A Racing Evolution
Building on the proven ER30 platform, the ER34 Racing takes E-moto shock performance further with a larger 34mm damping piston, wider shim stack, CTS compression tuning and a premium Kashima Coat® and DLC combination.
Key Features
- NEW 34mm damping piston, increased from 30mm
- 28% greater piston area
- Wider-diameter shim stack for increased tuning potential
- Kashima Coat® shock body – ~13% lower friction
- DLC-treated piston shaft – ~35% lower friction
- CTS compression tuning system with three valve options
- Hydrualic bottom-out technology combined with high-profile MDU bumper
- Three spring rates available for different rider weights
- Same external dimensions as ER30 for multi-brand compatibility
More Damping. More Tuning.
The 34mm piston increases piston area by 28%, providing greater hydraulic control and tuning potential. Combined with the wider shim stack and CTS compression tuning system, the ER34 offers a useful range of adjustment to dial in the shock for different riders, bikes and riding conditions.
Kashima + DLC
Kashima Coat® on the aluminium shock body and DLC on the piston shaft reduce friction at the shock’s moving surfaces while improving wear resistance. Kashima reduces friction by approximately 13%, while DLC reduces friction by approximately 35%, helping maintain smooth, consistent operation over time.
Made To Measure
The ER34 is designed specifically for lightweight E-motos, delivering the damping performance and adjustment range riders need without adding unnecessary size, weight or complexity. Easy to tune, easy to understand, and built to perform when the pace increases.
