With geometry and kinematics studied, validated and titled in EWS competition by professional pilots, the Sunn Kern EN S1 is the ultimate weapon in Enduro. With an assertive design, it offers high pedaling efficiency and ensures real stability even at high speed. Unlike the Factory, Finest or S1 models, the Sunn Kern EN S2 has a robust and efficient 6061 aluminum frame, offering 150 mm of travel. Its “VR” kinematics, a virtual point of rotation that varies according to the depression of the oscillating arm, promotes pedaling at the start of the race and damping at the end of the race. Its progressive “LR” leverage ratio allows the bike to maintain a constant attitude and consumption of travel that is neither too fast nor too slow. For even more pedaling performance, the Kern EN S1 is fitted with a pair of 29 inch wheels.
Main features:
- Alloy 6061 frame, 150 mm travel.
- Shimano Deore 1×12-speed drivetrain.
- Shimano MT420 hydraulic disc brakes, 203/180 mm.
