New AlcoTech hydraulic Double Adjustment Valve EVO (DAV EVO) specifically developed for KAYABA shock-absorbers on YAMAHA YZ 250/450 F series (2014 > 2023). The new valve enhances control on compression high/low frequencies thanks to its improved flow sections: the internal screw works on low flows (30 click), the external hexagonal adjuster works on high speed flows (30 click). The cutting-edge and effective system allows perfect control and outstanding feeling to fine tune the suspension to any track/road condition and surface.
AlcoTech DAV-MT EVO compression valve:
increases rear wheel traction power;
improves bump compliance;
enhances progression and damping of shock absorber;
thermal balance (regular performance also in case of relevant temperature shocks)
