I own Ravi Strom / CG 125 both of em, just another 125 crazy in the block, saw this interesting thread, and thought to share some of my knowledge
Storm is faster on long roads where she gets enough time, where as CG is very very (DAMN Quick) Quick in start but red-lined earlier then storms so has a less top speed the Ravi... but the Alteration suggestions you people have discussed here are astonishing, UN fortunately both my Bikes are 2010 Model so I don't wanna ruin there original setting but I will try these all custom alteration after buying any old cheap Honda and rebuilding it ...
as it is now being a long long thread and you people may have discused already does any body happened to change the 4-speed gear box of CG 125 to 5 - speed ?? if yes what were the results?? better or worse? just a question?
