah, this video is so good.
No clickbait, straight to the point to not waste time and very understandable.
Edit: You definitely deserve the 1.1k likes. Also, I understood this video more than the other 30 min videos I have seen.
Yup, other videos on suspension are waaaaayyyy too complicated.

Hi naska hope you are doing well, i have been watching your videos because I’ve learned so much by watching and listening to tips and mistakes u have made in the past, as a new rider like myself at the moment i wanna thank you for starter.
So i have a question, i have recently purchased a 2012 R1 and the previous owner have it lowered one down for stock hight, i remembered watching one of ur videos and you were saying to adjust saddle hight to the rider’s hight and adjust handles out if possible, but I’m being told by my friends that with it lowered it will affect cornering and that i should get it raise back to stock hight for better handling. Is this true and do u recommend raising it back to stock hight ?
I am 188 pounds and 5’.9” tall.
Thanks in advance!
How I understand it:
Spring -- For up and down movement and to comeback to its original state.
Shock absorber -- To slow down up and down movement and reduce bounce using friction and other factors.
