Well, honey, a 140cc pit bike is technically 15cc faster than a 125cc pit bike. So, if you're looking to kick things up a notch and feel that extra 15cc power boost, go ahead and make the upgrade. Just don't expect to be breaking any land speed records anytime soon, darling.
how much hp is 140cc
about 350 pounds
There is no correlation between hp and cc, for instance, a 125cc motocross bike delivers around 25 hp, a 480cc briggs I/C flathead delivers 12 hp. The 140cc flathead lawn mower engines are between three and four hp.
like 70 to 90mph! = like 160khp
an 80cc to a 125cc depending on how much you weigh.
If you go on craigslist you can buy a 125cc for 300- 400.
The cost of an Orion bike depends on the specific model and the bike's condition. An Orion 125cc dirt bike, for instance, retails at around USD 1300 in 2014.
about 5hp
A 125cc engine can go about 45 to 50 miles per hour. The standard horse power of a 125cc motor is 9 horsepower but can very depending on the model of bike.
On average, a bike is about 3 to 4 times faster than walking.
well put it this way, if you rode a 125cc pit bike for an hour then got on an 85cc crosser, it would make you want to pay the extra £1500 for the crosser. they are so fast and much more reliable, but it depends what you want it for, if its for bombing round the streets then i would rather save £1500 and get a pit bike, but for proper racing then i would get a crosser, you really need the suspension and power in a race.
On average, a road bike is faster than a mountain bike by about 25 due to its lighter weight and smoother tires.
