WÖSSNER Forged Piston - Ref. K4023DA-2
Piston designed by Wössner for urban engines, forged from aluminum and precisely machined in Germany. This piston is intended for demanding modifications and careful replacements: friction-reducing skirt treatment, tight dimensional finish, and delivered with all necessary accessories for installation.
The forging process gives the piston better homogeneity and superior mechanical strength compared to a cast piston, making it a relevant choice for TMAX and other sporty scooters seeking reliability and endurance of the moving group. The oversize A implies a precise fit to a bore of 68.00 mm — check the condition of the sleeve and the piston/cylinder clearance before installation.
Main compatibility: Yamaha T-MAX 530 (SJ09, SJ14 - models 2016, 2018, 2019). Manufacturer reference: K4023DA-2.
