MXT National Shock for Honda CRF 250 (18-21), 450 (17-20)

MX-TECH National Shock

The MX-TECH National. This shock is equipped with the best technology, uses the best coatings and has the most adjustability of any shock currently available. Handmade in the USA.

MXT adapted the professional grade National platform to the latest Honda bikes, offering key benefits:

            - Light weight

            - Low friction parts (with genuine Kashima and DLC coatings)

            - SKF seals

            - 5 way adjustability

            - Membranefree piston with Tankreservoir

            - Huck Valve speed sensitive bottoming control

            - High quality materials

Light weight: The key to a professional grade product is to reduce the weight. MXT chooses the best alloys available. The net result contributes to less fatigue for the rider.

Low friction: This is achieved by not cutting corners. Many suspension manufacturers reduce costs by speeding up the machining process and altogether skipping critical finishing steps. Once a part is complete, various coatings are added to protect where best suited. Critical parts are shipped to Japan for Genuine Kashimacoating, other parts (like the shock shaft) are DLCcoated for low friction and longevity. Finally, the remaining parts are anodized for a combination of aesthetics and protection of the parts.

SKF Seals: MXT was the first to recognize and proudly distribute SKF motorcycle seals in the US direct from Italy. We are thrilled to collaborate with SKF to make custom seals for the National. SKF is the standard in reliability.

5 way adjustability: Adjustability means riders can setup their suspension to better match the terrain. The shock ships with a tuning guide – and we are only a phone call away.

   - High Speed Compression

   - Mid Speed Compression

   - Low Speed Bypass

   - Low Speed Rebound

   - Mid Speed Rebound

Membrane Tank: OEM shock reservoirs use a nitrogen bladder that leaks gas into the oil over time. This results in many issues, like the shock performance changing over time – making it difficult to even stay consistent thru the duration of a race. Another issue is that the service interval times are shorter.

The MXT membrane free piston offers the comfort and zero friction characteristics of a bladder, but keeps nitrogen separate from shock oil. This prevents premature wear like oxidation and cavitation. 

Huck Valve: This component gives the riderspeed sensitive bottoming control of the shock. The shock resists full travel and prevents the “hard stop” found when a shock bottoms out. This helps the rider to avoid the shock from deflecting energy to the side and swapping out. This feature is especially helpful in deep rolling whoops. Plus, the additional compression damping also adds significant rebound damping force – giving the rider more time to react to a full impact before a shock recoils. The Huck Valve is designed to be speed sensitive, meaning the active movement transitions smoothly even with sudden mid-stroke acceleration. Finally, this feature is tuner friendly and adjustable for rider preference via shims.
