Re: Hero Karizma ZMR (2014 version)
Upto 4th gear it is possible to touch rev limiter RPM..if you want to touch 9~9.5 K RPM on 5th you have to overbore to 67mm and increase power...Mr.Arun aka ACS had done it, but I don't think he had touched the rev limiter RPM on 5th..Otherwise going 3 tooth more on rear sprocket or 1 tooth less on front sprocket will enable you to touch 9 K Rpm on 5th.

Re: Hero Karizma ZMR (2014 version)
Divya Sharan.....just like Sibun Ji said, the new configuration of ZMA/ZMR makes it produce 2.5 Bhp more which helps the bike to reach higher top speeds. The Electronic Rev limiter for both model is set approximately at 9~9.5 K RPM. While the older engine can not reach it (except Downhill) the top speed was limited...Leave a comment:
