Krooz Racing Performance Suspension Kit for the Honda CRF450/250 model bikes is designed to enhance the performance and handling of your Honda CRF 250 or  450 motocross bike.

Kit includes the following components and fits 2022/23 Honda CRF MX machines:

 

  1. Honda Billet Rear Linkage Assembly: This assembly includes the delta and linkage arms for the rear suspension. The linkage system helps improve the rear suspension's performance by providing smoother acceleration and plusher first bump touch, increased stability when entering turns, and better absorption of big bumps.

 

  1. 50mm CRF Rear Shock Piston: The kit includes a 50mm rear shock piston with specifications tailored to the CRF450/250 bikes. The rear shock piston enhances the shock's performance, allowing for a more controlled and tuneable setting. It contributes to a less spiky action and improved big bump absorption.

 

  1. Factory Style Alloy Nitrogen Bladder Cap: The kit also features a factory-style alloy nitrogen bladder cap. This cap is designed to provide ease of gassing via shrader valve and is extra O-ring sealed to prevent leaks. It ensures a secure and reliable seal for the gas bladder and in a colorway that finishes off the shock build. (Red or Blue)

 

  1. Dirt Clearing Spring Seat: This component helps prevent debris and dirt from interfering with the spring's performance. This dirt build up is notorious in the OEM spring Cup . Our krooz racing kit ensures optimal function and longevity of the rear suspension bottoming system reducing the amount of dirt and rocks constantly getting rammed into the dust cap and sealhead on bottom out.

 

  1. Showa 49 Fork '32' Piston Kit: This piston kit is designed to eliminate harsh feeling and offers a more controlled and tuneable shim setting. It enhances the front fork's bump action, providing a smoother and more responsive ride.                                                                                                                                                       
  2. Fork and Shock Setting/Build sheets with multiple setup options - A, B, Vet/Jnr A, Jnr C/B, Offroad 

 

*Available in both Red and Blue colorway (bladder cap and spring seat)

 By combining the complete linkage system, shock piston, and the front fork piston kit, this setup kit aims to offer improved overall bump action from front to rear especially reducing harsh spikes whilstoffering great value in this bundled package.  

Of course , Custom setting is available  for best results.  Simply email info@krooztune.com after ordering this kit and we can recommend the best available setting and pre arrange / install to parts to match your needs.  Full specification sheets are included.
