It reduces friction and wear on the piston/cylinder. Also reduces stress on the crank pin. The idea is used on some motocross engines and I think was originally tried by the Blackbourn motorcycle company many decades ago. Quote Link to comment Share on other sites More sharing options...

They are a production engine. Two types available, standard and baby. The baby one uses a much shorter con-rod. Quote Link to comment Share on other sites More sharing options...
