SMOOTH GEARSHIFTS AND EASY REV MATCHING | DOWNSHIFT AND ENGINE BRAKING ON CLASSIC 350 REBORN

[@Dheeraj_7922]

Extremely informative. I did it on my bullet 350 next gen and got exact same results

[@sormadaa]

Very well explained, buddy. I have been doing rev matching since the past one month, however i learnt it by "accident". And since then, almost 90% of the time I'm downshifting with this technique. What i have also noticed is that with rev matching, one can easily get rid of the bad habit of pulling the clutch every now and then (beginners). Really efficient and smooth, also the engine braking helps.

[@alongwithamit.]

Exactly! Very less use of clutch overall and smooth rides

[@adhils9633]

Pro tip :- if your vehicle is pulling backward, then increase the throttle blip.. 2) You can do the opposite for gear upshift.. put a bit pressure on the lever and release the throttle and press clutch at the same time ..the gear shifts automatically...for gear down also lay your leg on the lever and blip , the gear changes automatically

[@dinjarin4243]

💯 Accurate

[@pradyu.1]

I use to do this on my old motorcycle, later I learnt that this was affecting the life of my machine's clutch. So if I have to upshift, I raise the rpm slightly higher than the sweet spot and shift, downshifting I let the speed and rpm drop lower than sweet spot to change so it's always smooth shift. I ride CB350, for a notorious long gearing, this seems really important for longer life for gears...

[@pawangaire168]

Yes, rev matching does affect the clutch plate, but in a positive way: * Reduced Wear: Rev matching minimizes the speed difference between the engine and the transmission when you shift gears. This results in less friction and wear on the clutch plate. * Smoother Shifts: Rev matching ensures smoother downshifts, reducing shock and strain on the clutch and other drivetrain components. * Prevents Stalling: When downshifting without rev matching, the engine can slow down too much, risking a stall. Rev matching helps prevent this. Overall, rev matching extends the clutch plate's lifespan and improves the driving experience.

[@Pam-zr7kt]

This is useful if you ride on a higher rpm... But for a cruiser you'll mostly ride in mid to low rpm where it is not required... You can down shift after slowing down applying brakes.

[@alongwithamit.]

Agreed! But, REs are built different. Sometimes a particular gear will just not tend to shift at speeds. Also, in other cases the gear engagement makes a hard noise. It may not happen often but surely happens. Thus, this technique comes in handy.

[@thor1626]

Could someone clarify a few things? I’ve been riding bikes for a long time but have never ridden heavy bikes; I’m used to riding lighter models like the Passion Pro. This downshifting technique refers to shifting down a gear, for example, from 4th to 3rd. You typically do this to slow down or when climbing a steep road, correct? Usually, if the incline isn’t too steep, I just press the clutch a few times to generate power. Is this incorrect, or should I be using rev-matching in this situation? When upshifting from 3rd to 4th gear, I first increase my speed to reach the appropriate range for 4th gear, then release the accelerator, press the clutch, and shift. Is this the correct approach?

[@OneMemeEveryday0711]

i dont know but have been doing this since class 11th didn't even realised till now

[@luffythestrchykid]

Here's advice from a Noob who now has figured out rev matching in classic 350 so that you don't face any difficulties. From experienced ppl POV rev match happens when all done at the same time... clutch, gear, throttle. For newer riders, a tip: When upshifting CLUTCH -> GEAR ->THROTTLE is the sequence when down shifting THROTTLE -> CLUTCH -> GEAR is the correct sequence I was able to upshift properly but faced problems during downshifting if u follow same sequence as upshifting, bike will jerk. That's when I figured out this. Hope it helps.

[@alongwithamit.]

It’s all simultaneously at the same time. But i feel first comes clutch, throttle and shift in case of downshifts

[@Knife-rr2cs]

Clutch rev shift all at the same time?

[@alongwithamit.]

yes. but if i break it down to mili seconds, the process looks like this: 1. Clutch 2. Rev (Blip) 3. Shift

[@Knife-rr2cs]

@@alongwithamit. thanks sir love your videos 😅😅

[@ThushantNair]

Doubt! When Im downshifting with rev matching from 45Kmph in 4th gear to 3rd its smooth without jerk but the engine makes a noise like... RRRRRRRRrrrrrrr. Is this normal? I'm concerrned because its unusually loud like engine is crying 😕. I couldn't hear the same sound from your video. I'm noob in motorcycle riding.

