72 MPH on a China Bike!

SamM · 05-22-2007, 08:16 AM

I recently clocked a 2006 American Lifan GY-5 going 72 mph. It is owned and ridden daily by one of the posters here on this board. I was on my KTM 950 riding along side the Lifan. The KTM digital speedometer was reading 70 mph but is 2 mph off (verified by GPS). Next time we'll take the GPS and maybe hook it up on the GY-5.

Just thought I would post this and hopefully get him and others to comment on their bikes and their experiences at 70+ mph.

It's not an everyday occurrence, but it has definitely happened more times than I can count. Still running strong after 7400miles.

It's all in the gearing. A mid 40's rear sprocket and a 16 or 17 tooth front should do the trick.

Hit 70 on more than one occasion, wouldn't try to maintain that speed for long though... I'm running a 17/42 combo and am going to a smaller front soon...

by the way that 72mph was on a flat witch we don't have much up here . i hit that speed twice a day to and from work stock gearing couldn't tell ya what it is . i like it on road ,but i was trail riding with sam today and to me at least 1st gear is fine but second seemed a little to high . i was gonna let sam try it but before i could my chutch cable needed adjusted so we headed back. what a fun day.

72 is all the faster I want to go on this bike. I ordered a JT 45 tooth rear. If I can get to 70 for a short burst that will be fine with me. I am looking for a crusiable speed of 50-55 for my commute. I only take the backroads to keep off freeways.

I am only 140lbs so it should be able to still pull me off-road.

Yep, I'm weigh even less than katoranger, and I hit 50mph today on a stock 15/46 setup. I'd be very happy cruising at that speed. But 72, woooop. Is that a true 200cc, All I have is 150. It says 162 FMJ. I'd have to be falling from a plane to hit 72

shammash55 · 05-22-2007, 07:44 PM

wish i could hit that speed, must have upgrades lol.what would be the best cruzin rpms,i hit 7 at 50 on a 17/46?

Jim · 05-22-2007, 08:51 PM

Apparently I hit 135km/h yesterday.. but I am sure my speedo is acting up... sad really, been good till now, going to clean the speedo thing on the axle and re-lube the cable

SamM · 05-22-2007, 10:06 PM

I'll get a picture next time!

SamM · 05-22-2007, 10:38 PM

It's not going 72 mph in this one. Here's a pic for anyone that doubts that a china bike will go off-road. Way to go pumpkin! I was impressed with your ability and the bikes capability. I didn't get any pictures of the deep mud crossings or hopping the downed trees. Maybe next time!

Oh yeah, disregard the Yamaha in the background!

MOTOXtreme · 05-22-2007, 10:56 PM

There are 2 bikes in that picture????

pumpkin · 05-22-2007, 11:15 PM

i can't wait till sam gets his viva going so we can be on an even playing field .

AZ200cc · 05-22-2007, 11:29 PM

My cycle tops out at 50mph :( 72 is only a dream for now....... But if the bike comes apart it could be my nightmare :wink: Still nice to see these bikes can perform.

katoranger · 05-22-2007, 11:31 PM

I have had mine offroad already in the junkyard. My friend took it and his 9 year on an xr80 down some powerlines. He roosted his son with some sand. Bike had 50kms on it. Actually it first few kms were all offroad. Did a few laps around the house.

I work odd hours so it is hard to get any action shots. I am going to try and get some pictures with my friend and his kids on Saturday.
