Actually HP can only be estimated . he HP depends on a lot of factors about the motor.
Displacement and HP are only related to each other in a range because of engine variations. I agree but was curious how did you get the cc of a lawnmower? If it is a lawnmower the hp comes out with an educated guess of about 12 hp.
The 176cc engines are about 5 hp; 160cc =3-4 hp 176 (foreign) 4-5 hp 205cc= 5-7 hp 250cc= 8 hp 350cc=11-13 hp
This is a poorly phrased question, but we'll assume you want to know a bikes top speed with a 250cc engine. First, there are many other factors that determine an engine's peak hp other than it's displacement. Top speeds are generally influenced by aerodynamics, gearing, grip, and force (HP). A rider can reduce air resistance by leaning forward on the bike. Weight will effect acceleration, not top speed. There are different 250cc motorcycles, CC = cubic centimeters, this is the capacity of the cylinders in the engine. There is no specific speed of a 250cc bike. you could have a 250cc dirt bike that goes about 60mph, or a 250cc Honda rebel that does 80. Hope this helps a little.
The normal size of a go cart engine is either 125cc or 250cc. These engines are either two stroke or four stroke engines and can produce as much as 90 hp.
how much cc's is a 6.5 hp engine
its the size of the engine in the motorbike.
it is 172mm long
On a exmark lazer z e-series 250 cc motor
Roughly 16.5 HP
Around 68 hp
Depends on the engine...
97 hp
