went riding today...rode pretty hard. My buddy (gpx150) and I (gpx160) practiced some starts. He got me out of the whole like 5 out of 6. His bikes definatley revs faster. Hes got like half a bike length up into 3rd gear. He's also 30 /40 lbs lighter. I'm putting on a 177BBK with a V2 and a 28 Tb carb. Things better be different next weekend

Need more info about the bikes? I would drop the 150 in the lake as a boat anchor if offered both. in the same bike, same rider, the 160 is better all around, the only way the 150 would pull harder in a short run is if it has an inner rotor. same flywheel the 160 is king, also the 160 has better cases and crank.

I gotta go do some ab crunches

RLucky82 · 10-05-2008, 08:25 PM

LOL at least your honest.

CJsDad · 10-05-2008, 08:27 PM

My son has a 160 in his Pitster and I think it revs faster then his 150. It also has a lot more off the bottom.

Wandell · 10-05-2008, 09:38 PM

Just curious, what are the HP ratings of the 140, 150 and 160?

I'd like to know that too....I'm considering upgrading my 125 and don't know what I want to do. Cheap route and pick up the 140 so I can use my exhaust/skidplate or go all out for the 150 or 160.

chump · 10-06-2008, 07:41 AM

did you swap bikes? Maybe his technique is better? Gearing? Tires?

stevos50nuts · 10-06-2008, 12:39 PM

no..didn't swap bikes..probably should have. Gotta be the weight, right? Another observation, his tire has some definate wear on it and mine was day 1 on a Dunlop 756. Seems like he could dump it and get more wheel spin than front end lifting.

Its the weight if there both stock

I know first hand its a pretty big deal....My buddy and I both run 125 Jialing/GPX's, I have a 12" rear he has a 10" rear. He still pulls away from me on long straights due to me being about 50 pounds heavier than him.

I think my engine is even tuned better than his

gotta hit the tony little gazelle some more.

stevo you need to switch to light beer when your riding man....... cut down on those calories

boonacka · 10-06-2008, 02:20 PM

NCC · 10-06-2008, 02:47 PM

I know Hack has mentioned the 160 doesn't seem to lunch cranks like the 150, this is the first I'm hearing of case differences. Can you point out any specific changes?

357 Racing · 10-06-2008, 04:32 PM

Ya I didnt know they where different.

RLucky82 · 10-06-2008, 05:25 PM

sams 160 cases lasted about 1 hour this weekend. ...40 lbs is a huge advantage on a 12hp engine!!!

Wandell · 10-06-2008, 05:32 PM

Anyone know what hp the three engines are rated at?

HACKMUNCH · 10-06-2008, 05:34 PM

160 cranks are good, 150 cranks suck, both cases have issues.

as Hack said, they both have case issues, but the 160 is the next step in the evolution,the webbing is thicker. in the near future you will see both the 150,160, and new 170 with very strong and improved cases ,with almost all issues addressed.
