Yes my bike is all stock with no mods of any sort. The reason I think I can go that fast is because I only wiegh 135lbs and take really good care of my bike.

I tested my two bikes using a truck driving next to the bike while it was topped out. My panterra 90 (86cc version) top out about 53mph, my custom Panterra 50 (88cc bored motor) did 61mph, the bikes with a little modification can go pretty fast.

The bike just doesnt have a bore kit on it. I have been building little Honda horizontal engines for over 10 years now and know how to make them fast. It has numerous hours of work on it and engine hop-ups I do not talk about because if you are not careful doing them your motor will go POP and die. I will admit riding next to a truck isnt the most acurate way to tell speed but its the best I could do, and it was within that speed give or take a few MPH.

yea it might but thats almost to fast to believe

Reply by superhondaz50 on 11/14/2005 08:01:21 AM
What year(s) are your 80's? they should be alot faster than that

Reply by kag16 on 12/13/2005 07:26:26 AM
my friends 80-85s are 1995-2003 there are about five of them and they still top from 65 to 70 MPH

I believe him I know it can go about that fast. I too have been building these little motors for a long time, they're so simple to work on but with a little modification u can get a lot more from them. I know mine hits at least 50, the stock bike can't even keep up with mine. You wouldn't believe the difference on the panterra 49cc when u do a rear suspension mod. Mine sits 4 to 5 inches higher in the back than the stock bike. Although it requires a heavy duty swing arm guard. It hooks up with the ground so much more and gives it a higher top speed. Tinkering with the carb and adjusting the jetting also gives more top speed when u put in a better air filter. Also oil weight will change the way the motor runs. I run twice the weight of the recommended oil and have a smoother and faster bike no adverse affects at all. Not even in 30 degree weather. Still cranks 1st try every time since the rebuild six months ago. A little love and care go a long way with these bikes. (By the way the valve gaps suck on these bikes many of them come from the factor with loose valve nuts. Remember a little lifter noise is a good thing. No noise means no compression.)
