This auction is for a brand new CUSTOM DESIGNED 12:1 compression Ratio 81mm big bore piston kit 13095M08100 for the 1988 thru 1991 Honda Hawk NT650 for use in the AHRMA road race series. 81mm is the largest bore size allowed by AHRMA. The only available piston kit from Wiseco is the K696 kit or singe piston # 4633M08200 which is 82mm and not legal for AHRMA competition. It is also not a race designed piston as ours is and only a 11:1 piston. The piston kit is manufactured by Wiseco for Andrews Motorsports and may fit other models but that is up to the buyer to determine.
