No problem and thanks for watching... I'm glad to help
Hi. Firstly thanks for your effort making this video. Just want to ask, did you try changing only 1 sprocket at a time after this video? Not sure if you notice, the top speed 162KMh achieved with 15-45 setup was at below 10k RPM which seems to me, you dropped the ratio too much than the engine can handle. If you still interested to conduct the experiment, I would suggest gradually change the sprocket starting from 14-45 to 15-46 as increasing 1 tooth in front is equivalent to 2 rear tooth.

Yeah bro... I just conduct the test with 1 sprocket 15-45 in this video. And I appreciate your advice not to deviate too much from the stock setting... Perhaps 14-45 or 15-46 would provides better performance but I never tried yet... And thanks for watching

Please share the result if you happen to do it in the future. I'm curious how Duke 250 will behave with some tweak to sprocket but living in apartment, it's quite a hassle to experiment by myself.

Hi bro...when you put 15-45, does it become more smooth in acceleration? My wife doesn’t like when riding Duke with me, she get smashed to behind because the torque.

No bro... The pulling force is still very strong even though ratio has dropped but that minor difference will not cause much effect as the sprint time and top speed is still the same

Mestilah boss... Sebab ketinggian tayar blh mengurangkan top speed... Saiz tayar 160/60 ialah saiz lebar 160mm dn profile 60 maksudnya dinding tayar ialah 60% dari lebar tayar iaitu 96mm... Jumlah keseluruhan tayar akan menjadi 96mm x 2 tambah rim 17" yang sgt tinggi... Jika original size 150/60 ialah 150mm dn 60% iaitu dinding 90mm sj... Jumlah keseluruhan 90mm x 2 tambah rim 17" pun rendah... Jadi enjin pun akan rasa ringan untuk memusing tayar yg kecil... Top speed pun tinggi

Yup. I do agree 15T is too big... 14T for front should be enough... should only do adjustment on the rear sprocket...

bro sprocket doesnt help for top speed .... its already been fixed top speed in the ECU..... for the top speed we need to remap the ECU or change the stock ECU with other ECU ( powertronic) check the video about powertronic ecu

For better sprint then you can choose 14-46... It provides more torque for acceleration

У меня передняя звезда стоит 13 зубьев, а задняя 52. А как в стоке было? Я покупал мотоцикл не новым. Может прежний хозяин так установил.
@MichaelLee26

Я думаю, что предыдущий владелец хотел лучшего ускорения, потому что передаточное число 52/13 составляет 4,00, что за каждый 1 оборот передней звездочки будет вращать заднее колесо 4 раза, что очень много, но пожертвует максимальной скоростью... Держу пари, что вы скоро достигнете максимальной скорости, пока двигатель будет подпрыгивать
