CBR 125 Sprocket Help?


Recommended Posts

Hi guys, WonderAve here with a question for the gearingly gifted of you.

As I need to replace my chain very soon I was thinking I would go ahead and do the sprockets too. A 2 birds with one stone kind of thing. Then I thought, the little CBR does struggle with the hills and wind and whatnot. Plus i've had it absolutely maxed more times than I care to mention, thinking "I want more". I can't upgrade to a bigger bike for around 18 months yet as I'm 17 so I was thinking about customising the sprocket setup. I was thinking a straight lose one on the rear and gain one on the front. Any thoughts as to how this would affect speed etc? If I got 10mph top end speed increase how would this hinder the acceleration? Also, any ideas on cost? Thanks in advance.
