TECNIUM Segment Set Ø47.75mm Yamaha / BW80 (manufacturer ref: PSR-YB80-075) — a set of segments designed for the refurbishment of light cross and motocross engines. This Tecnium kit is aimed at riders who want to restore piston sealing without replacing the entire cylinder-piston assembly.
The segments ensure the connection between the piston and cylinder: their proper sealing is essential for compression, throttle response, and a crisp start. Ideal for targeted refurbishment of your PW80 or for replacing worn segments after long off-road sessions. Before installation, check the condition of the piston and bore; a heavily marked cylinder requires additional treatment.
Main compatibilities: YAMAHA PW 80 (2009, 2010, 2011 - 80 cm3). A practical spare part for regular maintenance, this Tecnium segment set allows you to seriously upgrade the engine core while maintaining the racing philosophy of small displacement cross bikes.
