MX-TECH Low-Friction Shock Piston Ring Kit SHOWA 50 mm for HONDA, KAWASAKI, SUZUKI and BETA 2001-2026

The MX-TECH SHOWA 50 mm PB01SHPB-0001 shock piston ring kit is designed for SUZUKI RM 125, RM 250, RMZ 250, RMZ 450, HONDA CR 250, CRF 250, CRF 450, KAWASAKI KXF 250, KXF 450 and BETA RX 300, RX 450 from 2001 to 2026. The shock piston ring (piston band) seals between the piston and the body: the oil has to pass through the valves, not around the piston. This kit replaces the original ring with a low-friction ring fitted over an O-ring.

Specifications

• Brand: MX-TECH
• Manufacturer part number: PB01SHPB-0001
• EAN code: 01000120
• O-ring included

When to replace it?

• Piston ring worn or scored at service.
• Damping that fades as the shock heats up.
• Shock service or tuning.

Check the make and the piston diameter of your shock (in the name). This job is done with the shock taken apart and drained of nitrogen: it is meant for workshops and properly equipped mechanics.

Fitting tips

1. Release the nitrogen and take the shock apart following the manual.
2. Remove the old ring from the piston without scratching the groove.
3. Fit the O-ring and then the ring, refit the piston and bleed the shock before recharging the nitrogen.
