- Simplified is a new series on PowerDrift that aims to make automotive concepts, technology and ideas as easy to understand as possible. These short videos take the questions you have and clear the air around the what, how, why and when. In this episode, Shumi is answering one of the more popular of the questions we get -- the difference between a right-side-up, or normal telescopic fork and an upside-down fork. And to be honest, the difference is smaller and more nuanced than you think!

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
Every School needs a Teacher like Shumi... ❤️
@@jayakrishna2305 stupidity level of this comment 9999999
Well I am ok if this comment seems to be stupid
@@jayakrishna2305 What’s wrong with becoming a mechanic?
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.
Good idea

Good Topic!
Yes
Definitely interested
As expected shumar is that friend who teach you 10 mins and pass you the exams. thanks
These segments remind me of Ari Hennig's MC Garage videos that he used to do a couple of years ago.
he still does that with revzilla. called as "the shop manual"
He still does those series... Very informative 🙏
@@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.
Yes this is our indian version of that and I always like to hear from Shumi.
suggestions for topics 😂:
1.2 ,3,4 valve engine
2.rider triangle
3.sprockets
Need an explanation about the differences between a box section Swingarm and an aluminium swingarm. And why swingarms are related to handling.
Yes

Good Topic!
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.
@@manthenvashishth3769 thanks I got it 🙌
When is the next part of Holy shift coming???? Absolutely loved the last one.
Yes please
Shumi please provide us the regular bike reviews more often. We just adore the way you explain everything to noobs like me❤️
This series is really informative. Just a suggestion discussion on drum brakes and disc brakes. It also can feature advantages of ABS
Great video Shumi sir!!! Please talk about different types of *swingarms* in next video
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.
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.
Suggestion -
normal clutch systems & hydraulic clutch systems
Single & multiple cylinder engines
Explained really well …. All these years of doubts based on this topic just got erased after seeing this video..
thanks a lot..
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 !
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
I have listened to all your podcasts till now Schumi. Thanks for clearing my doubts. Keep rocking bro.
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)
about oil there's already a video made by them open the channel its 6-7th video
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.
wow. I have never seen such a simple and brief explanation as this yet very clear and effective. good job
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.
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
Explained very clearly, precisely and kept it simple with basic explanation👌🏼
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.
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.
Good topic covered 👌🏻.
Can you please cover the topic about the different grades of fork oils and their applications.
As a motorcycle enthusiast what I like is how you explain at engineering level in very simple form. Thank you brother.
Great video as always PD! Can we expect more of Shumi and Varun’s podcasts ?
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 can't stress this enough, best and most concise explanation ever !!
That was amazing. All the videos talk about high performance this and that but you explained it mechanically 👌👌
Thank you sir, for clearing my doubts and knowing about oil seal cap
Awesome coverage on front suspensions........ Would be great if sensei shoomi would have covered rear suspensions as well
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?
Brilliantly covered the topic, as always. Kudos Shumi... you're awesome man.
Would love to see a Simplified or a more elaborate video from PD on Riding gears and it's importance. Which I feel perhaps is very underrated subject and safety is taken for granted.
Simply terrific explanation! Every school needs a teacher like him. Bravo! Thanx
Brilliant! First time I have ever heard this explained and it made sense, thank you.
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.
What's the idea behind having open chain rather than a covered one like the commuters.. any advantage apart from asthetics
That's a grade school level of explanation, easy to understand. Thank you so much.
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
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.
now this is the type of explanation done by the professionals. Loved it.
Well said!! Each type of forks has the specific JOB. Informative 👍👍👌
I love this series! Plethora of expert level knowledge..for a layman!
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 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.
thank you for the seal cover suggestion .. that's gonna help me later in term of maintenance ..
