ATHENA offers you this replacement piston for the ATHENA P400210100071 top engine fitted on your HONDA CRF 250cc. Ideal in case of wear, it is available in dimension A in 87.95mm, B in 87,96mm thus allowing to mitigate the loss of compression due to the friction of the piston in the cylinder. This piston is supplied with rings, pin and clips in C. We strongly advise you to fit the piston with new seals to avoid any loss of compression. We recommend changing the piston every 10,000 km or 35 hours maximum!