[@alongwithamit.]

Yes the RPM on a lower gear is generally higher which is why you hear that sound and is normal if theres no jerk

[@umeshjambagi4175]

I changed my clutch plate at 80000kms i don't do any rev match speed ke hisab se change karna hai kuch jyada understanding engine reponse gear loads is needed Kuch log jyada speed me gear down karte hai whats the reason low gear me engine stress karna ise rpm me high gear lagta hai it is trend now but in old days people play game with toe finger DEPENDS ON SKILL

Yes wait for it to slightly come down and clutch-blip-shift

Rev match downshifts using the clutch is perfectly okay but doing it without using clutch is definitely harmful

[@bartsimpsonofficial5740]

Nice video bro...can this same method be used while upshifting as well??

[@alongwithamit.]

up shift will be slightly different here while downshifting you pull clutch, throttle and shift while upshifting, it will be releasing throttle, clutch and shift

[@bartsimpsonofficial5740]

​@@alongwithamit.Ah now I realise that's what I've always been doing LOL thanks a lot man.. I've come across lots of rev-matching videos and yours is the easiest to understand. Keep up the good work mate!

[@sankalpkatara6346]

RE instructs in its manual to press the clutch fully to shift gears is that necessary? one you've pressed the clutch past the engagement point, what's the point of pressing it further? Also in rev matching,it would be very inconvenient to press the clutch fully and do a blip at the same time.I could see in this video that you were only pressing the clutch upto the point its disengaged & no more (which makes sense to me).One more question - when i am practicing rev matching ,am i damaging the clutch plates every time i get the timing wrong & get a jolt?

[@alongwithamit.]

Once its disengaged, it good to go. But sometimes is may feel its disangaged but the clutch plates are slightly engaged internally which may be bad in the long run. Its a good practise to engage fully it may if done aggressively but once learnt it becomes muscle memory

vai i've few questions. its been 6 months that i've owned a reborn and i'm from KTM, Nepal. this is my first bike before it i had scooters(dio and ntorq). i dont know how to explain my issue. what i feel is the pickup lag during uphills . i've rode other bikes but didnt felt the pickup lag. while complaining at the SS. they say the bike is fine, enfields are not for uphills and it dont performs like other bikes. is it only me? or is it the bike with issue? how do you feel please do let me know. or since its my first bike, the way i've been riding is wrong? what i do is i change gear only after it asks. during uphill, i rev till it asks for 2nd gear and while changing the gear the bike doesnt pulls well. and again if change to 1st gear the engine asks for 2nd gear. but changing to 2nd gear power lags. i dont think its a clutch plate issue, cz it pulls very well in plain roads, i've hit upto 65 kmph (not a speed lover) i dont know how to explain it. hope you've understood me. pls explain or make a video.

Bro but how to apply front brake while rev matching ..can we do it

[@alongwithamit.]

[@dreamerchawla]

Is this also the reason why sometimes during downshifting, the gear just won't shift down unless I release the clutch once? Usually happens with me if I am downshifting multiple gears

[@alongwithamit.]

Yes! Can be! maybe the speed is too high for that gear that it just wouldn’t shift normally.

[@sujaltamrakar1246]

Well i am a new driver so what i have learn is to stop the throttle and pull clutch change gear so this teachique is opposite of that is it ok to use this teachique in old bike

Bro, As now Chrome Bronze is sold without Alloy wheels i.e. spoke wheels, is it worth to buy ? (As of now it is not offered in MIY) Or Should I go for alloy wheels of Marsh Grey or Stealth Black? Is there any Rear Disk issue in classic bikes?(I saw it some KZbin videos).

[@alongwithamit.]

The chrome variants and all other variants have gone through an increase in price recently. Also, yes the MiY doesnt have the alloy option now. So if you plan to add alloys you will still have to change the tyres to make it completely tubeless which will bump up the cost a lot. I personally like gunmetal grey over stealth black, both of them come with alloys as stock. No issue from the rear disks. If a squeaking sound comes from the disc, it will go away if we rub the disc pads and blow it with air.
