The Motion Pro 01-2531 Throttle Kit is a direct replacement for the stock throttle system, making installation easy and straightforward. The kit comes with all necessary hardware for installation, as well as clear, easy-to-follow instructions.

In summary, the Motion Pro 01-2531 Throttle Kit is a high-performance upgrade for Honda TRX400EX and TRX400X models.
