Tuttio Soleil01 Calibrated: Specifically valved for the frame weight, battery payload, and rear swingarm geometry of the Soleil01 off-road electric motorcycle.

Heavy-Duty Coil Spring: Constructed from cold-wound, high-tensile steel designed to resist sagging and metal fatigue under the extreme compression loads of off-road trail riding.

Hydraulic Rebound Damping: Features an internal fluid-damped cylinder that controls the expansion rate of the spring, keeping the rear tire planted firmly on the ground for maximum traction instead of bouncing uncontrollably.

Reinforced Mounting Eyes: The upper and lower mounting points feature hardened steel bushings designed to withstand high-torque lateral forces and prevent mounting bolt sheer.

Corrosion-Resistant Finish: The shock body and spring are treated with a specialized UV and rust-resistant powder coating, protecting your electric bicycle parts investment from mud, water, and trail grime.
