Description
RFN Thunder 110 Pro 110cc Pit Bike – Quick Overview
Best for: riders stepping up from smaller automatic bikes.
Engine: FH 110cc 4-stroke single-cylinder engine.
Gearbox: 4-speed semi-automatic — no clutch lever needed.
Wheels: 14 inch front / 12 inch rear pit bike setup.
Why riders choose it: more power than the Thunder 70, proper 14/12 sizing, hydraulic brakes and easy semi-auto progression.
Our view: the natural middle step in the RFN Thunder petrol range before moving to the full manual 140 Pro.
The RFN Thunder 110 Pro is the middle bike in the Thunder petrol range, sitting between the smaller Thunder 70 and the full manual Thunder 140 Pro. It gives riders more power, a bigger chassis and their first proper experience of gears, without needing to use a clutch lever.
The semi-automatic gearbox is the key selling point. Riders can learn gear selection and build confidence without the added pressure of full manual clutch control.
With 14/12 wheels, hydraulic disc brakes, USD forks and a proper pit bike chassis, the Thunder 110 Pro is a serious upgrade for riders who have outgrown smaller automatic bikes.
My Take as a British MX Rider
The Thunder 110 Pro is the sensible middle step in the RFN Thunder range.
It gives riders the feel of a proper pit bike with bigger wheels, more power and hydraulic brakes, but the semi-auto gearbox keeps the learning curve manageable.
If the rider has outgrown the Thunder 70 but is not ready for the full manual 140 Pro, this is the one I’d look at.
