replace the bolts with better quality ones, 1/4 throtle, mini pro tapers, re-enforce frame, new chain (sooner or later it will snap), chunky tires when you neeed to replace and maby a different sprocket set up
gripper seat and high foam base
i personaly thing these do not increase its performance... if you want a bang for buck... i would sujest going 16t front and 34t rear... this will increase the speed off ur bike, but and will have a large affect on 1st gear... but the question is, do you want the bike to make more power? last longer? or go faster?
if its all 3 id do everything that have been mentioned previously...
also what kind off bike are you running?
just wondering whether any one here has a complete stock 125cc chinese import and whether they know what its top sped is without any mods on the bike
I would agree with this. Maybe a bit faster down hills. Haven't actually got a speed reading on mine but it seems around 70.
What advantage does a new air filter give you from the stock ones that come with Atomiks?
ie. sound better, look better, power?
