KKE Upgraded Rear Suspension Shock Absorber | By KKE | For SurRon Ultra Bee Electric Dirt Bike
This upgraded KKE rear shock is a serious performance improvement for the SurRon Ultra Bee, built for riders who want more control, better support, and consistent damping across aggressive trail and mixed riding. KKE designed this shock around a large 40mm bore and a 500lb spring rate, giving the Ultra Bee a much more planted feel under acceleration, braking, and repeated hits.
Every major component is CNC machined from high-grade aluminum alloys, with a hardened and chrome-plated piston rod and professionally calculated oil channels to keep damping predictable and fade-resistant. Internal hydraulic cushioning and upgraded all-metal internals further improve durability and long-term performance, especially for riders pushing the bike harder than stock suspension allows.
