    Joel's kit worth it ??

    guys i'm in a big confusion , i have a rtr 160 2009 and im bored with its power. joel gives 170 cc kit that gives 1.5-2 bhp more for 7000 rs approx . excuse if power figures wrong as no power figures given on raceconcepts site [really weird to not display any by joel as he so believes in facts and figures]

    wouldn't it be more vfm to buy rtr 180 bore n piston to convert 160 to 180 as that costs so much less ?? what all we need to change to make rtr 160 to rtr 180 ??

    also wont it be better to buy 190 cc kit than 170cc if price is same ? i hope no fitting issues . and if not what all parts to change to make 190 cc fit on 160 .

    i would like to get some well explained answers as i don't have good knowledge in engine issues .

      An engine's cc (cubic capacity) is determined by Bore and Stroke.

      From RTR 160 to RTR 180, the bore is almost same (180 has only 0.5mm bigger bore).

      It's the stroke that has been increased by a heavier 4 mm that resulted in 160 to 180cc. Changing the stroke measurement is not possible as it will involve crankshaft modifications, which are not feasible.
      So, your 160 can't be 180cc.

      Joel's big bore kit for both 160 and 180 is the same kit, due to almost same Bore specs in both the bikes.
      And this big bore will increase your Bore only, not the stroke.

      Both 160 and 180 would be increased to 170 and 190cc respectively through the big bore kit, but stroke can't be changed.

      Joel's kits are a good long term investment. I recommend you read some other review threads here...
      Secondly, measuring power is really expensive as it involves a Dyno worth Lacs of rupees.
      Thirdly, if you want more power, get the RTR exhaust. It will increase your power and mileage both.

        Plonking the RTR 180CC bore directly on the RTR 160 is a straight NO NO. Lots of internals including the Crank are different between RTR 160 and 180.

        But TVS can completely covert your RTR 160 engine to RTR 180, but not sure about the cost. (Should be like a bomb)

        and I feel thats the reason Joel has 170CC for RTR 160 separate and 190CC for RTR 180, else he could have given both for an RTR 160 itself.

          ok so i understood rtr 180 bore is just .5 mm wider than 160 . then can the 190 cc kit be installed on 160 with compatible crankshaft and tci unit etc ? what else needed .

          anyone know exact parts to make rtr 160 to stock 180 with approx prices if possible .

            Its not about the 0.5mm extra increase in piston diameter. This is a different piston and kit altogether. Well, those who use it, please fill in.

              The bore is irrelevant here! RTR 180 has 4mm Bigger Stroke than RTR 160, and majorly that's why it is 180cc.
              And you CAN NOT change stroke because that will need a crankshaft change too...

              And a crankshaft change might require a change of crankcase too, which might turn too expensive. Better get a RTR 180 itself.

              You're trying to do this:



              Until you don't achieve a 4 mm bigger stroke, you can't make your bike 180cc and hence, Joel's Big Bore kit will make it 170cc only.For more performance, get the exhaust from Joel.

                Just a Question,

                Not sure why changing the crank case while both RTR 160 and 180 share the same Crank case??? I mean the same Part Numbers.

                  I see. I wasn't aware of that.

                  I thought the differently positioned Crankshaft in RTR 180 due to the extra 4mm in stroke might result in a new crankcase.

                  Anyways, thanks for the info.

                    Blah Blah Bleh Bleh Blooh Blooh asides... the big bore for the RTR160 is so awesome that I have an extra pair in my bed (Courtesy one Mr Gopi aka Razorblades who quit biking!)

                    The big bore in itself gives you a nice little speed bump.... and once you have tasted that, it wouldnt be long enough before you start starving and saving money for the FFE!

                      Can you be a bit detail. Like the other modds with the 170CC bore?

                      Like Porting, Cam, Exhaust Etc and also we know the Fact RTR's are Vibey in nature and how is yours after the modds and no doubt about the performance indeed.

                      Coz I have an Apache 150.

                        I dont have much technical knowledge so I will speak in layman terms.
                        The engine became very smooth. Little vibes(you need to concentrate on it to feel it) are there but not as much as it was before big bore kit. Didnt tested the bike for top speed. I had completed the run-in last week only. During run-in period I kept my bike below 6k rpm ( max speed of 80 ), driving more in a range of 60 to 70kmph.
                        My bike used to go around 85kms in reserve, after BB kit it reached 110kms first time and 105kms next time( with a mileage of 47kmpl, and that too from a 190cc engine, and that two from a 2yrs and 30k kms old bike ).
                        After servicing the service guys have tampered the air/fuel mixture setting, so will be going to Joel's tomorrow.

                          ok so i cant use 190 cc kit on 160 rtr . what about my question on all parts needed to be changed for 160 rtr 180 .

                          bore n piston [2200rs] , tci unit [800rs ] , crankshaft [??] , upjet the carb /get new one , also exhaust but exhaust i have sourced from someone who bought a ffe . what else needed and any idea on prices of these parts to make bike rtr 180

                            I don't encourage this, coz end of the day you will be paying more for the performance you gain, when compared to others.

                            Just move on to Joel's 170CC and his other stuff. coz RTR are rock solid when compared to other bikes. You can be more confident on modding than any others.

                            If you are very much interested, then I will get you the parts list soon.
