Everything You Need to Know About Grom Big Bore Kits

One of the more popular upgrades is a larger bore. Big bore kits provide the ability to unleash more of the bike’s power by increasing the size of the cylinder and piston. This makes the engine more responsive and easier to ride.

However, there are several factors to consider before installing a big bore. First and foremost, you’ll want to make sure that your cylinder head, cam, and other modifications can handle the increased stress of a bigger displacement. It’s also important to remember that a bigger bore requires proper tuning to maximize its potential.
