      that's a pretty large error of nearly 8-10 %

      anyone knows for sure (via some definitive measurements) if the speedo errors in bikes are so large throughout the speed spectrum, or only when a bike is nearing its top speeding capability ? i mean when my speedo shows, say, 100 or 120 or 130, does that mean there's 8-10 % error in that speed too (in which case when the speedo is showing 120 i am actually doing about 110 or so) ? i have not been able to find out the answer to this question with surity, BUT based on several average speed measurements that i have done on that empty expressway near my city, it seems when it show 120 for instance it really is doing pretty much 120...so based on that so far i believe at those kind of speeds (say 80 % of the possible top speed) the speedo seems to be accurate enough... dont know how its accuracy precisely goes down as it nears and crosses 130-135 (on the speedo) or so...someone else is needed to make a large set of measurements of all kinds while i am ripping the bike on that expressway...

        yes. most bikes have speedo errors. nothing new in that.

        R15 has 9% approx speedo error. it varies from 5 to 9%. i remember abhishek sarcar telling me that when he was doing 100 kmph with the vbox in the bike, the vbox showed around 94kmph. so as the speed increased the error increased.

          no i knew that bikes have speedo errors, but didnt know it can be as large as nearly 10 % even in today's technology...5 % or so i thought was the worst case scenario (like when approaching top speed)...but according to that vbox reading of your friend, just at 100 kmph (speedo) it's already 5-6 %

            Speed can also be checked using gps. If you have gps enabled phone get an speedometer app put the phn in your pocket and go for it. It records highest speed atained. I have not tried it but concerned people can.

              vbox too is a GPS based data logger.

              good idea but dont even know if my phone is GPS enabled

                Speedometer - Wikipedia, the free encyclopedia

                for better understanding. there is a small para on error. ". Vehicle manufacturers usually calibrate speedometers to read high by an amount equal to the average error, to ensure that their speedometers never indicate a lower speed than the actual speed of the vehicle, to ensure they are not liable for drivers violating speed limits".

                for everything else there is "google".

                not necessarily. even the gps in phones are not very accurate. they work of the nearest signal towers and its takes some time for those devices to get the proper reading. so cant trust them. i had got top of 145kmph on gps and i was doing 152kmph. and also i have got 134kmph, 140kmph too. the conditions were different in each riding. heavy breeze or less breeze etc etc.

                  10% is the permissible speedo error limit. The real R15 top speed is reported to be 135kmph whereas speedo indicates a little over 150kmph.

                    Hi,
                    Some basics are missing with the top speed spectrum, rider with less weight can reach high speed soon and also gets more top end numbers in comparison with heavy riders on same bike.

                    My weight is 84, i did went upto 145km/h and my friend goes sooner and achieve more high end speed.

                    That is why i do not win the drag race with my friend as he is best as me in riding skills and weights 45. ;-)

                    Ron syle is right about the GPS on mobile which depends on network, i checked the speed difference on my windows phone App,
                    When i was at 54km/h on my Bike, mobile showed 49km/h and when the network tower changes, the mobile speedometer hangs for sometime.

                      that's clever actually. with that reason plus all kinds of physical factors playing their roles when one is riding a bike, i guess 10 % is reasonable albeit a bit large an error margin.

                      error of course increases and nears its max when one is top speeding and gradually approaching the bike's max speed capability (say post 130-135 on the speedo)...there i am sure it's pretty much 10 %..but in the range 90-120 or so i guess it's no more than 5% usually.

                      anyway..it's the mind's perception of being in high speed or acceleration that matters most as that is what we feel...the actual value of the speed is just a number for measurement purposes...

                        btw had second service today, at 2530 or so kms on the odo...they didnt even wash it all that properly, and polishing was worse...but as long as it's not looking too dirty and uncared for i dont mind, so didnt bother to say anything about it...

                        am soon sticking a rim tape on my wheels, but unable to decide what colour would suit the most - blue or green..any suggestions from people with vivid graphical sense ? blue would seem to be an obvious one, but then green also seems pretty nice looking in my mind...red or yellow tape surely too funky on a racing blue R15.

                          Inknow that the ASC are irresponsible when it comes to washing and polishing of bike. All you can do is order them to work on your bike and pay like 20-50 bugs.
                          Rim tape blue looks decent and good.

                            Took delivery of my Thundering Green R15 today and Im very excited. Did a thorough pdi before taking delivery. Took it for a spin to ensure everything was proper. Then rode off home. The ride is super smooth and attracted quite a few heads on the way Filled up the tires with nitrogen as well. Will be doing a more detailed review once I complete the run in. Currently Im babying the bike sadly I forgot to take pics in all the excitement

                                You can also fill it up with nitrogen. The pressure lasts longer. I filled it up at Bridgestone for Rs.60
