like get 1 or the other?? how much wood the 39 rear make it go faster??

a 125cc would probs hit like 70km/h.. with the sprocket maybe 80.. but yeh a bit like 15% more..

so puting a 39 rear wood go like 80 but wat about a 37??? or they shit cuz they loose power in taking off and shit??

is 17f and 37r, go good with taking off fast and have a top speed of jst ova 80?? even 90?? and still wood have to change the chain ???

i was running 16 37 and i hookd u a speedo and it rekond 94kmh but duno if i set it right or not
