TSO Garage Note
A top-tier replacement option when scoring, wear, or detonation destroys a junior mini-bike top end. Instead of dealing with the downtime and variable quality of replating a worn-out stock bore, this ready-to-bolt-on cylinder delivers exact factory port geometry and hard-wearing nickel silicon carbide plating to keep high-strung 50cc engines running strong race after race.
