Why I Love My 400EX 440 Big Bore Kit
As an avid ATV rider, I have always been on the lookout for ways to upgrade my machine and improve its performance. After much research and consideration, I decided to invest in a 400EX 440 Big Bore Kit for my ATV. And let me tell you, it was one of the best decisions I’ve made.
First and foremost, the increase in power and torque is undeniable with this kit. The stock 400EX engine is already impressive, but the added displacement from the big bore kit takes it to a whole new level. The larger piston and cylinder allow for more air and fuel to be compressed, resulting in a significant boost in horsepower. This means faster acceleration, better top speed, and improved overall performance on any terrain.
Another major advantage of the big bore kit is its durability. The stock engine can handle a fair amount of abuse, but with the added displacement from the big bore kit, it becomes even more resilient. This is especially important for off-road riding where your ATV is constantly being put through rough conditions. With the bigger piston and cylinder, there’s less strain on the engine components, making it less prone to wear and tear.
