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.
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 are a university of racing mechanics ... Your explanations make everything so simple to understand .. feel blessed to have subscribed here ..thnxx a lot 👍
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.
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.
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
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.
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.
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 !
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.
One of my favorite TH-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 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.
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
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!
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.
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!!
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.
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!!
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.
Does the orientation of the shock have an affect on the performance? For example Why is the hypermotard 959 sp have the rear shock upside down. Does it matter or do you get the same results both ways ?
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!
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.
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
Che libro è migliore per capire il funzionamento della sospensione della moto, Dinamica della moto di Vittore Cossalter, Dinamica e tecnica della moto di Gaetano Cocco o La progettazione della motocicletta di Fabio Fazi?
I seen a few of your videos I’m a fan and it was very interesting in this video but one thing I don’t know if you were able to cover all during as why are the suspension so expensive and sometimes it feels they’re not obtainable the regular pocket maybe that something you should ask the company I don’t mind paying for high-quality as long as is affordable
I have a question alberto naska, I have struggels on a race mtoor when to use the rear brake. by braking straing, by steering idk. can you explain when to hold and release rear brake?
M I’m not a expert but from my experience, since we all know the rear brake isn’t really the one who stop you, the front brakes do that works, so I always fix my rear break not to tight even a bit on the loose side because the rear wheel was so easy to lock, so with motor compression and the front break I was working hard, but just touching the rear, and when I could feel the rear wheel lift up , in short more then often I used the rear break to keep the rear wheel to the grounds. Hope that help in a sense , but theirs another thing , it’s that now almost every bikes as anti-locks and tracks controls electronics.
@@claudebaron9525 yes thank you i understand, but i mean, i need to use the rear brake for shorter steering and steering and suspension stability,. but i just need to know at which time i need to press it in to have more stability and be able to steer later into corners
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.
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
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.
Now I understand what other 100 people were trying to explain me. Grazie!!!
Decisamente meglio della maggior parte dei professori che ho incontrato fin'ora a Ingegneria Meccanica...

Very informative video Naskaa👍
But I would like to say today that whole world stands with Italy in fight against Covid 2019😊Stay safe
You explain this better in english than anyone so far.... thank you so much.
Your English is BETTER, than many English only speaking people I know. So long!
Fantastico Naska, Alcuni insegnati potrebbero imparare da te. Ti prego continua a fare video spettacolari come questo.
I love your videos, one of the best suspension videos i have seen
As usual, fantastic explanation Alberto. Lots of love from India.
Using the rubber balloon and arm is a superb simple example. Never thought of this example.
The BEST AND MOST IN-DEPTH LOOK AT HOW SUSPENSIONS WORK I HAVE SEEN IN 30 YEARS....:)
Very clear explanation brother. Thanks you.
Bravo! Nice informative video with good visuals 👍🏽

This video is the best thing i've watched so far in 2020
best utubers moto!! i love it
I clearly understood about the suspension was very useful
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
genius engineering to have the wheel rotating together with the brake calipers
very good video for people hardly understand anything like me , make more videos for technical knowledge like this pls
Great explanation, thanks. 👍👍
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!
Thanks Alberto ! Excellent explanation. Your video made things clear :-)
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.
Great Video. Thank you. The quality of your channel has already been good but now it has become really great.
Absolutely fantastic video thanks so much.!!!
You make it easy for me to understand a quite complicated subject.

Great job amigo. Very interesting! Thanks.
Very good explanation! Now i understand a little bit better how it works, thx for that Alberto! ✌️👍
very good explanation of this complex theme
Best explanation ever.Thanks Albero awesome vid.
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.
Very, very good information. Looking forward to seeing the part 2 which is adjusting rebound and compression. Cheers 🍻
Thank you Naska for this video! It was excellent!
Superb explanation!
i love how you explain it well . Your number no. FAN from Philippines!!!♥
this is slowly becoming my favourite youtube channel. keep it up
Very good video and I let to say you'are daring, trying to explained a so difficult subject!!!!
Congrats!!!!
Awesome video keep them coming, your the best TH-camr out there
awesome video man. keep up the good work.

Thanks a lot bro for the videos you have posted! Very informative! Thanks for always sharing your knowledge!!
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.
Brilliant!!Thanks man!
Very useful info, thank u.

Great video. Thanks for the info. And, "bottoms out" is what everyone I know says...
Great animation
Very informative🤗

Thank you very much my friend .
Love the video Alberto think I'll have to watch it a few times to really have it :D thanks Love your content
Very good!
That's great information, thank-you
make a video on who to setup suspension!
Does the orientation of the shock have an affect on the performance? For example Why is the hypermotard 959 sp have the rear shock upside down. Does it matter or do you get the same results both ways ?
Interesting and very informative! Always great content☺️ keep it up
You are just amazing 😍
