    Congrats on your new ride..
    Don't rev your engine too hard till 1st service.. The sound you are hearing is of oil falling inside the engine since your engine gets too heated.. Its normal anyway.. don't worry...

      The sound is from the catalytic coverter cooling down.

          lmao....Oil falling... You don't know? Ayio... You see Ivin, when engine heats up the oil also heats up and turns into vapour. It then goes to the top of the engine and forms a cloud. When the engine is turned off the cloud cools down and precipitates. That's when the oil starts falling inside the engine. So simple ya. :P

              what type of theory is that? Its oil, which is been used on crank, not water. The oil pump provides oil to TDC, for lubing of valves tappets, timing chain and all. Don't say this precipitation theory to anyone.

                Hmm... while the explanation given by ABikerAtHeart is not applicable for the issue of clicking sound, it is also not entirely inaccurate. The clicking sound is due to rapidly cooling parts, especially the cat con.

                Now coming to the precipitation angle, in engines which have their cranks dipped in oil the spinning crankshaft creates a whirlwind of oil droplets inside the crankcase. While this whirlwind of droplets is used to coat the cylinder liner it also creates certain amount of drag, this drag is called 'windage'. This fine mist of oil becomes vapour due to the heat in the engine. The vapour creates pressure in the gearbox and a breather pipe is used to release this pressure.

                So while oil precipitation is not the correct answer to the issue, it is a fact of life for an IC engine which affects performance in ways that normally not even looked unless you are making a serious high performance engine.

                  i am using R15 since last three years. Have never heard any such noises. An as far as i know that tik tik sound of cooling doesn't happen on R15s like all other ic machines.

                    Really??? I thought engine oil is used to lube the drive chain.

                      New R15 owners, pls check the size of your rear tyre. Is it 140 ? or still 130 ? MRF site doesnt show the 130 revz now, instead they show 140/70/17 Zapper S for the R15, yes, the same thing that came on CBR250R in a short time.

                          Saw a new lot of R15's being unloaded at the Noida SVC a few days back, they had the same 130 section tyres for sure.
                          I hope its a mistake on their website. 130 is already a lot of tire for this bike, 140 will just ruin it.

                            Very informative reply, ty.
                            So summing this up, you are saying it is normal and nothing is there to worry about, right?

                              It is 130/70-R17 revz-s.

                                I know it is showing the revz. But select make and model on the left to Yamaha and R15 respectively and see what comes.
                                Might be a mistake.
