Its seat height is 92cm with a hydraulic fork of 840mm in 51/54mm inverted with 180 mm travel, its shock absorber on 450mm linkage with 90mm travel.
It also has a starter "lever" directly on the handlebar and therefore easily usable. The brake and clutch levers are adjustable and it comes with Pro Taper style grips.
Vertical 4-Stroke 300cc ZONGSHEN 22hp + 1.5hp for a total of 23.5hp: CRZ Exclusive, the new ZONGSHEN 4-stroke 300cc vertical engine of 22hp air-cooled is equipped with the new engine block and new clutch covers that are more efficient and more reliable, its exhaust full stainless steel with POWERBOMB boost of nearly 1.5hp bringing the engine to 23.5hp. Intended for experienced riders, it is not for everyone. Mini MX presents an ideal bike for cross use 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 Chassis: Its Adjustable Hydraulic Fork KKE 830mm with 51/53mm adjustment will allow you to adjust compression and rebound according to your use, preferences, and weight.
Stainless Steel Exhaust + PowerBomb (+1.5hp): An exceptional sound thanks to its full INOX POWERBOMB line, it is clearly a differentiating point. This configuration helps engine performance and will offer about 1.5hp more to the engine
Double piston Hydraulic Braking: The 230mm disc clamped by a double piston ensuring efficient 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.
KEE 840mm Hydraulic Inverted Fork: Often compared to the competitor FASTACE, the KKE brand offers you a high-performance hydraulic fork with 180mm travel and mounted on reinforced aluminum fork clamps of 51/54mm (large diameter), this original configuration will make a real difference compared to the competition!
KEE shock absorber on 450mm linkage: The CRZ ERZ PRO linkage mounting represents the most advanced design on the market. Both precise and reliable, it has often been imitated, but no replica matches its quality and precision. The 450 mm KKE shock absorber ensures perfect mass balance with the front suspension.
High Strength Steel Competition Frame with Double Central Tube: Balanced and reliable to accommodate the power of the ZONGSHEN 300cc and its 22hp +1.5hp with the PowerBomb exhaust. CRZ installs the best on the market for you, this competition frame guarantees unmatched reliability! Have no doubt about the durability of the ERZ PRO series chassis.
Seat Height 92cm - 18" rear and 21" front rims: This Motocross seat height is ideal for people measuring between 1.70m and above.
The advantages of the linkage mounting:
A linkage shock absorber increases the progressiveness between the wheel movement and the shock absorber travel, which improves riding comfort and suspension absorption quality. This explains why the shock absorber is longer than a shock absorber in a classic setup.
