Test of the CRZ ERZ 450cc R Motocross

The CRZ ERZ 450cc R motocross bike is an impressive machine, designed to deliver top-level performance on motocross tracks. Not street legal. This motorized vehicle is intended exclusively for recreational and sporting use.

Engine:

450cc liquid-cooled, 4-valve single-cylinder engine with balance shaft.

The radiator is equipped with a fan to improve, accelerate, and ensure excellent cooling of the 450cc engine.

- POWERBOMB exhaust with stainless steel exhaust system

- Maximum power of 35 kW at 9000 rpm, equivalent to approximately 48 hp.

- Maximum torque of 40 Nm at 7000 rpm.

- 40mm carburetor with airbox
- Electric and kick starter for easy starting in all conditions.

- 6-speed gearbox for efficient power transmission.

Chassis:

- 54/60 mm diameter, 940 mm long, hydraulically adjustable inverted fork with compression/rebound damping, offering excellent shock absorption and stability.

- 465 mm long, adjustable rear shock absorber with compression/rebound damping and gas reservoir.

- 21-inch aluminum front rim and 18-inch aluminum rear rim with epoxy-coated hubs for maximum strength and lightness.

80/100-21 front tire and 110/90-18 rear tire for optimal grip on various terrains.

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

- High-performance hydraulic braking system with a 260 mm disc and dual-piston caliper at the front, and a 220 mm disc with a single-piston caliper at the rear.

In summary, the CRZ ERZ 450cc R is a high-end motocross bike, equipped with a powerful engine, high-performance chassis, and well-thought-out features to meet the needs of the most demanding motocross riders.

The advantages of the linkage suspension:

A linkage shock absorber increases the progression between wheel movement and shock absorber travel, improving riding comfort and suspension 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.
