ATHENA offers you this replacement piston for the top engine ATHENA Big Bore P400485100010 mounted on DERBI GPR, YAMAHA DT, DTR, TZR,... This piston will allow you to give your cylinder the original performance. Ideal in case of wear it is available in dimension A in 64.94mm and B in 64.95mm allowing to compensate the loss of compression due to the friction of the piston in the cylinder. This piston is delivered with its rings, pin and clips in C. We strongly advise you to mount the piston with new seals to avoid any compression loss. We recommend changing the piston every 10,000 km or 35 hours maximum!
