These are made to order and so cannot be despatched immediately.
These grooved flywheels are not available from Mamod Ltd. They are particularly suitable for the more powerful SP5 twin cylinder engine. They however fit the SP5 engine also but that has just one cylinder and so is less powerful. If you buy something you find unsuitable you can always send it back for a product price refund.
