yer but the specs arent always actual facts cuz they bullshit to get pplo to buy them

 

[no_crf50_here]

I'll go the XY140 as i'm running one atm in my motard, tuned rite they are a little power house..

 

[wogtaz ryder]

i havnt really ridden much of the 125 but ive ridden on a main road to a mates house with another mate on a 125 and he was same speed if not faster flat out! and ive ridden one around the track with me bro on his 140 and it keeps up with acceleration .. hmmmm

 

[pickles09]

lifan 140 goes hard with an inner rotor

 

[Panda_ET]

yep tested this a few months back lifan 125 vs lifan 140cclighter rider on the 125 and still the 140 left it for dead there was no question

 

[themountain]

all stock...the yx wins !!

 

[aiiDz21]

my mates stock lifan 125 beats mi stock lifan 140 in straight line

 

[pickles09]

wat 140 is it?

 

[sus1]

well my yx140 and terrys yx140 beat yx150s in a strait line... thats cuz hes the worse rider ever lol

 

[rainey]

no way is the 140 quicker than the 150...............the 150 is so quick everywhere.down low , up top, mid range...............the 140 with the irk can keep up for maybe 20 metres then the 150 just flys

125's have alot of potential and can easily be as quick as a 140with the right tuning and a bit of porting.......... noticibally

 

[themountain]

my mates stock lifan 125 beats mi stock lifan 140 in straight line

[sloth_fmx]

[Pitst3r X4]

yep cause the 150 rider has to be the best rider ever just cause other people are jealous (and think they're better than chad reed cause they know how to thrash the hell out of a bike ahhahahahahah)

 

[themountain]

[infiddy]

dont matter what you ride, ive seen people down the creek xr100 vs 125cc thumpstar's and motoverts beat xr100's, stock motovert 110cc riding really hard to keep up with a kx85 and they wernt to cloose btu cloose enuf for a good show. if you can ride, youll beat anyone regardls 125cc or 140cc or yx140 what ever that bullshit is

 

[Irvo125]

I agree with Infiddy, there. I run a 125 lifan with with IRK, and monster valve head. no lightened oil slinger as its all up gearing. Not pissing in my own pocket but i beat the 140XR bikes at torrens island as well as two blokes on those pitpro 250cc big bikes. I've riden a 140s and went back to the 125 i find them more fun and zippy through tracks. they make things fun when you have to rev the guts out of them through berms and along the flats. good fun. I am biulding a new bike now which will be a 125 again. love it. Haven;t raced sus1 out on the tracks yet but im keen to give it a go. lol
