People who are have a passion for motorcycling and does go for long hauls on their motorcycle or do tracks or do off-roading need to have this knowledge on need-to-know basis. This knowledge sharing and understanding is not for all. Its not for the average joes or jayakrishnas (as it seems here)
@@jayakrishna2305 What Shumi explained was something abt Spring Action n Fluid Mechanics... Well that brings me to a question... Are you an Arts/Commerce Student?
Hey PD, could you please make an episode on different types of motorcycle chassis - trellis and perimeter frames, single and double downtube, etc. It would be interesting to understand their pros and cons. Thanks.
@@Thegeekishnerd13 Yeah I know but most Shop Manual videos feel a bit more technically inclined than both Simplified and MC Garage. Just a feeling. Cheers.
Swingarms directly are related to handling. They are vertical pivot one end of which has the rear wheel of bike connected with it and the other end is connected to Frame of bike. Swingarms can be one sided and 2 sided. Weight of swingarm, it's construction etc affects the handling in either way be it good or bad. An aluminum swingarm is better than box section swingarm cuz it's a cast or forged part which is lighter than the box section swingarm and will imply lighter and easy controls and thus better maneuverability and improving handling, moreover a forged aluminum swingarm will have more structural integrity than the cast swingarm cuz of the arrangement of the aluminum particles in it and will be lighter too. A carbon fiber swingarm will be even better than aluminum cuz it's lighter than aluminum and more stronger than aluminium . That's the reason why forged alloy wheels of cars are better than die cast wheels (only on the asphalt). The arrangement of particles while forging gives them more structural integrity than the cast where the metal is just melted poured in a die and then made. Hope you got your answer pal.
You missed very important part: upside down forks installations have much less unsprung weight. This is crucial for better handling, turning and response for road imperfections. Both steering and comfort will benefit from USD.
I have a little dilemma up here... "MC garage" on the other hand, does have a completely different opinion, stating that aesthetics is the major difference. I'm confused.
There is another reason for USD forks on performance motorcycles. The part that moves about is the stanchion which weighs less than the female part (containing oil, springs and the weight of the fork itself). There fore, the weight of the moving component is lesser giving a better performance improvement.
a little misunderstanding that seems like all the people in the world did is, and upside down front fork is actually a telescopic fork too, but inverted. so saying "telescopic vs upside down" or "telescopic and upside down fork" differences is actually wrong.
Very clearly explained! I hope this clears up the heads of those R15 and MT15 owners who keep complaining that their bikes are inferior to ones sold overseas.
Being an engineer myself, it was just a breeze watching through and understanding every bit of what you just explained, much like reading through a well written book. Good Job
I had a question. Why did bike manufacturers switch to monoshock suspensions for the rear passenger when a telescopic suspension seems like it would be more comfortable? Also, am I wrong in thinking it would be more comfortable? Seems 2 is better than one.
That's a very faulty assumption, telescopic forks have two legs therefore requiring two sets of wiper which will give twice the stiction, many times more if they are gummed up by dirt. The reason why the motorcycle industry hasn't switched to linkage forks (either one or two-legged) is because of economy of scale and consumer perception, most bikers care so much about looks they want the manufactures to sacrifice improvement in function to keep the aesthetics; you don't see telescoping shocks for the front wheels of cars, unfortunately MTBs followed in motorcycles footsteps because telescopic forks came first on motorcycles. A well designed linkage is always better than two giant sliding tubes, it can offer less brake dive, less unsprung weight, more small bump sensitivity, be virtually maintenance free and make use of the plethora of different rear shocks already on the market.
What a teacher... Absolutely awesome! Can you please do a video on how exactly does a cornering ABS work and how different it is from a conventional ABS?
I completely agree with the cooling method comments and the suspension comments. The particular means of cooling or suspension is given on a bike for optimum performance. Everything should not be about just asthetics, looks or spec bragging rights.
Thank you so much sir, people are so much focused on having USD forks, disregarding their requirements and jump to costlier motorcycles on basis of that. It cleared up that we don't necessarily need USD forks on a minor 200cc motorcycles.
Shumi I have recently started watching your videos and I am hooked !! You are probably the most sensible and knowledgeable motorcycle reviewer I have seen ! Like your philosophy and way of thinking and also your ever so sensible advice. If more bikers took your advice roads would be much safer. Respect !
Can you make a video about best oil to run your motorcycle on , the best tyres to run a motorcycle on and DIY service pack to help riders maintain their motor cycles (pretty please)
way you elaborating is really very effective for the viewer , which don't have much technical knowledge .and my question is difference between spokes wheel and alloys ? like even bigger bikes use spokes like africa twin many more!
Also, with upside down forks the bigger and heavier part is “steady” while the smaller and lighter part is traveling up and down with the wheel... therefore, it’s less mass to get it’s movement absorbed by the springs and dampeners (and ultimately by the chassi)
Hi Shumi, This playlist is amazing and the way you explain it, well I wish you were my school teacher for every class. From the topic of USD and telescopic suspension systems, I would request you to also shed some light on rear suspensions: Mono and the dual set up. Second topic I can think of would be lights: halogen, LED and projectors. Also since LEDs generally blind the oncoming traffic even when their throw isn't that great from a rider's perspective. Generally LEDs are very powerful. Please also explain use of auxiliary lights. 3rd and the most important : With riding schools out of reach and knowledge of most people, how can we improve our skills.
Great video PD and Shumi your screen presence is amazing. My two cents- apart from the structural function, upside down forks also result in a lower unsprung mass thereby creating a positive impact on handling and steering among other things.
Telescopic forks are better for Indian roads and hence we don't see a litre class bikes often in India we don't need USD forks but now companies started using USD forks as a gimmick
Wish you also talked about unsprung mass and the benefits in handling that comes when you reduce it. USD helps in that as wel.. also it's normally a challenge to keep the CoG low when you use a USD at the front.
gosh!! splendid video!! I really had this doubt about forks and had no clue on what precisely to google. you people made my day, PD!!! thank you for this series, powerdrift Shumified
Hey PowerDrift, could you guys please make a video on different types of engine: v-twin, inline 3, inline 4, etc and their impact on the performance. Also, a video on CC, BHP, Torque would be really helpful. TIA!
Dude, I juat found you and you have a video for every part that I want to know about right now! Subscribed, keep up the work (and constantly update with time) 👏🏼👏🏼🙌🏼
Thanks Shumi for the knowledge you give through Simplified. I would like see a video on difference between oil cooled engine & air cooled engine. Hope to see this soon..
Hey #PDArmy, we hope this clarified your doubts! Hit that Like button if it did! And let us know below what more you'd like us to cover!
Next video on bike gears why do we need to change gears (upshifts and downshifts) what is the ideal speed to keep a particular gear or change a gear
Can we have a video on break and clutch adjustable livers how does it work and what difference it makes with normal non adjustable once...
Hub Center steering ( motorcycle) Vyrus , pls do a episode on this topic, pls......
Can u make the next video on engine cooling systems (like air-cooled, liquid cooled, etc.)
Neatly explained, great video

