Hi Everyone
I upgraded my Panda bike with some 10inch rims and tires on my GPX 124
i noticed i wasnt getting the speed like i did on the stock 8" wheels..normaly from dead stop and take off the 8"s are really fast even on the straight away..although now with the new 10"s installed it seems like its slower the previous...could it be im still using the stock panda rear sprockets? my fronts that came with the GPX is 16teeth..i hope to hear from you all..thank you
Dave

Go to 30/31 at the rear. (your current gear ratio is good for backflips

)

I have a 13 front tooth on my original Panda engine. ....will that work with the 124 engine 10"wheels and 40 rear tooth??

You dont want to go smaller on the front sprocket, it will decrease your top speed. You want to stick with a 16/17 for the front. Buy a sprocket between 30-34T (the smaller one will give you more top speed. My 16/34 geared 125cc Lifan on 8" wheels will top out at 55mph

my x18 is running 10 in tires and the gpx pulls it fine
change up your gearing a bit and see how you like it

He said he is already geared too tall and lost acceleration. He wants the acceleration back so he would want to down in the front or up in the back. What you suggested would only make his problem worse. If he's worried about lost acceleration with a 40t rear, going to a 30t rear is not going to help him at all.

A china 124 is about torque, not revs...

Thanks guys for some feed back...Hey Pete i use to run 8" wheels and it was fast...but now with the 10 not that quick..you recomend keep the 16 fronts and get a smaller rears for the 10 wheels??

I'm running a 17/30 combination on mine. It's a bit slower than I'd like so I'm going to try a 16/30 instead. Dave, post pics of your bike up with the new wheels.
