Hello my friends. I own 3 Royal Enfields. 2022 650 Intercepter, 2023 Himalayan 411 and 2023 Classic 350.
I have FuelX lite in all 3. Here is my findings:
The 650, fuelX smoothed out the entire engine and gave easier top end speed. Speed is there with twist of the throttle.
The Classic 350, the fuelX took away some of the engine noise. The throttle is more responsive and gets up to 65-70 much faster and rides with ease.
The Himalayan 411, seems like the engine is running easier and like the 350, gets up to 65-70 much easier and I can stay at them speeds and the engine doesn’t feel like it’s struggling.
Now, I also have changed the exhaust and air intake covers to a wide opening cover. No DNA type filters, all OEM.
Doing the fuelX does improve in my opinion.
It does not make a 350 a 650. But, it smooths out the entire feel and ride.
I bought all my fuelX from Race Dynamics in India. 7-10 days for delivery. All my FuelX came with stickers, key chain and instructions.
Hope this helps!
