WR250X: Suspension

Race Tech HP Springs have a high stiffness-to-mass ratio. In other words; the springs are light weight for their particular spring rate. This requires the finest materials and processing. Shot-peened and pre-set so they cannot sack out. All Race Tech HP Springs have the highest rate tolerances in the industry. These are the finest springs in the world-guaranteed.

OEM spring rate is .46kg. We offer stiffer spring rates from -5% to 10% for riders who wish to carry luggage or just prefer stiffer suspension.

• Race Tech's original bolt-on fork valving system for front cartridge forks
• Triple the flow area of stock pistons
• Put valving control on the shim stack

• Fork Maintenance and Gold Valve Installation" video all included

Kit includes all the fork bushings, o-rings, snap rings and washers. This kit comes with what you need to completely rebuild your front fork bushings.

• Bushings are dyno-tested to 500,000 strokes with less wear than OEM bushings
• Kit includes two slider bushings and two leg bushings

• Kit includes two fork seal snap rings

Low friction 'triple lip' seal design. Oil seals last 3-4 times longer that OEM seals. Kit includes fork seals and dust wipers.

Helps protect vulnerable fork tube and seal from dust, dirt, and corrosive elements. Hook & loop (Velcro) fastening on back side makes installation or removal for cleaning a breeze.

The little WRs have decent shocks but it can surely be improved with a Rear Shock Gold Valve from Race Tech. This will improve the damping in both directions and make the clickers more responsive to adjustments.

• Bolt-on shock valving for riders serious about suspension performance
• Improves control, traction, plushness and bottoming resistance
• Improved, long-wearing, low-friction sealing design decreases fade
• Includes complete instructions

Complete kit to replace the bearings and seals in the WR shock linkage. Includes the lower shock bearing.

Complete Swingarm Bearing kit to replace the bearings and seals in the WR swingarm pivot.

Kouba lowering link will lower the rear 0.80”. When combined with stock lowered clevis, lowers the rear a total of 1.75”.

Comes with bearings and seals installed for a quick and easy installation. Instructions included.

Disclaimer: Lowering the front and/or rear of your motorcycle will change the geometry and may affect the handling, use caution after making changes/adjustments.

Based on the wildly popular Race Tech Suspension Seminars taught by Paul Thede around the world, this step-by-step guide shows riders how to make their bikes handle like the pros. Thede gives the lowdown on all types of suspension, including cartridge and non-cartridge forks as well as dual-chamber and nitrogen-charged shocks.

The three forces of suspension, testing procedures, even the black arts of chassis geometry: This explains it all. The book provides step-by-step photos of suspension disassembly and assembly as well as a detailed troubleshooting guide for dirt, street and track.

• Extracts dirt and debris trapped between fork seal and tube
• Easy way to keep fork seals clean and debris free
• Works on conventional and upside-down forks

Showa removed the schrader valve on many newer rear shocks. Now you need a needle to recharge your shock with nitrogen after a rebuild. Race Tech built this unit just for that job.

The features of this tool include 300 psi capacity, bleeder valve and T-handle plunger pin chuck. Swivel chuck has a 12" flexible hose. Comes complete with instructions, carrying box and Schrader valve extension (required on some Showa shocks). Nitrogen bottles available at any welding supply house.
