CRZ ERZ 250cc PRO 4T 18"/21" Motocross Bike


The new 17hp air-cooled ERZ 250cc PRO from CRZ will captivate you with its large 18"/21" black aluminum wheels equipped with Gripsters front and rear.

Note: Not approved for road use. Motorized vehicle intended exclusively for recreational and sporting use.

Highlights of the ERZ 250cc
ZONGSHEN 250cc Engine: 12hp at 8.5kW (8500 rpm) — Powerful and reliable, this is the perfect Enduro engine for all skill levels.

Chassis: Reinforced tubular frame developed by the French brand CRZ with a removable rear subframe, often copied but never equaled, with a warranty of up to 2 years.

Braking: Its braking system consists of two 230 mm discs, gripped by a dual-piston caliper at the front and a single-piston caliper at the rear.

ERZ Racing Exhaust: Its full stainless steel system with POWERBOMB will allow you to gain up to 1.5 hp, improving the performance of the ZONGSHEN engine.

KKE Suspension: A top choice in the world of motocross, the 845 mm fork and 345 mm shock with 1000 lbs of travel offer excellent performance-to-price ratio.

Electric and Kick Start: Say goodbye to difficult starts thanks to the electric starter, which makes starting the ZONGSHEN engine easy.

Large 6.3-liter Fuel Tank: Essential for enduro riding, it allows for long, uninterrupted sessions.

Seat height: At 92 cm, and with 18" rear and 21" front wheels, this size is ideal for riders between 1.70 m and 1.90 m tall.

Pre-installed front and rear wheel gripsters improve traction, stability, and vehicle control on rough terrain by reinforcing the tire's attachment to the rim.

Advantages of the linkage suspension: A linkage shock absorber increases the progression between wheel movement and shock absorber travel, improving ride comfort and shock absorption. This explains the shock absorber's longer length compared to a conventional shock absorber.

Our motorcycles, quads, pocket bikes, etc., are not approved for use on public roads. Their use is strictly limited to closed, private tracks that comply with the provisions of Article R 331-21 of the French Sports Code.

Our vehicles (motorcycles, quads, buggies, etc.) intended for children should not be considered mere toys, but motorized machines belonging to the realm of motorsports, which involve inherent risks.

Minors under the age of 14 are not authorized to purchase, rent, or use non-approved vehicles, such as mini-motorcycles, children's quads, unapproved quads, motocross bikes, pocket bikes, pocket cross bikes, pit bikes, or dirt bikes. Their use is strictly limited to activities organized by approved sports associations, such as the FFM (French Motorcycling Federation) or UFOLEP (French Union of Secular Sports and Cultural Activities). It is important to note that the maximum speed of these vehicles on public roads is 24 km/h, which prohibits their use on public roads. Furthermore, minors under 16 years of age must be constantly supervised by an adult when using these machines.

To ensure your safety, it is essential to wear appropriate protective equipment, including an approved safety helmet, motocross-type safety glasses, gloves, elbow pads, knee pads, and a chest protector. It is also recommended to wear a long-sleeved top, long trousers, and high-top shoes that cover at least the ankle, ensuring that the laces are securely tied and away from the wheels, engine, and drive system.

You must register your machine with the Ministry of the Interior within 15 days of the purchase date. This process can be completed online at the following address: https://www.service-public.fr/particuliers/vosdroits/R20458. After submitting the declaration, you will receive an identification number to be engraved on the chassis and displayed on a visible plate. Please note that this plate can be removed during sporting activities.

We also encourage you to consult the charter outlining the rules to be followed for the use of your vehicle, available here: https://www.legifrance.gouv.fr/loda/id/JORFTEXT000020910287/, or to refer to the user manual, which you can download.

Assembling your bike:

You will only need to finish assembling a few easy parts (such as the handlebars, front wheel, and rear shock absorber).

Once assembly is complete, if the factory settings are not perfectly suited to your riding conditions, we invite you to visit our YouTube channel (Mini MX) where you will find both mechanical tutorials and bike assembly videos.

We recommend that you read the owner's manual and check the general tightening of your motorcycle (spokes, axle, general screws), chain tension, tire pressure, and the routing of the brake/clutch cables.

We recommend that you perform your first oil change using IPONE or Putoline oils, as recommended and approved by the manufacturer. Using other oils not approved by the manufacturer could damage the engine or gearbox.

Our after-sales service, based in Fréjus (83), France, is available at 0972390537 (free call) to assist you if you have any questions.
