gpx160 or pitsterpro 155z?

[killa pitpro]

which is a better engine the gpx160 or the 155z? and do they fit in a klx 110 frame?

 

[wogtaz ryder]

They will fit a klx "china" frame , not a Genuine klx frame ..

And they both go alright take your pick.

I would go the 155

 

[no_crf50_here]

I've been told they are the same motor?

 

[killa pitpro]

alright thanx for the help guys

 

[wogtaz ryder]

I've been told they are the same motor?

Nar they are different bottom ends , dont have a clue how...

They got thicker cases

and the head is a different design..

Thats all i no tho

 

[nicko451]

any idea on power differences??

 

[wogtaz ryder]

Wouldnt be all that much ..

They say the 155 will run with the 160 easy because of the different head design and the 155z has more compression , piston goes up 1mm more on tdc .

I have been told by Ken at DHZ that the 155z is overtaking the GPX160 and soon they will no longer sell the GPX 160 as the 155z is streets ahead.

I own a 155z and cant complain, same as wogtaz
