• 4 bearing pedal start engine
• Prepared for a case reed valve (with at least 2mm thick inlet gasket original carburettor can be mounted on original cylinder -> cat like non-cat) 
• Positioning pins for the housing halves 
• More threaded holes for ignition mounting (for more flexible ignition mounting) 
• Cooling fins for controlled temperatures 
• Optimised fluid chamber 
• No center stand mount (racing case) but instead you can mount a side stand
• Cylinder stud hole pattern 44mm x 44mm
• Diameter of cylinder neck is 48.4mm and can be spindled up to 53mm if no GME is used.

• Tip: Do you have an ADDY 50-1 A engine in combination with a Bing 15mm? Then use a 2mm inlet gasket. The standard inlet gasket is too thin. (see related products)
