More on Pistons and Cylinder Kits

Here we talk more about the differences in pistons especially the JOG versions 10mm and 12mm

More on the Pistons we sell

At MRP we offer several JOG pistons from 40mm, 41mm, 47mm, and 48mm please make sure to order the correct replacement or big bore option. If repairing a 40mm cylinder you might want to consider reboring it and using a 41mm JOG piston, for racing upgrades you can go to 47mm cylinders or 48mm cylinders. The 48mm JOG Yamaha Minarelli Piston 72cc N-MP-09464P is a good replacement for the N-MP-09464 kit or a 47mm cylinder that is damaged. You can find out more about our Yamaha pistons from Taiwan at
