atomik pro-x (lifan 140cc) model

[Gureno]

hey guys, i just upped the anty from my old ducar 125 (absolute heepa)

to a atomik pro-x 140 lifan

i have heard alot of rumours about these bikes, my mate upped his lifan to a 138 big bore, but we later found out after measuring that it was only a 127cc

now thier claiming thier bore and stroke is (55.5mm x 59mm) which works out to 141cc...can any tell me if these lifans are actually packing that

any overlook on these bikes would be great

note: that this is the LIFAN 140cc and not the previous ducar 140 they had in the pro-x

it kills the Ducar in my Pro X 125.

(and the dhz monster is about 10 000 000 % better bike)

so are they a genuine 140

cause i have had 2 ducar bikes now and thier a heepa, the motors are a cop out, and the chassis arnt any better

my old 1989 kx80 basha worked my ducars

so the 140 lifan is a genuine 140??

the ones DHZ and mack sell are real 140cc lifans.. the ones atomik sell the 140 so called lifans are just ducar 127cc. i got a real lifan 140 in my prox and all i can say is wooooo such a beast lolz

 

[Gureno]

are you sure your not refering to the old pro-x

because the newest one out is what i purchased with the lifan 140 big bore, and the new gearing set up, with powder coated frame, rims, forks, swingarm


as opposed to the old shit so called ducar 140 start in any gear piece of crap

From what I am led to believe is that there is no such thing as a 140cc motor. What they were calling a 140cc was actually a 138cc. The 138cc was just a 127cc. And now the 140cc are actually a 141cc.
I have been told that Braaap bikes are going to be selling there bikes as 141cc instead of 140cc so people don't assume they are the 138cc motors. How bloody confusing this is. I can understand this to a certain extent with cars, but Jeez they should call it what it is, so there would be no confusion with motors just being a bored out smaller version of a motor no one wanted.

yeh mines the lifan racing series

55.5 x 59

141cc

 

[nufc]

How can you tell? Is their a way?

 

[Gureno]

ahh u divide the number by 3.14 (pie)

i dunno my mate knows the formula

its like 59 x 3.14 x 55.5

alogn those lines

 

[forrestedge]

Gureno where did you purchase your lifan 140? I am in Perth also.... Your bike looks actually the same as my sons 150cc Torque Longshen Engine. Crap motor, gears useless so going to fit a new engine...Worth a try

 

[headsmess]

pi radius square x stroke...
diameter...59? so radius 29.5.

so 29.5 x 29.5 times 3.14 times 55.5....volume of a cylinder...sheesh

tomorrows lesson. calculating the volume of a spherical obloid

whats a sphere anyway...um....4/3xr squaredxpi...maybe
