Bing, You’re almost making my point for me.

Lt250r=324lb ----------------------- 86lt250r=mid 20's hp maybe upper 20's

RM80=something like 150lb-------RM80=28hp

Now you slow down and think about it. If all those #s were correct, an lt250r would have no chance against a RM80 no less a RM125.

The weight is easy to verify so its just a question of realistic hp claims.

If a RM80 has 28hp than a RM125 would have at least 35hp maybe 40hp. If that was so, than an lt500 wouldn’t have a chance no less a nearly stock 5 speed non power valve lt250r.

Here is another way to think about it. If a RM80 produces that many hp per cc stock, than a quad motor could be modified to produce the same hp per cc on pump fuel.

RM80 28hp/80cc = 0.35hp per cc

Blaster 200cc X 0.35hp = 70hp

LT250r 250cc X 0.35hp = 87.5

Banshee 350cc X 0.35 hp = 122.5hp

LT500r 500cc X 0.35hp = 175hp

Does that sound likely to you?

 

You people are crazy to think that any 85 or 80cc bike has 28hp. They have about 18-20hp and that is a lot considering that they are so light. 80cc bikes, 125's as well have no torque whatsoever. A late model 80cc has only like 10-14 ft. lbs of torque 125's have about 20 ft. lbs and a little over 30hp.... 250's have about 30ft. lbs. and about 45 hp.... All these bikes are late model of course. The new one's are way torquier than the old because of improvements and more advanced powervalves but no way do they have near a 250's amount of torque. An 80cc wouldn't stand a chance but a 125 late model would smoke any 250cc quad. It would also eat a banshee for lunch. I saw a kid smoke a stock banshee (2000) on a lightly modded 87 cr125. 80's have such short gears as well and no low end.... they bog so bad unless you got a little light kid on them. My lt has tons of torque cause of the powervalve. I even think my modded lt could beat my stock 86 rm 125 with its .60 over wiseco and boyeseen reeds... in fact i know it can beat it (LT is modded of course and is a 92) and my 86 rm 125 is real fast. Stock (86 rm) it has like 24.3 hp and 12.7 ft. lbs. of torque. Go to[*]www.georgiaoffroad.com for dirtbike specs.

If 80's were that fast no one would ride 125's!!!

 

oh yeah it might be closebut i doubt it i ran a cr80 gainst my 400ex and i beat him not im not going to lie i didnt beat him by that much but i did beat him and our lt250r will get my 400ex anyday so i think yuoll beat him pretty bad

hey mojave300ex if you had that bad of dirt bike and you liked that kind of speed why did you get a mojave or 300ex why not jump up to a big boy bike like 400 or bigger

 

A rm 85 has about 18-20 hp stock, ltrider is correct. The newer 85s do have powervalves, and the 85 will beat my raptor for the beginning portion of the race, but the raptor will surpass it before the end of the race most of the time.

 

my friends 1996 rm80 was bored to 103 with a new wiesico engine and pro circuit silencer and bills pipe header boyesen reeds brembo bakes hinson clutch. he had it dynoed at a local shop(i know theyre all different) and it read 36 hp with 32 lb ft torque

now he has a 98 cr80 big wheel with the exact same mods and it read 38 hp with 34.7 lb ft torque

 

The Lt250R (85-86) atleast, weigh 296lbs. It says it right in the manual. Dry weight=296lbs. when ever they weight quads/bikes its dry weight. Like in cars, theyll be bragging it weighs only 3,000lbs, but when they test it its 3,400lbs.

So its 296lbs not 320+

 

hey im curious has anyone ever raced a 85-86 agaianst a powervavlved lt250r if so how much did it win by

 

but guyz a dirt bike is lighter and only has 1 wheel t spin a quad has 2 and is heavier

 

not to be cocky but my bike can usually beat any quad pretty easily.. im sure a 80 can win.. a 80 can usually smoke anything out of the hole.

 

omg you guys have have over a hundred cc's on them, you had better beat them, and if you can't use that wieght and push them in to a grove of trees...ha. I think I would shoot my self if I got beat by a 80.
