BigBore Piston Kit 633ccm forged, 98.00mm, 10:1

BigBore Piston Kit

• Forged high-performance pistons for maximum reliability and power
• Despite the larger piston, the moving mass remains almost the same, so there is no need to adjust the flywheel mass
• The price includes a piston, a set of rings, the piston pin and two piston pin clips
• Please order the BigBore cylinder head gasket separately
• The compression values are given as approximate values
• For an increase in compression, additional measures (ignition/carburettor tuning, combustion chamber modification) may be necessary
