    Recently recorded run.
    Telemetry shows I gave it gas at 100KPH.
    Bike gained 10kph for every second till it reached 150kph.
    from 100 kph to 120kph ( Highway overtaking zone) comes in only 1.6secs . damn! its as fast as just twisting that wrist.
    100 to 140 kph is achieved in just 4.1 sec. (most bikes dont make 0-60kph in that time)
    In 5.5 seconds after twisting you are looking at 150kph. that is incredible rate of accelaration for a bike weigning 270odd kg and 80kg rider.
    i Shift to Top Gear at 150kph , Although I could have carried on to 160kph in 4th itself.
    post 160 every 10 kph takes around 2 secs.
    I let go off the accelerator at around 180. Largely ran out of road.
    It was climbing 10kph at every 2 seconds at speed of 178KPH. Power is enough to top out at gearing limit at 210kph.

    If we compare it with stock times, Post 130 Stock superlow takes 2 seconds to go to 140. takes 4.5 seconds from 140 to 150 . and tops out at about 165-170kph.
    Triumph bonniville , being lighter and more powerfull takes 19.2 seconds to reach 100 to 175kph . Takes forever to hit its top speed of 178kph.
    I did 100 -175 in less than 13.8secs. 100-178 in 13.9 seconds and it was still climbing with no Remorse!

    God I am loving this torque queen.
    Usual Overtaking on highway is powering up from 80/90-KPH to 110/120kph. This transition takes only 1 sec.

    largerly as soon as you twist your wrist from 90kph , you ar looking at 120kph in an instant. almost good enough to break traction. Skoda Suberbs and Beemers and the 5 Ringed Audis just hear that fast unappologetic un forgiving Rumble when you power past them!
    Its my dream come true!

        Agree with Shreeni, you should get this great piece of engineering patented. It is annoying to see people copy paste other's property.

          OK folks!
          I am going to write a book about cruisers ( largely Harley Davidson) and focus on engineering and EFI tuning for performance.!
          Need feedback, like this post and show your interest!
          Thanks

              I know most of you are not gonna believe me! I can't myself!
              Just came back from a Sunday breakfast ride. Walked a triumph striple full throttle to full throttle ( with xaust + airbox upgrade + map- upgraded by triumph) . hit rev limiter in top gear! I guess its time to increase that rev limit with power vision.
              Little while later we stopped and Triumph rider said he was at 202 when I overtook.
              He said he was disoriented with a Superlow overtaking him at 200 .
              Strangely my bike says highest speed for today's run was 194.
              Speedo error on mine or on that triumph!

              One thing is sure , even after all those upgrades by Triumph they are no where near that 100+ bhp for sure.

                  Unreal, wow 200kph on a HD, how did you cope up with the tremendous wind blast? Did you crouch? And Triumph Striple has dual discs and abs and lots of stopping power compared to HD, how did you manage with our sporty stock brakes setup?
                  Take your HD to BIC for a run

                    Wind blast! Talk about it. My helmet wanted to leave me alone despite being strapped. Fully crouched, in fact sleeping on the tank fully with eyes barely high enough to look forward.
                    Triumph rider was not fully crouched! I mean he could do better, he was kind of leaning forward .
                    Factory 1200 with stage 1 do 200 regularly , friend has a 48 , he has done 200 many times.
                    Thankfully didn't need the brakes, triumph guy gave up as soon as getting overtaken.
                    We we started from a stand still , till about 150-160 striple had built up about 7-8 metre lead. He sort of started backing off after reaching 180 or so thinking the HD is all dead now. When I came along side him around 190 , he twisted again , but then he didn't have enough go left to blast past. We both were alongside for quite some time with me inching ahead inch by inch. Around 200 he was completely overtaken and he slowed down.

                    Will get new tyres soon and surely have a track day!

                    Point is striple is no way a 106bhp bike. I am quite sure mine makes only around 85 or so. Some of it is in the shorter gear ratios of HD but still , 100+bhp bikes don't get beaten by 85 ones for sure

                      That is great to know, HD smoking a Triumph!!! But yeah you have transformed your 883 to 1250 which contributed to this. Really interesting write up, hope someone could have videographed this feat.
                      Great going ride safe.

                        If I remember correctly Shadyabhi had mentioned he had done a top speed of 230kph on Street Triple. Could be the triple rider was not very confident at those speeds?

                        Either ways good to hear HD clocking 200 easily

                          Yes may be! Or may be he didn't have the right tune or something!
                          I felt he was not making enough power to accelerate fast enough . he still was gaining kmph , but I gained them just a whisker bit faster. Had he not given up he would have overtaken me again cuz I had hit limiter and my bike was bouncing against limiter . he gave up the fight too soon, may be though it wasn't worth fighting for, he could belt a heavy pig handler HD any day . and I agree with him if he through so. They are simply not same class of bikes, nor is the same purpose.

                          Its not about Dog in the Fight, its about Fight in the dog!
