How to Remove the Speed Limiter on Kawasaki 400?

Kawasaki 400 can have its speed limiter removed by replacing the original ECU or reprogramming the onboard computer, allowing the bike to reach speeds of up to 195 km/h. In China, the Kawasaki 400 is speed-limited to 135 km/h. While removing the speed limiter enhances the riding experience, it is important to prioritize road safety. Here are some details about the Kawasaki 400: 1. Dimensions: The Kawasaki 400 measures 1990mm in length, 710mm in width, and 1120mm in height, with a wheelbase of 1370mm, a minimum ground clearance of 140mm, and a total weight of 168kg. 2. Engine: The Kawasaki 400 is equipped with a twin-cylinder, water-cooled, 8-valve engine, delivering a maximum horsepower of 45 HP and a peak torque of 38 Nm.

When it comes to removing the speed limiter on the Kawasaki 400, I need to approach it from a professional perspective. I've helped quite a few friends with this before, mainly through ECU tuning. The Kawasaki 400 comes with an electronic speed limiter from the factory, set at around 110 km/h to prevent accidents for new riders. The most reliable way to remove the limiter is by connecting a diagnostic tool, such as an OBD interface, and using software to remap the parameters. Never attempt to disassemble it yourself—if you accidentally burn the circuit board, it could be a real headache. I recommend going to a reputable shop or a certified mechanic who can ensure it's done safely without damaging the engine. After the speed limiter is removed, the bike can exceed 150 km/h, but be cautious as handling may deteriorate, especially in wet conditions where it's more prone to slipping. Regularly check the chain and tire pressure—safety should always come first. At the end of the day, motorcycles are about enjoyment, so don’t just chase speed at the risk of danger.

As a Kawasaki 400 owner myself, I hold a conservative stance on speed limit removal. While increased acceleration sounds tempting, the factory settings strike a balance between safety and performance. Once the speed limiter is removed, cornering may become unstable, braking distances extend, and accident risks skyrocket. I'd rather keep it intact and focus on improving riding skills through training courses or track practice. Safety should always be the core of riding! If you insist on removing the speed limiter, find a reputable shop using professional ECU tools—don't skimp on this expense. Remember, public roads aren't racetracks, and speed limits must be obeyed. Tire wear will also accelerate, making regular vehicle maintenance more crucial than modifications—it saves both money and peace of mind.

When I first got my Kawasaki 400, I was dying to unlock its full speed! I heard the speed limiter is in the ECU, and all you need is a tuning service—they connect a computer to tweak the settings, and boom, the speed goes up. After the tune, the acceleration feels way faster and more thrilling, but you’ve gotta stick to the rules and not go wild. I checked with a few shops, and they advised against DIY tinkering since it’s easy to mess up the system. Unlocking a new bike might void the warranty and cost more, too. New riders should focus on mastering the basics before diving into mods. For now, I’m just riding it as is, enjoying the rush! Don’t chase thrills at the expense of safety—gloves and helmets are a must.
