CRZ ERZ MT 250cc 2-Stroke Liquid-Cooled Motocross Bike - 18"/21" 2025

CRZ is expanding its lineup once again with its new Enduro MT 250cc 2-Stroke liquid-cooled model! For those who always want more! More power, more thrills! Rediscover the pleasure of a reliable and robust 2-stroke engine. Not street legal. Motorized vehicle intended exclusively for recreational and sporting use.

This new CRZ ERZ 2-stroke enduro bike features the MT 250cc 2-stroke liquid-cooled engine! A CRZ exclusive, tested for two years to create the reliable and robust engine they're known for.

ZONGSHEN 250cc 2-Stroke Liquid-Cooled Engine

For the first time, CRZ offers an exclusive 2-stroke engine that delivers 30 hp and 30 Nm of torque, with a maximum power output of 26 kW at 8000 rpm (Remember: 1 kW = approximately 1.36 hp, so 20 kW x 1.36 hp = 27.5 hp)!

KTM 38 Carburetor:
CRZ equips the engine with a KTM 38 carburetor and features an electric starter for maximum ease of use. Of course, a kickstarter is also available for those who prefer it!

The KTM 38 carburetor is specifically designed to optimize the high performance of the MT 250cc 2-stroke engine. CRZ installs the original KTM 38 carburetor to ensure quick response and improved fuel atomization. Its improved floating chamber ensures stable fuel delivery, while its precise adjustments allow you to tailor the engine's operation to the specific needs of the 250cc 2-stroke.

6-Speed ​​Multi-Disc Wet Transmission and Clutch:

The power of your engine is efficiently transmitted through a 6-speed multi-disc wet manual transmission, guaranteeing smooth and responsive driving. This transmission system uses a 13-tooth sprocket, a 520 pitch chain, and a 51-tooth rear sprocket, with 6 hub bolts for increased robustness. Enjoy a reliable and high-performance riding experience, built to last.

High-Strength Steel Competition Frame with Double Central Tube and Engine Guard:

Balanced and reliable to handle the power of the MT 250cc 2-stroke and its 36 hp. CRZ installs the best on the market; this competition frame ensures unparalleled reliability! Have no doubt about the durability of the ERZ series' chassis.

The entire frame is made of high-performance tubular steel, the swingarm is steel, and the handlebars are profiled aluminum.

2-stroke exhaust system: What a pleasure to rediscover the sound of a 2-stroke engine! An exceptional sound.

KKE 910mm inverted hydraulic fork, adjustable for compression/rebound:

The front hydraulic fork is adjustable for compression/rebound, with a diameter of 53mm/58.5mm (large diameter) and a length of 940mm for 265mm of travel. It is, of course, an inverted hydraulic suspension.

This suspension will offer you true versatility for both enduro and motocross use.

Adjustable KKE 480mm rear shock absorber with remote reservoir on linkage:

CRZ offers you a truly high-quality chassis. The MT 250cc 2-stroke is the most accomplished motocross bike in its class, regardless of the competition. The KKE shock absorber with remote reservoir is 480mm with 120mm of travel. The remote reservoir is adjustable with a dial. Thanks to this, you are guaranteed that the damping performance will remain absolutely constant on all types of terrain.

Furthermore, this improves the damping response to offer exceptional control of the motorcycle's movements.

18" Rear and 21" Front Aluminum Wheels:

Consistent throughout the chassis, the aluminum wheels are equipped with rim locks on both the front and rear and fitted with 80/100-21" and 110/100-18" tires.

Dual-piston front brake and single-piston rear brake on 240mm discs: Braking is provided by a hydraulic system, with dual-piston calipers at the front and a single-piston caliper at the rear, both on 240mm discs. The braking performance of this CRZ system will surprise you, ensuring consistent and precise braking on all types of terrain.

520 chain drive: Equipped with a thick 520 chain for a factory-configured enduro setup, it features a 6-point sprocket.

94cm seat height: As high as a Honda CRF 250, this seat height is recommended for riders 1.75m tall and highly recommended for riders over 1.80m.

Advantages of the linkage mounting:

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