Fastest Bike!

i got an x14 all stock it tops out at about 63 i just tweekd with the carb.

Right I have one that is compleatly stock and It even says in the book that the top speed is actually 75kmh which is honestly only 45mph and I took mine out and that about all I could get it too do, with mods I bet it will do 60 65 but not "out of the box"

i got sum cheap pocket bike that can do about 45mph 40mm piston made mods on it myself.. smaller rear sprocket... ported crab... ngk plug.. stage 3 reed.. i make my own fuel mix... went through 5 pairs of piston rings..

I have a X-18 that hit 45 right out of the box. from venom motors No mods.
Its not the fastest but its a hand full.
I raced with a big midibike 110cc 3 valve(the biggest in the market) and I kept up with him until fourth gear.

This is a good bike but it takes a long time to get out of 3rd gear.

my x-18 has gotten up to around 48mph, but then again, i was riding it in a neighborhood with turns, and was unable to top out. so i guess it would hit around 50-53mph? but hell yes! i love that bike, i've been riding it naked for some time now (without the fairings, dont get any ideas. but that would be fun....) and x7rocks, i agree with you when you said that 1rst gear sucks, i think i toped out at around 15mph in first, i can run that fast!, but its useful when pulling wheelies. what do you think the best mod would be for my bike without costing over $150, and giving me lots of speed?

a front 18 sprocket
topend and all that is really determined on the gearing motor just helps top them out guicker in my opinion

79mph on my 140cc monster heheh bet could get over 80 down a hill
