Tornado BRX V3 21/18 : the 250cc 4-stroke dirt bike for demanding adult riders
The 250cc dirt bike Tornado BRX V3 21/18 by Nitro Motors is built for adult riders who refuse to compromise on power, agility or durability. Its 4-stroke 250cc engine (12 kW / 7,000 rpm), hydraulic USD fork and hydraulic disc brakes (Ø230 mm front, Ø190 mm rear) make it a benchmark machine for circuit and private land use. Not road-legal — off-road use only. Browse our full range of adult motocross bikes.

V3 design and reinforced frame : the 250cc dirt bike that commands respect on track
The Tornado BRX V3 stands out immediately. Its reinforced steel tube frame and aluminium swingarm deliver optimal rigidity to absorb jumps and tight corners without distorting geometry. The 21" (front) and 18" (rear) wheels with reinforced aluminium spoked rims give it competition-machine aesthetics. Seat height 84 cm and dry weight 110 kg provide the perfect balance between high-speed stability and technical section agility. Max payload: 90 kg. Protect every ride with an approved helmet.
250cc 4-stroke engine 12 kW : calibrated power for your adult dirt bike
The heart of the Tornado BRX V3 beats to the rhythm of a 250cc 4-stroke single cylinder, delivering 12 kW at 7,000 rpm through a 5-speed manual gearbox. This air-cooled block delivers torque available from low revs — ideal for corner exit re-acceleration and varied terrain sections. The 12V electric starter (maintenance-free gel battery YTX5A-BS) is backed up by an emergency kick-starter. Estimated consumption ~2.5 L/h (tank ~6.5 L). XtremRS tip: first oil change at 5h of use with 10W-40 semi-synthetic oil.


USD fork and hydraulic disc brakes : competition-level safety for this 250cc dirt bike
The Tornado BRX V3 features a hydraulic USD (Upside-Down) fork at the front, paired with a rear hydraulic shock with adjustable oil pressure. This duo absorbs the most violent jump impacts and holds the line precisely in technical sections. Braking is handled by hydraulic calipers on ventilated discs Ø230 mm front / Ø190 mm rear, delivering progressive and precise stopping power even on wet ground. An emergency kill switch on the handlebars completes the active safety system. 2-year manufacturer warranty included.
428 chain drive : constant reliability and performance for your 250cc dirt bike
The Tornado BRX V3's drivetrain relies on a high-strength 428 chain (15/48T ratio), engineered to withstand hard acceleration stress and muddy terrain. The adjustable chain tensioning system eliminates any risk of derailment under extreme conditions. The stainless steel exhaust, optimised for gas flow, unleashes the full power of the 250cc engine while guaranteeing durability and resistance to high temperatures. Maintenance recommendation: lubricate the chain after every ride and check tension every 500 km. 2-year warranty included.
