METEOR offers you this replacement piston for the METEOR top engine mounted on Aprilia Leonardo 150cc. Ideal in case of wear, it is available in dimensions A in 61.96mm, B in 61.97mm, C in 61.98mm, D in 61.99mmand E in 62.00mm, thus compensating for the loss of compression due to piston friction in the cylinder. The piston is supplied complete with rings, pin and clips. 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!
