DR350S: Suspension

Lightweight, for reduced unsprung mass. Straight rate springs will give better control in the rough stuff. Sold in pairs.

• Rider and Gear up to 145 lb. = 0.47 springs → 24% stiffer than stock
• Rider and Gear 145-185 lb. = 0.52 springs → 39% stiffer than stock
• Rider and Gear 185-235 lb. = 0.58 springs → 56% stiffer than stock
• Rider and Gear 235-285 lb. = 0.63 springs → 66% stiffer than stock
• Rider and Gear 290 lb.-UP = 0.70 springs → 84% stiffer than stock

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.

This spring is 8.0kg/mm

OEM spring rates are 5.7-7.6kg/mm progressive style.

Stock suspension suffers from poor compression damping and limp rebound damping. The Race Tech Gold Valve allows you to tune both compression and rebound valving for vastly improved performance.

• Bolt-on shock valving for serious 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 DR350 shock linkage. Includes the lower shock bearing.

Quality replacement parts for servicing your shock.

• Shock shaft bushing
• Oil and dust seal
• Shock bumper
• Reservoir bladder cap

Complete kit of OEM quality parts to replace the bearings and seals in the swingarm pivot.

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.
