  • Parts quality on superbikes.

    I am a new entrant to the world of big bikes, while mine is not a supersport or a litre class but I presume a ninja 650 , 2017 qualifies as a big bike.

    So , I got the bike and obviously the requests for photographs and test rides start. And as bad luck would have it (my landlord calls it bad Drishti, for not taking the bike to a temple before riding it), my friend dropped the bike from standstill.

    The rider was on his feet but could not handle the weight, dropped it when the bike was at standstill, the brake levers and the rear footpeg on the right side just broke.

    It has put me in a bad mood, confused and depressed I want to get opinions from other bikers..
    Can a fall from standstill make your bike unrideable?
    Some observations from my side..

    1.During a fall the pressure on brake lever is max at the point where it touches the master cylinder. I would not be so cross if the lever broke in two and I could operate it with 1 finger atleast.

    2. Rearsets just fell off. When I see them I see the same material as the brake lever, i mean..They take more stress than a brake lever , so why the same material?
    Also, the thickness on the footpeg holder is less than that of brake lever.

    I understand the fact that a bike takes damages when it falls.. but are they so significant that they make your bike unrideable?
    I once went down on a Honda at 80kmph, the footpeg were grinding against tarmac at that speed and were the ones which brought the bike to a stop.I just picked the bike up and went home, no problems, had to replace the fairing and stuff but I was not helpless.

    This drop was at a standstill..And considering the bike was meant as a sports tourer, is this quality standard acceptable?

    Is it same on all big bikes? Is this how living with a SuperBike looks like?Should I expect more such instances?



    These hold your footpeg, which has to take care of the weight of the rider . Full weight if he decides to stand on it. An Android charger for size comparison. The thickness is same as a polo candy.




    Brake lever breaks from the base. And it looks much more sturdier than the brake lever.

    The extra weight of a big bike means that even at standstill you can incur damage which otherwise is unimaginable on a small capacity bike. Also, there are times when you can get unlucky and have some part of your bike hit a protrusion on the ground.

    There are manufacturers and aftermarket part makers who build foldable pegs and levers, which fold on impact rather than snap off.

    Take this as a positive and learn from it. We all learn from our mistakes after all! It's your motorcycle, don't give it to anyone
    Biking is not about what you have between your legs, its all about how well you use it!!!!!!!

        Re: Parts quality on superbikes.

        My 2 paise :

        Don't give out the bike to people with no sbk experience. Politely decline.

        You lose with religion either way : if you did go to the temple/mosque/church for God's blessings, and meet with the same accident, they would say - due to the religious offerings the impact of the accident is reduced, and you must offer another service to God to prevent more accidents in future. If you get run over by a KSRTC or BEST missile, they'll say - his time has come, God took him, or else, he has some sins in the past life that he suffered like this. I have first hand experience of this.

        I heard that the new 650 has some weight reduction. Perhaps they involve using lighter components which are more fragile? Just a hunch, haven't seen the new 650 in the flesh yet.

          Have a look at the picture.. this is not steel, some form an alloy. The two curved parts are the one that hold the footpeg in place on either side of the bike.

          I have my android charger pin for a perspective on size.
          I won't judge the strength of the metal by its size but , this thing broke off when I was moving the bike backwards and hit a metal gate at like 1kmph or slower.

            That's shocking. If the pegs break off if you hit a gate then the Kawasaki's aren't for people like me. Ive dropped my little cbr 250 more than six times, and I enter most gates by ramming it with the front wheel just hard enough for it to swing open.

            Put up this picture in the global forums. Let the word get out that the customers don't like the bits of their bike breaking off so easily. Perhaps Kawasaki would issue a recall of the weak parts.

            What if you were riding at speed and taken unawares by a speed bump, and you have to stand up on the bike to take it, and due to the impact one the footpegs break off?

            You could easily lose balance and become roadkill.

              [MENTION=58594]leech[/MENTION] Do you really expect someone to be able to stand and ride a sport bike, even to be able to hold the handle bar! Hmmm.

              @ArunMKumar I have seen similar thing happen with Duke too. Alloys are used because they usually bend or break away to absorb the impact of fall. I always carry both levers (left&right)on my trips.
              P.S: God has got nothing to do with your friend dropping the bike. Just buy new levers, they wont cost much, and don't give the bike to people who cant handle it. You are risking their life and your bike.

                Hey pranjnyan, let's set god aside for a moment.. now that the puja and stuff has been done [emoji5]

                As for the parts, yes.. brake lever was crucial, so I got one of my friends ship it from Pune after purchase from service centre there, and I fixed it myself.. not a difficult task. The brake levers are around 3500 per piece.

                Lesson learnt.. not to give the bike to anybody no matter how much they request or try to emotionally blackmail me.[emoji1]

                I have initiated an insurance claim from my side, let's see how things go..

                The other part that I wanted to ask was, the pegs are foldable so that they don't wash away in the event of a crash , I get this point but if the peg holders don't hold up, then foldable pegs don't really mean much. This is how I look at this situation. What do you think about this?

                  This may be a one off scenario or a real wierd fall for all I know.. but still I would like to know the opinions of long time SuperBike owners about their take on this thing. Thanks for this.

                    [MENTION=44701]prajnyan[/MENTION] - what I meant by 'stand' is raising your butt off the seat when you get close to the bumps so that the shock doesn't hurt your spine. Doing this transfers your body weight to the footpegs.

                      A part is designed to take a load in a certain expected manner.

                      A gate for example will last a lifetime, being open and shut, even slammed shut. But you see children hanging off the gate while playing and the hinges will get loose and the gate will get warped in a matter of days.

                      On a cycle the ultra-thin chainstays can take crazy amounts of load of the power being put out by the rider. Luggage being carried on the rear wheel. Big bumps and drops while taking jumps. Nothing will happen to it. Yet if you tighten a kickstand onto it, it can snap off in seconds!

                      A footpeg is designed to take the weight of the rider when he is sitting/ standing on the motorcycle. The direction of force is very different when crashing.

                      In the example of the cycle chainstays above, the chainstays can be made much bigger, thicker and bulkier so that it doesn't snap with the kickstand. But that will come with a weight and volume penalty.

                      When you are trying to save weight, this will always be the case. It will be designed to take a load of punishment in the course of regular usage. But force applied out of the ordinary can cause far more damage than it would appear logical.
                      Biking is not about what you have between your legs, its all about how well you use it!!!!!!!

                        Great points there Avinash. Just to add to it, modern cars and bikes have crumple zones and parts. Which absorb the impact and disintegrate in order to save the occupant and other parts from damaging. If in this case the alloy levers and holders didn't break, they could have transferred the impact force to other components. In this case, the other components are safe.

                        See, if you are in an ambassador and you hit another car at 25 kmph, the Amby won't even show damage, but it would transfer all the energy to the cabin. It can be disastrous. Now, do the same in a Toyota Etios. The thing would crumble like crazy. Doesn't mean Toyota is cutting costs. It's working as per design. Yes, it hurts to see your bike fall but be glad it's nothing big.

                        Just get foldable levers and add some cool factor to your bike. Ride safe and never lend it to anyone.

                        Cheers!
