Powertronic Fuel X Autotune Pro+ Review: Royal Enfield Goan Classic 350

Why the Fuel X Pro Plus?

We’ve used the Fuel X Pro Plus from Race Dynamics on our long-term Royal Enfield Himalayan 450 and Triumph Scrambler 400X. And it genuinely transformed both motorcycles – more so the H450, but the difference was telling on the 400X as well. Throttle response became linear, stalling disappeared, and the engine ran noticeably cooler.

Once we added a free-flow air filter and a decat, and dialled the Fuel X up to Level 10, the gains in performance, rideability, and overall feel were hard to ignore. It didn’t just improve things; it completely changed how the bikes rode. They became quicker to respond, easier to rev, and an absolute hoot to ride.

We’ve also used the simpler, cheaper Lite version of the Fuel X on the Hero Xpulse 200 4V. It helped—better cold starts, cleaner throttle response – but the jump wasn’t as pronounced.

So, when the Goan Classic rolled into our garage, we knew we had to put a Fuel X Pro Plus on it as well. The good folks at Race Dynamics were kind enough to send one over. And after using it for over a month – and many kilometres – here’s our take.
