Read the first two lines in 'Clutch Control' Section of Tips for You and Your Bike and reply this topic.
Does it mean that you should sometimes avoid using the clutch while upshifting the gears but always use the clutch while downshifting the gears?

woh, have never heard of this before man, i mean doesnt you ruin your vehicle by doing so. You always need to use your clutch to change gears.

Even I've not heard of it before. I really have no idea of this.

as far as i have heard, if the engine is at the correct rpm, you do not need to use the clutch while upshifting. while downshifting, you will have to slow down enough to attain the correct rpm which is not always possible, so you will have to use the clutch.

but it is always advisable to use the clutch anyways, decreases wear and tear.

But its Shell (World Famous Lubricants Manufacturer) which recommends that Dont always use the clutch for changing up gears.

See the URL. Its www.shell.com.

Can you please tell me what do you mean by Correct Rpm?

But the 3rd point in Clutch Control of Tips for You and Your bike (Please check the URL Specified by me in 1st Post) says that "Good clutch control saves wear and tear on your gear box". Now whats this "Good Clutch Control" mean?

A local mechanic has said the similar explanation said by raj. So I think that there shouldn't be any problem in shifting without clutch.

@sudeepd, these things vary from bike to bike. The Correct RPM should be the one at which the gear changes smoothly without any trouble. And the same goes for Clutch control too, I've seen some who slot the bike in first by holding clutch and wait for the signal even if it for a minute.

Oh!! this is really great info guys !!

Thats why i saw all MTC buesses here never uses Cluch while Upshifting, rather they use clutch only when downshifting.

I thought these guys are runing since these buses are not their propery. :)

thats the case with almost every muncipal buses across nation zinam, where they use their cluch in downshifting only, which is a common practise by their drivers.

Currently I use Clutch at the Start (Neutral to 1st) but not while up shifting after that (2nd to 3rd to 4th to 5th), but Always use Clutch while Down shifting (5th to 4th to 3rd to 2nd to 1st or Neutral as the case may be) for my Pulsar 180 DTS-i (LCD).

Feels Great while Up Shifting without Clutch. If shifted without clutch properly, no jerks are felt.

Avoiding Clutch will have POSITIVE EFFECT on Fuel Efficiency as Clutch eats up Fuel when used.

I learnt that all trucks drivers driving old trucks(that has double clutch) and most of the city bus drivers don't use clutch while upshifting. I think as they rev hard and shift, they are able to do it(like i tried in my bike- above 5000rpm). I don't know how will it be possible in cars though. Any idea on shifting without clutch in cars?

@sudeepd, it is good to hear that you don't use clutch. I tried in my bike but i'm not doing regularly. Any tips you wish to give? :)

I too didn't knew about it :!:

@CC
I try to up shift (without Clutch, of course) around 2500-3000rpm. If done at correct rpm, the bike does not give jerk and the shift action is also positive (i.e., without any Gear shifting noise).
But if not done at correct rpm, the bike may give jerk while up shifting without clutch.

I tried shifting on our Indigo XL Dicor. Sometimes the gear used to engage properly, but sometimes the gear lever made noise while moving the lever from Neutral to Third (in process of Shfting from 2nd to 3rd).
I think I will have to practise more on an open road (less traffic) first and then take it in traffic.

Also as Indigo has Dry Clutch, I am unaware of the rpm to shift.

Thanks sudeepd.
I found that it is quite easy to do in bikes but is difficult in cars. I succeeded in bringing it to neutral, but not able to engage gears.

You are Welcome. :)

I face the same problem.
I think the cars having Dry Clutch face this problem. They allow to shift to Neutral but stop from engaging gears.

Yesterday also I tried shifting from 2nd to 3rd without clutch. The Gear Lever shifted to Neutral Smoothly (without clutch) but as I tried to push the Gear Lever from Neutral to 3rd, it refused to move :shock: . Then I depressed the Clutch and Engaged 3rd Gear (from Neutral). :x

but while doin it in your car, when you hear that sound as CC and sudeep said, doesnt that harm your gear shaft where more pressure is engaged to change them unlike along with pressing the clutch, do shed more lights on this.Anjan any idea about this practice mate??

@vijay, i think it'll surely harm the gearbox. So i'm not trying after the initial failure. Will learn more and will try later.

Clutch-less Gear shifting is possible, but only in Bikes I guess.. In 4-wheelers, it can damage Gearbox..

This applies in case of Dry Clutch Vehicles.
Safari has Hydraulic Clutch. Its possible to up shift and even downshift without clutch in Safari.

@sudeepd, can you please tell me what is a dry clutch and wet clutch?

hahaha :lol!: I don't think theres any wet clutch! :lol:

It is there vibhor, i think. I've heard of it. I think some bikes have it too.

Oh, Seriously? I didn't knew that. :roll:

Yes there is a wet clutch.

Ok, Can anyone shed some light on this?

This video is very good. Please watch
