We seem to have circumnavigated the world for what should have been a simple discussion on the topic of finding better performing aftermarket suspension ourselves to replace OEM parts. So let me voice my concerns here one last time, lest someone take what is written on these threads as the gospel truth and tries it without knowing the possible risks.

Measure the height of your stock shocks and also compress it by putting your body weight on it. It'd give you a fair estimate of where you'd want to be.
After that simply go out looking for something that'd suit your needs, a pair of shocks cost anywhere from 1.5 to 5k depending on whether you get Gabriel or Endurance or Showa. |
It all started here. Want to replace OEM suspension? There may be cost effective options in the market, as you correctly mentioned. However, how to identify them safely while improving performance is the question which we were digging into.

So I am not able to understand, is there is way to know what you are actually getting when you look at 5 options in front of you? Or just pick which one is closest to the dimensions of the OEM exhaust and try your luck? And then work through your options till you find one that works? |
Simple enough question right?

Since we have the recommended numbers at hand the next thing that needs to be done is remove the stock shock from the motorcycle, measure it and then put load on it to gauge compression.
Once you're done just go to your nearest showroom or spares shop and find a suitable match.
Length is the most obvious factor and once you have found a lengthwise match next you put load on it, use your body weight. It would give you a relative idea of compression.
Once you find a suitable match you can buy a pair and install them. After installation you could get the tape measure out again and measure your static sag and free sag and compare it to recommended specs if you're doubtful of yourself to be certain. |
In simplest terms, a suspension needs to have compression and rebound. I fully understand what you are doing which is why I mentioned that its not scientific. To recap,
1. You remove the existing suspension.
2. Then you put pressure on it.
3. You memorize how much pressure you put.
4. Your body "measures" the compression and rebound separately based on how much pressure you put on it.
5. You memorize the compression and rebound.
6. You got to a parts store.
7. You ask for suspension similar in length to what you already own.
8. You recall the pressure that you put in step 2 so that it can be duplicated.
9. You recall the compression and rebound that you memorized in step 5.
10. Then you start testing the multiple options in front of you by putting the same pressure as you recalled in step 8.
11. You decide which is best.
12. You try and see if it works, else go back to step 2 and repeat.
If I take a car analogy, suppose I want to replace the suspension of my Honda Jazz. I do steps 1 - 5 and then go to the parts store. I tell the store guy show me what suspensions you have in similar sizes and he shows me suspension of the Alto, Kwid, JTP Tiago and XUV 300 all of which are around the same size. I then follow steps 7 to 12.
Anyways, as I said, if you feel this is scientific and it works for you, all power to you.
Well there are other impacts to the motorcycle when you change the height of the suspension as you had stated below.

So it isnt as simple as swapping out one suspension for the other from a different manufacturer / OEM supplier. There are much more things to keep in mind. BTW what happened to the squat thread that you mentioned? I went back to reference it and jog my memory but I noticed that some points from Sutripta and nitro.1000bhp were brought up by there was no response and eventually, nothing useful came out of the thread. Hope you can reply to them there and continue the discussion on that, so we can all learn.

I do believe that you are mistaken while making some of these sweeping statements regarding paying a fair amount for a product or an offering that has been tested by after market specialists, whether they are in India or abroad. Why so much negativity against the professional aftermarket industry? If companies and enthusiasts are spending their time and money on R&D and extensive road testing and offering suitable products to improve stock parts safely, why unnecessarily throw shade on them? How are we predetermining that what they offer will be shoddy? Or that they are just praying for their parts to work?
Lets come to the fraction of a cost aspect as well. Lets assume a pair of rear suspension costs an average of Rs 3,500. Now since its all trial and error, for the sake of our discussion, lets assume that we need to go through a say 3 pairs to find something that may be comparable or better (
if we are lucky) to the OEM suspension. So keeping aside the time and labour costs, that in itself is Rs 10,500 for the parts alone. Then you add up the proper road testing and time required for each option that you try.
Im not discounting the possibility of better parts being available in the market that maybe an upgrade to what you or I have on our motorcycles. But to make a blanket statement that everything aftermarket will be shoddy and that anything trial and error will be super cheap and better, is misleading at best.
To those who may be new to this and want to improve the suspension of your motorcycle, I would suggest that you dont just blindly follow the trial and error process if you are not an expert and get something proven instead that fits your budget.
