yes the 125 with the 80 frame is goin to go a little bit faster because it is light it probaly feels like it has more torque too because it will pop up wheelies faster but probaly the 125 with the cr 80 frame.
an 80cc to a 125cc depending on how much you weigh.
how much engine oil goes in an 80cc dirt bike
it depends, what brand is it
a 125cc motorbike
Kawasaki is the best 125cc dirt bike. Hopefully this link will helps you.
a 125cc pit / stomp bike can reach limits of 70mph :)
In my opinion NO. An 80cc would be a good start. 125cc if the rider is experienced. If its a four stroke and he/she is experienced enough to know his limitations I would proceed with caution.
im not sure about that but i can say that a 2 stroke 125cc is faster than a 125cc 4 stroke and probably 200cc too. a 125cc 2 stroke would throw you off the back if you cant handle it properly, where as the 4 stroke wouldn't scare the living daylights out of you
the 140cc can reach speeds of up to 160km/h where the 125cc can only reach a maxium of 100km/h. this does depend on weight though.
I have a Yamaha 80cc with frame number and matching engine number: G3 116632. I believe this is a european bike because the spedo is in Klm,s and the year is 1964
no i cant turn a 50cc pitbike into a 125cc pit bike the bike will blow up .
about 60mph
