I was really excited to upgrade my XR400R with this kit, but unfortunately, the piston stopped working after just a few rides. I followed the installation process carefully, but it didn't hold up. I reached out for support, but no response yet. Very disappointed.

Decent Kit, Minor Installation Issues
The top-end kit works well for my TRX400X, but I had a bit of trouble with the installation instructions. They weren't super clear, and I ended up needing some extra tools. Once I got it set up, though, it's been running great! Just be ready for a little troubleshooting.

Strong Upgrade for My ATV
I installed this Niche top-end kit on my Honda Sportrax TRX400EX, and I’m thrilled with the results. The 397cc cylinder really gives it some punch. The performance difference is noticeable, and it runs smoother than before. Highly suggest for anyone looking to boost their ATV's power!
