Motocross Mini MX Big R 300cc 4T 18"/21"
The new Mini MX Big R 300cc air-cooled 22hp will charm you with its large 18"/21" black aluminum wheels equipped with Gripster tires at the front and rear. (Not approved for public roads. Motorized vehicle intended exclusively for recreational and sporting use.)
Its seat height is 92cm with an 840mm hydraulic fork in 51/54mm inverted and adjustable with 180 mm of travel, its shock absorber with 90mm of travel.
Vertical 4-stroke 300cc ZONGSHEN 22hp engine:
Its vertical 4-stroke 300cc air-cooled engine, its stainless steel exhaust. Intended for experienced riders, it is not for everyone. Mini MX presents here an ideal bike for cross and enduro rides.
The 300cc air engine develops 16KW at 8500 rpm for 22Nm (Reminder: 1KW = approximately 1.36hp so 16KW x 1.36hp = 22hp)
Its cycle part: Its 850mm hydraulic fork in 45/48mm will allow you to adjust compression and rebound according to your use, preferences, and weight.
Stainless steel exhaust:
An exceptional sound thanks to its full stainless steel line, this configuration helps engine performance.
Double piston hydraulic braking: The 230mm disc clamped by a double piston ensures effective braking.
5-speed oil bath gearbox:
Its gearbox is equipped with 5 speeds 1N2345 in a multi-plate oil bath, a feature that guarantees fast and precise transmission.
520 chain transmission:
Equipped with a thick 520 chain for a transmission originally configured for enduro, it is equipped with a 6-point mounting sprocket.
The assembly:
All our vehicles are delivered pre-assembled on a pallet by a specialized carrier.
You will only need to finish assembling a few easy parts (handlebar, front wheel, shock absorber axle (2 screws)…).
Once the assembly is complete, if the factory settings are not fully adapted to your environment, we invite you to visit our YouTube channel (Mini MX) where you will find both mechanical tutorials and vehicle assembly videos. Our Workshop remains at your full disposal to support you throughout your experience at 09.72.39.05.37 (Free Call), by email [email protected], or via online chat