Very informative... Kudos to PD team for doing this 👏👏
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)
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!
Can you make a video about difference in coolant type and colour
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.
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..
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!
Thank you for explaining the terminologies in a simplified manner
You have a good teacher in you Shumi.
in the old days all forks truncheons were covered with rubber protection, but ppl thought it marred the looks so now the
Great explaination! Plz make something Engine working. Block, crankshaft, compression ratios etc
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
So much info on forks in just 6 minutes! just loved the video! Living encyclopedia = Shumi!
Watching u for the first time...clear and crisp. Would u plz explain slipper clutch
Thank you. Was having trouble trying to understand this.
Just simply and easy explanation. Thank-you Sir.
Please do a comparison between oil cooling vs liquid cooling 🙏
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
Answered my all questions I ever have about these two. 👍
Shumi should start speaking on meaning of life and life lessons as well... Powerdrift podcast have nothing but life changing...!! Kudos..👍👍
Clear and neatly explained
What an amazing piece of info. Keep it PD 💕
Please continue with the simplified series, it's really help full
I feel you missed explaining spring preload, suspension travel, using stiffer springs, using heavier fork oils, changing RSU forks for USD forks or vice versa etc. Could you do a part 2 video on these. Much appreciated and great explanatory video. Greetings from Sri Lanka!
Great video guys. Can you please make a video on preload, compression and rebound adjustment on suspension springs.
Fixed Vs floating brake calipers..would love it if you covered those!
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
Heyy shumi! Great info...would love to understand the difference between air cooled and liquid cooled engines
Hey this video is very useful for every biker thank you Power Drift and Shumi sir
Please make an another video on chain drive vs belt drive vs shaft drive which one is better, and there advantage and disadvantage. I hope that you will make a video on this subject please Shumi sir
The explanation was very clear as compared to any other videos out there
N3xt one mono shock vs dual shock for rear side. Good video this.
Basic suspension tuning with respect to adjusting sag, preload, compression and damping for one’s own weight. I know dave moss is the OG is this field, but it would be nice to get a basic guide from Shumi. Cheers
Can You Please Explain About Headlight,Led vs Halogen
Awesome Shumi! I love learning details of the things I love!😅
I request you to take the topic of exhausts: stock vs modified/slip-on! What difference does it make in performance and does it reduces the engine life? Also, is a change in better air filter mandatory with change in exhaust?
Need a video about engine braking and rev matching
Fantastic video ..... The only thing missing was the discussion on unsprung weight... That's one more advantage an usd provides... Cheers...🙏
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. 🙂
Great info pd,
Can you explain the different engine setups ? Single , double cylinder, inline four, Vtwin etc ?
Wow dude. Amazing explanation 👏
Hats off Shumi !!
Brilliant as always ! Thank you Shumi !
Excellent explanation. Clear and concise.
Excellent answer & explanation. Thankyou 🙏🙏
As of now my lecture is going on this topic ,i got notification about this ,left the lecture and join the powerdrift video ❤️❤️
Great explanation, thanks shumi. Can you plz also clarify the myths of engine breakdown, I mean why do we have to drive fresh new bikes slow, for a few hundred kilometers ??
An addition to Schumi's summary is the unsprung weight advantage that USD forks offer (lighter stanchion adding to sprung mass)which is a significant factor in performance motorcycle handling & braking. On a street bike or lighter machine, the weight difference is marginal & a USD is almost an expensive cosmetic upgrade.
That's the reason behind why activa has poor suspension build due usd and also the reason for break fail in activa's
You might have missed out another technical benefit of USD forks over RSU forks, i.e: unspring mass reduction. The female slider block is usually much heavier than the stanchion, which means the RSU suffer from the disadvantage of having most of its mass in the un-sprung section, which translates to poorer chassis stability to road undulations and vibrations. More sprung mass ratio typically leads to improved handling at the cost of more expensive/sturdier suspension systems.
Best best best way of explaining bang on points 🙏
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!
Beautifully explained 👍👍 .
This question piqued me and as soon as i wanted to search up on it, i almost instantaneously knew that PowerDrift would have it covered 🙂
