RFN Thunder 70 Pro 70cc Pit Bike – Quick Overview
Best for: first-time petrol riders starting their off-road journey.
Engine: FH 70cc 4-stroke single-cylinder engine.
Gearbox: fully automatic — no gears, no clutch.
Wheels: 10 inch front / 10 inch rear setup.
Why parents choose it: automatic riding, electric start, hydraulic brakes and proper pit bike components.
Our view: the smallest and easiest RFN Thunder petrol bike for young riders starting out.
The RFN Thunder 70 Pro is the smallest petrol bike in the RFN Thunder range, built for young riders starting their first proper pit bike experience. With a fully automatic 70cc engine, electric start, hydraulic disc brakes and USD forks, it keeps riding simple while still feeling like a real off-road machine.
There are no gears and no clutch to worry about. Riders can focus on balance, throttle control, braking and confidence before moving up to semi-auto or manual pit bikes later.
This is the natural starting point in the RFN Thunder petrol range before progressing to the Thunder 110 Pro and Thunder 140 Pro.
My Take as a British MX Rider
The RFN Thunder 70 Pro makes sense as a first petrol pit bike because it keeps the controls simple but still gives the rider a proper bike underneath them.
The automatic gearbox is the key. No clutch, no gear changes and no stalling means young riders can focus on the basics first.
If the rider is new to petrol bikes and you want the easiest RFN Thunder option, this is the one to start with.
