Help please 110cc vs 125cc

[denz13]

Hello my mate just bought a 125cc bike while i have only got 110cc is it worth upgrading with performance parts and tuning or buying a whole new bike when it comes down to racing?
Thanks denz13 :ride:

Throw a GPX motor in it and be done with it.

sell it

If its like our 110 my 10 yr old had, you would need to replace every part to make it race worthy. We sold it before he destroyed it trying to race it and bought a used kx 65. That thing rocks, and i only have $1300 in it with a rebuilt engine! Im not a chinese bike basher, but the py 110 is a play bike, not a race bike. :)

Well it depends, Chinese bikes vary quite a bit in quality and workman ship. Good brands are Pitster, SSR, RCM, Thumpstar. SDG(older models had 3 gear troubles). Good engines are GPX/Jiaing(sp?), Lifan, Zongschen, many upgrades available too from reputable suppliers.
