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)

[@KarteekRakshit]

Yes

[@AbhishekBalagaon]

[@lutenic6111]

Good Topic!

[@manthenvashishth3769]

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.

Yes this is our indian version of that and I always like to hear from Shumi.

[@Rajukjha007]

As expected shumar is that friend who teach you 10 mins and pass you the exams. thanks

[@igorpietak937]

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.

[@maharshipratap9609]

Shumi please provide us the regular bike reviews more often. We just adore the way you explain everything to noobs like me❤️

[@prameethprabhu]

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.

[@shu_mar]

More importantly the lighter part is farther from the CoG as well as mounting points. So performance is better

[@AchintyaPandit]

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.

[@prasadkalekar1163]

This series is really informative. Just a suggestion discussion on drum brakes and disc brakes. It also can feature advantages of ABS

[@AMVideoViewer]

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.

[@Finnv893]

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.

[@mks2822]

As a motorcycle enthusiast what I like is how you explain at engineering level in very simple form. Thank you brother.

[@acescok]

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

[@arvindkrishnan5816]

I have listened to all your podcasts till now Schumi. Thanks for clearing my doubts. Keep rocking bro.

[@kitchugeths]

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.

[@UnShEeP924]

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.

[@afletra]

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.

[@baravinds]

Explained very clearly, precisely and kept it simple with basic explanation👌🏼

[@vaibhavjadon8008]

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.

[@varun_wadekar]

Great video Shumi sir!!! Please talk about different types of *swingarms* in next video

[@rahulsakunde9431]

You have a good teacher in you Shumi.

[@br1pres8]

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)

[@nabeelpa2564]

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 .

[@nabeel5757]

👍👍👍

Yes but explaining unsprung mass in itself is a whole Simplified episode

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.

[@rishijaiswal1]

[@prabhu200519]

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.

[@kvguitarist]

If the front fork feels too soft, there may be too little oil in it. If it feels too hard, there is probably too much oil (or dirt) in it. If the front fork falls inwards or outwards in the curves, the fork crowns must be adjusted by either raising or lowering them. If one stuffing box starts to leak, you should still replace both at the same time. The risk that the second stuffing box will also start to leak is high.

[@harishkumaar9085]

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.

[@Bikenstein]

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.
