Question: How Can I Make My 125cc Bike Faster?

What is faster 2 stroke or 4 stroke?

A stroke is a motion of a piston, meaning a two-stroke dirt bike has 2 different motions of the piston, while a four-stroke has 4.

2 Strokes are generally more unstable and accelerate faster, while a 4 stroke is more consistent and has a higher top speed..

How can I increase my bike torque?

Really the only way is to increase the displacement of the engine, ie increase its cc size by an oversize piston and rebore, or a longer stroke by a different crankshaft, connecting rod and piston. This allows more fuel to be ignited per power stroke, regardless of engine rpm, so increases torque.

What sprocket is best for speed?

For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear sprocket. For every 1 tooth that you change on the front sprocket is like changing 3 to 4 teeth on the rear (and that’s true for higher gearing ratios, too).

How can I make my 4 stroke engine faster?

One of the easiest ways to get a harder hit and better low-to-mid power is to increase the compression ratio. On a two-stroke engine, compression is increased by milling the head (which decreases combustion chamber volume). On a four-stroke, the compression ratio is increased by using a piston with a higher dome.

Is a smaller sprocket faster?

Gearing down by installing a larger rear sprocket (like with our YZ example) increases the final drive ratio and reduces top speed, but can increase acceleration. Gearing up, like with a smaller rear sprocket, decreases the final drive ratio and adds more top speed to your motorcycle or ATV.

How can I get more horsepower on my bike?

What does a smaller sprocket do?

Installing a larger countershaft sprocket creates higher gearing, while a larger rear sprocket lowers gearing. Similarly, a smaller front sprocket lowers the gearing while a smaller rear sprocket makes gearing higher. … For taller gearing, a one-tooth-larger countershaft sprocket is often the best bet.

Is a 125cc bike worth it?

125cc bikes are great for learning. Most of them are cheap to buy, forgiving when you make a mistake, and cheap to repair (you’ll make mistakes). They are generally quite light, which makes them easier to handle for beginners.

Do slip ons add horsepower?

Slip-on systems are the cheaper option and offer great value for the amount you spend. They basically just replace the stock muffler of the bike and are a popular upgrade for sportbikes. … On an average, the slip-on can increase your horsepower by 5% while reducing the weight of your bike by pounds.
