Single Ring Piston Kit Maico MC440 / MD440 '73-80

Wossner original bore

Sorry I have taken so long on a returning answer about your product.Of course a Wossner piston is very high quality.I did have to rejet of course , now the 1974.5 Maico 440 runs even better than it did before,& it ran great before. Wossner products are great,but the amazing thing I found were the individuals answering phone calls go way beyond the call of duty on helping customers any way they can. This I am most appreciative!! Thank you so much for your help & product, Robert Wood