This series is really informative. Just a suggestion discussion on drum brakes and disc brakes. It also can feature advantages of ABS
Explained very clearly, precisely and kept it simple with basic explanation👌🏼
I have a little dilemma up here... "MC garage" on the other hand, does have a completely different opinion, stating that aesthetics is the major difference. I'm confused.
Great video Shumi sir!!! Please talk about different types of *swingarms* in next video
Explained really well …. All these years of doubts based on this topic just got erased after seeing this video..
thanks a lot..

There is another reason for USD forks on performance motorcycles. The part that moves about is the stanchion which weighs less than the female part (containing oil, springs and the weight of the fork itself). There fore, the weight of the moving component is lesser giving a better performance improvement.
More importantly the lighter part is farther from the CoG as well as mounting points. So performance is better
I have listened to all your podcasts till now Schumi. Thanks for clearing my doubts. Keep rocking bro.
Best best best way of explaining bang on points 🙏

As a motorcycle enthusiast what I like is how you explain at engineering level in very simple form. Thank you brother.
Why should we prefer front brake more than the rear
Also what I have read is that component of unsprung mass is lesser for upside down forks , making the overall job of suspension unit easier .
👍👍👍
Yes but explaining unsprung mass in itself is a whole Simplified episode
Suggestion -
normal clutch systems & hydraulic clutch systems
Single & multiple cylinder engines
I had a question. Why did bike manufacturers switch to monoshock suspensions for the rear passenger when a telescopic suspension seems like it would be more comfortable? Also, am I wrong in thinking it would be more comfortable? Seems 2 is better than one.

