  • Modifying my Royal Enfield Thunderbird

    Hello All !!!

    I wanted to modify my 2007 Royal Enfield Thunderbird .
    The bike is mostly in stock condition other than some mmodifications here and there ..viz.. Alloy Rims , Silencer and Horns. I have a few modifications in my mind as below :-
    • Changing the Handle Bars
    • The Front Headlight Assembly
    • The Rear Wheel .. although I am not sure whether there is any wider tyre available than the one I have got fitted. I have the MRF 19" 3.50 Tyre.
    • A Good paint job
    • Slight Modifications to the rear end of the Bike like the getting the number plate fitted slightly lower and the same with the rear trafficators.

    Please can you all advise me of any good place in Kolkata where the abovementioned Modifications can be done. Also, If any one can suggest me of any other Modifications woulld also be of great help.

    Please Help !!!

    Cheers,

    Roxan

    The Wheel was a great invention; Two Wheels with a Motor in between was even better!

        Yes brother you are absolutely correct regarding the tyre specifications. I wanted to know whether I can fit any other tyre which will be slightly wider than the 3.50X19 (without too much modifications to the rear) which is factory Fitted on the TB. The front tyre seems to be fine with the 3.25X19 .

        Any help with this and also the handle bars would be highly appreciated

          hey u r going the same way i went a year back. i got the old TB too i hv some modification to it. well for the rear tyre u can hv MRF 110-90-19 tyre but for that a little modification needed. the problem is that tyre will brush to the swing arm from left side. to fix it do as follows
          1. remove swing arm and marke the places where the tyre brush / touch the arm. then
          2. go to the local black smith and heat the arm where u r hv marked. and hit the area to make notch in the arm. the notch should be from in side.
          3. check the arm by fited tyre-rim and if need make changes.
          it seem wild but belive me it works. only all the procedure have to done under u r eyes.
          don't forget to repaint the arm in black color where u hv heated.

            And for the luck i m searching that someone can make my bikes rear end like vardenchi chopper. man i m calling all over the india and only few can do that except the Akshay varde ! one of those is Rinku from Delhi. that guy has done the 180mm with a car rim and single arm mono suspention ! like vardenchi but lack the subtle balance of bike and also hv to change the fram. well to answer i suggested him to have a jackshaft and then normal fitting. he will reply me in couple of days. If u r interested and want a 180mm tyre and rear end extrimly modified, willing to pay near about Rs 16k (INR) u can have it. i m also doing it to my TB. keep in touch i will inform u as i come to know.

                Guys is there any functional benefit of fitting a 3.5x19 tire in the rear? I have a Electra 4S which has a 3.25 as the stock tire. A friend of mine was said that 3.5s will improve stability & grip but my mechanic said that there is no difference in performance b/w 3.25 & 3.5!

                  People, there is one more thing that isnt addressed here.
                  The Handlebar.
                  I like the handlebar of my bird, but still i need slight changes.
                  Can i fit a Harley Fatboy's handlebar?
                  Where can i find that kinda handlebar in india (ofcourse other than the one harley makes, because that should be damn costly) ?

                      Re: Modifying my Royal Enfield Thunderbird

                      Hi All,
                      I am new to this forum and it is my first post. So please don't mind if i ask something that have already been discussed.
                      I have a 2015 Thunderbird 350 and i am looking for some basic modification to it.
                      1. Pillion seat is way uncomfortable and the backrest even digs in pillion lower back, so i am looking for some solution to it.
                      Like if we can change the back rest and move it a bit backward and a bit higher. Which will increase the room in pillion seat and back rest will provide better support.
                      But i looked for a solution in Karol bagh but khajanchi have some ready made seat and he is not able to support my idea.
                      So if someone have done that and could help me out with mode of modification and someone who can help me out in NCR.

                      Expert opinions are welcome.
