An 80cc Yamaha raptor typically has 3.5 horsepower
the 80cc kit is for a faster run
from 80cc to 750cc
If you only use one piston ring on 80cc bike engine, the compression ration will be reduced.
There is not a direct answer to your question due to you are asking about engine size/displacement. The amount of "work" an engine can accomplish is related to the torque that is output from an engine. The amount of torque an 80cc engine can produce is also variable. For example, a screaming 2 stroke run at 12,000 rpm does not have much torque -- it relies on the engine momentum to do work. A 4 stroke 80cc engine would have more "torque" (but less horsepower) There is also a gearbox you have to include. A large reduction gearbox that turns slow for the high engine rpm could output hundreds of pounds of torque (foot pounds or pound feet) translating to pushing thousands of pounds.
A moped will carry a 300 pound person, an 80cc or a 125 cc moped will manage, but will be very slow in climbing and the secondary transmission anb rear shocks will fail in time, I would advise a scooter, a 400cc burgman, it`s basically a scooter on steroids, 400cc automatic and is designed for two adults, it will easily cope with a 300 pound adult.

I have the same problem with mine. 2003 raptor 80 with 40hrs on it!!
80cc is the size of the piston (bore and stroke) and has little to do with horsepower. There are 80cc engines that only output 4 or 5 horsepower. There are racing 80cc engines that run on alcohol or methanol and output 20 horsepower.
Yes. Trials Yamaha 80cc.
Its a pw 80cc yamaha dirtbike
nope just written awnsers sorry :(
40;1
no its a nice size for like kids 4ft5 or taller
40:1
winter- 5w30 summer-10w30
Not as easy as it is to call Yamaha with your serial number and have them tell you exactly what it is.
PW-80cc 2 stroke single cyl.kids dirt bike.
depends on a few factors. compression, carb jet, airflow and exhaust, you can reach 7 horsepower in the right conditions.
