80-90-100MPH is this for real?

TheBrainII · 06-11-2007, 09:31 AM

When I started looking at getting one these bikes (gy-5) I found most places listed the specs and a top speed form 60-65mph. Now I'm seeing a few places advertise them at 75, 80 or even 90mph top speed. I even saw one seller on ebay ad say "about 100mph" for a LF200. Something tells me this is pretty much impossible on these bikes no matter how it's geared. Is it possible the new OHC motor has a little more top end, and when they get going down hill in a tornado, drafting a truck, running 103oct. and NOX, with a midget driving, they might get close to 75?

Sure with enough gearing and the right conditions, you could get to 75. But.... why would you want to? These bikes cruise well at 55 mph. They are NOT Interstate bikes, nor are they MX bikes either. They are a good commuter / trail bike and that's what they were designed to be.

Dad and I have been 75 with only the standard mods and I'm pretty sure I'm not a midget, unless there's another class of midget somewhere in the 5'11" 265lb range.

pumpkin has had his American Lifan GY-5 to 72mph. I was beside him on my KTM checking his speed. With different gearing I'm sure 80mph and maybe a bit more is possible. I don't know about 90? Doubtful!

jkomp316 · 06-11-2007, 11:20 AM

you guys are crazy, the brakes aren't good enough to stop well at 60mph much less 75...

Agreed. These aren't sportbikes, and they aren't meant to be.

We really need a china bike get-together and we'll end this nonsense once and for all at the drag strip.

So does anyone know of a flat or slightly down hill road/trail/field about 3/4 of a mile long that has a prevailing tailwind?

We only need to have to different classes, one with the "cool boy" stickers and one without.(cause we all know the "cool boy" stickered bikes go faster)

AZ200cc · 06-11-2007, 12:53 PM

This should do the trick...Now all we would need are 100mph winds.

SamM · 06-11-2007, 01:49 PM

Now you're talkin'!

China bike drag races! Yeah!

red2003 · 06-11-2007, 01:55 PM

Somebody call Rich Christianson.

frostbite · 06-11-2007, 02:07 PM

Somebody call an ambulance.

Hey I resemble that remark

You know though, I've found the brakes to be pretty good for a bike that's definitely not a sport bike. I've even pulled a few stoppies just to show Dad what a stoppy was. :roll: Maybe the street rubber helps with the confidence in braking, but I rode the same with the old knobbies too.

street tires would make a big difference. i guess... im used to riding sportbikes. its hard to have confidence in something that costs so little. i'm just amazed it still starts and runs.

fatboy250 · 06-11-2007, 03:05 PM

Yeah I guess it won't be too long before Discovery Channel comes a callin' on me and Dad.

Did any one see this episode? A 250cc two stroke breaking the top speed record going something like 129mph??

AZ200cc · 06-11-2007, 03:08 PM

Does make You wonder who has the fastest DS on the site though :?