Great explaination! Plz make something Engine working. Block, crankshaft, compression ratios etc
Very good series.
Dumb people wont believe normal experienced folks, But if it comes from a good influencer, Its great !
I wish my biology class was this easy.
What a teacher... Absolutely awesome! Can you please do a video on how exactly does a cornering ABS work and how different it is from a conventional ABS?
I can't stress this enough, best and most concise explanation ever !!
You have a good teacher in you Shumi.
Awesome coverage on front suspensions........ Would be great if sensei shoomi would have covered rear suspensions as well
Damn I never knew forks had male and female parts♀️♂️😂
Even sockets 3pin plugs are also nomenclatured as male female for easy understanding 😅😅
anytime any long thing goes into a hollow thing, they are named male and female... Now you know!!!
._.
Welcome to technical terms lol
We use it everyday in electronics
Anything which goes inside is a male part. 🙂
Simply terrific explanation! Every school needs a teacher like him. Bravo! Thanx
I completely agree with the cooling method comments and the suspension comments. The particular means of cooling or suspension is given on a bike for optimum performance. Everything should not be about just asthetics, looks or spec bragging rights.
Good topic covered 👌🏻.
Can you please cover the topic about the different grades of fork oils and their applications.
Guys let's request them to do on ... when air cooling makes sense and when oil cooling actually makes sense..
Thank you so much sir, people are so much focused on having USD forks, disregarding their requirements and jump to costlier motorcycles on basis of that. It cleared up that we don't necessarily need USD forks on a minor 200cc motorcycles.
It's funny he says "500cc commuter lol".
Only RE 500s are considered commuters. At least for me.
Prof. Shumi always rocks....
Good practical and useful tips 👍✌️

about oil there's already a video made by them open the channel its 6-7th video
Great video as always PD! Can we expect more of Shumi and Varun’s podcasts ?
Shumi teaching like IIT professor
What's the idea behind having open chain rather than a covered one like the commuters.. any advantage apart from asthetics
Please make a video on why the pillion seat on bikes are raised and even if they are flat why they are not long and wide like scooters
tank god the series is free lol
As always...great work...can you make a video explaining the torque and horsepower aspects? How do producers measure them?
Thanks Gaurav! That might be a good idea; we shall try!
how does suspension plays major role in racing? Not only bikes but cars also. Would you explain it?
way you elaborating is really very effective for the viewer , which don't have much technical knowledge .and my question is difference between spokes wheel and alloys ? like even bigger bikes use spokes like africa twin many more!
in the old days all forks truncheons were covered with rubber protection, but ppl thought it marred the looks so now the
Thank you ✌
Also, with upside down forks the bigger and heavier part is “steady” while the smaller and lighter part is traveling up and down with the wheel... therefore, it’s less mass to get it’s movement absorbed by the springs and dampeners (and ultimately by the chassi)

Great video PD and Shumi your screen presence is amazing. My two cents- apart from the structural function, upside down forks also result in a lower unsprung mass thereby creating a positive impact on handling and steering among other things.
Amazing explaination...
Came here after Hero's media ride launch of Mavrick 440, as they provide USD for Harley x440, whereas Telescopic (RSD) in Mavrick.
Telescopic forks are better for Indian roads and hence we don't see a litre class bikes often in India we don't need USD forks but now companies started using USD forks as a gimmick
Can you do a video on rear suspension too...there are many mono shock...dual shock and then adjustability terms like front load and pre load
Thank you sir, for clearing my doubts and knowing about oil seal cap
Thanks for the detailed explanation, really helpful. Can we get to know about Cylinders in engine and how do they function. Thanks in advance!
thank you for the seal cover suggestion .. that's gonna help me later in term of maintenance ..
Please do a comparison between oil cooling vs liquid cooling 🙏
Hi shumi
Nice to see and hear such content for new generation bikers pls make content on disk brake and drum drake and abs on both the brakes
Can you make a video about difference in coolant type and colour
Make a video on Compression ratio
Thank you for explaining the terminologies in a simplified manner
I was hoping you'd include the part about sprung and unsprung weight difference
There’s also the idea of mounting heavier things closer to the CoG. But I thought 4 things esp the idea of unsprung weight would complicate the issue
Differences between dry and wet clutch shumi
Wish you also talked about unsprung mass and the benefits in handling that comes when you reduce it. USD helps in that as wel.. also it's normally a challenge to keep the CoG low when you use a USD at the front.
That was amazing. All the videos talk about high performance this and that but you explained it mechanically 👌👌
Hard seat vs soft seat
The explanation was very clear as compared to any other videos out there
Thank you. Was having trouble trying to understand this.
